Coenzyme Q10, better known as CoQ10, is a trendy supplement touted for boosting energy and heart health, but how do the benefits stack up against the risks?
CoQ10 is a natural compound found inside every cell, where it helps convert food into usable energy. It also acts as an antioxidant, helping to protect cells from daily wear and tear, according to multiple health sources.
Because CoQ10 levels naturally decline with age and can decline further with certain medications, many people turn to supplements, which are often marketed for heart health, energy, muscle recovery, and even brain protection.

But before you throw a bottle in the cart, here’s what cardiologists and health experts have to say about it.
According to the National Center for Complementary and Integrative Health (NCCIH), CoQ10 plays an important role within the body, but there is no conclusive clinical evidence that it can prevent or treat disease generally.

Some studies suggest that CoQ10 may slightly lower blood pressure or relieve fatigue caused by prescription drugs that lower cholesterol, but large, well-designed trials have not confirmed significant benefits for Parkinson’s, heart disease, or other conditions.

Still, experts say CoQ10 is considered safe for most people. The main side effects are mild, such as upset stomach or insomnia, but the NCCIH warns that the supplement may interfere with certain medications, including blood thinners and insulin.

Cardiologists are intrigued, but cautious. A 2022 American College of Cardiology (ACC) news release noted that CoQ10 was among a handful of micronutrients linked to a reduction in cardiovascular risk and potentially a decrease in all-cause mortality.
However, the same statement emphasized that more high-quality studies are needed before doctors can recommend it across the board.

Because CoQ10 can help relax blood vessels, it can sometimes cause blood pressure to be lower than expected, experts warn.

Unlike prescription drugs, supplements are not strictly regulated by the FDA. That means the amount of CoQ10 in each capsule can vary greatly between brands.
It is recommended to look for products that have been third-party tested, such as those with USP (U.S. Pharmacopeia) seals, to ensure quality and purity.

CoQ10 is fat-soluble, so it should be taken with a meal that contains some healthy fat for best absorption, according to the National Institutes of Health.
Most people tolerate between 100 mg and 200 mg of CoQ10 per day without problems. However, experts recommend talking to your doctor to determine the right dosage for you.

Experts agree that while CoQ10 is generally safe and may offer some benefits, it is not a miracle pill.
People with heart failure or frequent migraines may benefit from the supplement, but should consult with a doctor first, according to the Mayo Clinic.
