NOW Niacinamide 500 mg – Vitamin B-3, No Flush, Energy Production, 100 Veg Capsules

What Is NOW Niacinamide 500 mg?

NOW Niacinamide 500 mg delivers a therapeutic dose of Niacinamide (Nicotinamide) — the non-flushing amide form of Vitamin B-3 — one of the eight essential B vitamins and a foundational molecule in human cellular metabolism. Unlike Niacin (nicotinic acid), which causes the well-known “niacin flush” (skin redness, tingling, and warmth) at higher doses, Niacinamide delivers all the core metabolic benefits of Vitamin B-3 without the flush response, making it the preferred form for daily supplementation. At the heart of its function, Niacinamide is a direct precursor to NAD+ (Nicotinamide Adenine Dinucleotide) — the master coenzyme involved in over 500 enzymatic reactions and arguably the most important molecule in cellular energy metabolism and longevity science.

What Does Niacinamide Do?

• Energy production — As a NAD+ precursor, niacinamide is essential for converting carbohydrates, fats, and proteins into cellular energy (ATP) via the Krebs cycle and electron transport chain
• NAD+ support — NAD+ levels decline with age; niacinamide is a direct, cost-effective pathway to supporting NAD+ synthesis for cellular vitality and longevity
• DNA repair — NAD+ is required by PARP enzymes that detect and repair DNA strand breaks, protecting genomic integrity
• Skin health — Niacinamide is one of the most extensively researched topical and oral ingredients for skin barrier function, hyperpigmentation, pore size, and sebum regulation
• Nervous system health — Supports healthy neurological function and neurotransmitter synthesis
• Joint comfort — Research suggests niacinamide may support joint mobility and comfort through anti-inflammatory pathways
• Blood sugar metabolism — Involved in glucose metabolism and insulin sensitivity pathways

Niacinamide vs. Niacin — What’s the Difference?

• Niacinamide (this product) — No flush, supports NAD+, DNA repair, skin health, and energy metabolism. Does NOT significantly raise HDL cholesterol.
• Niacin (nicotinic acid) — Causes flushing, but is used therapeutically at high doses to raise HDL and lower triglycerides under medical supervision.

Who Should Take This?

• Anyone seeking the energy and metabolic benefits of Vitamin B-3 without the flush side effect
• Individuals interested in NAD+ support for cellular energy and healthy aging
• Those supporting skin health from the inside out
• People seeking DNA repair and genomic health support
• Individuals with high stress, fatigue, or high carbohydrate metabolism demands

How to Use

Take 1 capsule 1 to 2 times daily with food, or as directed by your healthcare practitioner. Niacinamide is water-soluble and consistent daily use is key to maintaining optimal B-3 and NAD+ levels.
