IV Glutathione therapy actually quite expensive - not to mention invasive - what is needed is creating the environment for one's own body to produce this master anti-oxident - which we all did in our early youth - but due to our industrialized, fast paced lifestyle, extended life span - many natural avenues of basic health maintenance are being reduced or removed all together. I am a simple housewife, caregiving my Parkinson husband, and have been using a regime as one prong that is helping my husband alot. He is in his eight year with PD, and is in better condition now than he was over a year ago. Almost a miracle. If anyone is interested in contacting me - please do so at rozmund@gmail.com - I will be happy to forward links and Word articles to help out. All we know that since we have both been on this new protocol, I have given bottles and bottles of suppliments away to others in order not to see them wasted...as we simply only need our present methods. I sell nothing directly...check it out....the way we are all going, we stand to live until age 90 and preventative measures will be key -to keep our quality of life and keep us at home out of the nursing home scenario - for both emotional and economic reasons. Control of one's health is key. Knowledge for that control is available. We do not have to be professionals...just informed and pointed in the right direction.
