I have more energy now than I did when I started taking Energy Renew, but am still not back to the level I had before (I had anemia last year). I'm not sure if your product has helped, but I will continue to take it. One concern I have came from a friend I told about the product. She found an article in WebMD that indicated the needed dose of r-ribose was 60 grams per day, and your product only contains 5 grams. I would not recommend the product as of now; I need to take it a bit longer to be sure.
Bottom Line: No, I would not recommend this to a friend
