Question 1

What is glutathione?

Accepted Answer

A tripeptide of glutamate, cysteine and glycine. It is the main intracellular thiol antioxidant and sets the redox environment inside cells.

Question 2

What does the GSH/GSSG ratio mean?

Accepted Answer

It compares reduced glutathione with its oxidised dimer, and is the standard readout for how oxidising conditions inside a cell have become.

Question 3

Why does it need handling care?

Accepted Answer

The free thiol oxidises in air and in solution, so a solution left standing contains progressively more of the dimer and less of the active form.

Question 4

Does oral glutathione work?

Accepted Answer

Its oral bioavailability is poor and that limitation is well documented, which is why cysteine precursors are often studied instead.

Question 5

What about injectable skin lightening?

Accepted Answer

That use is not approved and has been the subject of explicit regulator warnings, including from the Philippine FDA.

Question 6

What documentation comes with it?

Accepted Answer

A batch certificate of analysis with HPLC purity, linked on this page and verifiable on the testing laboratory's site.
