What is Niacin (as Niacinamide)?

Niacin (as Niacinamide) is a Vitamin supplement available in 1 form.

Not all forms of Niacin (as Niacinamide) are equal. The form you choose determines how much Niacin (as Niacinamide) actually reaches your tissues, and the difference between the best and worst forms can be substantial. Niacinamide (nicotinamide) is the amide form of niacin (vitamin B3) that does not cause the flushing associated with nicotinic acid while providing the same NAD+ biosynthetic support. Research supports niacinamide for promoting healthy NAD+ levels, DNA repair, cellular energy production, and skin barrier function.

Forms of Niacin (as Niacinamide) Compared

Niacin (as Niacinamide) Preferred (Preferred Form) has a bioavailability rating of good absorption.

What the Research Shows

Niacinamide (nicotinamide) is the amide form of vitamin B3 that does not cause the flushing associated with nicotinic acid. Research supports its role in NAD+ synthesis, skin barrier function (widely used in dermatology), and joint comfort. Unlike niacin, niacinamide does not significantly affect lipid profiles but provides superior NAD+ precursor activity for cellular energy.

Oral nicotinamide was rapidly absorbed in healthy volunteers, with the standard form achieving significantly higher peak plasma concentrations and bioavailability than sustained-release preparations. PMID: 7859933
