What it is
Three amino acids, with the cysteine supplying the working part: a sulphur group able to give up electrons. It mops up reactive particles before they do damage.
How it works
By oxidising instead of something else. Two oxidised molecules couple to each other and are afterwards separated again by an enzyme. The ratio between the two forms is a widely used measure of oxidative stress in a cell.
What the research shows
Its role inside the cell is very well described. Giving it from outside is another matter: the molecule does not easily enter cells, which is why much research focuses on precursors rather than on glutathione itself.
Research status
Clinically used in certain poisonings; a research compound for the broader uses.
Practical
The sulphur group oxidises easily, so this preparation is sensitive to air and light. Close it well, store dark and prepare fresh.
