The 10 Best Collagen Supplements of 2024, According to Registered Dietitians

Made from high-quality, grass-fed, pasture-raised bovine sources, this popular collagen supplement is versatile and convenient and delivers 20 grams of collagen per serving. Our registered dietitians love the unflavored option and say that it easily mixes into both hot and cold liquids. We've tested it in smoothies, coffee and even baked goods and it doesn't change the taste or texture significantly. You can even purchase single-serving packets for on-the-go.

Our pros also appreciate that this powder is third-party tested and is NSF Certified for Sport, meaning that the product has been thoroughly assessed for quality, safety and purity. Plus, these collagen peptides are small, making them better absorbed by the body. This collagen contains Type I and III collagen, best to support hair, skin and nails.

We're also fans of the brand's advanced collagen formula, which adds in a dose of vitamin C and hyaluronic acid. We know that vitamin C can help support collagen production in the body, and hyaluronic acid may improve skin hydration and joint mobility.

A multi-source formula, this powder from Ancient Nutrition utilizes 10 types of collagen from four different sources to cover all your bases. Ancient Nutrition says that the hydrolyzed bovine hide collagen peptides are pasture-raised and grass-fed in South America and that the hydrolyzed fish collagen peptides come from sustainably wild-caught haddock, cod and pollock from North American waters.

This blend also contains a hefty dose of vitamin C in a special form that is easier for the body to absorb and retain. On top of that, this supplement offers up 2 billion CFU of a special probiotic strain called Bacillus coagulans to support a healthy gut. Our dietitians also appreciate that the brand publishes their Certificate of Analysis readily available on the site, which is a document that shows you everything that's in the product and what's not. Plus, their finished products are tested for heavy metals including lead, cadmium, arsenic and mercury.

We found in our tests that this powder dissolves well in all different types of liquids. However, the unflavored does have a bit of slight fishy odor likely because this collagen comes from so many sources. That being said, it is not a strong smell but noticeable compared to other powders we tried, but luckily this did not impact the taste. The brand also makes the powder in a few different flavors like chocolate, cold brew and more.

Designed specifically for athletes, these collagen peptides from Momentous contain bovine collagen, vitamin C and FORTIGEL, which is a hydrolyzed form of collagen. The brand also cites research that suggests that collagen peptides may play a role in muscle recovery, strength and joint functionality.

Serious athletes will also appreciate that this supplement is both NSF Certified for Sport and also Informed Sport Certified, meaning it has been extensively tested for purity and potency and does not contain any of the substances banned by the major athletic organizations. Momentous even provides recommendations on when to take the powder — on rest days, they recommend taking it 2 to 3 hours post-caffeine consumption, and on training days to take it 30 to 60 minutes before exercise.

We noticed that it dissolved well in hot liquids but had some issues in colder beverages, though it worked great in smoothies. There is no noticeable taste but if you prefer not to take it in powdered form, the brand also makes a collagen shot that can be easy to drink on-the-go.

If you don't eat meat or meat-derived products, most collagen won't be suitable for your lifestyle since it is made from bovine. But some collagen is now available from marine sources, like this pick from Sports Research. Available in unflavored or dark chocolate, this marine collagen contains hydrolyzed types I and III with 18 amino acids.

We found that this marine collagen was easy to take, had no fishy aftertaste and even dissolved well in hot and cold beverages. It had a bit of a smell but this did not impact the taste. The product is third-party tested for quality and you can view the Certificate Analysis and third-party testing of every product you purchase from Sports Research on their website to verify that what is on the label is exactly what is in the container.

You may be familiar with collagen in powder form, but if you prefer to just add a pill to your supplement routine, this choice from HUM comes in a capsule form. The base is a mix of types I and III collagen from grass-fed and pasture-raised bovine, complimented by a dose of vitamin C and then a blend of hyaluronic acid, red wine extract, grape seed extract and chondroitin sulfate to support healthy skin.

