Dietary and nutritional supplements are a widespread and massive industry - but do they work? And, once again the answer is “it depends.” By the very nature of the word, the intent is to supplement one’s diet, not replace or cover for a bad diet. That said, the average person is likely to have a diet in which not all vitamin/mineral/fiber/micro nutrient needs are being met - hence the potential benefit of supplementation. Scientific evidence shows that some dietary supplements are beneficial for overall health and for managing some health conditions. For example, calcium and vitamin D support bone health; Vitamins C and E are antioxidants - that help to prevent cell damage and help to maintain health; and omega-3 fatty acids from fish oils might help some people with heart disease. With more than ½ of the US population taking a dietary supplement daily or “on occasion,” it’s worth taking a closer look at this.
