What is CoQ10 plus Selenium Yeast?

Doctor’s Best CoQ10 Plus Selenium Yeast contains the same combination, CoQ10 (200mg) and Selenium (200mcg), as clinically tested with 443 participants in a double-blind placebo controlled Swedish study, KiSel-10. In the KiSel-10 study, participants who took this combination recorded healthier cardiovascular function and higher Health-Related Quality of Life (HRQoL) scores compared to the group who did not.* Our CoQ10 is naturally fermented USP (United States Pharmacopeia) verified and is combined with high quality selenium yeast to create the same synergistic nutrient combination as the KiSel-10 study.

Supports Cardiovascular Health*

A 5-year prospective randomized double-blind placebo-controlled trial among Swedish citizens aged 70 to 88 was performed in 443 participants given combined supplementation of selenium and coenzyme Q10 or a placebo. Clinical examinations, echocardiography and biomarker measurements were performed. Participants were monitored every 6th month throughout the intervention. The cardiac biomarker N-terminal proBNP (NT-proBNP) and echocardiographic changes were monitored and mortalities were registered. This study concluded that long-term supplementation of selenium/coenzyme Q10 reduces cardiovascular mortality by 50%. The positive effects could also be seen in NT-proBNP levels and on echocardiography.1

Supports Thyroid Health*

A randomized controlled prospective study was performed to investigate the effects of selenium (Se) treatment on patients with autoimmune thyroiditis and mild sub-clinical hypothyroidism. A total of 196 patients with autoimmune thyroiditis were recruited in the study. Patients were assigned to receive (case) or not receive (control) an oral selenomethionine treatment. Cases received 83 mcg selenomethionine/day orally for four months. All the patient’s charts were submitted to thyroid hormonal profile (TSH, fT4) and TPOAb evaluation upon enrollment and at end of study. The study concluded that selenium supplementation could restore normal levels of thyroid hormone levels (euthyroidism) in one third of subclinical hypothyroidism patients with autoimmune thyroiditis.17
