The Claim
Nicotinamide riboside (NR) supplementation at tested doses did not significantly extend lifespan in genetically heterogeneous mice, with results consistent across three independent testing sites over a 5-year study period.
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.
A popular anti-aging supplement called nicotinamide riboside (NR) was given to mice to see if it could help them live longer, but the study found it didn't extend their lifespan at the doses tested.
See the scientific wording
Nicotinamide riboside (NR), a supplement marketed to boost NAD+ levels and combat aging, showed no significant lifespan extension in genetically heterogeneous mice at tested doses, with results consistent across three independent testing sites over 5 years.
What the research says
2 studiesThe study gave nicotinamide riboside (NR) to genetically diverse mice and found it did not make them live longer. This matches exactly what the claim says about NR not extending lifespan in these mice.
The study gave nicotinamide riboside (NR) to genetically mixed mice and found it did NOT make them live longer. This matches exactly what the claim says - that NR didn't extend lifespan in these types of mice.
