The product itself works good, it gives me great energy, no caffeine let down and no jittery feeling. I don't pee bright yellow, which lets me know the vitamins are being absorbed by my body and not just flushed out. I did lose weight in the first 8 weeks, about 5 lbs, I have not continued to lose weight though. I'm 60 years old and in good health, I have noticed some relief in everyday pains and health issues (that come with age). My arthritis in my thumb seems less, as I said my energy is up, it seems to be having some slight cognitive effects on my memory and I'm sleeping much better. I don't feel or look 21 years old anymore and this vitamin system is not the fountain of youth. However, I do feel good and have less pain and more energy. I'm sure there are a lot of products out there that would do this, we all need vitamins. The bottom line is that this is a good product that meets my health needs.
