Glutathione is very important for the immune system, especially if you have mthfr. It is not easy to absorb and I'm trying the sublingual hoping it works. NAC upset my stomach.

We are not aware of clinical evidence showing that gluathione supplementation (i.e., taken by mouth) will help with any medical condition. If you know of a study that has shown a benefit, please let us know so we can review it. Thank you.
