Glutathione is produced inside the human cells where the production rate is determined by Glutathione precursors such as the amino acid cysteine. As people grow older or through a Glutathione lacking diet, the levels of Glutathione drop and the ability of the body to detoxify free radicals decreases. You are advised to consume foods that have high Glutathione amino acid precursors such as raw fruits, vegetables and whey proteins. The faster and easier way to increase your Glutathione levels is through direct supplementing. Supplementing with OPTIMUM GLOW’s OPTI GLUTA, a high dose Glutathione blend in your body is a fantastic way to improve your skin, overall health and longevity potential.
