Hi KNPV,

When you read the article, did you click on the link to the blog post by Prof. Frank Church?

In particular, where he said the following:
"- Extracellular GSH cannot be transported easily into neurons, although there is evidence GSH gets past the blood brain barrier;
- N-acetyl Cysteine (NAC), is an anti-oxidant and a precursor to GSH. NAC gets through the blood brain barrier and can also be transported into neurons;"

He went on to say:
"On a personal note, I have been taking ... NAC ... for the past year with the hope that it is performing the task as outlined in this post."
