Vitamins are small molecules (Vitamin B12 is the largest, with a molecular weight of 1,355) that your body needs to keep itself running properly. We know that the body can produce its own Vitamin D through exposure to the sun, but generally vitamins must be provided in food. Unfortunately most of the food we eat has been processed in some way or another and has lost many of its vitamins and minerals in the process. Taking vitamins helps fill the gap.

The Human Body Needs 13 different vitamins: In most cases, the lack of a vitamin causes severe problems.

The following list shows diseases associated with the lack of different vitamins:
Lack of Vitamin A: Night blindness, xerophthalmia

According to a review in the Journal of American Medical Association in 2002, there is “strong evidence” that the North American diet only provides “suboptimal levels” of vitamins and minerals and that supplementation with a multivitamin dietary supplement can help to bolster long-term cardiovascular health, cell health and bone health. Essentials contain the vitamins and minerals in the amounts needed to combat the effects of age on the body and obtain the healthiest possible future.
