There is a flood of collagen supplements on the market—thanks in large part to their purported full-body benefits.* And with so many options available, you may be struck with a bout of decision fatigue—or be tempted to grab whatever reasonable-looking jar you find at your local health shop. But not so fast: There is actually a method for determining your best collagen fit, and it comes down to your goals and needs. 

See, collagen formulas vary quite a bit—be it due to collagen type or additional ingredients—and these factors play a role in how effective it will be toward an intended outcome. Here, our best bets.

While we've vetted the above products and can recommend them wholeheartedly, we also want to give you the tools to look for your own collagen supplements—or at least help you understand our process.

There is no official daily recommendation for collagen supplementation. For healthy adults, the recommendation for overall protein needs is about 1 gram of protein per kilogram of body weight per day. If you're physically active, your needs may be higher. Collagen is a protein made of peptides, but it's not a complete protein—it doesn't have all nine of the essential amino acids (it's missing tryptophan and is on the lower side on a few others)—but can contribute to your overall protein goals.* For a collagen supplement, we recommend looking in the 10- to 20-gram range. 

Look for brands that describe in detail where their collagen is sourced from, be it on the packaging or website. Look for keywords like "grass-fed, pasture-raised bovine collagen," or "sustainably, wild-caught cod." Ideally, they'll note what collagen types (type I, II, or III) as well. Bonus points if they list the amino acid profile. If your diet allows, we prefer grass-fed bovine collagen, which you can learn more about here.

Powders are the best, as they are able to deliver the most potent amount of collagen. Powders are also a convenient way to add a meaningful dose of collagen to your nutrition routine, whether blending into a sweet smoothie with colorful fruits or mixed into your morning coffee or latte. If you prefer other delivery methods—drinks, tonics, capsules, gummies—that's fine; just know that you're likely not getting as much collagen in these products. 

If there are added ingredients—such as additional vitamins and minerals or botanical bioactives—they can help create a more holistic product to achieve your desired effects (or if you want just collagen, that's great too!).* Look for research backing up why the ingredients were added and thoughtful explanations of the overall formulas. On the other end, make sure the formula is clean. Less is more here: Skip artificial colors, flavors, gluten, GMOs, soy, gluten, and known allergens. If your collagen product has flavors, look for natural varieties (such as organic cocoa, organic vanilla). If there's a sweetener, we recommend things like organic monk fruit extract or organic coconut sugar.

This is less about decoding an ingredient label and more about finding brands that are open and honest about their product. If they make any benefit claims, there should be science to support them. They should be open about where the ingredients come from, and they should explain the packaging it comes in (i.e., is it environmentally friendly?).

Finding your perfect collagen fit really boils down to figuring out what your goals and priorities are. Once you narrow down the why, then you can start looking into the what. But we went ahead and made the latter part easy for you—these 16 options are the best out there.
