Iron. Elizabeth Ward, a registered dietitian, does not recommend taking iron supplements without a doctor’s advice. This is because in people with hemochromatosis (an inherited condition in which the body absorbs too much iron), iron can accumulate in the liver, heart, and pancreas. You may not even know you have this disease: it occurs in 1 in 200-400 people.
resveratrol. The required doses of this substance for the effects observed in studies (heart benefits and anti-aging) are much higher than supplements. Additionally, excess resveratrol in supplement form may interfere with the action of blood-thinning medications and may also lead to gastrointestinal side effects.
vitamin C. Orlando-based registered dietitian Joanna Katz notes that overdoses of this vitamin can interfere with the body’s defense mechanisms. They can suppress the body’s endogenous antioxidant response system, which combats oxidative stress most effectively.
vitamin E. Studies examining its effects on longevity have produced mixed results. Some even say that high doses of this vitamin can disrupt the body’s oxidative balance and potentially increase the risk of cardiovascular problems and cancer.
