B3vitamin

B3 vitamin, also known as niacin or nicotinic acid, is an essential nutrient. It plays a crucial role in energy metabolism, converting food into energy that the body can use. Niacin is also involved in DNA repair and the production of hormones.

The human body cannot produce significant amounts of B3 vitamin, so it must be obtained through diet. Good sources include meat, poultry, fish, whole grains, legumes, nuts, and seeds. Many food products, such as breakfast cereals and bread, are also fortified with niacin.

A deficiency in B3 vitamin can lead to a condition called pellagra. Symptoms of pellagra can include skin rashes, digestive issues, and neurological problems. Severe pellagra can be debilitating and even fatal if left untreated.

While niacin is essential, very high doses, particularly from supplements, can cause side effects. These can include flushing of the skin, itching, and gastrointestinal upset. In rare cases, high doses can lead to liver damage. It is generally recommended to obtain niacin from food sources rather than high-dose supplements, unless advised by a healthcare professional. Niacin supplements are sometimes prescribed to help manage cholesterol levels.
