Older subjects had cysteine and glycine added to their diets to increase glutathione levels, which spiked within two weeks, improving insulin resistance and fat burning
heres the deeper dive
For example, a recent systematic review and meta-analysis of Ginkgo biloba in depressive patients reported overall efficacy on depression rating scales and related biomarkers but did not stratify outcomes by subtype such as post-stroke, postpartum, or depression comorbid with medical illness, nor was evidence on subtype-specific effects identified in the analyzed trials (103)
Waiting 15-20 minutes typically suffices for temperature equilibration
No changes in cysteine concentrations or GCL enzyme activity
However, human clinical evidence is still limited, and larger, well-controlled trials are needed to clarify safety, efficacy, and appropriate use
