I had a problem for years of my legs suddenly giving out for no apparent reason. I literally fell a thousand times over several years, including several bad falls on my face on concrete. Turns out my liver was not making enough Glutathione, a substance that is involved in many bodily functions, including muscle strength. (Liver function can be damaged by hundreds of poisons in the environment, and by poor diet. Most people suffer some liver damage.). Doctors had no clue, even multiple neurologists. I did years of research on my own. The solution was to take milk thistle (inexpensive, available in powder or capsules). It fixed my liver, and now I only have to take a capsule 2-3 times a week to keep my Glutathione up. You can take Glutathione itself, but it is expensive, and you need to take quite a lot of it, regularly. Better to fix your liver with Milk Thistle and give it necessary nutrients with a good diet with lots of green veggies. Milk Thistle is safe with no negative side effects.
