Fortunately, an effective way to boost thiamin pyrophosphate in your cells does exist: Benfotiamine (S-benzoylthiamine-O-
As a result, your body absorbs Benfotiamine better than thiamin itself, and levels of thiamin and TPP remain higher for longer. Thiamin absorption from Benfotiamine is about five times as great as from conventional thiamin supplements. And the effect is even more impressive at the tissue level: brain and muscle, for instance, take in five- to twentyfive-fold as much thiamin in the form of allithiamines as they do of an equal amount of regular thiamin. And Benfotiamine is even more bioavailable than the other allithiamines, including thiamin tetrahydrofurfuryl disulfide/TTFD. Yet Benfotiamine is actually less toxic than conventional thiamin supplements!
By effectively increasing levels of thiamin itself, Benfotiamine dramatically boosts AGE-fighting thiamin pyrophosphate and cell-shielding transketolase activity in your body.
