What about reduced glutathione suppositories?
Do they work to effectively raise the glutathione level? I am looking at Zetpil Reduced Glutathione Suppositories.
This was a new one for me, I had never heard of this before. Thanks for asking about it!
I looked on the web for more information on this product, and it appears that Reduced Glutathione is used in conjunction with N-Acetyl Cysteine to raise glutathione in suppository tablets.
Will these raise your glutathione level? I can't say for sure. If and when the studies come out on this product, we will know for sure.
Here's why: N-Acetyl Cysteine alone has been proven in medical studies to raise glutathione. You don't have to go to this extreme to get N-Acetyl Cysteine, you can get it at the local health food store for much less money. It costs pennies to make. At $91 a bag, this supplement is more expensive than Immunocal on autoship.
If this product was tested and shown to raise glutathione, how would you know if the results were from the N-acetyl cysteine alone, or from both ingredients? There would be no way to know what effect the glutathione had on the cells when administered this way.
This particular product does not have published results on Pubmed, but a search there brought up a few results indicating that glutathione administered this way may indeed raise glutathione values all by itself in laboratory rats.
Immunocal is the most effective, safe, and natural way to raise and sustain your glutathione.
You can order Immunocal here.
