The present invention provides a reduced coenzyme Q 10 crystal with excellent stability and a composition containing said reduced coenzyme Q 10 crystals. n According to the present invention, after dissolving reduced coenzyme Q 10 in a fat and oil, it is cooled, making it possible to obtain reduced coenzyme Q 10 crystals with excellent stability and which exhibit an x-ray diffraction pattern (using a CuKα emission line) that differs from ordinary reduced coenzyme Q 10 crystals. Moreover, said crystals are also excellent in bioabsorbability. |
