From the manufacturer

Product description

Size:100 Count (Pack of 1)  |  Product Packaging:Standard Packaging

Many B vitamins are used in the body individually or in combination with enzymes to help release energy from carbohydrates, fat, and protein. Vitamin B coenzymes are crucial to the metabolic pathways that generate the energy needed by every cell in the body. Because they are codependent in their metabolic activities, a deficiency of one B vitamin can affect optimal functioning of organ systems throughout the body. Niacin is the only B vitamin that can be synthesized in the liver from the amino acid tryptophan — on average, 1 mg of niacin can be synthesized from the ingestion of 60 mg of tryptophan. In its coenzyme forms, niacin is crucial to energy transfer reactions, particularly the metabolism of glucose, fat, and alcohol. Niacin’s beneficial effects on blood lipids is well-documented.

Important information

Safety Information

A common minor side effect of niacin is a flushing reaction. This might cause burning, tingling, itching, and redness of the face, arms, and chest, as well as headaches. Alcohol can make the flushing reaction worse. Avoid large amounts of alcohol while taking niacin. Other minor side effects of niacin are stomach upset, intestinal gas, dizziness, pain in the mouth. When doses of over 3 grams per day of niacin are taken, more serious side effects can happen. These include liver problems, gout, ulcers of the digestive tract, loss of vision, high blood sugar, irregular heartbeat, and other serious problems. Niacin might also interact with anti-diabetes and anti-hypertensive drugs. Individuals undergoing treatment for a medical condition should talk to their doctor before taking any dietary supplement.

Ingredients

Niacin (vitamin B3) 500mg; Other ingredients: gelatin, vegetable stearate.

Directions
