Niacin is a water-soluble B-vitamin essential for various metabolic processes. It belongs to the B-vitamin complex, which plays a crucial role in converting food into energy. The term "niacin" refers to two chemical compounds: nicotinic acid and nicotinamide, both of which are active forms of vitamin B3.

Our bodies require niacin through diet, but it is also synthesized in the skin from the amino acid tryptophan. Major dietary sources include:
- Meat (especially liver and poultry)
- Fish (tuna, salmon)
- Whole grains and fortified cereals
- Legumes
- Peanuts and seeds
- Yeast products
Daily Recommended Intake
The amount of niacin needed varies by age, gender, and physiological status. The general guidelines are:
