Previously, I've talked about Chlora's potential benefits for preserving the immune function of athletes

0:12.0

and improving some cardiovascular risk factors, such as dropping blood pressures by a few points,

0:17.0

or lowering LDL cholesterol about eight points.

It may help detoxify some dietary cholesterol, but what about the toxins found
