Short answer: Hawthorn Berry is packed with bioflavonoids that help dilate peripheral blood vessels, improving blood flow to the extremities.
Why "peripheral" and "extremities" are specific, meaningful terms
This distinguishes Hawthorn Berry's specific contribution — blood flow to hands, feet and legs — from a more general, whole-body circulation claim.
Why bioflavonoids specifically matter for vessel dilation
Naming this specific compound class gives you something concrete and checkable to research independently, rather than a vague "supports blood flow" claim.
💡 Worth knowing: this ingredient rounds out the formula's circulatory-strength category alongside Grape Seed Extract.
