Answer:
Glutathione may be referred to as natural glutathione, reduced glutathione, L-glutathione, oral glutathione, or glutathione pills. These are all referring to the same product.
If you take any of these products, the glutathione is destroyed in the gut and does not raise your glutathione levels in your cells, where you need it. You must make glutathione in your cells with the building blocks that are necessary for production.
The best ways to raise glutathione are with variants of cysteine. I base this on the amount of research that has been done on them. One well studied method for raising glutathione is with the pharmaceutical drug N-acetyl-cysteine, or NAC.
NAC is not recommended for infants, children, and pregnant and nursing mothers, and has potentially toxic side effects.

The other well researched method for raising glutathione is with bonded cysteine, such as is found in Immunocal.
