What Are Exogenous Ketones: When And How To Supplement With Ketones

What are exogenous ketones and what are their health benefits? Get the details with this in-depth guide to supplementing with exogenous ketones.

Exogenous ketones are one of those products that seem too good to be true. You can just take a pill or a powder and instantly get the benefits of ketosis?

But what exactly are exogenous ketones and how exactly do they work? If you’re interested in the benefits of a ketogenic diet, exogenous ketones are definitely something to look into. Which is what this guide is all about. 

Exogenous ketones come in different forms and you can use them for different purposes, from reducing keto flu symptoms to enhancing physical and mental performance. 

Read on for in-depth info about the different types of exogenous ketones, how they work, how to take them, and more.

WHAT IS KETOSIS?

If you are new to ketosis and don’t know much about it, it is a metabolic state where your body preferentially uses ketones (instead of glucose) for energy.

This can lead to a host of different health benefits from lowering chronic inflammation to fat loss and muscle maintenance. If you’d like to learn more about ketosis, what ketones are, and how to benefit from these, feel free to read through our guides:

TYPES OF EXOGENOUS KETONES

If you’ve read the guide about ketones, you’ll know that there are three different types of ketones your body can make in the absence of carbohydrates, typically from stored fat. They are: 

However, there are ways to get ketones easily from exogenous (outside of your body) sources.

Beta-hydroxybutyrate is the active ketone that can flow freely in the blood and be used by your tissues, so that is the one that most exogenous ketone supplements are based off. 

Ketone Esters

Ketone esters are in a raw form (in this case, beta-hydroxybutyrate) that is not bound to any other compound. Your body can use these faster and they’re more efficient at raising blood ketone levels because your body doesn’t have to cleave the BHB from any other compound. However, there are some trade-offs.

Most users of traditional ketone esters claim they don’t enjoy the taste, to say the least. Gastric distress is also a very common side effect.

Ketone Salts

Another form of exogenous ketone supplements come in the form of ketone “salts.” This is where the ketone body (again, typically beta-hydroxybutyrate) is bound to a salt — usually sodium, calcium, magnesium, or potassium.

While ketone salts do not raise ketone levels as quickly as ketone esters, the taste is much more palatable and the potential side effects (like loose stools) are lessened. This is the type of ketone supplement that works well just a majority of the population.

It comes in powder and capsule form.

MCT Oil and Powder

MCT (medium chain triglyceride) oil, and other medium- to short-chain fats can be used to help boost ketone production as well, albeit through an indirect pathway.

Whereas your body can use beta-hydroxybutyrate from ketone salts or esters immediately for energy, your body has to transport MCTs to your cells to be broken down. From there, your cells make ketone bodies as a byproduct and only then can you use them for energy.

MCT oil is a great way to get extra fat into your diet. It’s tasteless and versatile, so you can use it on everything from your salad to your morning latte.

The downsides to MCT oil for ketone production is that too much MCTs can result in an upset stomach[*]. Anecdotally, fewer people experience stomach upset with MCT powder.

MCT oil and powder are also calorically dense compared to ketone supplements, so opt for exogenous ketones if you’re watching your caloric intake.

WHY EXOGENOUS KETONES?

There are times when eating a fully ketogenic diet is not realistic or when you want to get the benefits of a keto diet without restricting carbs as much.

Here are just a few reasons why you might want to try exogenous ketones:

  1. When keto is too restrictive and you eat a few more carbs than you should. Exogenous ketones can provide you with the energy and mental clarity of keto without the restriction.
  2. Holidays and travel when a strict keto diet isn’t as realistic.
  3. When your energy is low — usually when you’re first transitioning into ketosis. Exogenous ketones can give you the boost of mental and physical performance you need.
  4. In between keto meals for more energy and mental clarity.
  5. For athletes who typically rely on carbs for performance. BHB powder or pills can offer a clean, efficient form of energy that can fuel your training sessions and allow you to stay in ketosis, unlike carbohydrates.
  6. If you eat too many carbs, you can take exogenous ketones to get you back into ketosis rapidly instead of waiting 2-3 days.

