Thanks for your information on glutathione and brain injury. My son and my nephew play college football. It is very scary to think about what trauma their heads (and bodies) are experiencing daily. I have found an oral supplement that works better than cream and is definately less expensive than doctor prescribed injections. My nephew just got a concussion last week during practice for Spring Football. He is experiencing memory loss now...I hope he will be OK. Thank you for this website also. My Mom suffers from Alzheimers.
