Quick Facts

Reference Sizes
30 mg, 50 mg, 60 mg, 100 mg, 200 mg, 300 mg, 400 mg
Storage
Store tightly closed away from heat light and moisture; follow product labeling for liquid formulations
Solubility
Highly lipophilic and poorly water-soluble; lipid dispersion and formulation strongly affect bioavailability

Catalog Description

Coenzyme Q10 is an endogenous lipophilic electron carrier in mitochondrial respiration and an antioxidant in reduced form. Oral absorption is formulation-dependent and generally improves with lipid-based preparations and food. Ubiquinol is not universally superior to every well-dispersed ubiquinone formulation.

Catalog descriptions reflect research context only. Not a medical claim or treatment recommendation.