5 Reasons To Use Exogenous Ketones

#1: May Stimulate Weight Loss

Weight loss is probably the number one reason most people want to get into ketosis. Taking exogenous ketones doesn’t make you magically burn fat, but it does get you into ketosis quickly.

Exogenous ketones stimulate weight loss by increasing energy and decreasing hunger.

How to: Use a scoop of exogenous ketone powder or 1 dose of BHB capsules to help transition into ketosis or to boost your body’s ability to utilize ketones and stored fat as energy.

#2: To Get Back Into Ketosis Quickly

Not everyone can follow a very strict, high-fat, low-carb diet. For those who have done keto before, you’ll know that when you get kicked out of ketosis, it can take a while to get back in.

Not anymore. You can use exogenous ketones to put your body back into ketosis quickly and easily.

Using an exogenous ketone supplement shortly after a meal with carbohydrates will tell your body that it’s time to use ketones for energy instead of relying on carbs in the near future. Instead of eating very-low-carb for days after a carb binge, you can just take a scoop of exogenous ketones or a few days of BHB pills and get back into ketosis.

This also means you don’t have to go through the keto flu again if you happen to have the occasional carb relapse.

How to: Take half to a full serving of exogenous ketones when transitioning to ketosis.

#3: To Avoid The “Keto Flu”

When you transition from eating lots of carbohydrates to the ketogenic diet, unwanted side effects can occur.

These often include low energy, bloating, irritability, headaches and fatigue. This is because your body is “in-between” burning carbs and burning ketones and hasn’t gain efficiency producing ketones from your fat stores and using them for energy yet.

The good news is that you can use exogenous ketones to bridge the gap. While your body is getting used to producing ketones, you can supply it with energy to eliminate with the common side effects of your keto transition.

How to: Split into smaller doses of 1/3 – 1/2 scoop or a 1/3-1/2 dose of capsules and spread throughout the day for 3-5 days while transitioning to ketosis.

#4: For Endurance Exercise Benefits

When your body faces the energy demands of physical activity, there are three different energy systems it can use. Each requires different types of fuel.

If you engage in explosive activities, such as sprints or quick movements, your energy comes from ATP (adenosine triphosphate). This is a high-energy molecule your body stores for future use. However, your body only has a certain amount of ATP available to use for explosive movements, which is why you can’t be maximally explosive for more than 10-30 seconds.

When you run out of ATP, your body begins making energy from glycogen, circulating glucose, or free fatty acids. Some of these processes are dependent on using oxygen for energy. However, when you take exogenous ketones, your body can use that energy immediately with lower oxygen utilization.

This translates well to endurance exercise performance, where a big limitation is the amount of oxygen that is available for metabolism (VO2max).

How to: Take a single scoop before a workout that will last 45 minutes or longer. Take another 1/2 scoop for each additional hour. This is a winning strategy for training sessions as well as competitive marathons, triathlons, and ultra runs.

#5: For Mental Productivity

Your brain has a very effective way of keeping foreign substances out. This is called the blood-brain barrier. Because your brain consumes 20% of your body’s overall energy, you need to make sure it is fueled appropriately.

Glucose can’t cross the blood-brain barrier by itself — it relies on glucose transporter 1 (GLUT1). When you eat carbs, you get swings in the energy that is available to cross the blood-brain barrier using GLUT1. And it’s these swings that lead to bouts of energy, followed by periods of brain fog.

Ever feel mentally foggy after you eat a super dense carb meal? That is the dip in energy and a ton of metabolic processes trying to shuttle glucose around your body. No one wants to feel mentally foggy, so good thing there are exogenous ketones.

Ketones, however, are transported by a different type of transporter: monocarboxylic acid transporters (MCT1 and MCT2). Unlike GLUT1, MCT1 and MCT2 are inducible, meaning that they become more efficient when more ketones are available[*]. 

