VITAMIN

Niacinamide (NAD precursor)

Vitamin -- also: niacinamide, nicotinamide

One ingredient, seen the whole way through: what it is, how it works, the honest evidence, the form that matters, the systems it touches, and the studies behind it.

How it works

  • Transform -- converted via the NAD+ salvage pathway into NAD+/NADH, a central cofactor for mitochondrial electron transport and ATP production

  • Maintain -- NAD+ also serves as a substrate for sirtuin and PARP enzymes involved in DNA repair and cellular upkeep

  • Exchange -- unlike nicotinic acid (the other niacin form), niacinamide does not cause the histamine-mediated skin-flushing reaction, which is why it is the form chosen for products like NAD-Power that aim for a comfortable daily-use experience rather than the flush associated with high-dose nicotinic acid therapy

  • Adapt -- at very high doses, niacinamide (unlike nicotinic acid) is instead associated with potential liver enzyme changes in some studies, a distinct high-dose safety profile worth knowing separately from the flushing issue attributed to the other form

Form matters

The same nutrient can be made in very different forms -- and a study done on one form does not automatically apply to another. Methylcobalamin is not cyanocobalamin; magnesium glycinate is not magnesium oxide; a whole-food extract is not the synthetic isolate that was studied. Two things decide whether what is in the bottle behaves like the research: the exact form, and independent lab verification (a Certificate of Analysis) that the form and dose on the label are truly what is inside. Without a COA, you are trusting a label, not the science.
