These Are the 10 Best Collagen Supplements Dietitians Love in 2025

Sourcing and quality are also key strengths of this pick. Derived from grass-fed, pasture-raised cows, this collagen is third-party tested for purity and potency and is certified by the National Sanitation Foundation (NSF) as gluten-free.

Some may find the flavored options less versatile than unflavored ones, which can be mixed into virtually anything without changing the taste or flavor, but this comes down to personal preference. It’s also worth noting that collagen is not a complete protein, so you can’t rely on it entirely for your amino acid or protein needs — but with a balanced diet that includes other protein sources, this isn’t usually a concern. Overall, Garden of Life Grass-Fed Collagen Beauty is a high-quality supplement that combines effective beauty-supporting ingredients with a pleasant, tasty flavor.

We selected NOW BioCell Collagen Hydrolyzed Type II as the best option for joint health due to its comprehensive joint-supporting formula. “NOW BioCell Collagen combines hydrolyzed collagen type II, chondroitin sulfate, and hyaluronic acid for a complete collagen supplement to support joint health,” says Amy Brownstein, MS, RDN, plant-based dietitian and owner of Nutrition Digested in the San Francisco Bay Area.

For those who are looking for real-world results, Danielle VenHuizen, MS, RDN, a Seattle-based dietitian and owner of Food Sense Nutrition, shares her personal experience with the capsules, saying, “I can say I’ve been taking this as directed for just a week and am already noticing improvements in my creaky knees and moisture levels in my skin.”

For those interested in taking proactive steps to protect their joints, NOW BioCell Collagen Hydrolyzed Type II is a top choice. Keep in mind, the full dose requires four capsules daily, which may not appeal to everyone.

“Beyond its impressive collagen profile, this product stands out for its clean formulation, which is non-GMO, free of artificial sweeteners, flavors, and preservatives, and third-party tested for quality,” says Ballenthin. The powder contains 18 amino acids and is unique as it includes multiple collagen sources from organic chicken, grass-fed beef, and wild-caught fish.

Ballenthin likes that her clients can easily mix this powder into water, coffee, tea, or any favorite bev[erage for a protein boost. “A fun way to incorporate collagen can be adding a scoop to matcha powder with your milk of choice and a half tsp of maple syrup,” she says.

A minor downside is that this specific product only comes in an unflavored version (although Codeage has other types of flavored collagen options, such as chocolate and mocha, on its website). Otherwise, we love that this powder delivers a multi-collagen formula you can feel good about.

People with busy lifestyles will find the portable single-serving sachets easy to use on the go. “Plus, it tastes good, which helps a lot with daily habits,” says Simpson. Though it only offers one flavor and is pricey compared to many on our list, Vida Glow Collagen Liquid Advance distinguishes itself through its combination of high-quality ingredients and convenience.

We like the bright, fruity flavor, making incorporating them into a daily routine easy. The product is also free from artificial sweeteners and unnecessary additives. Plus, all Vital Proteins products are made in an NSF-certified CGMP (Current Good Manufacturing Practices) facility. “They’re clean, taste good, and make it easy to be consistent,” says Simpson.

A downside for some is that this product contains 5 g of sugar, which should be taken into consideration if following a low-sugar or low-carbohydrate diet. Overall, the research-backed formulation makes Vital Proteins Collagen Gummies a solid choice for an easy, mess-free, tasty collagen supplement.

If you want your collagen to taste like a treat, the chocolate-flavored Vital Proteins Collagen Peptides is our top pick among flavored options. “Naturally flavored with cocoa powder and stevia, it has a smooth, rich chocolate taste without added sugars, making it highly palatable for those who might otherwise skip unflavored supplements,” says Kirbie Daily, MS, RDN, LDN, assistant director of sports nutrition for the University of Memphis.

This supplement is also third-party tested and NSF Certified for Sport, ensuring it meets strict third-party safety standards. “Vital Proteins products are manufactured with high-quality standards and transparency, offering confidence for use in collegiate and recreational athletes and providing peace of mind,” says Daily.

She also highlights the product’s versatility. “Its ability to seamlessly blend into post-practice shakes, recovery snacks, or even morning coffee makes it incredibly practical,” she says. Daily adds that it’s ideal for recovery and joint health in a way that encourages consistent use. “From a performance-nutrition perspective, compliance and consistency are everything. This product hits the sweet spot by offering a delicious, easy-to-use collagen supplement that athletes will actually enjoy and remember to use daily.”

Each serving provides 20 g of collagen peptides to support healthy joints, skin elasticity, and overall recovery. It can easily be added to smoothies, yogurt, and oatmeal along with coffee. However, the serving size of 4 tbsp is larger than many comparable powders, which Daily acknowledges can make the mixed product slightly thicker than some might prefer. Overall, Vital Proteins Collagen Peptides is a top choice for anyone looking for a sweet, tasty way to add more collagen to their routine.

Our top pick for athletes who want a clean and effective collagen supplement to support recovery is Klean Athlete Klean Collagen+C. “When recommending supplements to athletes, efficacy, safety, and simplicity are nonnegotiables,” says Daily. “Klean Athlete Collagen+C nails all three of the categories.“

While the premium pricing could be a potential downside for some users, Klean Athlete Klean Collagen+C checks all the right boxes for an athlete-focused collagen product.

For those seeking a collagen supplement that prioritizes purity and skin benefits, Vital Proteins Marine Collagen stands out as a top choice. “Just 3 tbsp daily provides 12 g of collagen, all coming from cod,” says VenHuizen. This simplicity, combined with its effectiveness, sets it apart in the marine-based category.

VenHuizen also highlights its versatility in her daily routines: “It blends seamlessly into my coffee; no clumps or weird taste,” she says. With no added fillers, flavors, or sweeteners, it provides only what you need to support skin, hair, nails, and joint health.

Those with fish allergies should avoid this product. We also noted multiple users mentioning recent changes to the container, with some finding it harder to open. That said, Vital Proteins Marine Collagen is still an excellent choice for those looking to reap the benefits of fish-derived collagen.

Needed. Collagen Protein is our top choice for those who want a collagen supplement specifically crafted to meet the unique needs of pregnancy and postpartum. “Expectant or breastfeeding moms can add this to their diet with peace of mind knowing it contains no artificial additives, sweeteners, or fillers, and it’s third-party tested for heavy metals and contaminants,” says Berger. “The formula has a smart design because it doesn’t include added vitamins or minerals, so it won’t conflict with your prenatal vitamins.”

Remember that while collagen adds more protein to your diet, it’s not a complete protein, so you’ll need to rely on other protein sources to meet your daily needs. It’s also always essential to consult your doctor before adding any supplement during pregnancy. However, this product’s quality ingredients and thoughtful design make it a trusted option to support skin, joint, and prenatal health.

For a grass-fed option that supports overall wellness and athletic performance, our top pick is Further Food Grass-Fed Collagen Peptides. Sourced from grass-fed, pasture-raised bovine collagen, this powder contains high-quality ingredients while supporting sustainability. “Further Food Grass-Fed Collagen Peptides stands out because it offers highly bioavailable collagen with minimal ingredients,” says Daily

From easy-to-mix unflavored to unique flavor options like matcha, pumpkin spice, chocolate, and lemon, Daily says you can add Further Food Grass-Fed Collagen Peptides to smoothies, coffee, oatmeal, or even soups. “It’s free from sugar, artificial sweeteners, gluten, dairy, and soy, making it allergy-friendly,” she adds.

“I also appreciate that Further Food truly values having nutrition experts like registered dietitians who understand the importance of maintaining supplement integrity and providing credible education on the product itself,” says Daily.
