The effect of lifelong oral supplementation with ubiquinone Q10 (10 mg/kg/day) was examined in Sprague‐Dawley rats and C57/B17 mice. There were no significant differences in survival or life‐span found in either rats or mice. Histopathologic examination of different rat tissues showed no differences between the groups. In Q10 supplemented rats, plasma and liver Q10 levels were 2.6 to 8.4 times higher at all age points than in control rats. Interestingly, in supplemented rats the Q9 levels also were significantly higher (p<0.05) in plasma and liver at ages 18 and 24 months. Neither Q9 nor Q10 levels were affected by supplementation in kidney, heart, or brain tissues. In spite of the significant changes in plasma and liver ubiquinone concentrations, lifelong Q10 supplementation did not prolong or shorten the lifespan of either rats or mice.
