I love Perfect Keto in our Rocket Fuel Latte’s or even just plain water. Perfect Keto is my favorite supplement because there are never any artificial or scary ingredients. It’s only what you need for great keto energy and recovery, and nothing extra.

Why Fusion Lean recommends Perfect Keto

Get back into ketosis

If you’re eating low carb or keto-adapting, you might feel lousy and irritable. That’s the keto flu kicking in, and your body starting to metabolize fat instead of carbs. It hasn’t quite adapted to your new source of energy. 

Perfect Keto Base gives you exogenous ketones to raise your ketone levels, quickly and effectively — giving you a clean energy boost to get your body past the keto flu.

Go keto and feel great in the process.

Keto burns fat

You want to lose weight. Low-carb diets like keto help you lose weight better than low-calorie diets. 

We give you the delicious keto supplements that make it super easy to start. They’re doctor-created, so you can trust what you eat.

Not bitter

BHB ketones taste notoriously awful. Until Perfect Keto, you’d have to force yourself to eat them. Stop wasting your willpower on bitter keto powders with fake ingredients, and save it for the important moments.

Perfect Keto Base comes in four delicious, zero-filler flavors to get you the ketone boost you need. They taste great in water AND make a great addition to keto recipes.

Enjoy going keto. There’s no need to compromise.

Ketosis leads to focus

Overwhelming days can be rough.

But keeping great mental clarity isn’t so hard.

When you’re in ketosis, your brain utilizes fat — a more consistent form of energy than the carb rollercoaster. So you can focus better. Naturally.

These results suggest that chronic ketosis with the ketogenic diet increases the contents of ATP in the brain and this increase in ATP probably accounts for the neuronal stability.

Ketosis leads to more energy

You got a full nights sleep but you still feel like you’re in a food coma. 

Perfect Keto Base boosts your energy and ketone levels for peak performance while you work and exercise.

Running on ketones is how you avoid sugar crashes and food comas. Without fillers or garbage ingredients.

The energetic consequences of oxidising ketones may significantly enhance athletic performance.

We’ve had the opportunity to try dozens of different high-end supplements, but nothing seems to come close to the quality of Perfect Keto. I absolutely love their Keto Collagen and MCT powder, and use them in my coffee every morning to kickstart my mind and fuel my performance. And for this price, Perfect Keto just can’t be beat.

Perfect Keto solves all my problems. It tastes incredible and allows me to rest easy knowing I'm set on micronutrients and macronutrients. I don't go a day without Perfect Keto!
