The reason you have heard that it is used to help muscles better process carbs AND protect your liver is because it does both. In fact, it does so many things it's truly the most important supplement you'll ever use. Here is a short list of things it'll do for you. You should be using Tyler Liver detox with it for liver protection.
Liver cell regeneration
Improved Brain function and slows aging process
Regenerates all other anti-oxidants so they are effective longer
Inhibits cancer activation and proliferation
Slows skin aging process
Glucose uptake enhancement
Improves fat burning processes
Protects the retina of your eyes from eye diseases
Protects your heart and slows aging process
