The present invention generally relates to improvements in the bioavailability and/or solubility of coenzyme Q10. For example, the present invention relates to methods for preparing particulate compositions including coenzyme Q10 that generally comprise dispersing and/or dissolving the coenzyme Q10 throughout a suitable solvent, and combining the coenzyme Q10 and an encapsulating (e.g., microencapsulating) agent. The present invention also generally relates to particulate compositions comprising coenzyme Q10 that exhibit improved bioavailability and/or solubility as compared to previous coenzyme Q10 products.
