It’s very important that you eat right to insure you’re getting al the vitamins and minerals you need. Supplements can help, but certainly don’t rely on getting your daily recommended allowances through a supplement. Fact is, your body only absorbs 10% to 15% of the nutrients in pills. Your body would much rather break down foods to get nutrients, so before you spend extra money on supplements, make sure you’re eating healthy. If you eat a variety of foods, you’ll probably meet the requirements of vitamins and minerals you need each day. If you’re dieting and you are consuming less than 1500 calories per day, you might be missing some of the important nutrients and a multivitamin would be a good idea. Try to take it approximately the same time each day with food. There is no evidence that extra intake of vitamins and minerals improve your performance. What your body doesn’t need, it doesn’t keep.
