Short answer: CoQ10 supports energy production inside the heart muscle itself, while Hawthorn Berry is a traditional tonic for healthy blood pressure and stress-resistant arteries — two ingredients addressing the heart directly, not just circulation.
CoQ10: cellular energy for the heart muscle
Coenzyme Q10 supports energy production in the heart muscle, contributing to stronger, more efficient pumping function — a mechanism distinct from the circulation-focused ingredients elsewhere in the formula.
Hawthorn Berry: the traditional heart tonic
A traditional heart tonic used to support healthy blood pressure and strong, stress-resistant arteries — a long-standing traditional-use ingredient with a genuine, if more traditional, research base.
Why heart-muscle support matters alongside circulation
Supporting blood flow is only part of the picture — the heart muscle itself needs adequate energy and resilience to pump effectively, which is where CoQ10 and Hawthorn Berry specifically contribute.
