Most people with type 2 diabetes know they need to manage their blood glucose levels, but many may not realize they are at higher risk for heart disease. One potential option for reducing that risk is coenzyme Q10, a naturally occurring antioxidant. A recent study found that supplementing with coenzyme Q10 (CoQ10) helps lower blood pressure in people with type 2 diabetes.

Researchers reviewed data from 16 clinical trials that measured CoQ10 levels in people with type 2 diabetes. They focused on changes in blood pressure and cholesterol levels, comparing those who took the supplement to those who did not.

Their analysis revealed that CoQ10 lowered systolic blood pressure by about 4 mmHg and diastolic blood pressure by about 3 mmHg. While it didn’t improve cholesterol levels overall, some subgroup analyses showed better results with lower doses (100 milligrams daily or less) and shorter study durations (less than 12 weeks). Notably, these findings were more pronounced in studies with larger participant groups (more than 50 people) and participants aged 55 or younger.

A reduction of 4 mmHg in systolic blood pressure may seem modest, but even small reductions can lower the risk of heart disease and stroke. For example, a comprehensive analysis found that a 5-mmHg decrease in systolic blood pressure reduced the risk of major cardiovascular events by approximately 10%00590-0/fulltext).

These findings suggest that CoQ10 could be a useful addition to diabetes treatment for managing blood pressure and reducing cardiovascular risk.
