Side Effects and Counter Indications

Although CoQ10 supplements are generally safe, they may cause some side effects such as nausea, vomiting, loss of appetite, abdominal cramps, and diarrhea.

There are also certain counter-indications for taking CoQ10 supplements such as if you are on warfarin (a blood thinner) or any other anticoagulants; if you have a heart condition; if you have low blood pressure; or if you are pregnant or breastfeeding.

It is important to talk with your doctor before taking any type of supplement - especially one like CoQ10 which has been known to interact with certain medications.

The daily recommended dose for CoQ10 varies depending on the individual but it is generally between 30-200mg per day.

When taking CoQ10 supplements it is important to know that they can interact with other medications and supplements such as Vitamin B12 or calcium channel blockers so it is best to talk with your doctor before taking them.

Additionally, it is important not to exceed the recommended daily dosage as doing so could lead to serious health risks such as liver toxicity or kidney failure in rare cases.


CoQ10 supplements can provide many benefits when taken in the correct dosage and when there are no existing medical conditions or medications that could be negatively affected by their use.

Before deciding whether or not to take a CoQ10 supplement it's important for individuals to understand what the side effects might be, what the daily recommended dose should be for their individual needs, how these supplements might interact with other vitamins and medications, and who should not take them at all due to potential medical issues.

With this information in hand, individuals can make an informed decision about whether they want to include a Coq 10 supplement into their diet regimen - under the guidance of their doctor of course!
