Olive Leaf And Circulation: An Often-Overlooked Ingredient
Olive leaf contains polyphenols, including oleuropein, studied within the broader body of Mediterranean-diet cardiovascular research.
It tends to sit in Hawthorn's shadow in most formulas, but the underlying research context is genuinely substantial.
Part of a larger dietary pattern
Much of the strongest research context for olive-derived compounds comes from studies on the Mediterranean diet as a whole, not olive leaf extract in isolation. A landmark trial published in the New England Journal of Medicine (PMID 23432189, 2013) examined Mediterranean diet patterns, which prominently feature olive oil and olive-derived compounds, and cardiovascular outcomes.
More recent, more specific research
A 2024 systematic review in Current Hypertension Reviews (PMID 39558500) looked specifically at olive oil supplementation and blood pressure, narrowing the focus closer to the kind of extract-based supplementation used in a product like PressureCalmX.
Being honest about the gap
Applying this to PressureCalmX
Olive Leaf is one of eight botanicals in PressureCalmX's formula, included for its oleuropein content and antioxidant association. As with the other botanicals in the blend, its individual dose is not broken out on the label.
