Hydroxytyrosol and Olive Leaf Extract: Natural Support for Your Health and Wellness

Learn more about the connection between hydroxytyrosol and olive leaves

For over 50 years, Comvita has worked with nature to support everyday wellness.

While Mānuka Honey is well known in New Zealand, Olive Leaf Extract may be less familiar, yet it’s long been valued for its natural compounds. At Comvita, we craft our Olive Leaf Extract from fresh-picked leaves grown on our own groves in Queensland in Australia, carefully processed to retain their natural phenolic compounds. 

Among these are oleuropein and hydroxytyrosol, two bioactive compounds that continue to spark growing scientific interest for their natural, beneficial properties.

This guide discusses what hydroxytyrosol is, why it's being studied,, and how Comvita’s Olive Leaf Extract makes it simple to explore the natural benefits of the olive leaf.

What are hydroxytyrosol polyphenols?

Hydroxytyrosol is a naturally occurring compound found in olives and olive leaves.

As part of the polyphenol family, it belongs to a group of plant-based antioxidants studied for their role as plant-based antioxidants. Because of its small molecular weight, hydroxytyrosol is easily absorbed by the body, which is why it continues to attract scientific attention as one of the most bioavailable olive compounds.

If you’re looking for a hydroxytyrosol supplement, Olive Leaf Extract is considered one of the best sources of hydroxytyrosol, offering a much higher level of concentration compared to olive oil.

Oleuropein: A precursor to hydroxytyrosol

Oleuropein is the dominant phenolic compound in olive leaves. It’s a natural indicator of freshness, and when broken down in the body, it converts into hydroxytyrosol, amplifying the extract’s antioxidant profile. 

Why Comvita prioritises oleuropein:

• Acts as a benchmark for the strength and integrity of every batch
• Supports the extract’s overall antioxidant activity
• Verified through transparent lab testing to ensure reliable levels

This combination of oleuropein and hydroxytyrosol explains the extract’s recognised antioxidant capacity and the interest in its potential benefits for everyday wellness.

How do the phenolic compounds in Olive Leaf Extract support wellness?

Comvita Olive Leaf Extract is naturally rich in hydroxytyrosol and oleuropein. Together, these beneficial compounds act as antioxidants, which are known to help neutralise free radicals.

Researchers are also investigating Olive Leaf Extract in areas such as cardioascular health and blood sugar balance. While findings remain preliminary, this growing interest reinforces why olive leaves have been valued for centuries in Mediterranean traditions.

Each bottle of Comvita Olive Leaf Extract is crafted from fresh-picked leaves to retain these beneficial compounds, offering a simple way to add olive goodness to your diet.
