The Claim

Supplementation with glutathione and L-citrulline for 8 weeks has no adverse effect on clinical blood markers in resistance-trained males.

Source: 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

Description
1 study reviewed
In plain English

Taking glutathione and L-citrulline supplements for 8 weeks does not change clinical blood markers in men who train with weights, indicating no detectable toxicity at this dose and duration.

See the scientific wording

Supplementation with glutathione and L-citrulline for 8 weeks does not adversely affect clinical blood markers in resistance-trained males, indicating no detectable toxicity at the studied dose.

Why this might work

L-citrulline is converted into arginine, which the body uses to make nitric oxide. Glutathione protects nitric oxide from breaking down too quickly and helps it last longer. This allows nitric oxide to activate a signaling pathway that improves blood flow and muscle function, but does not overload or damage the liver, kidneys, or other organs.

  1. Study: 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

    This study gave trained men daily pills with glutathione and L-citrulline for 8 weeks and checked their blood before and after. Their blood tests showed no signs of harm to the liver, kidneys, or other organs, meaning the supplements didn't hurt them.
