X-Message-Number: 27665 From: "Billy H. Seidel" <> Subject: CoQ10 Date: Thu, 2 Mar 2006 16:03:01 -0800 These guys are from USC's toxicology lab and used huge doses (multi-gram equivalents). It's a wonder that the mice survived at all. Send the question to Steve Harris since it directly conflicts with his results. Steve used about 800 mg equivalent as I recall. I videotaped one of his CoQ10 rat studies and his results were amazing. Steve Harris can be found on the LifeExtension Web site, www.lifeextension.com. I also believe he is on cryonet. I am no expert but Steve Harris sure is. Billy H.

Epub 2005 Nov 9. Effect of coenzyme Q(10) intake on endogenous coenzyme Q content, mitochondrial electron transport chain, antioxidative defenses, and life span of mice. The main purpose of this study was to determine whether intake of coenzyme Q(10), which can potentially act as both an antioxidant and a prooxidant, has an impact on indicators of oxidative stress and the aging process. Mice were fed diets providing daily supplements of 0, 93, or 371 mg CoQ(10)/kg body weight, starting at 3.5 months of age. Effects on mitochondrial superoxide generation, activities of oxidoreductases, protein oxidative damage, glutathione redox state, and life span of male mice were determined. Amounts of CoQ(9) and CoQ(10), measured after 3.5 or 17.5 months of intake, in homogenates and mitochondria of liver, heart, kidney, skeletal muscle, and brain increased with the dosage and duration of CoQ(10) intake in all the tissues except brain. Activities of mitochondrial electron transport chain oxidoreductases, rates of mitochondrial O(2) generation, state 3 respiration, carbonyl content, glutathione redox state of tissues, and activities of superoxide dismutase, catalase, and glutathione peroxidase, determined at 19 or 25 months of age, were unaffected by CoQ(10) administration. Life span studies, conducted on 50 mice in each group, showed that CoQ(10) administration had no effect on mortality. Altogether, the results indicated that contrary to the historical view, supplemental intake of CoQ(10) elevates the endogenous content of both CoQ(9) and CoQ(10), but has no discernable effect on the main antioxidant defenses or prooxidant generation in most tissues, and has no impact on the life span of mice. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> end of copy <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< Content-Type: text/html; [ AUTOMATICALLY SKIPPING HTML ENCODING! ] Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=27665
