This ultra low energy monosacchride D-Psicose (A mere .3% of the energy of sucrose by weight) has been implicated in humans for reducing the glycemic load of carbohydrate consumption.

This could have significant metabolic syndrome implications, as well as potential use for offsetting the very high glycemic loads imposed by various protein and mass gainer products while keeping cost low (It's a really chap ingredient) or even in fat burners.

I haven't seen any company selling it, except for one GRAS exemption application by one company several years ago who doesn't seem to have actually marketed it.

Any company people on here looked into the ingredient or considered using it?
