Vitamins in the B group are necessary for proper metabolism and cell formation. Vitamin C is responsible for infection resistance and healing. Vitamin D is vital for proper bone formation. Vitamin E ensures cell protection and stability. Vitamin K is responsible for proper blood clotting.
All humans require vitamins in varying amounts depending on the age and gender of the individual.
Many people worry that they are not receiving the proper amounts of vitamins and choose to supplement their diets. Many experts agree, including those at the American Dietetic Association and the National Academy of Sciences, that the best way to get the vitamins needed is through a balanced diet. If vitamin supplements are taken, it is best to avoid over-supplementation. Consuming large amounts of vitamins can have toxic effects. Vitamins A, D, E, and K are fat-soluble vitamins, meaning that any excess vitamins not used by the body are stored in the body's fat.
