Q: I am considering taking 600 mg dry ubiquinol with a teaspoon of safflower or olive oil. Could ubiquinol promote the growth or spread of cancer cells?

A: Ubiquinol is also known as Coenzyme Q10, which is naturally made in the human body. It helps cells produce energy and acts as an antioxidant, which may in fact work to help prevent cancer. Here is some more information on ubiquinol from our Health Library. Antioxidants are not suggested during certain types of chemotherapy and radiation as it can decrease the effectiveness of the treatment.
There have been several ubiquinol studies exploring its role in cancer treatment. It has been shown to protect the heart from anthracycline-included cardiotoxicity during chemo and to stimulate the immune system. Analogs of Coenzyme Q10 have even been shown to inhibit the proliferation or growth of cancer cells in vitro and in rats. However, while the studies are limited, there has been promising results of its use as a protective agent.
Doses are highly variable ranging from 100 to 2000 mg depending on current health conditions. Standard doses are usually 100-200 mg. As you stated, ubiquinol should be taken with some fat to help improve absorption.
