The Cur-caps from Theranaturals are pretty good I think. All of the people I have read about taking GSH get their's from Theranaturals. My son has been on them since the end of Nov., and has put on six kilos in weight. He also has more energy and rosy cheeks...it's such a pleasure to look at him and see a 'well' person! I really feel that the GSH has contributed significantly to his improvement in health.
He also started on Azithromycin at the same time, so this has also helped him heaps.
With regard to the curcumin etc., I just see it as a bonus supplement...I dont know if it helps much. The NAC is too small of a quantity to be of a great benefit, but it helps...I also have Sam on about 600mgs of NAC in addition to the 200-250mgs he gets fron the Cur-caps (he's 10). A lot of people use both.
