Experts warn on CoQ10 supplements: Know the benefits and risks before buying

Waking up early in the morning, going for a jog, eating a healthy breakfast and avoiding snacking on junk. There's a whole lot of tasks added to your to-do list when you are trying to live life the right way.Then, as is the case with everything, people created a swifter and smarter way of doing it all- taking supplements. Now every home drawer is filled with at least 5 bottles of different supplements that focus on body health and save you from the time and energy of cooking health-conscious meals and walking every day.From magnesium to iron, supplements take care of ensuring the body gets all the vital nutrients, which is why they have everyone running to the doctor to prescribe them the right one.The recent debutant in the viral market is 'energy boosting' Coenzyme Q10 or CoQ10 supplements which are also known to improve heart health. But should you really be adding them to the cart? Here's what experts say:

Why CoQ10?

CoQ10 is a natural compound present in every cell. It helps turn food into usable energy and also protects the cell from everyday wear and tear.However, with age, the levels of the compounds and the amount of the compound in the body are lowered in production and may drop even more with the use of certain medications.

In this case, most end up reaching for supplements marketed to improve heart health, energy, muscle recovery and brain protection.

Should you add CoQ10 to the cart?

A 2025 study published in the International Journal of Cardiology Cardiovascular Risk and Prevention, analysed the effects of CoQ10 supplements on blood pressure and heart rate to find them effective in reducing systolic blood pressure at doses below 200mg/day with longer treatment durations. However, it found the supplement's effect on diastolic blood pressure and heart rate to be minimal.Experts suggest it is safe for most people but there can be side effects such as upset stomach or insomnia. However, the NCCIH cautions that it can interfere with certain medications such as blood thinners, insulin and some types of cancer treatment.In terms of heart health, cardiologists are intrigued but cautious. A 2022 American College of Cardiology (ACC) press release noted that CoQ10 was among the few micronutrients that were linked to reduced cardiovascular risk and potentially a decrease in all-cause mortality.However, the same release added that more high-quality studies are required before doctors can recommend it across the board.

What's the future of CoQ10 supplements?

Supplements are not tightly regulated by the FDA, meaning that each capsule of the supplement could contain a different amount across brands.Experts recommend looking for products that are third-party tested, such as those with USP (U.S. Pharmacopeia) seals to ensure quality and purity.Since the supplement is fat-soluble, the National Institute of Health advises taking it with a meal that is packed with some healthy fat for better absorption.While 100mg and 200mg of CoQ10 can be tolerated by people every day without issue, it is better to ask your doctor about the right dose for you.While CoQ10 might be generally safe and can offer some benefits for blood pressure and hypertension, it's not the 'magic' pill everyone thinks it is and should be taken after consultation with your doctor.
