Skin Brightening · Barrier Support · Energy Metabolism · 100 Tablets
As a leading manufacturer and trusted supplier of premium nutritional supplements, we present DUOZI Niacinamide Vitamin B3 500mg Tablets – a high‑potency, essential nutrient designed to support skin health, brighten complexion, and promote energy metabolism. Niacinamide (Vitamin B3) is a water‑soluble vitamin that plays a critical role in over 200 enzymatic reactions in the body. This advanced formula helps support skin brightening by inhibiting melanin transfer, improve skin barrier condition by supporting ceramide production, and promote energy metabolism by aiding in the conversion of food into cellular energy. With 100 tablets per bottle, it provides a generous 100‑day supply at the recommended dose of 1 tablet daily – ideal for adults seeking comprehensive skin and metabolic wellness support.
Niacinamide reduces the transfer of melanin from melanocytes to keratinocytes, helping to fade dark spots, reduce hyperpigmentation, and promote a brighter, more even complexion.
Niacinamide supports the production of ceramides and fatty acids, strengthening the skin barrier – helping to retain moisture, reduce redness, and protect against environmental stressors.
Vitamin B3 is essential for the conversion of carbohydrates, fats, and proteins into cellular energy (ATP) – helping to reduce fatigue and support sustained vitality throughout the day.
Each tablet provides a therapeutic 500mg dose of Niacinamide – a clinically effective level for skin and metabolic support. With 100 tablets per bottle, it offers excellent value for long‑term use.
Made with premium, non‑GMO ingredients and free from artificial additives, gluten, and unnecessary fillers – a pure supplement you can trust for daily use.
