The Best 14 Collagen Powders, Tested and Recommended by Dietitians

We found the taste neutral and mixed best in hot liquids, but you could also add it to smoothies. We wouldn’t recommend using it in cold liquids without an electric whisk. Overall, Garden of Life offers a quality option if you’re looking for a comprehensive product to support gut health and immunity.

Beyond the price, Codeage stands out for its formulation. It’s non-GMO, gluten-free, dairy-free, soy-free, shellfish-free, third party–tested, and certified by the National Science Foundation (NSF), and the unflavored powder blended smoothly into drinks in our testing without clumping.

Rather than disappearing into any beverage like an unflavored powder, this chocolate option is better suited to coffee, smoothies, or recipes where its cocoa-forward taste can shine. And, like other bovine-derived (cow) collagen products, it is not suitable for vegans or vegetarians.

Vital Proteins Chocolate Collagen Peptides is “one of the best collagen supplements on the market,” says Phoenix-based Nicole Ibarra, RD. “It’s tested by a third party to ensure it meets strict quality standards and is also certified by the NSF.” We also gave it the edge on value: Compared with Bulletproof’s chocolate collagen, Vital Proteins delivers the same 20 g of collagen per serving at a lower cost per serving and per gram of collagen, making it the more budget-friendly chocolate option.

While 1st Phorm Collagen is quite sweet, which may not suit all tastes, it blends well in hot and cold liquids. It does contain sucralose, an artificial sweetener that some people may prefer to avoid. However, if you’re looking for a flavored collagen with a bit more sweetness, 1st Phorm has you covered.

Sports Research Collagen Peptides offers vanilla collagen at an affordable price of just over $1 per serving. This product contains 11 g of hydrolyzed type I and III collagen peptides per scoop. This product is NSF-certified, available in multiple flavors (not only vanilla), and certified gluten-free. We like its neutral flavor and the fact that it easily mixes into hot beverages like coffee without altering the taste or texture. It also performs well in smoothies, adding beneficial protein without overpowering other ingredients.

It’s worth noting that this product doesn’t mix as well in cold liquids, leaving a thin white film on the top and a mild, milky flavor.

Many of the collagen options on our list would work during pregnancy, but we selected Needed Prenatal Collagen Plus for its exceptional quality standards and dedicated focus on supporting pregnancy and postpartum needs. “Needed Prenatal Collagen is third party–tested, using only grass-fed bovine collagen with no additives, highlighting their commitment to simple and high-quality ingredients,” shares Kaytee Hadley, RDN, functional medicine dietitian and founder of the Integrative Center in Richmond, Virginia.

Hadley cautions that supplementing with any product during pregnancy should warrant a conversation with your doctor, as there is limited research specifically on collagen supplementation during pregnancy. Once you get the okay from your doctor, Needed Prenatal Collagen Protein is a standout option for pregnant individuals seeking safe and effective collagen supplementation.

FullWell’s Unflavored Collagen Peptides Powder balances high-quality sourcing with an accessible price point. This powder is derived from 100 percent grass-fed, pasture-raised bovine and comes from a dietitian-founded brand. Each serving provides 15 g of types I and III collagen and dissolves smoothly in both hot and cold liquids, leaving no gritty residue or clumping, making it easy to work into a daily routine.

We also like that FullWell’s collagen is third party–tested for ingredient accuracy, heavy metals, and the top eight allergens (milk, egg, shellfish, fish, tree nuts, peanuts, wheat, and soy), which adds an extra layer of reassurance during pregnancy. The main drawback is the packaging, which we found could cause spills when first opening.

This product is third party–tested and NSF Certified for Sport, guaranteeing it’s free of harmful ingredients and meets the strict safety standards required for athletic use. It mixes well into beverages (although we noted it takes slightly longer to dissolve in hot liquids). The unflavored option is a good choice for those who prefer not to alter the taste of their drinks, but the berry flavor also provides an alternative for those seeking a touch of sweetness.

It’s important to note that Klean Collagen+C contains bovine-derived collagen, which makes it unsuitable for vegans or vegetarians. We also noticed it took longer to dissolve in hot liquids than some of the other options. Otherwise, if you’re an athlete and want to boost collagen synthesis with a high-quality, scientifically supported supplement, Klean Collagen+C is a reliable option.

The formula is made of grass-fed, pasture-raised hydrolyzed collagen peptides with types I and III collagen. It’s also third party–tested, gluten-free, dairy-free, soy-free, and non-GMO.

While Thorne Collagen Plus is undeniably high in quality, its complex formula reflects a higher price point compared with more basic collagen powders. Still, the unique and potent ingredients may justify this premium cost.

Beam Collagen is third party–tested and formulated without dairy, artificial sweeteners, synthetic colors, or fillers. This combination of added beauty-focused ingredients and a more accessible price point help it stand out as a strong value option for anyone shopping for collagen with skin support in mind.
