About ShiroQ

ShiroQ is a highly stable, water-soluble form of ubiquinol (the reduced version of Coenzyme Q10).

Until recently, ubiquinol was only available as an oil dispersion in soft gel form. A breakthrough in ubiquinol delivery, ShiroQ overcomes the formulating barriers of regular oil-based ubiquinol with these unique characteristics:

  • Highly stable, maintaining 99.8% of its ubiquinol content after three months when stored in a deoxygenated environment at 104° F and 94.6% of its ubiquinol content after three months when stored in room air at the same temperature.
  • Water-soluble, making it easily dispersible in water. Its enviable solubility is due to its extremely small particle size: a diameter no more than 100 nanometers when dispersed in water (compared with 5077 ±2252 nm and 7549 ±3508 nm for other water-soluble ubiquinol ingredients).
  • Versatile, being suitable for inclusion in beverages, foods, tablets, stick packs and capsules.

Mechanism of Action

CoQ10 supports heart health by dilating blood vessels (thus helping maintain blood pressure levels already within a healthy range), inhibiting LDL oxidation and supporting healthy blood viscosity.* CoQ10 transfers electrons within the mitochondrial oxidative respiratory chain and helps produces ATP, the body’s main energy currency.*


CoQ10 in both its forms (ubiquinone and ubiquinol) occurs naturally in the human body. Over 90% of the circulating CoQ10 in the body is in the reduced ubiquinol form.  A safety test of ubiquinol on human subjects found no adverse events or safety concerns.[1]
