Should I take a daily vitamin supplement?
My chemistry teacher, Father Wheeler of Kansas City, used to say that the only thing that vitamin supplements affect is your wallet. Research shows that vitamin supplements are only necessary if laboratory tests confirm a deficiency. In fact, unnecessary vitamin intake can be harmful, since fat-soluble vitamins are stored in fatty tissue.
So what are vitamins? Vitamins and minerals are chemicals that are essential for the proper functioning of cellular metabolism.

Fat-soluble vitamins include vitamins A, D, E, and K.
The Endocrine Society has published guidelines suggesting that vitamin D supplements should only be taken by people in certain risk groups, including exclusively breastfed infants, children and adolescents ages 1 to 18, pregnant women, and adults with prediabetes.

Most vitamin E is obtained from nuts, seeds, vegetable oils, green leafy vegetables, and fortified cereals. Daily intake from foods usually meets the daily requirement of 15 mg for adults and children over 4 years of age.

Found in green leafy vegetables, vegetable oils and grains, Vitamin K helps with blood clotting and wound healing. Vitamin K is actually a group of compounds that we need in micrograms per kilogram of body weight, and a balanced diet will provide the daily requirement, with any excess being stored in the liver.
