The Claim
Nicotinamide riboside supplementation at 1000 parts per million in the diet, administered to UM-HET3 mice of both sexes beginning at 8 months of age, did not demonstrate a statistically significant increase in lifespan in either males or females when data were pooled across three independent testing sites.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Scientists fed mice a special vitamin supplement called nicotinamide riboside in their food starting when the mice were middle-aged, then tracked how long they lived. The supplement didn't make the mice live longer.
See the scientific wording
Nicotinamide riboside (1000 ppm in diet) administered to UM-HET3 mice of both sexes starting at 8 months of age was not associated with significant lifespan extension in either males or females in pooled data from three testing sites
What the research says
1 studyThe study tested nicotinamide riboside in the same type of mice (UM-HET3) mentioned in the claim and found it did not make the mice live longer. This matches what the claim says about no significant lifespan extension.
