Collagen Side Effects
The side effects of taking collagen supplements vary depending on what type of collagen supplement has been used. Collagen creams will have a substantial effect on the wallet and not on the face or skin. Oral collagen supplements will only pose a danger if one has food sensitivities; most collagen supplements are made from products obtained from cows or chickens. Collagen injections may produce certain side-effects on individuals with allergic reactions to injections. However, tests are normally done before the injection to determine if the person has this kind of allergy. Those with auto-immune disorders such as herpes simplex may experience a flare-up because the body is reacting to the new substance.
