Keeping hydrated crucial

Healthcare
Experts back away from annual PSA test
New American Urological Association guidelines offer PSA testing to well-informed men aged 40 and older with a 10-year life expectancy, drop the fixed blood-level cutoff and weigh family history. False or inconsistent results can lead to surgery risking impotence and incontinence.

A NaturalNews report says ubiquinol, the reduced form of CoQ10, absorbs better than ubiquinone. Texas researchers who could not maintain adequate blood plasma CoQ10 on high doses of the unreduced form saw levels rise 22 to 39 percent once patients were given ubiquinol.
