Cardiovascular Health Supplements: Reviews by Dr. Bell

Cardiovascular health is the long game. Most of what shows up as a heart event in your fifties or sixties was set in motion decades earlier — in blood vessels, blood lipids, blood pressure, and the slow accumulation of inflammation. The good news is that the same factors that build cardiovascular risk are the ones that respond to lifestyle and nutrition support.

Most cardiovascular supplement work falls into a few categories: omega-3 fatty acids for membrane health and inflammation, CoQ10 for mitochondrial energy in the heart muscle (especially important if you take a statin), magnesium for blood pressure and heart rhythm, and targeted botanicals or amino acids for circulation, cholesterol, and arterial flexibility.

This page collects every Designs for Health cardiovascular supplement I have reviewed — what it is for, who tends to do well on it, who should be careful, and how to dose it. The reviews lean toward what I see in practice rather than what is on a label. If you are on prescription cardiovascular medication, always run new supplements past your prescribing doctor before starting them.
