Widely recorded in traditional medicine for its medicinal properties, hawthorn (Crataegus laevigata) has been extensively studied for its beneficial effects in cardiovascular health. Its unique chemical composition rich in flavonoids and oligomeric proanthocyanidins, especially vitexin have been found to exert antiarrhythmic, hypotensive, and hypolipidemic effects. Some of the postulated mechanisms of action purported to the benefits of hawthorn include inhibition of phosphodiesterase activity, increasing the levels of cAMP in cardiac cells, inhibition of angiotensin converting enzyme which exerts a vasodilating and hypotensive effect, lowering levels of LDL cholesterol by increasing LDL breakdown through hepatic receptors, antioxidant effect by increasing nitric oxide production, and inhibition of the Na+/K+-ATPase pump in cardiac muscles.

Hawthorn SAP provides high quality hawthorn berry extract standardized to vitexin that can help maintain and support cardiovascular health.
