Vital Heart & Vein’s Dr. Patrick Kee was recently featured in Parade alongside three other cardiologists, who agreed that CoQ10, a popular supplement marketed for heart health, is generally not worth the money.
Dr. Kee pointed out that CoQ10 is sold on the promise of boosting the heart’s energy, slowing aging, and protecting the cardiovascular system. In reality, the American Heart Association considers its value in heart failure uncertain. It is not a substitute for standard, guideline-based medical treatment.
The other cardiologists in the article added that CoQ10 can interact with blood thinners such as warfarin and may lower blood sugar, which matters for people on diabetes medications. Supplement quality and dosing can also vary, and time and money spent on a supplement can delay lifestyle changes with stronger evidence behind them.
The cardiologists recommended these steps instead:
- Eat a heart-healthy diet such as the Mediterranean or DASH plan. For a food-first source of CoQ10, oily fish is a good choice.
- Stay active. Aim for at least 150 minutes of moderate aerobic exercise a week, plus some strength training.
- Prioritize sleep. Dr. Kee noted that deep, restorative sleep gives the heart a chance to rest, lowers resting heart rate, and helps regulate stress hormones linked to inflammation and high blood pressure.
If you’re thinking about starting a supplement, talk with your physician first, especially if you take prescription heart medications.
