Chances are you've heard about collagen supplements or at least seen the buzz around them in your favorite magazine. But what exactly is collagen and what does it do? To put it simply, collagen is the main structural protein of connective tissues such as bone, skin, cartilage, and tendons, and its explosion in the market is due to the hypothesis that if humans ingest it from outside sources, it can support and optimize our health and address physiological needs posed by aging and exercise.
Since collagen makes up 80 percent of our skin, collagen supplements have been regarded as a tool to improve and maintain skin health as well as joint, gastrointestinal, and bone health. Though with so many supplements on the market, it's hard to know what's legit.
Here, we've rounded up some of the best collagen supplements available for purchase online.
Ancient Nutrition’s Multi Collagen Protein offers a diverse blend of collagen types from multiple food sources. Using collagen from beef, chicken, fish, and eggshell membrane, this product is designed to benefit skin, gut, and joint health. Stick to the original Multi Collagen Protein if you're looking for a product with minimal ingredients (there are only four!) and no flavorings or sweeteners. The odorless, tasteless formula can be added to your drink of choice.
Buyers beware of products marketed as vegan collagen! As we've covered, collagen is the main structural protein of different connective tissues—ones that are located in the bodies of most animals and humans. Tissues such as muscle, skin, tendons, and ligaments are the main sites of collagen and plants do not contain these tissues effectively making vegan collagen impossible. What is possible, though, is to supplement the body’s innate ability to produce collagen by taking a plant-based product high in minerals, vitamins, and protein.
Sprout Living’s Pro Collagen protein powder does exactly that—it provides the body with 15 grams of protein as well as powerful collagen-boosting nutrients from organic ingredients such as rose hips, goji berry, pomegranate, coconut milk, and sea buckthorn.
Research investigating collagen's role in hair growth and repair is minimal, however one study found that taking collagen supplements for 3 months modestly increased hair thickness. (For full transparency, it is important to note that this study was funded by the supplement company.)
Nutrafol contains a potent blend of hair nourishing ingredients called Synergen Complex—a proprietary blend of clinically effective ingredients formulated with unique ratios shown to improve hair growth and quality. Some of these nutrients include marine collagen, biotin, keratin, zinc, and vitamin A, among many others. The supplement is a fan-favorite and consumers can opt for one-time 120-capsule supply or monthly subscription which saves you a bit of cash.
Collagen supports the elasticity and structure of skin and overtime, as collagen levels naturally decrease, the skin’s propensity to wrinkle increases. Type I and III collagen are the main forms of collagen in skin and studies show that taking collagen can have a modest positive effect on skin's hydration, elasticity, and volume.
Besha, a German-made product, is a top pick for skin by Consumer Labs Research. The collagen used in Besha is VERISOL, a form of bioactive collagen peptides that have been used in research studies examining collagen’s effect on skin elasticity. Of note, VERISOL is derived from pigs, so if you have dietary restrictions, you may want to pick a collagen derived from fish or cow.
Further Food Marine Collagen is made from skin of wild-caught North Atlantic cod. Further Food does not use harsh enzymes or heat to extract the collagen, keeping all of the beneficial properties intact. The company's marine collagen peptides are made in facilities that are NSF cGMP certified and their product is paleo and keto friendly.
As an added bonus, shoppers can feel good about packaging as the collagen is packaged in 100 percent post-consumer recycled jars and for those wondering does this taste like fish? The answer is a definitive no!
Consumer Labs Research, an independent nutrition product testing company, ranks Healthy Origins UC-II Collagen the best for joint pain and we have to agree. UC-II contains a patented form of intact type II collagen which has been examined in multiple research studies for its efficacy in relieving joint pain.
A randomized, double-blind placebo-controlled study—otherwise known as the gold standard in research—published in The Journal of the International Society of Sports Nutrition tested the use of UC-II in individuals who experienced knee discomfort during exercise. Researchers examined the efficacy of the supplement based on participants’ ability to extend their knees. After 120 days of supplementation, subjects in the UC-II group exhibited a statistically significant improvement in average knee extension compared to placebo. If you struggle with mobility or flexibility, this is a great dietary supplement.
Vital Proteins puts extra care into the sourcing of their bovine collagen peptides. The cows used for the production of their collagen peptides were raised in alignment with the Global Animal Partnership 5-step Animal Welfare Rating standards, an important quality to look for when purchasing protein powders sourced from animal ingredients.
In addition to grass-fed bovine collagen, Vital Proteins adds vitamin C to their powder to increase collagen absorption. Add a dose to your daily smoothie or even your water or coffee—who knew vitamin C consumption could be so easy?
Thrive Market prides itself on using quality ingredients and their chocolate-flavored Collagen Peptides is no exception. This supplement offers collagen from grass-fed and pasture-raised cows and uses organic cacoa powder, organic vanilla flavor, and monk fruit extract to provide a rich, satisfying flavor. Add it to your smoothies, coffee, and overnight oats; in addition to providing a dose of collagen, this powder is a great way to boost meals with 10 grams of protein.
Liquid collagen supplements are hard to come by. Independently tested by Consumer Labs Research, LiquiVive is free of common allergens such as gluten, soy, yeast, and milk and dissolves easily in cool water. Slightly sweet due to the fructose and cherry flavoring, this product is ideal for smoothies or water. Compared to other products, LiquiVive is also a superbly affordable option with each serving costing less than a dollar.
