Glutathione levels: a six-month oral placebo study

Evidence level: Human randomized study; oral formulation

Research question

Does long-term oral glutathione supplementation change the amount of glutathione in the blood and certain cells?

Study design

In a randomized, double-blind, placebo-controlled study, 54 nonsmoking adults were followed for six months. The researchers measured glutathione in various biological samples.

What was found?

The authors reported increases in glutathione stores in the compartments examined. The article therefore concerns measured substance concentrations, not proven prevention or treatment of diseases.

Limitations and interpretation

The oral formulation used and the healthy participants limit the applicability of the results. The findings are not evidence for another route of administration or for the Peptidera research product.
