Turmeric and its phytonutrients, like curcumin, have been shown to support lowering of lipid peroxidation by maintaining the activity of antioxidant enzymes, such as superoxide dismutase, catalase and glutathione peroxidase, at higher levels.1 In animal studies, curcumin was reported to decrease the release of reactive oxygen species from macrophages and inhibit histamine release from mast cells.2 The chemical structure of the curcumin molecule allows it to have a significant effect on oxidative stress and immune-mediated reactions.13 However, several findings indicate that antioxidant and protective effects are synergistically enhanced when other turmeric components are included.21 Other turmeric components, such as turmerones,5,21 curdione,10,22,23 curcumol,7 cyclocurcumin,8,9 turmerin6,24 and β-elemene,11,12,25 all have significant impact on immune health and maintaining normal inflammatory balance.
A complete turmeric matrix was tested for its impact on immune cells. The test results showed it had a three-fold increase in phagocytic ability.17 Due to its pleiotropic effects and ability to pursue multiple inflammatory targets, turmeric has proven uses as an immune-boosting agent. A meta-analysis of eight randomized, controlled trials indicated that doses of 1,000 mg of curcumin per day were effective in balancing overactive immune challenges.19 In a randomized, double-blind, placebo-controlled clinical trial published in the Journal of Medicinal Food, a total of 36 patients with immune challenges were included to test out the efficacy of a complete turmeric matrix. A dose of 250 mg or 500 mg of the turmeric product was given twice a day to the patients in the treatment groups. Specific objective measures and lab markers were used to assess the response of these patients. The results indicated that a complete turmeric formulation improved objective measurements and maintained normal inflammatory balance.18 (See Figure: 1)
