It’s supposed to be helpful (some claim essential) for people on statins, as statins interfere with the body’s synthesis of COQ10. I’ve also heard from a few people (non-statin-users) taking it that it helped a lot with energy as they aged. It’s involved with mitochondrial respiration and also operates as an antioxidant. Maybe someone here has personal experience with it. I’ve only heard positives. Uniquinol is supposed to be the easiest form to utilize.
