on 10/1/18The Marine Collagen + has fish based hydrolyzed collagen, Vitamin C and silicon (from bamboo). Mostly natural stuff but you can be seriously allergic to fish collagen.
Their ingredients generally don't contain any common allergens, such as wheat, nuts, dairy or eggs. But the Anti-Aging Formula does contain something called tocopherols derived from refined soy, which may cause a reaction.
