Nutritional supplements are substances which add nutrients to the diet or to lower the risk of health problems, like osteoporosis or arthritis. Nutritional Supplements include vitamins, minerals, fiber, amino acids, herbs or other plants, or enzymes. Sometimes, dietary supplements are also added to foods and drinks. However, only a certain amount of each nutrient is needed for our bodies to function, and higher amounts are not necessarily better as it may cause adverse effects, and may become harmful.
