hi there! been off line for a couple days. of course it's fine to post questions here

glad you are finding the info useful.
zinc has important structural roles (eg protein folding - see prion diseases for examples of what can go wrong with improper protein folding), influences genetic expression (especially in tissues with high cell turnover, such as the liver), and is key (obviously) for the proper function of any zinc-dependent enzyme (there are over a hundred if you read some sources, over 300 if you read others). as for zinc and regulatory t-cells:
Zinc deficiency in Mexican American children: influence of zinc and other micronutrients on T cells, cytokines, and antiinflammatory plasma proteins
http://ajcn.nutrition.org/content/88/4/1067.short"Results:Before treatment the mean ± SD plasma zinc was 14.9 ± 1.7 μmol/dL and the range was within the reference; hair zinc was 1.78 ± 0.52 μmol/g and 41.6% were ≤1.68 μmol/g; serum ferritin was 25.7 ± 18.6 μg/L and 50.0% were ≤20 μg/L. The zinc and micronutrients treatment increased the lymphocyte ratios of CD4+ to CD8+ and of CD4+CD45RA+ to CD4+CD45RO+, increased the ex vivo generation of interleukin-2 (IL-2) and interferon-γ (IFN-γ), decreased the generation of interleukin-10 (IL-10), and increased plasma interleukin-1 receptor antagonist (sIL-1ra) and soluble tumor necrosis factor receptor 1 (sTNF-R1). Micronutrients alone increased the ratio of CD4+ to CD8+ but not of CD4+CD45RA+ to CD4+CD45RO+, increased IFN-γ but had no effect on IL-2 or IL-10, and increased sIL-1ra but not sTNF-R1. Efficacy of zinc and micronutrients was greater than micronutrients alone for all indexes except the ratio of CD4+ to CD8+, which was affected similarly."
as for glutathione, zinc and selenium both help your body naturally increase glutathione levels. read more here:
natural-approach-f27/topic18850-15.html#p192831resveratrol and curcumin will have a band aid effect on a single target, meanhwile ensuring optimal nutrient levels should have broad spectrum benefits for multiple health targets. my two cents. i don't see why sticking a band aid on a broken system would be preferable to fixing the system.
my naturopath is gung ho about castor oil packs for leaky gut among other things, and also promotes a gluten free diet, but ime zinc is at the root of both probs. research zinc and intestinal permeability. zinc levels before and after gluten free diet. the research is all there.
anyway, i might not answer right away but ya feel free to ask away whenever something comes up
