Vitamin B3, is also known as vitamin PP, nicotinic acid or niacin, is involved in many oxidative processes of cells. It was first artificially obtained in 1867 by scientist Huber, but the vitamin properties of nicotinic acid were proven only in 1937. The effect of this substance on the human body is extremely wide:
– participates in tissue respiration;
– contributes the production of sex hormones;
– reduces cholesterol and glucose in the blood;
– takes part in digestion;
– neutralizes dangerous to health toxins;
– regulates the redox processes in the body;
– improves blood circulation;
– restores hair;
– preserves the health and youth of skin cells;
– has a light sedative effect.
In a small amount, niacin is produced by intestinal bacteria, if there are amino acids called «tryptophan», vitamins B2, B6 and copper in the body. However, the bulk of nicotinic acid comes from food products of both plant and animal origin. Also, vitamin can be taken as an additive – it is synthesized artificially and is available in the form of ampoules for injection or capsules, which are much more convenient for using. Niacin is exclusive vitamin that is officially recognized as a medicine, used to improve the cardiovascular and digestive systems, as well as maintains the elasticity and purity of the skin.
Nicotinic acid is a cosmetic antioxidant active that is used against pigmentation and wrinkles. It restores the integrity of the lipid layer, gives the skin smoothness, elasticity, radiance, reduces flaking and prevents moisture loss. Vitamin B3 protects the dermis from the negative effects of ultraviolet radiation, corrects its uneven tone, eliminates rashes and stimulates collagen production. It eliminates hypopigmentation, restores tone and improves skin texture. Niacin corrects the work of the sebaceous glands, due to its anti-inflammatory activity.
Deficiency of this substance in the body leads to skin tarnishing and flaking. Besides, a lack of nicotinic acid can affect the overall condition of the body, causing dizziness, migraines, insomnia and depression. A human’s immunity decreases, body is under stress and may even lose weight.
The daily allowance of nicotinic acid for men and women is 20 and 18 mg, respectively. For people older than 60 years, as well as pregnant and lactating women, it increases by 2 – 3 mg. Niacin is found in many foods: rye bread, beans, buckwheat, liver, kidney, and other by-products; also in turkey meat, sunflower seeds, peanuts, wheat germ, brewer’s yeast; potatoes, fresh apples and carrots.
Heat treatment of products does not reduce the beneficial properties of nicotinic acid. It withstands high temperatures (up to 100 degrees) with preservation of medicinal qualities. This makes sure that during cooking a person will receive vitamin B3 in the amount in which it is present in the original product. The component is water soluble so the excess is excreted from the body naturally. Overdose is possible only with prolonged uncontrolled course of synthetic niacin, but in this case must be consumed 60 mg or more per day. Excessive of active substance is accompanied by a rash and redness of the skin. With the optimal amount of vitamin B3 consumed, it will be an important component of establishing the mechanisms of the organism’s work, high metabolism, also returning skin beauty, cleanliness and healthy appearance.
