Brief Summary:
The investigator proposes to perform a phase I/II study comparing two nutraceuticals and placebo that target mediators identified in the investigator's prior dynamic modeling study of Gulf War Illness (GWI). The investigator will repeat the dynamic modeling before treatment and on therapy to assess the modeling and the impact of the interventions on the homeostatic networks that have identified, with an added focus on the glutathione/redox system.

Condition or disease Intervention/treatment Phase
Gulf War Syndrome Drug: Curcumin Drug: Glutathione Other: Placebo Phase 1 Phase 2

Detailed Description:
In the Investigator's prior study "Dynamic Modeling in GWI", the investigator used an exercise stress model (rest, peak oxygen consumption oxygen uptake, and 7 follow-up sampling points) to measure the mediators of relapse in the context of their interactive homeostatic networks. The investigator surveyed the response of genes and blood-borne biomarkers in order to interrogate and map regulation of neuro-endocrine-autonomic-immune function in these subjects as compared to GW era sedentary healthy controls. The investigator's research team applied an integrative systems-based approach rooted in computational biology connecting gene expression and biomarkers to pathways and to symptoms in order to identify potential therapeutic targets as well as optimal strategies for manipulation of these targets. Using this data the investigator's research team has developed a virtual model of the illness, which has been used to identify potential therapeutic targets.

Arm Intervention/treatment
Experimental: Curcumin
12 weeks 400mg orally twice a day
Drug: Curcumin
Perform a randomized phase I/II study comparing curcumin (increased bioavailable form, body cell mass-85, 400 mg twice a day) to glutathione (liposomal bioavailable form 630 mg bid), with a 3 month intervention and assessment of safety, efficacy and biomarker response to therapy.

Experimental: Liposomal Glutathione
12 weeks 630mg orally twice a day
Drug: Glutathione
Perform dynamic modeling studies before and after 3 months of therapy, repeating the method used previously in order to compare the response to exercise across groups and better quantify the degree of recovery in treated subjects using an exercise challenge and 9 point in time blood and saliva collections over 24 hours with genomic, cytokine, neuropeptide and cell population studies.

Experimental: Placebo Liquid or Capsules

Placebo liquid for Glutathione 120 ml per/ bottle 420 mg/5 ml

Placebo capsules for Curcumin 60 capsules per bottle 400 mg /cap

Other: Placebo

Placebo liquid 120 ml per/ bottle

Placebo capsules 60 capsules per bottle 400 mg /cap

With the addition of a Partner PI, redox/methylation expert Dr. Richard Deth, perform studies of antioxidant and methylation-related metabolic status prior to, during and after acute exercise in GWI subjects before and after interventions.

Primary Outcome Measures :
  1. Biomarker response to therapy using a VO2 exercise test [ Time Frame: 12 weeks ]
    Goal is that both will prove safe for use in GWI patients

  2. Biomarker response to therapy using cytokine panel [ Time Frame: 12 weeks ]
    Goal is that both will prove safe for use in GWI patients
