KEEP THE BLOOD MOVING - When we think of cardiovascular health we usually think of the heart. But the arteries and veins that circulate your blood are just as important. So we created a formula that combines a special extract of olives with a healthy compound derived from celery to encourage healthy circulation.

HEALTHY BLOOD PRESSURE SUPPLEMENT – The olive tree (Olea europaea) creates a compound called oleuropein in both its fruit and leaves. You might never have heard of it, but you’ve definitely tasted it: oleuropein is the reason high-quality olive oils have a tangy, almost bitter flavor. But taste isn’t oleuropein’s only characteristic—it also helps maintain already healthy blood pressure.

CIRCULATORY HEALTH – If you thought oleuropein was a weird name, check out 3-n-butylphthalide, or 3nB. This healthy celery compound helps relax blood vessels, promote healthy platelet function, and inhibit inflammation to support circulatory health.
