The benefits of Optimal Liposomal Glutathione are almost endless and this antioxidant is essential in helping the immune system function at full capacity. Glutathione is an important antioxidant found in every cell in our bodies, providing protection from free radicals and peroxides. Imagine an apple that turns brown when left in the open air. When you apply lemon juice onto the flesh of the apple that deterioration will not occur. The antioxidants in the lemon juice protect the flesh of the apple, and prevent damage or degradation. Glutathione is like lemon juice for the body; it helps protect cells from oxidative damage and may help support immune health. Optimal Liposomal Glutathione by Seeking Health provides natural phosphatidylcholine and phosphatidylethanolamine from non-GMO sunflower oil - using only non-hydrogenated phospholipids. This product is made of natural ingredients including natural flavors - so the taste may differ from bottle to bottle or once it has been opened.
