Vitamin B3 (niacin or vitamin PP), like other vitamins from the B-group, is a necessary component for many life processes. It has an influence on metabolism whose aim is to release energy, which is necessary for the proper synthesis of certain hormones (including crucial, from the men’s point of view, testosterone) and participates in the metabolism of proteins, fats and carbohydrates.
The regular use of niacin helps to improve the lipid profile. It effectively reduces the level of "bad" cholesterol (LDL) and triglycerides, as it raises the level of HDL (the "good" cholesterol). This protects us from atherosclerosis and other metabolic diseases.
Niacin is very successful in the treatment of depression. It determines the proper brain function, shows remarkable effectiveness in the treatment of neurosis and anxiety attacks as well as has soothing and relaxing properties. It can also improve the mental capacity. It has been proven that vitamin B3 helps to reduce the number of migraines.
Moreover, niacin promotes our immune system, helps to remove toxins from the body system and shows antifungal properties. It improves the appearance of skin, inhibits hair loss and helps to fight dandruff.
Vegetarians and people who consume small amounts of meat are especially vulnerable to the deficiency of vitamin B3 because the niacin which is present in cereal products is very poorly absorbed. The poorly balanced diet, malnutrition and alcohol abuse also dangerously reduce niacin levels. The impaired niacin metabolism has been also observed in people who suffer from depression and schizophrenia.
In supplementation, vitamin B3 occurs in three forms: as nicotinic acid, the amide of nicotinic acid and inositol hexanicotinate. The nicotinic acid is characterised by the greatest bioavailability.
