Is there a difference between l-glutathione & glutathione?
Are Glutathione and L-Glutathione chemically the same, or there is some difference? If yes, then what are the differences between these two?
They are the same thing - oral glutathione. Reduced glutathione is another term, and all three are the same thing. That means it is a pill taken orally, and it will not raise your glutathione levels in your cells, as they will be destroyed in your gut. Save your money.
