Vitamin B3 / Niacin (Nicotinic Acid)

Niacin (nicotinic acid) was first synthesized in 1867 by means of the oxidative degradation of nicotine. It had been chemically identified long before its importance as an essential nutrient was recognised. In the early 1900s, it was discovered that pellagra, a disease with symptoms affecting the skin, gastrointestinal tract and central nervous system, was caused by niacin deficiency. In 1935, niacin was shown to be a moiety of the coenzymes NAD and NADP, indispensable for many biochemical reactions. 

Main function

Energy metabolism

Biological functions

Niacin is a B vitamin with a coenzyme function. In its active forms, the pyridine coenzymes NAD (nicotinamide adenine dinucleotide) and NADP (nicotinamide adenine dinucleotide phosphate) are all involved in the pathways of energy metabolism, such as glycolysis, the citric acid cycle, oxidation of fatty acids, gluconeogenesis and de novo fatty-acid synthesis.
In physiological terms, nicotinic acid and nicotinamide can be considered equal sources of niacin.

Benefits for the animal

Proper niacin supplementation maximises weight gain. It optimises feed efficiency, ensures the proper utilisation of other nutrients and supports general health and well-being.
