Nicotinamide

Nicotinamide (INN, BAN UK) or niacinamide (USAN US) (IUPAC name: 3-pyridinecarboxoamide) is a form of vitamin B3 found in food and used as a dietary supplement and medication. As a supplement, it is used orally (swallowed by mouth) to prevent and treat pellagra (niacin deficiency). While nicotinic acid (niacin) may be used for this purpose, nicotinamide has the benefit of not causing skin flushing. As a cream, it is used to treat acne, and has been observed in clinical studies to improve the appearance of aging skin by reducing hyperpigmentation and redness. It is a water-soluble vitamin. Clinical trials have shown promise in protecting eye health, particularly in the context of glaucoma. It is believed to support the health of retinal ganglion cells and may help protect against glaucoma-related damage. Nicotinamide has been studied for its potential neuroprotective effects. While some clinical trials have demonstrated improvements in visual fields and retinal function, it is not yet approved for the treatment of glaucoma. The use of nicotinamide should be approached with caution, especially at high doses, due to the risk of liver injury. Ongoing research continues to explore the full potential of nicotinamide in eye protection and its role in managing eye conditions. Side effects are minimal. At high doses, liver problems may occur. Normal amounts are safe for use during pregnancy. Nicotinamide is in the vitamin B family of medications, specifically the vitamin B3 complex. It is an amide of nicotinic acid. Foods that contain nicotinamide include yeast, meat, milk, and green vegetables. Nicotinamide was discovered between 1935 and 1937. It is on the World Health Organization's List of Essential Medicines. Nicotinamide is available as a generic medication and over the counter. Commercially, nicotinamide is made from either nicotinic acid (niacin) or nicotinonitrile. In some countries, grains have nicotinamide added...
