Does Coenzyme Q10 interact with any drugs?
CoenzymeQ10, also known as ubiquinone or CoQ10, may have serious drug interactions. Use with anticoagulant drugs like warfarin could decrease the blood thinning effects of the anticoagulant and increase the risk for a blood clot, although the available data is conflicting.
If you take a blood thinner, check with your doctor before starting CoQ10. You may need to have your blood clotting tests checked more frequently and may need a change in your anticoagulant dose if your doctor agrees to its use. Do not stop using any medications without first talking to your doctor.
If you are considering the use of any supplement, always check with your doctor first. It is important to tell your doctor about all the medications you use, including prescription, over-the-counter (OTC) medicines, vitamins and herbal supplements.
What is CoenzymeQ10?
CoenzymeQ10 (CoQ10) is an antioxidant found naturally in the heart, kidney, liver and pancreas, but aging and smoking can deplete these natural stores. It is considered a nutraceutical. Cells use it to produce energy and to fight off free-radicals.
CoQ10 is also available as a dietary supplement at the store. This dietary supplement is most likely effective for coenzyme Q-10 deficiency, or reducing the symptoms of mitochondrial disorders, which are conditions that affect energy production in the cells.
CoQ10 is promoted to be effective for migraines, heart conditions like high blood pressure or heart failure, Parkinson's disease or macular degeneration, and to help with muscle problems from statins, but you should only take CoQ10 for these conditions if recommended by your health care provider. These uses are not fully proven in clinical studies.

Does Zinc protect you from Covid-19 or boost your immune system?
Few trials have been conducted that examine the role zinc supplementation or low zinc levels play in Covid-19.

Zinc is an essential mineral that we have to obtain from diet or supplements. It supports normal growth and development during childhood, adolescence, and pregnancy; is responsible for the activity of more than 300 different enzymes in our body; is vital for our immune system functioning; and is important for wound healing.
