Niacin

Niacin, also known as vitamin B3, is an essential nutrient that helps your body convert food into energy. It supports healthy skin, digestion, and nerve function. Niacin also plays a role in maintaining cholesterol levels; in appropriate amounts, it can help reduce bad cholesterol (LDL) and triglycerides, while increasing good cholesterol (HDL). Found in foods like meat, fish, nuts, and grains, niacin is vital for overall health. In high doses, it may be used under medical supervision to manage cholesterol, but excessive intake can cause side effects like flushing or liver issues.