You can have a constant supply of energy to your brain just by taking more ketones, with no other processing needed.

But if you’re not always in a state of ketosis, you won’t always have a supply of ketones to the brain. This is when you can take exogenous ketones.

Think of one of the benefits of exogenous ketones as on-demand brain fuel. If you need some mental energy, you can take exogenous ketones on an empty stomach and they will readily cross the blood-brain barrier and be used as such.

How to: Take a scoop of exogenous ketones or 1 dose of BHB capsules on an empty stomach for 4-6 hours of mental energy enhancement.

The Takeaway: Use Exogenous Ketones for Energy, Ketosis, and Performance

As you can see, there are plenty of ways to use exogenous ketones for a variety of benefits.

You can take ketone esters or salts, although salts tend to be more palatable. In fact, some ketone salts come in different flavors and mix easily into water, coffee, tea, and smoothies.

  1. Hi! I noticed I’m not sleeping well at all while taking one scoop a day. Should I be taking the scoop in the morning vs the afternoon?

    1. Hey Jennifer! There are no stimulants in this product, however it does supply your body with ready to use energy. Many supporters take this at night and even before bed for brain food while they are sleeping, but everyone is different. We suggest trying both and see how you feel!

  2. Hello, I’ve tried several different Exogenous Ketone supplements and I believe Perfect Keto may be the best I’ve tried. Thus far I’ve had Keto//OS from Pruvitt, Kegenix, KetoForce, KetoCaNa and Ketond. Out of all these brands both Perfect Keto and Ketond have been the products that hack me into Ketosis quick and for longer periods of time. Perfect Keto is less expensive that Ketones from Pruvitt mainly because Pruvitt and their Network Marketing is all about making money. The flavors of Perfect Keto are much better than Pruvitt.

    1. Agree 100% pruvitt is outrageous and the flavors while they are getting more palatable are still not easy to get down , and I actually started on Justins Bakery ketones , those were very inexpensive but absolutely rancid !! Thanks for this comment I’ll definitely try this brand…

    2. Hiiiiiiii-The first Keto product I tried was the Keto OS/Pruvit stuff.I really struggled to get it down.The taste was so”Over The Top Sweet”,even after adding close to 100mls of lemon juice.The price was also very OTT!I love the Perfect Keto products,a lot easier on the wallet as well as the pallet

  3. Been using yur stuff for the last week and tyere is absolutely no change in the amount of ketones based on the ketone strips i use to monitor ketone levels. I use another product as well and switched back and have sustained higher levels of ketones most of the day. Is there a reason that your product doesnot produce the results based on the strip test? I am a larger guy, 260 possibly need more? I have 2 tubs to go through and am not overly optimistic about whats going on.

    1. Hi Rob thanks so much, many people experience inconclusive results from the pee strips, as the ketone concentration in our pee is a measure of ketones not being used by the body. Basically the overflow or unused ketones. As our body becomes more adapted to using ketones, there will be less in our urine. It’s tough to keep the variable constant of how hydrated you are across many pee tests. Don’t be discouraged by pee test results. We have had many times where our blood tests show 1-3mmol/dl BHB but our pee test showed no results. Definitely keep testing (consider using a precision Xtra) and changing the dose to suit your needs. Hope this is helpful!

    2. Ketostix are very unreliable. There are many factors which can alter results such as hydration level, if you’ve worked out recently and the amount of unused ketones in your body to name just a few. Never rely of Ketostix to determine whether you are in ketosis or not. The Precision Xtra blood ketone monitor is the gold standard for testing for ketones in your body. After following a ketogenic diet for a while, you should be able to tell if you are in ketosis or not by the way you feel.

  4. Hey There. I found your blog using msn. This is a very well written article. I will be sure to bookmark it and return to read more of your useful info. Thanks for the post. I’ll certainly comeback.