This supplement was formulated by a team of registered dietitians and has been third-party validated for purity and quality by the Clean Label Project. In general, all of HUM's products are tested by a third-party for purity, strength, composition and contaminants. Our pros also appreciate that this pick has no artificial colors, sweeteners, flavors or preservatives. But take note that a serving requires three capsules.

If you want to avoid adding a powder or capsule to your supplement regimen, these easy-to-take gummies from Olly may be the perfect way to get your collagen fix. Not only do they have a delicious peach flavor, but you can take a two gummy serving on its own without additional food or water.

Free from synthetic colors, these gummies only have one gram of sugar per serving and get their coloring from lycopene (an antioxidant that gives tomatoes their beautiful color) and paprika. Plus, the supplement is NSF Contents Certified so you know that what is on the label is actually present in the container.

The collagen in these gummies has also been clinically studied to improve skin health including skin elasticity and reducing the appearance of wrinkles in as little as four weeks. But keep in mind that there are only 15 servings per container.

Designed to combat age-related collagen loss, each packet of this liquid collagen from Youtheory supplies 5,000 milligrams of hydrolyzed collagen. It has a balanced berry flavor and uses a hint of stevia leaf extract for sweetness.

Youtheory does not specify the type of collagen in this blend, but utilizes collagen peptides from bovine sources and says that the blend is aimed specifically at improving skin, hair and nail health. There are only 12 packets per container, and the single-serve option can feel a bit wasteful, but it was one of the best liquid collagen supplements we tested in terms of taste and performance and was really convenient to take with you on-the-go.

The brand has high quality control standards and they manufacture every product in-house in their GMP-certified facility. They also claim to test every product beyond industry standards and implement third-party testing for heavy metals and pesticide residue.

Collagen is an abundant protein in the body that provides structure and support to muscles, bones, connective tissues and more. There are different types of collagen (we detail those later on), but type II collagen has shown promise with joint health in patients with osteoarthritis. In fact, research suggests that undenatured type II collagen may be even more effective than glucosamine or chondroitin sulfate supplementation for joint health.

One of our favorite joint health supplements, this pick from Life Extension is formulated with undenatured type II collagen, glucosamine, boswellia and boron, all to promote healthy bones and joints. Plus, this choice passed strict tests as part of ConsumerLab.com's voluntary Quality Certification Program, and Life Extension has high quality control standards too. But the capsules are on the larger side, so keep this in mind.

Most collagen supplements are missing tryptophan, which is an essential amino acid not made by the body. But our registered dietitians like that Neotein collagen is fortified with the correct ratio of tryptophan to make it a complete protein source. Flavors include lemon lime and the new cherry passionfruit, which come in convenient single-serve packets.

What also makes this product unique is that it contains electrolytes. Since many people take a protein supplement and an electrolyte supplement at the same time, this involves drinking a lot of liquid. But this all-in-one protein and electrolyte powder gives you both in an efficient form.

Each packet from Neotein provides a solid 10 grams of protein and 140 milligrams of sodium, all with no carbs or sugars. We also appreciate that this supplement is Informed Sport Certified, which means it has been tested for purity and meets strict quality standards, but it is one of the more expensive price per servings we have seen.

Meeting your nutritional needs during pregnancy and postpartum can be a challenge. If deemed appropriate by your healthcare provider, you may consider taking a collagen supplement during pregnancy to support healthy joints, skin elasticity, postpartum hair and more. This pick from Needed is specifically designed for the prenatal and postnatal period. It features high-quality collagen sourced from grass-fed, pasture-raised, hormone-free bovine. Just one scoop delivers 14 grams of protein as well which can be easily mixed into oatmeal and yogurt, and blended into smoothies. We found it did well in warm liquids, but had some difficulty with clumping in colder beverages.

Needed's collagen protein is manufactured in the U.S. at a FDA, GMP and QAI Certified Organic facility. Every batch is tested for quality and performance, including third-party testing for nutrient content, pesticides and herbicides, heavy metals, microbes, allergens and other contaminants.
