The Claim
In female mice aged 12 to 24 months, 8% glycine supplementation is associated with a sustained 7%–10% reduction in body weight, while no significant weight change is observed in male mice under identical conditions.
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.
Female mice given 8% glycine in their diet lose 7% to 10% of their body weight between 12 and 24 months of age, while male mice given the same diet do not lose weight.
See the scientific wording
In female mice, 8% glycine supplementation is associated with a sustained 7%–10% reduction in body weight from 12 to 24 months of age, while no significant weight change occurs in males, indicating a sex-specific metabolic effect.
In female mice, high levels of glycine activate special channels on immune cells in the liver and lungs, making these cells less active. This reduces long-term inflammation, which changes how the body uses energy and burns fat, leading to lower body weight over time. Male mice do not show this effect because their immune cells respond differently to glycine.
What the research says
1 studyStudy: Glycine supplementation extends lifespan of male and female mice
Female mice that ate extra glycine stayed lighter as they aged, while male mice stayed the same weight — just like the claim said. The study proves this difference is real and lasts a long time.
