Vitamins are essential nutrients but the body only needs them in small amounts for a variety of essential processes. The body cannot produce most vitamins on its own, so the body needs to obtain vitamins from the diet. Vitamins are grouped into fat-soluble vitamins and water-soluble vitamins. The need for each vitamin varies with life stages.
1. What are vitamins?
Vitamins are molecules that may be needed in small amounts for a variety of essential processes in the body. They are classified as micronutrients, because they are probably only needed in small amounts, usually a few milligrams (mg) or micrograms (μg) per day. Most vitamins are obtained from foods that provide them and cannot be produced by the body. An exception is vitamin D, which can be synthesized by the body through the action of sunlight on the skin. Or small amounts of niacin (a B vitamin) can be made from the amino acid, tryptophan.
Vitamins have many different functions in the body, including:
Co-factors in enzyme activity Antioxidants (prevents damage caused by free radicals) Pro-hormones (only vitamins) D) If the body does not provide the necessary amount of vitamins due to a poor diet or some medical condition, such as malabsorption or birth defects in metabolism, the body will suffer from dehydration. nutritional deficiencies. Vitamin deficiency diseases are rare in the UK but still occur in some parts of the world.
