Crystal-Free CoQ10 - 50mg

Proprietary Formula

Thorne Research Q-Best 50mg is a proprietary formula of crystal-free CoQ10 that is an essential nutrient for cellular energy production.


Q-Best is a proprietary, crystal-free preparation of coenzyme Q10 (aka ubiquinone) that consistently has demonstrated superior absorption over other forms of CoQ10, including dry powder, oil-based softgels, liposomes, micelles, and nanoparticle preparations.

All supplemental CoQ10 originates in a crystal (dry powder) form. However, this crystal form alone is not well absorbed because the crystals do not fully dissolve in the intestines and the body cannot absorb lipid crystals. When crystals are dissolved in a lipid-based delivery system (ie, oil-based softgels, liposomes, micelles, and nanoparticles), absorption is improved. However, there is still partial crystallization found in these preparations.


Exclusive crystal-free CoQ10 for superior absorption.


  • Proprietary formula with demonstrably better absorption over other CoQ10 forms, including dry powder, oil, nanoparticle, and liposomal preparations
  • Promotes normal cardiovascular function, enhances blood vessel function, and is an essential nutrient for cellular energy production
  • No chemical additives or titanium dioxide
  • Nearly three times better absorbed than ubiquinol

Q-Best provides CoQ10 in a fully dissolved, crystal-free, lipid-based form, allowing greater absorption by the intestinal mucosa. This is accomplished by a proprietary, tri-lipid delivery system. One lipid keeps the CoQ10 crystals fully dissolved at 10°C above body temperature; the second lipid keeps the CoQ10 crystals fully dissolved below body temperature; and the third lipid acts as a carrier molecule to facilitate absorption.

Clinical trials demonstrate superior absorption over dried powder preparations. In addition, a plasma CoQ10 bioavailability study observed absorption of Q-Best to be vastly greater than other forms of CoQ10, including oils suspension, nanoparticle, and liposomal preparations. This is why we believe Q-Best is the best CoQ10 formula available today.

Coenzyme Q10 functions as an intracellular antioxidant Due to its involvement in energy production within the cell, CoQ10 affects the function of all cells in the body, making it essential for the health of tissues and organs. CoQ10 particularly benefits the most metabolically active cells: heart, immune system, gingiva, and gastric mucosa. An adequate supply of intracellular CoQ10 is vital to the health of heart muscle. CoQ10 supports normal heart rhythm and can help maintain already normal blood pressure.
