Each two-capsule serving delivers 250 mg of nicotinamide riboside, a vitamin B3 form the body converts into NAD+, a coenzyme essential to mitochondrial energy production and DNA repair that naturally declines with age. The 50 mg of pterostilbene is included as a polyphenol intended to support sirtuin signaling pathways tied to cellular stress response.
Two daily capsules supply 900 mg of nicotinamide mononucleotide (NMN), a direct NAD+ precursor that feeds the coenzyme driving mitochondrial energy and DNA repair. The formula layers in 50 mg trans-resveratrol and ergothioneine as antioxidant and sirtuin-support compounds, plus olive-fruit hydroxytyrosol and vitamin D3 as complementary healthspan ingredients.
In an 8-week randomized, double-blind, placebo-controlled trial of 120 healthy adults aged 60-80 published in npj Aging and Mechanisms of Disease, the recommended dose raised whole-blood NAD+ by roughly 40% versus placebo (and ~90% at double dose), sustained over the study period with no serious adverse events. The evidence establishes that Basis reliably increases NAD+; it does not yet demonstrate clinical longevity or disease outcomes.
Independent randomized trials of NMN (for example, a 2023 study in healthy middle-aged adults) show that daily NMN supplementation reliably raises blood NAD+ and is generally well tolerated, with some trials reporting improvements in physical performance markers like walking distance. However, Wonderfeel's specific multi-ingredient formula has not been tested in its own published human trial, so efficacy is inferred from ingredient-level evidence rather than the finished product.
Generally well tolerated; the published trial reported no serious adverse events. Mild, infrequent effects can include nausea, headache, or warmth/flushing typical of the niacin family. Stop and consult a clinician if you notice an unexpected reaction.
NMN at these doses is generally well tolerated in human studies. Infrequent effects can include mild digestive upset, headache, or flushing. Discontinue and consult a clinician if you experience an unexpected reaction.
