Usage

General Description

3,4-pyridinedicarboxamide, also known as niacinamide, is a form of vitamin B3 with a chemical formula C6H6N2O. It is a white, crystalline powder that is water-soluble and odorless. Niacinamide is a key component in the production of NAD+ (nicotinamide adenine dinucleotide), a coenzyme involved in various cellular processes, including energy production and DNA repair. As a dietary supplement, it is used to treat and prevent vitamin B3 deficiency and its associated symptoms, such as pellagra. In skincare, niacinamide is known for its anti-inflammatory and antioxidant properties, making it an effective ingredient in acne treatment, wrinkle reduction, and overall skin health. Additionally, it has been studied for its potential therapeutic effects in conditions such as diabetes, arthritis, and dermatitis.
