Hi everyone I would like to know which supplement to take to boost cellular glutathione levels, having them low is causing breathing problems similar to asthma
You can actually take glutathione as a supplement. Like @Stevesmi said, you can take it by itself or it's found in a lot of supplement blends like the health/detox product n2guard from n2bm.com
The best supplement to raise glutathione levels in the body is a good quality whey protein isolate. Human breast milk is actually 80% whey protein.
Just do your research since all whey proteins are not created equal. This article will help explain what to look for when shopping for a whey protein - https://www.evolutionary.org/whey-protein-isolate/
Is this something your doctor has said is the issue? Seems like you can supplement and fix it on your own but I am just curious what a doctor said about it.
