Most people don't need to take vitamin supplements to get the essential vitamins and minerals their body needs. Eating a healthy, balanced diet is usually enough to provide the nutrients necessary for proper functioning. However, evidence suggests that certain supplements may improve health in different ways. The most popular nutritional supplements are multivitamins, calcium, and vitamins B, C, and D.
Calcium is important for bone health and vitamin D helps the body absorb it. Vitamins C and E are antioxidants that protect cells from damage and help maintain overall health. But can a multivitamin help if you know your diet isn't that healthy? Not necessarily. Studies have shown that multivitamins don't prevent memory loss, heart disease, or cancer.
On the other hand, taking too many nutrients in pill form can be harmful. Experts often recommend getting vitamins and minerals from food sources instead of supplements. Athletes who consume a lot of supplements may be doing more harm than good to their bodies.
