Check the clinical trial info in their website but you have to be very skeptical about what a vendor posts on their site. In general there are no govt. agengies looking over the supplement agency. I suggest calling the manufacturer and asking them to send you the link to the independent test / agency that conducted their research. If they don't/can't produce this info then move on....
I suggest using consumerlab.com with all my patients for an independent review of all supplements they may be considering.
In general, start with a well balanced diet, and pls. don't buy into the media/manufacturing hype: get good info at my site www.my-nutrition-coach.com or at my know-stroke.org blog
I don't doubt the safety. But you have not posted the exact wording of the research that proves the efficacy. Giving us URLs and expecting us to decipher scientific-speak is not helpfull. You still haven't shown where you can differentiate the drug from natural recovery. Just because a hospital uses it does not mean it works.
