Yeah I have heard that whey protein boosts gluathione levels really well. This can be helpful in eliminating toxins of all kinds, whether pathogen related or metals. problem is, metals usually need more than that, they usually require an agent that has two thiol groups to grip onto it strongly enough to escort it out.

That was my experience. Though raising glutathione is helpful anytime you're toxic or unwell. It's gets heavily depleted in these situations, viral, toxic, pathogen.

Vitamin C, selenium, milk thistle, NAC, whey protein, etc, all aid glutathione. Sometimes they cause too many reactions by doing this, so you should always start low at first in case you get too much of a healing / detox response.
