Vitamin B3 (Niacin)

Vitamin B3 (Niacin) is a water-soluble vitamin essential for energy production, DNA repair, and cell signaling. It exists in two main forms: nicotinic acid and niacinamide. Niacin is critical for preventing pellagra and may be used to manage cholesterol levels at higher doses, although such usage can lead to side effects. Niacinamide is generally better tolerated regarding flushing. Supplementation should be approached cautiously, particularly at higher doses, and under the guidance of a healthcare professional, especially for individuals with pre-existing medical conditions. The specific form of niacin used (nicotinic acid vs. niacinamide) and the dosage should be carefully considered to optimize benefits and minimize potential side effects.
