The B vitamins and vitamin C need to be replenished every day to meet the body's needs. If you work out regularly, you may want to pay special attention to these nutrients, as they play significant (although very different) roles in exercise.

The B vitamins help release energy from carbohydrates, fats and proteins. Without adequate amounts of the B vitamins, the body lacks the energy needed for exercise. Some foods that contain B vitamins include fortified cereals, rainbow trout, salmon, tuna, chicken, yogurt, milk and cheese.

Vitamin C helps the body deal with the effects of exercise. A potent antioxidant, vitamin C protects the body against cell damage that can occur during exercise. Some foods that contain vitamin C include red bell peppers, broccoli, guava, oranges, orange juice, papaya, and strawberries.

It is certainly possible to get the necessary amounts of Bs and Cs from food. However, our busy lifestyles often get in the way of making nutritious food choices that give us the vitamins we need each day. In these cases, taking supplements can be an excellent way to get all of the vitamins and minerals needed for good health.
