Multi Pro 32X from AST is a specialty multivitamin for male or female athletes and weight trainers who probably won't get everything they want or need in one-size-fits-all multi. Instead, athletes are better off going with a multivitamin formulated for athletes' special nutritional needs for antioxidants and other nutrients. But most sports multis are complex multi-capsule formulas like the Animal Pak, which require a handful of capsules and tablets for each dose. There's nothing wrong with that but some people just aren't comfortable taking that many tablets on a daily basis. And when you look around and compare one-per-day sports multis, you find there aren't too many good formulas. AST's Multi Pro 32X is one of the few, and about your best bet for a one-per-day sports multi. Since Multi Pro 32 X contains iron, it's better for women and younger men. Older men and women - most of whom don't need supplemental iron - might be better off with an iron-free multi.
