It sounds to me like these guys are demanding citations for double-blind
human trials of antioxidants in diving.

The way I learned it, somewhere, such a trial would involve several groups
of divers, all in comparable physical condition, including a control group.
 The control group gets no antioxidants at all, the other group gets
varying doses of varying things.  The real test comes when you start diving
them; you have to first find the depth and oxygen exposure that puts 50% of
the control group into O2 tox convulsions, and hope you don't kill anyone
in the process, and then you run the other groups through the same exposure
and count the number of divers who convulse.

Medical research ethics suggests that we are probably not going to do this
experiment any time soon.
