With health benefits like improved bone mineral density, the appearance of fine lines and wrinkles, and decreased joint pain, it makes sense that collagen is taking off[*][*][*].

While, on the one hand, this creates a variety of options for you to choose from, it can also create a bit of confusion as to which collagen is right for you.

In this article, you’ll learn:

What Are Collagen Peptides?

Collagen is a protein that makes up the greater portion of your connective tissue. It’s the most abundant protein in your body, and it provides structure and function to your bones, skin, ligaments, and tendons[*]. 

As you age, collagen production naturally starts to decline. This is why you may start to see more wrinkles on your face, your joints may become weaker, and your bones become more fragile. 

Collagen supplements come in to support your body against its natural decline in collagen. With that being said, not all collagen supplements are created equal. 

Collagen peptides are a type of collagen that’s gone through the process of hydrolysis. 

Hydrolysis involves adding water to break down the protein into smaller molecules called amino acids. In this form, the collagen is easier to digest, and therefore has a superior bioavailability than non-hydrolyzed collagen[*][*].  

On a nutrition label, collagen peptides may be listed as either “hydrolyzed collagen” or “collagen peptides.” 

How To Use Collagen Peptides On Keto

Collagen peptides are an excellent addition to any diet, but they work particularly well with keto due to their macronutrient ratio, which is high protein and low carb. 

Some of the most popular ways to use collagen include:

Breakfast

Add it to your breakfast as a morning boost in protein. You can stir a scoop of collagen into your keto oatmeal, add it to your morning smoothie with a green powder and some whey protein, or mix it into your coffee with some MCTs for a delicious nutrient-rich pick-me-up. 

Pre or Post Workout

Protein is crucial for muscle growth and maintenance; that’s why most pre and post-workout beverages are packed with protein. You can simply add collagen powder to water, shake it up after a workout, or make a smoothie out of it with some low-carb fruit options and green veggies like kale and spinach. 

Adding collagen peptides to your post-workout is especially beneficial due to the high bioavailability. After exercise, your body is ready to absorb and assimilate the nutrients you give it, so optimizing your collagen intake during this time is an excellent idea. 

Baked Goods

Maybe you’re not a smoothie person, or you don’t want to add anything to your morning coffee, no problem. You can add collagen powder to any number of keto-friendly baked goods. If you have some collagen in a chocolate flavor, add it to some chocolate keto cookies. Strawberry collagen can be added to delicious strawberry cream cheese fat bombs.

For true versatility, you can add plain collagen to almost any recipe as it has a very mild flavor and mixes easily with the other dry ingredients. Pancakes, muffins, waffles, if you can mix it in, you can add collagen to almost anything. 

Soups and Sauces

Plain collagen, with its mild flavor, can also be added to pretty much any liquid medium. While shakes and smoothies tend to be the most common way to add collagen to a meal, you can’t forget about soups and sauces. 

Add collagen to your homemade or store-bought salad dressing, keto-friendly condiments, soups, or stews. It not only boosts the protein content of your meals, but it will add a little natural thickener as well.  

What Makes Collagen Keto-Friendly? 

Pure collagen is keto-friendly by nature as it’s virtually devoid of carbs and rich in protein. With that being said, many companies formulate their collagen with added ingredients that up the carb count or undermine the purity of the product. 

For instance, some companies will add sugar and flavors that increase the carb count in an effort to make it more tasty. As mentioned, collagen has a pretty mild flavor on its own, so it can pick up different flavors quite easily. Unfortunately, this often means that the collagen powder is no longer keto-friendly.

Another factor to take into account when looking for keto-friendly collagen is the fat content. On its own, collagen does not contain much fat. However, you may notice that some companies add ingredients to the powder to increase the fat content. 

One of the best examples is the addition of MCTs (medium-chain triglycerides), which provide an excellent source of fat for keto dieters. MCTs are readily absorbed and then broken down into ketones, providing a boost of energy along with your easily digestible protein[*]. 

Therefore, the best keto collagen supplements will be sugar-free, with high-quality collagen, and ideally an added source of fat to help you stay in ketosis. 

The 4 Best Collagen Peptide Supplements For Keto Dieters

1. Perfect Keto Collagen Protein Powder

Perfect Keto Collagen Powder is tailor-made for the keto diet. 

Each serving of Perfect Keto Collagen Powder contains 10 grams of collagen protein and 5,000 mg of MCT oil powder. The MCTs give you an extra boost in fat, while the collagen supplies highly bioavailable protein. The collagen is also sourced from 100% grass-fed bovine, which is not only the highest quality of collagen out there, but it’s also the most well-researched. 

The flavoring in Perfect Keto Collagen Powder comes from natural flavors, stevia, and sea salt — absolutely no added sugars or artificial sweeteners. 

Highlights:  

  • Hydrolyzed for enhanced bioavailability
  • Zero added sugar (only 2 to 3 grams of carbs per serving)

  • Paleo-friendly
  • Gluten-free and dairy-free

2. Great Lakes Collagen Hydrolysate

Great Lakes Collagen is one of the original collagen companies offering a powdered format. If you’re looking for pure collagen and nothing more, Great Lakes contains one ingredient only — grass-fed collagen. 

Although you won’t get all the bells and whistles of some other collagen supplements, Great Lakes offers high-quality bovine collagen that’s nearly tasteless, odorless, and dissolves easily in any liquid medium. 

Highlights:

  • 100% grass-fed bovine

3. Vital Proteins Collagen Peptides

Vital Proteins offers bovine collagen with added hyaluronic acid and vitamin C for enhanced bioavailability and collagen production. Hyaluronic acid plays an important role in the hydration and lubrication of your connective tissue, while vitamin C is essential for the production of collagen[*][*]. 

Their original formula is paleo-friendly, Whole 30 Approved and contains no added sugars or artificial sweeteners.

  • Added vitamin C and hyaluronic acid
  • Paleo-friendly and Whole 30 Approved
  • Bovine collagen

4. Primal Kitchen Collagen Fuel

Primal Kitchen’s collagen comes in several different flavors, all sourced from bovine collagen. The Chocolate, Vanilla Coconut, Peanut Butter, and Golden Turmeric flavors include coconut milk powder that gives you a little extra fat, and the unflavored option is made with 100% collagen peptides. 

Sweetened only with monk fruit, the carb count stays at 2 grams per serving, with natural sources of flavor like cocoa powder, cinnamon, vanilla extract, and peanut flour. 

Highlights:

  • No added sugars or artificial sweeteners
  • Certified paleo-friendly, primal-friendly, and keto-friendly 
  • Bovine collagen
  • Added ingredients to boost the fat content

The Takeaway

On a ketogenic diet, it’s not just about the quality of the collagen you’re supplementing with but also the other ingredients that are added to the formula. 

Ideally, your collagen will come from beef (bovine) and will also be 100% grass-fed. Furthermore, there won’t be any sneaky carbohydrate sources like added sugar or sweetened flavorings. 

And if you can find a supplement with fat added, that’s even better. MCTs offer an excellent source of fat that enhances ketone production and provides a boost in energy.
