B3vitamiinia

B3vitamiinia, also known as niacin or nicotinic acid, is an essential vitamin for human health. It belongs to the B vitamin group, which are crucial for various metabolic processes. Niacin plays a vital role in converting food into energy, supporting the digestive system, skin, and nervous system functions. It is also involved in DNA repair and the production of hormones.

A deficiency in B3vitamiinia can lead to a condition called pellagra. Symptoms of pellagra include dermatitis, diarrhea, and dementia. Severe cases can be fatal if left untreated. Fortunately, pellagra is rare in developed countries due to the fortification of food products and the availability of dietary supplements.

Good sources of niacin include lean meats, poultry, fish, nuts, legumes, and whole grains. The recommended daily intake varies depending on age, sex, and life stage. Niacin is water-soluble, meaning the body does not store large amounts of it, and excess amounts are typically excreted in urine.

Niacin is available in several forms, including nicotinic acid and niacinamide. While both are effective sources of vitamin B3, nicotinic acid can cause a temporary flushing sensation in some individuals. Niacinamide does not typically cause this side effect. It is important to consult with a healthcare professional before taking niacin supplements, especially in high doses, as it can interact with certain medications and may have side effects.
