Ubiquinone and ubiquinol are two forms of CoQ10 used in supplements. Ubiquinone is the oxidized form; ubiquinol is the reduced form. Products vary by form, dosage, format and other ingredients.
Ubiquinol, the reduced form of CoQ10, is generally more expensive to produce than ubiquinone, one of the bigger price differentiators. Softgel vs capsule format and overall potency also contribute.
CoQ10 supplements are available in softgels, capsules, chewables, gummies and liquid formulations. Product availability varies by brand.
Some CoQ10 supplements are formulated with additional antioxidants such as vitamin E, while others contain CoQ10 alone. Combination formulas are one of several formulation options.
