Effects of NAD+ precursor supplementation on glucose and lipid metabolism in humans: a meta-analysis.
Nutrition & Metabolism (2022) · Meta analysis · n=14750
Meta-analysis of 40 clinical studies (14,750 participants) of four NAD+ precursors: nicotinamide riboside, nicotinamide mononucleotide, nicotinic acid (niacin) and nicotinamide.
The 5 g point is a crossover trial in 123 adults taking 5 g a day for 6 weeks (PMID 37968687): the effect on backward digit span only bordered significance (p = 0.064), reasoning (Raven's matrices) did not change, and side effects were 4.25 times more common than on placebo. The 20 g point is a one-week trial of 5 g four times a day in 32 older adults, where most memory tasks improved (PMID 17828627). A meta-analysis of 10 trials found a small memory benefit (SMD 0.29), mostly in adults aged 66 to 76, with no effect of dose across 2.2 to 20 g a day (PMID 35984306), so the curve is flat. The two trials differ in age and length as well as dose. No minimum or optimal dose is established.
The points come from one 8-week RCT in overweight adults, where 100, 300 and 1,000 mg a day raised whole-blood NAD+ by 22%, 51% and 142%, with no difference in adverse events versus placebo or between doses (PMID 31278280). Other trials at 1 g a day found similar rises, 2.6-fold in older adults with mild cognitive impairment (PMID 37994989). No trial compared doses above 1,000 mg, so no optimal dose is plotted. The ceiling is the 2,000 mg a day that a 12-week RCT in obese men found safe (PMID 29992272). The NR-SAFE trial also found 3,000 mg a day well tolerated over 4 weeks in 10 people with Parkinson's disease (PMID 38016950).
