The Claim
In genetically heterogeneous mice, supplementation with aspirin (60 or 200 ppm), inulin (600 ppm), or TM5441 (60 ppm) initiated at 11 months of age has no significant effect on median or maximum lifespan.
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.
In a specific strain of mice, giving aspirin, inulin, or TM5441 starting at 11 months of age does not change how long the mice live on average or at their maximum lifespan.
See the scientific wording
In genetically heterogeneous mice, supplementation with aspirin (60 or 200 ppm), inulin (600 ppm), or TM5441 (60 ppm) from 11 months of age shows no significant effect on median or maximum lifespan, indicating these interventions do not extend longevity in this model.
When glycine levels rise, it enters immune cells in the lungs and liver and opens special channels that let chloride ions flow in. This makes the inside of the cells more electrically negative, which stops the cells from becoming activated and releasing inflammatory signals. Less inflammation in the lungs reduces the growth of cancer tumors, which allows mice to live longer. Aspirin, inulin, and TM5441 do not trigger this same process, so they do not extend lifespan.
What the research says
1 studyStudy: Glycine supplementation extends lifespan of male and female mice
Scientists tested three common supplements—aspirin, inulin, and TM5441—in older mice and found they didn’t make the mice live longer. This matches the claim that these supplements don’t extend life in this type of mouse.
