(57) [Summary] [Problem] Coenzyme Q is poorly water-soluble and highly crystalline, so that it is poor in dispersibility in water and poor in bioabsorbability. 10, separation, sedimentation, flocculation, stably be dispersed in water without causing crystallization and the like, yet provide the coenzyme Q 10 containing compositions which can be well absorbed in the living body. With A coenzyme Q 10, L-glutamine content is at least 15 wt%, average molecular weight of 20 Coenzyme Q 10-containing composition containing the peptide is 0～100,000. |
