The Claim
Calcium alpha-ketoglutarate (CaAKG) supplementation beginning at 18 months of age was associated with a 16.6% extension in median lifespan and a 19.7% extension in maximum lifespan (90th percentile mortality) in female C57BL/6 mice in the first cohort, and a 10.5% and 8% extension respectively in the second cohort.
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.
Giving female mice a supplement called calcium alpha-ketoglutarate starting in middle age helped them live longer - about 17% longer on average in one group and around 10% longer in another group, with the oldest mice also living longer.

Calcium alpha-ketoglutarate (CaAKG) supplementation starting at 18 months of age was associated with a 16.6% extension in median lifespan and 19.7% extension in maximum lifespan (90th percentile mortality) in female C57BL/6 mice in the first cohort, and a 10.5% and 8% extension respectively in the second cohort.
What the research says
1 studyThe study tested the same supplement (CaAKG) in the same type of mice (C57BL/6) as mentioned in the claim, and found that it does extend lifespan, supporting the main idea even if the exact percentage numbers from the claim aren't shown in this abstract.