    1. Hi Nikki, 15 scoops come in a tub. The serving size varies quite a bit for individuals. We recommend starting with a 1/4 to 1/2 scoop and moving up from there and adjusting the time and amount to what works best for you.

      1. Thanks ya I am using half a scoop will have to order more next week cause the hubby desiderate to join me in loosing weight so want to try the peaches and cram next lol

  5. Heya i’m for the primary time here. I found this board and I find It really helpful & it helped me out a lot. I am hoping to provide something again and aid others like you aided me.

  6. Can I just say what a relief to find an individual who essentially knows what theyre talking about on the internet. You certainly know how to bring an concern to light and make it critical. More folks should read this and comprehend this side of the story. I cant believe youre not more well-liked due to the fact you absolutely have the gift.

  7. what the heck lol not bread . Read !!!read this would help get past the discouraging phase of keto flu. I’m on a fire dept can’t really be down on energy . so is this shake a meal replacement .Just want to be able to get into ketosis quickly .What would you recommend I start with

  8. i am kind of confused when and how to take the product
    is it once a day ? is it only if you ate something carby? sorry that i’m not very clear on this, but – i could use some advice? thanks!

    1. Slowly ramp up your ketone intake. Be patient! 🙂 For many of us, our bodies aren’t used to running on ketones, so you can expect an adjustment period. Try ¼ scoop first. Transitioning to ketosis removes water from our bodies, so getting lots of water will help with any dehydration and stomach issues. Ramp up from there, trying ½ scoop the second week or when you feel it’s appropriate, and then try a whole scoop 1-2 weeks in. You can use it for extra energy or to help get into ketosis if you aren’t there already. Most people use it 0-3 times per day.

  9. I was introduced to the product by a friend to help me with energy and mental focus. I then learned about the ketogenic diet and am now a month into it. I started working out again and my buddy suggested more exogenous ketones … my weight loss stopped and is now going up. 🙁

    Should I be taking exogenous ketones while on a ketogenic diet? Or only when I do cardio to help with energy.

    Thanks
    Mark

    1. Great question. So if you are already in nutritional ketosis from your diet, exogenous ketones would still help raise ketone (energy) levels when you want that (maybe for focus at work or energy at the gym. They also help get you back into ketosis after cheat meals and skip the “keto flu” which is the period when your body is using up stored glycogen.

      1. Do you have to be on the Keto diet to try this product? Im needKetones try something to help with energy and staying focused. Ive tried B2 and B12 supplements for quite awhile with no change in either area so I would like to try this without having to make a drastic change in diet.

  10. Thank you a bunch for sharing this with all of us you actually understand what you’re talking approximately!
    Bookmarked. Kindly additionally seek advice from my website =).
    We will have a link trade agreement among us

  11. Just found your site….wondering how you take the Peaches & Cream Keto powders…simply mix with water?

    1. The best way to drink Perfect Keto is however it’s best for you! Many of our customers love the following options:
      Heavily diluted in ice water
      Mixed with MCT Oil Powder (this is great for creaminess and added healthy fats)
      Mixed in ice coffee with cream
      Blended in almond milk or coconut cream

      We recommend a ¼ – 1 full scoop of our exogenous ketones mixed with 8-12 oz. of water or your favorite beverage. Chocolate Sea Salt goes well with coffee and Peaches and Cream with smoothies. Some people even make ketone popsicles! We encourage you to get creative.

      1. I have been blending a full scoop with heavy whipping cream, ice, water and MCT oil, first thing in the morning. Is this ok to do? I was thinking I could boost my fat intake while drinking Perfect Keto. It comes out like a frothy breakfast shake.

  12. I’m new to the Perfect Keto. I’ve been using a full scoop in the morning with my coffee. I am using it mainly to stay in keto for weight loss. I am eating flax meal and chia seed “noatmeal” with it. Should I be fasting or will I still lose weight eating low carb with it?

