Nicotinamide Extra Pure
Original price was: $ 17.40.$ 17.34Current price is: $ 17.34.
Nicotinamide Extra Pure is a refined, high-purity form of vitamin B3, widely recognized for its essential role in human and animal health. It serves as a vital component in the synthesis of NAD⁺ and NADP⁺, coenzymes that are fundamental to numerous metabolic and enzymatic reactions in living cells. In laboratory settings, it is frequently used in biochemical research, cell culture media, and vitamin assays due to its stable and bioactive nature.
In pharmaceutical applications, nicotinamide is commonly used in the formulation of supplements and dermatological treatments, where it supports skin barrier function, reduces inflammation, and helps alleviate acne and hyperpigmentation. Its presence in cosmetic products is valued for promoting smoother, more even-toned skin. The Extra Pure grade guarantees minimal impurities, making it ideal for sensitive applications in health care, research, and personal care products. It should be stored in a cool, dry environment away from light to maintain its integrity.
