Niacin is also known as vitamin B3, and it’s an essential vitamin that is involved in a wide range of metabolic processes. But sometimes it’s difficult to get enough niacin from your diet, especially if you’re following a vegan or vegetarian diet, or if you have a niacin deficiency. Taking niacin supplements can help you make up for any niacin deficiencies.
