This is ubiquinol, the reduced, active form of Coenzyme Q10. The body puts it to work right away without needing to convert it first. For that reason, it tends to absorb better than standard ubiquinone, a benefit many older adults look for. It supports cellular energy production and acts as a fat-soluble antioxidant inside cell membranes.
Take this supplement alongside a meal that contains fat to boost absorption. The right dose depends on the form you choose. Be cautious if you take warfarin. CoQ10 has a structure similar to vitamin K and can weaken the blood thinner's effect.
