An exploration of what happens to mice when they are given diets with low or high concentrations of coenzyme Q10 paints a rather different picture than that anticipated. Diets low in the coenzyme did not affect age related deterioration in muscle strength, balance, coordination, learning, or memory. But diets high in the coenzyme led to worse age related losses in auditory acuity and impaired spatial learning and memory in old mice (Journal of Nutrition 2009;139:1926-32, doi:10.3945/jn.109.110437).
