Taking too much CoQ10 can cause several side effects, including nausea, upset stomach, diarrhea, headache, rash, and dizziness. In rare cases, CoQ10 may also cause a decrease in blood pressure, heart palpitations, or an increased risk of bleeding. If you experience any adverse effects from taking CoQ10 supplements, it is important to stop taking them and speak with your doctor.

What is the maximum amount of CoQ10 to take daily?

The recommended daily allowance (RDA) of Coenzyme Q10 (CoQ10) is between 30 and 200 milligrams per day. However, some experts suggest taking up to 400 milligrams per day for therapeutic purposes. It’s important to consult with your doctor before taking any supplement, especially if you are pregnant or nursing, as there are potential side effects associated with taking high doses of CoQ10.

What medications should not be taken with CoQ10?

CoQ10 is a supplement commonly used to support heart health. It is important to note that it may interact with certain medications, including warfarin (Coumadin), blood pressure medications, cholesterol medications, and diabetes medications. If you are taking any of these medications, it is important to speak with your doctor before taking CoQ10 to make sure it is safe for you to do so. Additionally, it is best to avoid taking CoQ10 with any other supplements or herbal remedies, as this could increase the risk of interactions or side effects.
