Prof Shungu used 1800g of NAC in his small trial. Is that what you take?
I read somewhere that taking NAC is better than glutathione because it's much less likely to get destroyed in the gut. Dunno if that's right. I guess that's why
your husband takes liposomal glutathione? Does it protect it and deliver it safely?
It is best to do this in the care of a competent doctor based on labwork and take what's right for you and not be not trying follow what someone else does, which could lead you into trouble.
Theoretically, you want your entire methylation process works correctly - with the proper amounts of folate, B12, B6, B2, B3, potassium and magnesiumor you, along with adequate amounts of glycine, glutamine, and cysteine to make glutathione. And it helps to recycle glutathione, too. Glutathione doesn't stick around for long - it gets used up, so you need to keep all of this going.
If you make it and recycle it properly, then you won't need to take any. Shortcutting the process leaves you vulnerable to the effects of deficiencies in the above nutrients, which have other important jobs to do, like making blood, replicating DNA, keeping your heart beating, and maintaining cell membrane integrity.
I keep a bottle of Thorne glutathione in my purse and take it when I feel I need it, and it helps. It's not liposomal but I feel it working. Of course, the IVs and liposomal have their place, too.
