When we are young our body produces lots of CoQ10. As we grow older, we produce less and less of it. Coq10 is another anti-oxidant and works even more efficiently when combined with PQQ. CoQ10 has another very important function, it increases energy transfer capabilities which aids in the efficiency of the mitochondria processing. CoQ10 comes in two forms – Ubiquinone and Ubiquinol. Ubiquinone has to be converted by the body into Ubiquinol in order for it to use it properly. As we get older the body becomes less efficient in making the conversion. Q5 uses only the already converted Ubiquinol form which is readily absorbed and used by the body immediately without any need for conversion. It is the reason that Q5’s Ubiquinol CoQ10 is up to 8 times more effective than the more common Ubiquinone form of CoQ10.
