The Best Collagen Peptide Protein Powder

We put so much care into creating our products and sourcing our ingredients, we can’t help but cheer when others take notice.

Our friends over at The Unwinder know quality when they see it. Check out their recent article on the best collagen protein powders on the market, and see why they ranked Promix’s Unflavored Collagen Peptides as the absolute best you can buy for types I & III natural collagen protein (1).

(Take a deeper dive with us into the different types of collagen we have to offer and learn why it’s the MVP of natural protein powders.)

With one, high quality ingredient, our signature natural collagen peptides deliver 20 grams of pure protein per serving with no fat or carbohydrates, and offer up benefits for gut health, and hair, skin and nail strength (2).


“No doubt, with only one ingredient: 100% percent collagen made from a grass-fed bovine protein, Promix takes the cake. As bioavailable as it is flavorless (read: very), this collagen supplement will pack a protein-punch (20 grams per serving) to your smoothies, teas, and cakes—without ruining the taste.”

-The Unwinder

Their assessment is accurate: our athletes find that our Unflavored Collagen Peptides are their go-to protein for smoothies, coffee & tea, and even a staple when adding extra protein into baked goods.

(Unflavored Collagen Peptides are definitely on our elite runner’s list of “What to Eat Before Running.”)

The Unwinder goes out of their way to shout out our convenient single serving stick packs, available in 30-pack boxes.
