Coqsol-cf is a patent pending formulation of crystal-free coenzyme q10 solubilized in d-limonene oil. the formula also includes mixed tocopherols.coq10 is a nutrient that supports heart function and promotes energy production in cells. coq10 is a versatile antioxidant, which stabilizes cell membranes, protecting them from free radical damage. coq10 can also powerfully support immune function.coqsol-cf provides the well-known benefits of coenzyme q10 in a formula designed for enhanced bioavailability. coq10 is itself a highly unstable molecule that is prone to crystallization upon exposure to heat, light and air. many coq10 products are, therefore, highly crystallized. this crystallization process may decrease the absorption and bioavailability of the coq10. coqsol-cf solves this problem by providing crystal-free coq10 that is highly soluble and has enhanced bioavailability. coqsol-cf also provides the added antioxidant protection of mixed tocopherols. the end result of using coqsol-cf is that more of the coq10 is actually available for use by the body in performing its critical functions.
