Glutathione Usage

Written by FoundHealth.

Therapeutic Uses

Various websites promote glutathione for a wide variety of health problems, from preventing aging to enhancing sports performance. However, oral glutathione supplements are almost certainly useless for any condition since they are not absorbed.

There is a bit of evidence that injected glutathione might offer a few heath benefits, such as preventing blood clots during surgery, 1 reducing the side effects and increasing the effectiveness of cancer chemotherapy drugs such as cisplatin, 2 3 treating male infertility , 4 5 6 7 and alleviating symptoms of early Parkinson’s disease . 8 Although oral glutathione is not likely to provide the same benefits, it is at least theoretically possible that taking the nutrients described in the previous section (and thereby raising glutathione levels indirectly) could offer similar benefits. However, there is no direct evidence to indicate that this hypothesis is true.
