Collagen supplements may have other health benefits, but these have not been studied extensively.
- Hair and nails: Taking collagen may increase the strength of your nails by preventing brittleness. Additionally, it may stimulate your hair and nails to grow longer.
- Gut health: Although there is no scientific evidence to support this claim, some health practitioners promote the use of collagen supplements to treat intestinal permeability, or leaky gut syndrome.
- Brain health: No studies have examined the role of collagen supplements in brain health. However, some people claim they improve mood and reduce symptoms of anxiety.
As you can see, studies around collagen supplementation are extensive but to date, we still are not definite whether most people would benefit from supplementation. Perhaps only a very particular group of people may currently benefit and they include athletes and those suffering from joint disorders.
