Eight Weeks Of Resistance Training In Conjunction With Glutathione And L-Citrulline Supplementation Increases Lean Mass And Has No Adverse Effects On Blood Clinical Safety Markers In Resistance-trained Males

Effect None
Values (g/dl). Mean and SEM. Placebo: before 15.3 ± 0.2, after 15.3 ± 0.2. Citrulline: before 15.1 ± 0.2, after 15.0 ± 0.1.

Body Types Trained
Notes for this study:
In this randomized, double-blind, placebo-controlled trial, 81 participants who were resistance-trained took 2 g of citrulline malate, 2 g citrulline with 200 mg of glutathione, or placebo for 8 weeks while participating in resistance training.

There wasn't a notable or statistically significant difference between the citrulline or placebo group for body mass, lean mass, fat mass, total body water, or bench/leg press strength. Blood panel also wasn't notably different. The citrulline glutathione group performed better in various respects, but we can't tell if it was due to synergy or just the effects of glutathione.
