The Claim
In adults aged 75 and older, men have a higher intracellular water content per kilogram of lean mass than women, with a mean difference of approximately 19 mL/kg.
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 people aged 75 and older, men have about 19 milliliters more intracellular water per kilogram of lean body mass than women.
See the scientific wording
In adults aged 75 and older, intracellular water content per kilogram of lean mass is higher in men than in women, with a mean difference of approximately 19 mL/kg, suggesting sex-specific differences in cellular hydration that may contribute to disparities in muscle function and frailty risk.
Men have more water inside their muscle cells than women after age 75, which keeps the muscle's force-producing parts properly hydrated and working efficiently. This extra water also prevents the muscle from breaking down as quickly, helping men maintain stronger muscles and less frailty.
What the research says
1 studyThe study found that older men have about 19 mL/kg more water inside their muscle cells than older women, which may help explain why men often have stronger muscles and are less likely to become frail. This matches exactly what the claim says.
