I’ve purchased the glutathione for myself and 2 family members. We have some pretty intensive health concerns we’re trying to solve, so the jury is still out on how well it’s working, but we do see some positive changes. My brother who suffers from Parkinson’s can now sleep through the night. This is actually pretty huge. I myself and one other sibling are seeing our gray hair disappear. This is also huge and is helping make them believers.
