Injectable glutathione

This would make more sense as a route of administration for glutathione. The human stomach digests glutathione into its component amino acids so its activity if taken orally is doubtful. However, the injectable prepartation is more expensive. The other alternative is the sublingual glutathione pills since glutathione is small enough to be absorbed thru the epithellium of the oral cavity. Some people open up the capsule form and pour the contents beneath the tongue.

It isn't harmful at all, I've asked my dermatologist about it. Cancer patients in Europe are treated with injectible glutathione since this is faster than the oral pills. THe side-effect of whitening is faster achieved thru this.
