The raison d'etre of this website is to provide you with hard scientific information which may help you make informed decisions in your quest for health (so far I have blogged concise summaries of over 1,500 scientific studies and have had three books published).

My research is mainly focused on the effects of cholesterol, saturated fat and statin drugs on health. If you know anyone who is worried about their cholesterol levels and heart disease, or has been told to take statin drugs you could send them a link to this website, and to my statin or cholesterol or heart disease books.

Phosphocreatine is a substance that is fundamental to the ability of the body to produce muscular energy.

Elevated blood levels of creatine kinase are indicative of muscle damage.

The study investigated the association of statin treatment on recovery from exercise. The study included ten patients, (who were subject to a four-week regimen of statin therapy), who had their phosphocreatine and creatine kinase levels measured pre- and post-statin therapy.

The study found:
(a) Phosphocreatine levels took 97% longer to recover from exercise after statin therapy.
(b) Creatine kinase levels rose by 17.7% after statin therapy.

The results of the study suggest that statin therapy may impair energy production and promote muscle damage.
