Vitamins and minerals are micronutrients that serve a specific purpose and benefit the body in a unique way. For example, vitamin A supports vision and bone growth, whereas vitamin E strengthens the immune system and helps repair DNA. Vitamin and mineral deficiency can impair the body’s ability to heal and protect itself.
Taking vitamins does not make up for an unhealthy diet, and vitamins are an insufficient substitute for nutrients from fresh fruits, vegetables, and whole grains. However, a general multivitamin and mineral supplement can be a good safeguard against periodic vitamin shortfalls in your diet.
