Vitamin B3 (Niacinamide) No Flush

Vitamin B3 (Niacinamide) 500mg — No Flush

Niacinamide (also known as nicotinamide) is a form of Vitamin B3 and one of the most important precursors to NAD⁺ (nicotinamide adenine dinucleotide) — a coenzyme found in every living cell and essential for cellular energy production, DNA repair, and the regulation of hundreds of enzymatic reactions. NAD⁺ is often described as one of the most fundamental molecules in cellular biology, and maintaining adequate NAD⁺ levels is a central focus of contemporary longevity and metabolic wellness research.

This product provides Niacinamide — the amide form of Vitamin B3 — at 500mg per capsule. Unlike Niacin (nicotinic acid), Niacinamide does not cause the characteristic skin flushing response associated with high-dose niacin, making it the preferred form for those who wish to avoid the flush. It is one of the most extensively researched forms of Vitamin B3 in contemporary nutritional science.

NAD⁺ — The Cellular Energy Currency

NAD⁺ (nicotinamide adenine dinucleotide) is a coenzyme present in every cell of the body and is essential for:

• Cellular energy production (ATP synthesis) — NAD⁺ is the primary electron carrier in the mitochondrial electron transport chain; it is the central molecule in cellular respiration and ATP production
• DNA repair — NAD⁺ is required for the activity of PARP enzymes (poly ADP-ribose polymerases), which are the primary DNA repair enzymes in the cell
• Sirtuin activation — NAD⁺ is required for the activity of sirtuins (SIRT1–7), a family of NAD⁺-dependent enzymes involved in gene expression regulation, metabolic wellness, and cellular stress response
• Redox reactions — NAD⁺/NADH and NADP⁺/NADPH are the primary redox coenzyme pairs in cellular metabolism, involved in hundreds of enzymatic reactions

NAD⁺ levels naturally decline with age, and supporting NAD⁺ precursor intake through Niacinamide supplementation is a well-established nutritional strategy in contemporary metabolic and longevity wellness practice. Dr. Ray Peat’s work on cellular metabolism and the role of B vitamins in mitochondrial function provides a compelling framework for understanding Niacinamide’s role in metabolic wellness.

Key Nutritional Roles of Niacinamide

• Cellular energy & mitochondrial wellness — as a NAD⁺ precursor, Niacinamide supports the mitochondrial electron transport chain and cellular ATP production; it is one of the most important B vitamins for cellular energy wellness
• DNA repair & genomic stability — NAD⁺ derived from Niacinamide is required for PARP enzyme activity and DNA repair; adequate Niacinamide intake supports genomic stability and cellular wellness
• Skin wellness — Niacinamide is one of the most extensively researched topical and oral nutrients for skin wellness; it plays a role in keratinocyte function, skin barrier integrity, and skin antioxidant defence
• Cognitive & neurological wellness — NAD⁺ is required for normal neuronal function and plays a role in cognitive wellness; Niacinamide has generated significant research interest in the context of neurological wellness
• Metabolic wellness — Niacinamide plays a role in carbohydrate, fat, and protein metabolism through its role as a NAD⁺/NADP⁺ precursor; it is required for normal metabolic function
• Liver wellness — NAD⁺ is required for normal liver metabolic function and detoxification pathways; Niacinamide supports liver wellness through its role as a NAD⁺ precursor
• Immune function — Niacinamide plays a role in immune cell function and the regulation of inflammatory signalling pathways

Niacinamide vs Niacin — What’s the Difference?

Niacin (nicotinic acid) is the acid form of Vitamin B3. At doses above approximately 50mg, niacin causes a characteristic skin flushing response — a temporary reddening and warming of the skin caused by prostaglandin-mediated vasodilation. While the flush is harmless, it can be uncomfortable and is a common reason people discontinue niacin supplementation.

Niacinamide (nicotinamide) is the amide form of Vitamin B3 and does not cause flushing at any dose. It is equally effective as a NAD⁺ precursor and is the preferred form for those who wish to avoid the flush. This product is the No Flush form.

How to Use

Take 1 capsule daily as a dietary supplement, or as directed by your healthcare practitioner. Can be taken with or without food. Dose can be increased under practitioner guidance.

Precautions

Generally very well tolerated at standard supplemental doses. At very high doses (above 3,000mg/day), Niacinamide may affect liver enzyme levels — consult your healthcare practitioner before use at high doses or for long-term use. Consult your healthcare practitioner before use if you are pregnant or breastfeeding. Consult your healthcare practitioner before use if you are taking medications for diabetes or blood pressure. Keep out of reach of children.
