Ubiquinol Is Naturally Produced in the Body

Although Ubiquinol is naturally produced in your body, many people can benefit from taking a Ubiquinol supplement. There are two predominant forms of CoQ10 which occur naturally in the body: Ubiquinol (the reduced form of CoQ10) and Ubiquinone (the oxidized form of CoQ10). While both the Ubiquinol and Ubiquinone forms of CoQ10 play important roles in cellular energy production and other processes, our bodies need to convert Ubiquinone into Ubiquinol so it can perform certain vital functions. For example, in order for CoQ10 to confer antioxidant protection, it must be in the Ubiquinol form. However, as we age, it becomes harder for our bodies to convert Ubiquinone into Ubiquinol. That’s where Ubiquinol supplements come in. Taking a Ubiquinol supplement bypasses the need for conversion and helps to replenish Ubiquinol levels more efficiently, which is especially important for those who are over 40 or taking a statin.1,2,3

Is Ubiquinol Safe to Take While Pregnant?

There are no adequate and well-controlled clinical trials demonstrating that Ubiquinol supplements are safe to take during pregnancy. There is also no existing evidence that Ubiquinol is unsafe during pregnancy. Talk to your doctor before using Ubiquinol if you are pregnant or planning to become pregnant.

A typical daily dosage of Ubiquinol is 100mg per day, which is the amount generally recommended on supplement labels.

Can You Take Ubiquinol Daily?

Yes! There are several benefits to taking a Ubiquinol supplement daily. In addition to the aforementioned benefits of taking a Ubiquinol supplement, once daily Ubiquinol can replenish CoQ10 blood levels depleted by statin cholesterol medicines.3 Ubiquinol is also a powerful lipid-soluble antioxidant that helps neutralize free radicals.4 In fact, in a survey of primary care physicians who recommend CoQ10 to patients, Ubiquinol is the preferred form of CoQ10 for cardiovascular benefits and general health. For optimal absorption, take Ubiquinol with a meal.

In conclusion, Ubiquinol has been shown to be safe, and can offer substantial health benefits, particularly when taken regularly. If you are new to taking Ubiquinol, download our Beginner’s Guide for more helpful information.
