Niacinamide is a form of vitamin B3.
Understanding Niacinamide and Vitamin B3
Niacinamide, also known as nicotinamide, is one of two major forms of vitamin B3 (niacin). The other primary form is nicotinic acid. Both forms are crucial for various bodily functions.
Key Roles of Vitamin B3 (Including Niacinamide)
Vitamin B3, whether in the form of niacinamide or nicotinic acid, plays a vital role in:
- Energy Production: B3 is essential for converting food into usable energy.
- Cellular Health: It contributes to the health of skin cells, nerve cells, and digestive system cells.
- DNA Repair: B3 assists in DNA repair processes.
- Antioxidant Activity: It acts as an antioxidant, protecting cells from damage.
Niacinamide vs. Nicotinic Acid
While both are forms of vitamin B3, niacinamide and nicotinic acid have different effects on the body. A key difference is that nicotinic acid can cause skin flushing (redness, warmth, itching), while niacinamide typically does not. This makes niacinamide a preferred form in many supplements and skincare products.
Sources of Vitamin B3
Vitamin B3 can be obtained from various dietary sources, including:
- Meat
