I cannot be sure if or if it doesn't really work. Even though Dr. Joe McCord, recipient of Elliot Cresson Award, has been with the board until 2013. The reason is I have bought as many as 50 bottles, even 20 of Canine Health and no one could tell me, including LifeVantage's main office in Utah, on how to get tested to see that in fact, my glutathione levels were increased at all. So if only animal subjects tested, how can those claims be made? I need answers or I'll think it's been a scam for all the money I spent, as I do a significant amount of research, especially with dogs, and not even Rodney Habib, the most intelligent blogger for DOGS, ever mentioned Protandim or Canine Health and he is remarkable, better than 50% of US veterinarians. He may not be a licensed vet but he sure knows a heck of a lot more than most of them about canine health, and couldn't recommend this product to anyone, as if there's no way for me to know. And it was 2.5 yrs ago, and I'll say this again, buying around 50 bottles at least, yet I couldn't get facts with my own bloodwork. Period or question?
Bottom Line: No, I would not recommend this to a friend
