Is nicotinic acid vegan?

Nicotinic acid, also known as niacin or vitamin B3, is a water-soluble vitamin that plays a crucial role in energy metabolism and maintaining healthy skin, nerves, and digestive system. It is a member of the B-complex vitamin family and is naturally found in various food sources such as meat, fish, and whole grains. Nicotinic acid is also available as a dietary supplement and is often used to treat niacin deficiency, high cholesterol levels, and cardiovascular disease. However, consuming high doses of nicotinic acid can cause adverse effects such as flushing, itching, and liver damage, so it should be used under the supervision of a healthcare professional.