    1. Great question. We can’t see any reason this can’t be a part of a successful weight loss program on the ketogenic diet. In the morning with coffee is a very popular way to raise ketone levels in the morning. See if you are on pace with your goals and perhaps try a week with a different breakfast to see what feels best. Also – new article might be helpful here too: https://perfectketo.com/exogenous-ketones-for-weight-loss/ Good luck! 🙂

  13. There is something that does not make complete sense about this.

    I understood that endogenous ketones are produced when you force your body to burn fat…which then helps with weight loss.

    If you add exogenous ketones, then your body does not have to bother burning fat because it is getting the “free” ketones without having to consume any fat.

    So, you are likely to lose the weight loss benefits, according to some “negative” articles I have read.

    Correct, or not?

    Also, what evidence is there that these supplements put you back into Ketosis for the long term, as opposed to merely enjoying the benefits until the supplement you ingested is burned off?

    1. No this is wrong. Your body will use your own fat and any fat you eat as fuel. This counts as exogenous ketones. It won’t stop burning your fat. The same logic would say that if eating any fat your fat loss would stall and that is not true. It can help get you back into ketosis because you have certain monocarboxylic acid transporters that are upregulated when ketones are present. The evidence is physiology.

  14. I’m already following a ketogenic diet and have been fat adapted for about 3 months. Since I’m already in ketosis would this product help me or hinder my fat loss? My thought is that if I’m already in a fat burning state and then I take exogenous ketones does my body stop burning my fat to burn the ingested ketones like taking a break or does the product enhance the fat burning that is already taking place?

  15. Hi, I still a little confused about when or how to take this. I am trying to get adapted and minimize the flu. Is it most beneficial before eating, after eating, with food or in place of food? I have been keto in the past but this time I am not switching over to fat burning mode even though my macros are good. ( I am thinking it is just too many calories and carbs at this point but I get hungry!) Help please.

  16. Hi. Any reason why I’d feel sleepy about an hour after taking PK? Have taken 3 doses, different days of course, always in the morning while fasting – same result Thx in advance:)

  17. Great post. I was checking continuously this blog and I am impressed! Very useful information specially the last part 🙂 I care for such information much. I was looking for this certain information for a very long time. Thank you and good luck.

  18. Thank you for this informative article. I do have a question I’ve been taking phenibut recently do you know if exogenous ketones cause any problems using them together?

  19. My sister had a colleague try to sell her on exo ketones as basically a way to skip the keto diet part. I told her this is like putting high octane fuel in a mini-van, it’s not meant to by a crutch, but an enhancer. I told her it’s a waste of money to take exo ketos without actually changing her eating habits and lifestyle.

  20. Hi, I started doing intermittent fasting several weeks ago (16 hours fasting, 8 hour window for eating) and do HIIT 3 days a week before breaking my fast. I am also considering doing a keto diet and/or Perfect Keto supplement. With all these combined, is that all too much or is it safe and easy enough to juggle? Does that make sense?

  21. I have a couple of questions:
    1. When is the best time of day to test for blood ketones? (I’m told they need to be between 0.5 and 1.0 mmol/L to be in constant ketosis)
    2. What is the best macro ratios to go with?
    (70% fat/25%protein/6-8% net carbs in a daily caloric range or just under 2000 calories per day) is this too much protein? I can’t seem to get my blood ketones above 0.2-0.3mmol/L
    Or should I be eating (75%fat/17-19% protein/8-10% net carbs in a daily caloric range of 2000-2000 per day)
    my goal is fat loss/muscle strength/endurance and definition increase aesthetically and improve mental and physical energy.

  22. Hi! Trying to get a little clarity. If one has a day or meal with “too many” carbs and takes exogenous ketones to get the body to burn ketones instead of carbs, how does the body handle the carbs?

