Some literature shows there are higher levels of glutathione in centenarians than less aged mature people. Supposedly this correlates with their ability to achieve longevity compared to others. Do you subscribe to the significance of this? I’ve never tested my levels. Perhaps I should?

The question is do they have more glutathione production (diet includes building blocks of glutathione, etc) or do they have less glutathione usage (less oxidative stress, other available antioxidants in diet)?
In other words, is the lower glutathione in less healthy people a cause of poor health or an effect of poor health?
I’m going with the oxidative stress sweetspot angle. Get some oxidative stress (exercise, sunshine, metabolism) to stimulate production of defenses and resilience, but don’t get too much too quickly. Keep chronic inflammation low. And avoid nutritional deficiencies.

I have no idea if the glutathione blood test is accurate. Hard to find info on that. GGT might be the closest thing you can get to check glutathione status.
Marek Diagnostics has a Glutathione (LC/MS) test for $65 (plus $5 Labcorp fee).
That’s a lot less expensive than what LabCorp charges if it’s the same:
I understand a glutathione blood test exists, but do we know that it’s accurate? No one ever seems to mention it.
