"Accel Lifetime is the best all-around vitamin supplement. It has extra selenium which is what is needed up here in the North East. Also the higher doses of vitamin C and E are great as well. I just wish it would come in a pelleted form. It is very powdery and I've noticed because of that, it can be inhaled. (Wonder if that's good for the lungs?) Hmm, probably not. Other than that, I think it's the best out there for an all around supplement. The horses and ponies love the taste too!"