    I’m not sure whether I am leto-adapted but have been following the keto program for about 6 weeks. The scale and the eye confirm I have been burning fat. I’ve been using ketostix to keep track of ketones as I don’t prefer to prick my fingers to get blood measurements. I have reached my weight loss goal and planning to transition to maintenance in the next couple of weeks. I’m curious if exogenous ketones will be aid in maintaining my weight.

  23. If you eat a meal high in carbs and then drink perfect keto your body is signaled to use the ketones for energy. What happens to all the excessive carbs you’ve eaten? Do they automatically get stored? Can you explain the science behind this?

  24. I am breastfeeding so nees to have some oatmeal in the morning, but eat mostly keto the rest of the day. Can I take this after breakfast to realize the benefits of ketosis for the rest of each day?

  25. Ketones are produced by the body as a indicator of the body starting to use fat for fuel. Your body then uses those ketones as brain fuel (mostly) , but if you were to have a carb meal it would kick your body out of ketosis (fat burning state) because the carbs are a more easily usable source of energy. So why would you want to add a outside source of energy such as ketones not naturally produced by the body its self? It would kick you out of the fat burning state just like the carbohydrate meal because your body rather spare it’s own energy source as much as possible and also since the outside source ketones are not naturally produce by the body your body does not go into fat burning state because it doesn’t have to go through the natural process to produce its own ketones meaning the body is in its fat burning state since ketones are a by product of fat being used as fuel. Your body has to go through the natural process by itself. Outside ketones are treated as a alternative fuel source so your body has no reason to use fat as its fuel source. Just like carbs. Don’t fall for the scam do your homework it’s science backed up by facts. https://www.t-nation.com/diet-fat-loss/avoid-this-ketogenic-rip-off

    1. Dusty you assume only everyone wants fat burning. I think this is silly. The brain and heart will prefer ketones over carbohydrates when both are present in the blood stream. Look at the research and mechanism. I don’t want fat loss, I want better brain function. I also regularly eat carbs myself. This is one of the reasons I myself use exogenous ketones. No this isn’t a magic fat loss powder, but don’t sit here and quote T-nation trying to rebuttal this article acting like that is a credible source.

  26. I’m confused on how to use these products and which ones will benefit me. I started a low carb diet almost two weeks ago for the purpose of losing weight. I’ve lost about six pounds. Will any of these products help me? And if so, how should I take them?

  27. hi im doing intermitent fasting 16 / 8 and as wondering could i take this in the morning with coffee
    would it break my fast.

  28. Great information. And apparently I have found out what my problem is. I got into Keto a few weeks ago. Transitioned into ketosis after a week, and then had to travel….while I followed a keto diet as best I could, (I took your powdered MCT Oil with me and it is great), but I did fall out of ketosis. Now it’s been 2 weeks and I can’t seem to get back into ketosis.
    I heard a rep from Perfect Keto on a podcast and your Exogenous Ketones. I ordered and received it the other day. I see from this article that I should not do a full scoop at once, but break it up in a day. Good to know. I had about a half scoop before I worked out this morning and could tell I had more energy. Loved that. Just curious….any ideas how long it will take me to get back into ketosis and fat burning?? (I know it depends on what I eat, but a general idea that I promise not to hold you too! (I’m actually missing having ‘keto breath!)

    Thanks for any help!!

    1. Hey Staci, great to hear you’re getting back into it! To answer your question, it really depends on the individual but there are definitely things you can do to get back into ketosis faster – working out to deplete your glycogen stores or implementing intermittent fasting into your regimen – these are 2 common ways that should kick start you back in the right direction!

  29. Dr Gustin and Mr Cunningham,
    Hello! I am a 43 yrs old 5’2″ and 215 lbs female with Hashimotos disease. I have tried so many different diets, supplements and weight loss pills over the years with no good long lasting results. I am ready to try this now. Is there hope???

    1. Tera, yes there is always hope!! Keto has been proven time and time again to help people with a variety of different disorders and the research continues to emerge on the many many benefits of keto!

  30. Hi there,

    I am inquiring about getting a quote on your exogenous Perfect Keto product at wholesale pricing. Please include contact information.

