ENDUR-AMIDE SR 500 mg 90 Tablets

ENDUR-AMIDE Sustained Release Niacinamide 500mg — NAD+ Precursor for Cellular Energy, DNA Repair, and Skin Health

ENDUR-AMIDE SR from Endurance Products Company delivers 500mg of niacinamide (nicotinamide, the amide form of niacin/vitamin B3) in a proprietary vegetable-based wax matrix that releases the nutrient gradually over 5–7 hours — the sustained-release profile that has made ENDUR-AMIDE the preferred form of niacinamide among clinical researchers. Niacinamide and nicotinic acid (niacin) share many biochemical functions but differ importantly in their clinical applications: where nicotinic acid is the doctor-preferred form for cardiovascular and cholesterol support, niacinamide is the preferred form for NAD+ precursor supplementation, skin health, healthy aging, and cellular DNA maintenance.

Niacinamide serves as the primary dietary precursor for NAD+ (nicotinamide adenine dinucleotide) — the critical coenzyme involved in over 500 enzymatic reactions including oxidative phosphorylation, fatty acid metabolism, and SIRT1/SIRT3 sirtuin activation that underlies many of the cellular longevity pathways currently under intense scientific research. NAD+ levels decline significantly with age, and maintaining NAD+ sufficiency through niacinamide supplementation supports cellular energy production, DNA repair enzyme (PARP) activity, and the mitochondrial biogenesis signaling that sustains cellular vitality. At the neurological level, neurons are particularly sensitive to NAD+ balance — niacinamide may support healthy neuron function through its influence on NAD+ within neural tissue.

• Niacinamide (nicotinamide) 500mg per tablet — NAD+ precursor for cellular energy and aging support
