I have heard of the whitening thing before!

does anything since it can't be destroyed in the stomach

Right, the IV works for whitening and it does have some health benefits but it only helps while you are using it and it doesn't work as well as NAC and Glycine for getting your body to produce its own glutathione properly again.

I don't know if it does anything since it can't be destroyed in the stomach.

Right, you definitely need to go with NAC and Glycine for rebuilding the glutathione stores properly. It shouldn't affect your skin color when done this way! But seriously, give it a try. It has really helped me and a lot of others. Another thing that some people get who have severe symptoms is sub-clinical Thiamin deficiency. Your levels show up normal, but your stores are low. This didn't really help me, but I've heard a lot of people get benefits by mega dosing it. It's called TTFD. You can find lots of info on it online. But I bet just with the NAC and Glycine you'd see a big difference. Also, creatine, believe it or not, is not just for building muscles. That same doctor I sent you a video about talks about it all the time. It has become hot in the health and longevity scene.