    Thank you,
    Katherine
    Active Body Nutrition Okotoks

  31. I have been a low carber for many years. And I’ve experienced all sorts of excellent health benefits plus mental clarity, for sure. I was basically an Atkins follower, but was never able to turn the ketosticks purple. So, I’m not sure if I have ever really been in ketosis.

    I have, though, recently been diagnosed with ovarian cancer. After reading through your blog, I noticed there was a little about Ketogenetic diet and cancer. I purchased the MCT oil powder in hopes that will help me get into ketosis for the purpose of “starving” the cancer cells. Other then focus, I didn’t see any particular format for something like this. Here are my questions: How much of the powder should I take? And do you think the diet plus the MCT oil is a good idea for 1) aiding chemotherapy and 2) helping shrink the number of cancer cells?

  32. Wonderful website you have here but I was curious if you knew of any
    community forums that cover the same topics talked about in this
    article? I’d really love to be a part of community where I can get opinions
    from other knowledgeable individuals that share the same interest.
    If you have any recommendations, please let me know.
    Bless you!

  33. I’m a little confused. I am depleted my body of carbs so that it will burn fat for energy. But if I supply my body with energy (exogenous ketones), my body will use that instead of burning fat.
    It seems like taking the exogenous ketones would be counterproductive. What am I not understanding?
    Thanks.

  34. Appreciating the time and effort you put into your website and in depth information you present. It’s nice to come across a blog every once in a while that isn’t the same outdated rehashed information. Wonderful read! I’ve saved your site and I’m adding your RSS feeds to my Google account.

  35. Hi, I usually put MCT oil and grass fed butter in my morning coffee. Is there a benefit to subbing your Perfect Keto base instead of the MCT oil, besides the decrease in calories? I am looking for sustained energy, and appetite control until lunch. Thank you.

    1. Hi Jodi, yes, our Perfect Keto Base contains exogenous ketones whereas MCT Oil does not and has been shown to aid in sustained energy and appetite control 🙂

  36. I eat one meal a day during a one-hour window and fast 23 or more hours every day. I want to use your ketones to get back into ketosis faster after that meal. Will that work? I am confused, because say at the end of my hour eating window I drink your ketones, sure there are lots of ketones suddenly in my body but I also have a big meal in my stomach. My body has to digest and use that food energy, so how do exogenous ketones help me in that case?

  37. New member here, I am using IF from 7pm until noon each day and have the chocolate salts. I have been taking them in the am on an empty stomach for fat/wt loss – Is this wrong? What is the optimal timing for this? Should I be waiting until after lunch because the Am one is not even needed or taking 2 scoops one in am and one after lunch?

    1. Hey Lisa, if what you’re doing is working for you than I would keep it up! Lots of people take one scoop in the a.m. and one in the p.m. – just depends on your goals and schedule.

  38. Hello, I desire to get rid of stubborn belly fat. I heard about doing some HIIT first thing in the morning helps to go burn the fat since your on a fasted state but there are risk of loosing some muscles aswell so I was wondering if exo ketones would be a good supp to take in the morning before doing HIIT workout. What do you say?

  39. I have bought this and waiting for shipment. I am planning to put a scoop in to make bulletproof hot chocolate in the mornings for my breakfast meal. Would this be an appropriate use regarding timing and mixing? I’m confused whether I should eat anything after mixing this or if adding it for BPHC is enough for breakfast.

    1. Heather, I’d suggest starting with just this and your bulletproof coffee to see how you feel before adding in extra foods. This may fill you up and give you all the energy you need to start the day!

  40. Hi! My question is, how low must my current daily carb count be in order to benefit from taking your exogenous ketones? I am a 33 year old female, keeping total carbs at 100-125 grams per day. My priority is fat loss, and I do HIIT training 4-5 days a week. I’ll soon be adding in heavier strength training. I don’t function well eating less than 100 total carbs a day. Could this even benefit me? And if it will benefit me, would the befits outweigh the sodium content? I keep my sodium at 2,000 mg a day, as I’m trying to avoid water weight.

