Nicotinic acid, also known as niacin, is a water-soluble vitamin that is found in a variety of foods such as meats, fish, and whole grains. It is a member of the B-complex family of vitamins, which are essential for the proper functioning of the body. Niacin plays an important role in many processes in the body, including the metabolism of carbohydrates and fats, the production of hormones, and the maintenance of healthy skin and nerves.
In the body, niacin is converted into nicotinamide, which is the active form of the vitamin. Nicotinamide is involved in several important reactions in the body, including the production of energy, the synthesis of fatty acids, and the metabolism of amino acids.
One of the key functions of niacin is its role in the synthesis of nicotinamide adenine dinucleotide (NAD), which is an important coenzyme that is involved in many reactions in the body. NAD is essential for the proper functioning of the body's cells, and it plays a critical role in the production of energy from carbohydrates, fats, and proteins.
Niacin is also important for the maintenance of healthy skin, nerves, and digestion. It helps to maintain healthy blood sugar levels, and it may also help to lower cholesterol levels in the blood. Niacin is also thought to have anti-inflammatory properties, which may be beneficial for people with certain health conditions such as arthritis.
Niacin is found in a variety of foods, including meats, fish, and whole grains. It is also available as a dietary supplement, and it is often added to fortified foods such as breakfast cereals.
Niacin can cause a temporary flushing of the skin when it is taken in large doses. This is because niacin causes the blood vessels in the skin to dilate, which can cause a feeling of warmth and a red, flushed appearance.
The flushing effect of niacin is caused by the release of histamine and other chemicals in the body. These chemicals cause the blood vessels to dilate, which increases blood flow to the skin and can cause the flushed appearance.
The flushing effect of niacin is generally harmless, although it can be uncomfortable for some people. It typically lasts for about 30 minutes and can be managed by taking niacin with food or starting with a low dose and gradually increasing it.
