Why NZ Olive Leaf Is a Heart Health Powerhouse
That’s right. Everee #5, your go-to collagen source for healthy ageing, not only comes packed with more muscle-, joint- and brain-supporting amino acids than conventional collagens, it also contains oleuropein — a powerful polyphenol derived from New Zealand olive tree leaves.
What is oleuropein and how does it support heart health?
Most people are familiar with the heart-health benefits of olive oil as part of the Mediterranean diet. What’s less well known is that New Zealand olive tree leaves contain the same polyphenolic compounds as extra virgin olive oil — in even higher concentrations (1), (2).
One of these compounds, oleuropein, is particularly effective at supporting cardiovascular health.
How does oleuropein help the heart?
Oleuropein is a potent antioxidant and anti-inflammatory compound (3), (4). It helps reduce oxidative stress by protecting low-density lipoproteins (LDL) from oxidative damage (2), (5).
This is critical, as oxidative modification of LDL plays a central role in arterial hardening and the development of cardiovascular disease.
Clinical studies have also shown that oleuropein helps prevent myocardial injury (6) by increasing nitric oxide production. Nitric oxide widens blood vessels, improves blood flow and reduces tissue damage caused by low oxygen levels (2).
A 2022 animal study (7) further found that oleuropein not only improves inflammatory and oxidative markers, but may also help prevent postmenopausal osteoporosis by regulating key bone-remodelling proteins (OPG/RANKL).
What’s the take-home message?
There is strong and growing scientific evidence supporting the role of olive leaf polyphenols in heart health. That’s why we chose to include a potent olive leaf powder sourced and made in New Zealand alongside Ovitage® — the world’s most complete collagen — in Everee #5.
Together, they work to support cardiovascular health, help reduce the impact of cholesterol and provide meaningful cardioprotection.
How good does that sound?
