Feel the Post-Workout Burn -- Less
"Feeling the burn" after a workout is really your body recovering from the stress and strain of exercise. It's a process that might get a boost from a new supplement.

And, in fact, there is already one animal study that shows
that, on it's own, elevated HSP may not make much of a difference at all. In
preliminary research presented at the ACSM conference in May, doctors from
Georgia State University in Atlanta used heat to increase production of HSP in
mice. While they clearly documented elevations in HSP, it did not appear to
protect the mice against exercise induced injury - or speed their recovery
Although the company who makes PrePair provided WebMD with
toxicity studies on mice showing the supplement was proven safe, and says
thousands of products sold have yielded no reports of adverse effects, Gotlin
believes this is not enough proof to offer a blanket guarantee of safety to all
fitness buffs who use it.
"I would need large-scale human trials before I would take
this supplement, or recommend it," says Gotlin.
Talbott is more certain of the safety aspect and says he would
recommend the product. However, he tells WebMD, "I'm just not sure if
raising heat shock proteins has been proven to make a significant difference in
our fitness activities."
