Garlic has been valued for centuries for its multi-faceted benefits. It has antioxidant action and can boost the level of natural glutathione, an important cellular detoxifier. The compounds allicin, oligosulfides, A. ursinum and A. sativum found in garlic support healthy platelet function. Published studies demonstrate garlic’s immune-supporting properties and numerous other health benefits. Garlic is reported to stimulate immunity, including macrophage activity, natural killer cells, and LAK cells. It has also been shown to increase the production of IL-10 and to decrease the production of tumor necrosis factor-alpha (TNF-alpha), IL-1alpha, IL-2, IL-6, and T-cell interferon-gamma (IFN-gamma). Clinical studies show that as much as 5–10 grams of garlic extract is effective in enhancing human immune responses. Optimized Garlic capsules contain 10,000 ppm allicin potential, a key health-promoting component of non-aged garlic. In fact, studies have highlighted allicin’s involvement in immune response and oxidative stress.
