Why choose this product

USA-Sourced Purity & Potency

21st Century Niacinamide is sourced directly from authorized US retailers and authorized brand partners, ensuring authenticity and adherence to stringent cGMP manufacturing standards. Unlike many local alternatives, this product guarantees label potency and purity, free from added sugars, salt, yeast, preservatives, artificial flavors, or colors. It's a clean, vegan, and gluten-free formulation trusted for over 30 years, providing a reliable source of Vitamin B-3 for your health regimen.

Ideal For Daily Wellness Seekers

This prolonged-release Niacinamide is perfect for individuals seeking to support energy metabolism, nerve function, and skin health. It's especially beneficial for vegetarians and vegans due to its formulation and lack of animal-derived ingredients. Those looking for a B-3 source with a lower flushing effect than niacin will find this ideal. However, individuals with specific medical conditions or those taking prescription medications should consult a healthcare provider before use, as with any supplement.

How to use

  • Take One Tablet Daily — As a vitamin supplement, adults should take one (1) tablet each day. It is best to take it with any meal to aid absorption and minimize potential discomfort.
  • Ensure Consistent Intake — For optimal benefits, maintain a consistent daily intake. The prolonged release mechanism works best when nutrients are delivered steadily over time, supporting your body's energy conversion processes throughout the day.
  • Store Properly — Store the tablets at room temperature, away from direct sunlight and moisture. Ensure the bottle is tightly closed after each use to maintain freshness and potency until the expiration date.
