Niacin (Vitamin B3)

Niacin (nicotinic acid) is a B vitamin that’s used to turn carbohydrates into energy, in the body. It is water-soluble, and so is not stored in the body. So we need a continuous supply of such vitamins in the diet.

Severe deficiency of niacin in the diet causes the disease Pellagra, which is characterized by diarrhea, dermatitis, and dementia, as well as “Casalls necklace” lesions on the lower neck, hyperpigmentation, thickening of the skin, inflammation of the mouth and tongue, digestive disturbances, amnesia, delirium, and eventually death, if left untreated. These symptoms are associated with irritability, poor concentration, anxiety, fatigue, restlessness, apathy, and depression.

Niacin can raise HDL cholesterol — the “good” cholesterol — by 15 to 35 percent. Higher amounts of niacin can improve cholesterol levels and lower cardiovascular risks. It also modestly lowers bad LDL cholesterol.

In addition, niacin is an FDA-approved treatment for pellagra, a rare condition that develops from niacin deficiency.

It participates in at least 200 different chemical reactions involved in energy production. It is also necessary for the production and breakdown of glucose, fats, and amino acids. It controls the development, maintenance, and function of the skin, intestine and stomach, and nervous system. It has a crucial role in manufacturing DNA.
