Ubiquanol: I am unaware of any literature that progibits use of ubiquanol with thyroid medicine. If you are pregnant, congratulations, you still can take ubiquanol

Can=always an option. But does not mean wise/worth time, effort & money. Medicine=low-tech, humans extremely Hi-Tech. Many things long been promoted & sold are later found of no value &/or harmful. While progress generally made over time most OTC products do not deliver results implied. Was the reason for this ad funded by OTC industry: http://goo.gl/uRrY78 & the DSHEA "honor system" law of 1994.

No evidence safe or: evidence of any of benefit, only ads for sales. The key role of ubiquinone is within mitochondria. While taking additional can increase concentrations in blood plasma, there is no evidence of this changing concentrations within the mitochondria & clinical trials have not shown benefit. See: https://en.wikipedia.org/wiki/Coenzyme_Q10 & https://en.wikipedia.org/wiki/NADH_dehydrogenase_(ubiquinone).

Very safe: Ubiquinol is found in every cell of our body, in fact life as we know it would not be possible without CoQ10. There are no known interactions with thyroxine and it is safe in pregnancy. It has many proven benefits: https://ubiquinol.org/ubiquinol-coq10-supplement-facts Many people on thyroxine (T4) benefit from the addition of Liothyronine (T3)- see http://tinyurl.com/n4zmkro

Beware: https://ubiquinol.org is a marketing site & it states that the evidence they report: "*These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease." While FDA approval does not mean of value; it does indicate human clinical trial data for evidence of efficacy meeting FDA scrutiny. See my answer.

Caution : A pubmed search indicates several studies that show coenzyme Q10 levels may afffect circulating hormone levels including thyroid hormone. Indeed, hypothyroidism is correlated with high levels of coq10 in many studies so I would avoid this supplement. The FDA does not regulate supplements and its educational to know that doctors do not know of all drug/supplement interactions if not studied.

I appreciate the research you did on this Dr. O'Leary, but while studies do show that those who are hyperthyroid have low CoQ10 levels and those who are hypothyroid have higher levels I know of NO studies showing that taking CoQ10 has an effect on thyroid levels. These studies look at the levels of endogenous CoQ10 levels. See http://www.naturalendocrinesolutions.com/archives/coq10-thyroid-health/
