For cellular energy, skin health, and NAD+ production without the flushing side effect of regular niacin, this delivers. **Niacinamide** at 500 mg sits right at the top of the clinical dosing range. At this dose, you're supporting NAD+ production — the coenzyme your cells rely on for energy metabolism, DNA repair, and healthy aging. Niacinamide is also well-studied for skin health, with dermatology research using 500 mg daily to support skin barrier function.

Because this is niacinamide rather than nicotinic acid, you won't experience the uncomfortable flushing that comes with regular niacin. The tradeoff is that niacinamide doesn't have the same lipid-modifying effects — it won't raise your HDL or lower triglycerides the way nicotinic acid can.

At 500 mg per capsule, you're well above the 16 mg RDA but within studied supplemental ranges. If your primary goal is cholesterol support rather than cellular energy or skin, nicotinic acid would be the more relevant form of B3 to look for.
