As most people get older and our metabolism in our bodies change and our cells produce less Glutathione. Researchers discovered that older individuals have lower levels of Glutathione and were found to have less fat burning ability and a higher rate of fat storage in the body because of this.
These same studies are showing that increasing your level of Glutathione in your cells will greatly improve insulin resistance and fat burning ability.
I have found that taking a daily supplement that will give your body the ingredients it needs to create Glutathione NATURALLY is the best alternative. I find products that contain RiboCeine work the best.
