4 Best Keto Collagen Powders for 2024

Collagen is the most abundant protein in your body. Found in your skin, joints, muscles, and bones, collagen provides health benefits ranging from better skin elasticity to reduced joint pain to improved body composition (1)(2).

Taking collagen orally, whether through food or supplementation, can help you enjoy these benefits, especially since different factors deplete collagen — such as aging, chronic exposure to UV irradiation, a high-sugar diet, and stress (3)(4)(5)(6).

In this article, we’ll explore the best keto collagen powder options if you’re on a low-carb diet.

How to Take Keto Collagen Powder

There are many ways to reap the benefits of keto collagen powder:

  • You can take it in the morning by blending it into your coffee if you would rather have a satiating drink instead of a full breakfast. You could even add a tablespoon of MCT oil — or use a collagen powder with MCTs like Perfect Keto collagen for a boost in ketones.
  • Blend unflavored collagen powder into your smoothie or make an iced chocolatey or fruity drink out of flavored collagen. Some people might even add other keto-friendly ingredients so that their collagen drink becomes more delicious or for the purpose of meeting their nutritional needs.
  • If you love cooking and baking, then find opportunities to mix a serving of collagen powder into soups, sauces, muffins, cookies, and brownies.


Supplementing collagen in your keto diet is a helpful strategy to look and feel your best. Collagen is found throughout your body, which is why taking it in the form of a powder (on top of eating collagen-rich foods) can improve your skin, hair, nails, joints, and gut health among other benefits.

The list we shared features the best keto collagen powder products currently available. Make sure to choose the one that is in line with your goals, has the flavors you prefer (or unflavored if you like it plain), and contains ample amounts of protein per serving.

While collagen supplements are beneficial, keep in mind that they should not be used to replace whole foods.
