Collagen supplements have flooded shelves of grocery and health-food stores—and if you’ve been confused by which to try and trust, you’re not alone. Even if you have Superman vision that can see through clever marketing and convincing promises, the sheer amount of collagen products out there can muddy your normally astute and discriminating decision-making. We did the due diligence to provide you peace of mind and separate the truly good from the copycats.
What are Collagen Supplements?
Simply put, collagen is a type of protein found in your body. It’s important for skin and bone health, among other functions. Collagen supplements come from animal sources, each of which bestows different benefits, and there are different types of collagen, Type I, II and II. You can read more about which collagen types are best for you here. Supplements most commonly come in powdered form and can be mixed into drinks such as coffee and smoothies.
If you’re a vegan or a vegetarian, collagen may not be an option because it’s obviously an animal product, but that doesn’t mean you can’t enjoy the beauty benefits. Our collagen guide for vegans and vegetarians shows you how you can boost collagen production on a plant-based diet.
Collagen Supplement Regulations
The Food and Drug Administration (FDA) considers collagen a dietary supplement—and the safety and effectiveness of dietary supplements are not regulated by the FDA. In other words, it’s up to the manufacturer to make sure their products are safe.
The rules for marketing dietary supplements are fairly strict. Companies can make some general health claims about their products, but they must also print the disclaimer: “This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease.” The FDA keeps tabs on supplements and how they’re marketed, taking legal action against those who make false claims or whose products are unsafe.
When choosing any type of supplement, it’s crucial that the manufacturer hasn’t been reprimanded by the FDA for any of these violations.
The Health Benefits of Collagen Supplements
Before adding any type of supplement to your diet, it’s important to talk to a qualified health pratictioner. In the meantime, here’s what the current research has to say about the benefits of taking collagen.
Many people take collagen for joint pain, especially pain associated with arthritis. A 2006 review of clinical research on collagen and joint pain stated: “A growing body of evidence provides a rationale for the use of collagen hydrolysate for patients with OA [osteoarthritis].” Another study on taking oral collagen was done on athletes at Penn State University. While taking a collagen supplement for 24 weeks, the athletes reported less joint pain. While these results are promising, more research is needed to provide conclusive evidence of the benefits of collagen for joint pain.
Reducing wrinkles is another common reason for taking collagen. A 2014 study from the University of Kiel in Germany found that taking a specific collagen peptide orally helped reduce skin wrinkles.
A small study also showed that collagen peptides can improve brittle nails. Some people take collagen for leaky gut, although there are no published studies showing this benefit. Overall, more research into oral collagen and its effect on the body is needed.
