I've been quite skeptical about this product and organization, however after reviewing their information a third time I decided to give their product a try. After only three days use I noticed a difference. I didn't want to say anything one way or another as it was still too soon. Three weeks later and I'm still happy with the improved results that I'm experiencing. I now have much greater use of my arms and hands as opposed to prior to taking the daily supplements. Now if I could just get my right leg to follow suit. I have a lot of leg dyskinesia going on again recently.

Using your body as a lab experiment based on an advertisement is risk. The supplement says it contains "7 RESEARCH SUPPORTED INGREDIENTS"

I looked up research on one of those products, N-acetylcysteine (NAC)

The results don't seem promising

"We showed that when individuals take 3000mg of NAC twice daily over 4 weeks there are significant increases in blood glutathione.
"We were also able to measure brain glutathione levels in this study using MRS. Although there was an increase in the levels of brain glutathione after 4 weeks of NAC, the increase was not significant.
"This highlighted that oral NAC is not as effective at changing blood or brain antioxidant levels as an injectable form of NAC we have previously studied.
"We also found that whilst most participants tolerated the dose of oral NAC well, some stopped taking the supplement due to concerns that their Parkinson's symptoms had worsened.
"After they stopped taking NAC, these participants quickly felt better and stated they were back to how they were before the study started."

Update. After using the product as directed my body odor began to change for the worse in three months time and the effectiveness wore off. I had to stop using the product altogether. Sorry, but that was my experience.

Thank you for the info. I hate those that prey on the sick. Karma..

I looked into Restore Gold, too. This is what I found:

Their ads look slick and are filled with people who look like doctors... but their address is a "mail drop."
When I asked for the names of medical professionals, they wouldn't give me any.

This looks to me like a way to make a quick buck off PD patients.
