Niacin, also known as vitamin B3, is a water-soluble vitamin that is essential for the proper function of the body. It plays a vital role in converting food into energy and is necessary for maintaining the health of the skin, nerves, and digestive system.

Niacin is found naturally in many foods, including meat, poultry, fish, legumes, and whole grains. It can also be synthesized by the body from the amino acid tryptophan.

Niacin is important for the proper functioning of enzymes involved in energy metabolism and DNA repair. It also helps to lower cholesterol levels by reducing the production of low-density lipoprotein (LDL) cholesterol, commonly known as "bad" cholesterol, and increasing the production of high-density lipoprotein (HDL) cholesterol, known as "good" cholesterol.

Niacin deficiency can lead to a condition called pellagra, which is characterized by dermatitis, diarrhea, and dementia. However, excessive intake of niacin supplements can lead to niacin toxicity, which can cause flushing, itching, and liver damage.

Niacin is commonly available in supplement form, either as nicotinic acid or niacinamide. It is also added to many fortified foods, such as cereals and energy bars, and is commonly used as a dietary supplement to treat high cholesterol, cardiovascular disease, and diabetes.