    I hope to hear from you if you have time!

    1. Hi Shannon, exogenous ketones are just another fuel source for your body. You could definitely benefit especially with a lower-carb intake. Maybe even try using them as a transition into lower carb to see how you feel 🙂

  41. Should I already be in ketosis from a natural low-carb diet when I begin supplementing ketones can I supplement in lieu of restricting carbs?

  42. Hello! I have LADA (latent autoimmune diabetes in adults) and a few other autoimmune illnesses. I want to try a keto version of Paleo, but am worried because of pancreas and kidney problems I already have. Will exogenous ketones or ketones in general cause any organ issues I should be aware of?

  43. Does drinking too much exo ketone products reduce weight loss? I am in ketosis, eat very little carbs and enjoy 2 water bottles of BHB keto products a day. I want to make sure I am not negatively impacting my weight loss for the sustained mental energy I enjoy from drinking it.

  44. I have been in ketosis for 5-6 weeks. I eat less than 20 total carbs a day. I am losing weight, but it’s slow. Does this product have any benefit to me?

    1. Hello Meridith! Here are some of the benefits you can get from exogenous ketones:

      FAT LOSS: Especially in the morning or between meals, ketones boost your body into an effortless fat burning mode.

      PHYSICAL PERFORMANCE: Ketones before and during workouts give you energy and decrease need for oxygen.

      MENTAL FOCUS: Ketones improve energy levels for brain cells, increasing mental output and sharpening focus.

      HEALTHSPAN: Ketones help you get into ketosis for benefits from enhanced well-being, to disease prevention and longevity.

  45. and by the way! the product you’re marketing has way too much salt – it will negate the true, natural process of any keto diet. salt will make you retain water, which is exactly what you don’t want to do, if you ever really want to lose weight! and if higher than normal blood pressure is your goal, enjoy responsibly! in fact, if you lower your overall salt intake, you will shed much more water weight in the first weeks, as mentioned elsewhere.. one of the secret cheats to get you going. drinking plenty of water and frequent urination will keep you properly hydrated – just be aware when testing with urine strips, too much water will give you a lower reading. stay hydrated, stay healthy – have fun losing the weight!

  46. I see the ingredients of the exogenous ketone powder is high Magnesium and Calcium.

    How is this a good thing when Neither of these should be taken together, as Magnesium inhibits Calcium absorption ?

  47. I see the ingredients of the exogenous ketone powder is high Magnesium and Calcium.

    How is this a good thing when Neither of these should be taken together, as Calcium inhibits Magnesium absorption ?

    1. Hi Steve, it is magnesium glycinate and is one of the more bioavailable forms of magnesium. We’ve added calcium for increased absorption.

  48. New to Keto. Which is the best product to start with, having a difficult time determining this. Main goal is weight loss so will be incorporating with current diet and exercise regimen.

    1. Hi Kelly, all of our products are made to help support a keto diet and lifestyle. If your main goal is weight loss I would highly recommend taking our Exogenous Ketones before you do any high-intensity weight training or first thing in the morning on non-training days, and then supplement with our Keto Whey after your resistance training or anytime through the day you’re tempted to snack on something unhealthy and full of empty calories.

  49. I am currently in ketosis (day 40). I am concerned that if I supplement with exogenous ketones, that my body will use these ketones for energy rather than breaking down my won fat into ketones for energy. Can you comment on this? How often do you recommend supplementing with exogenous ketones for maximum fat loss? I work out with weights 2-3 AMs per week.

    1. Hi Jacklyne, exogenous ketones act as an additional energy booster. Since you’re already in ketosis, supplementing with Exogenous ketones can stimulate weight loss by increasing energy and decreasing hunger. You may try supplementing with 1/2 scoop a day and gradually round up your intake.
