Vitamins are an essential nutrient group that facilitates many of the body’s mechanisms and functions. The health benefits of vitamins include the ability to prevent and treat various diseases including heart problems, high cholesterol levels, eye disorders and skin disorders.
Vitamin A, D, E and K are fat-soluble vitamins. These vitamins are stored in the liver and fatty tissues in the body. As they are stored in the body and eliminated much more slowly than water-soluble vitamins they need not be consumed as often as water-soluble vitamins. If your intake of fat soluble vitamins is much higher than you need then it could become toxic. Human body is especially sensitive to excess of vitamin A and vitamin D.
