Hello, my doc has recommended a product called Ultrathione, an oral glutathione formula that allegedly is far superior than regular GSH capsules. It's not very clear to me in which way it should be a better product but it certainly is more expensive This is their "scientific" page: http://www.glutathionescience.com/physician and scientist information on the ultrathione 1.pdf Of course there doesn't seem to be any independent validations and the claims are pretty generic. They are basically saying... we have created a secret recipe for an highly absorbable glutathione. Trust us. Here's another website talking about the product. http://www.matteodallosso.org/eng/?page_id=43 Comments? Experiences?
