Lower plasma glycine levels are independently associated with higher BMI and male gender, suggesting glycine is a marker of favorable metabolic health and its reduction is a risk factor for metabolic syndrome.
Low glycine levels are linked to higher BMI and male gender, and may indicate higher metabolic risk. While this paper doesn't prescribe a glycine supplement dose, it highlights glycine as a key marker of metabolic health. Maintaining healthy body weight helps preserve glycine levels, which may support metabolic function.
In a multivariable model... glycine was independently and inversely associated with BMI (regression coefficient −0.012; p < .0001). Also, men had significantly lower levels of glycine (regression coefficient −0.061; p = .0026).
Why this rating
Consistent inverse association across 6 studies, strong statistical significance.
