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

Learn more about the connection between hydroxytyrosol and olive leaves

For over five decades, Comvita has drawn on nature to support everyday wellness.

Our Olive Leaf Extract is made from fresh-picked leaves grown on our own groves in Queensland, carefully extracted to preserve their natural concentration of beneficial compounds.

One of the most valuable of these is hydroxytyrosol — a well-recognised antioxidant polyphenol found in olives and olive leaves. Discover how hydroxytyrosol supports your health and well-being, and how Comvita’s Olive Leaf Extract offers a concentrated source of the compound for daily antioxidant support.

What are hydroxytyrosol polyphenols?

Hydroxytyrosol is a naturally occurring, beneficial compound found in olives and olive leaves. As a type of phenolic compound, hydroxytyrosol belongs to a family of plant-based antioxidants known for their role in helping protect against free radical damage in the body. These bioactive compounds help neutralise free radicals and reduce oxidative stress, supporting overall well-being.

Due to its small molecular weight, hydroxytyrosol is easily absorbed by the body, making it a highly bioavailable antioxidant. While present in olive oil, it’s far more concentrated in Olive Leaf Extract — a preferred choice for those seeking a bioavailable source of polyphenols.

Hydroxytyrosol does not appear in olive leaves in isolation. It is formed in the body from a parent compound called oleuropein. To understand why Comvita’s Olive Leaf Extract is such a rich source of hydroxytyrosol, it helps first to understand oleuropein and how it functions.

Oleuropein: A precursor to hydroxytyrosol

Oleuropein is a phenolic compound with strong antioxidant activity, also studied for its broader wellness applications. Inside the body, it’s converted into hydroxytyrosol by enzymes and gut microbiota, making oleuropein-rich supplements like Comvita’s Olive Leaf Extract a smart way to support everyday health and well-being.

Why Comvita prioritises oleuropein:

  • It is a key marker of freshness and potency in our fresh-picked olive leaves
  • It contributes to the antioxidant capacity of our extract
  • It is carefully measured and tested in every batch

By extracting fresh leaves daily from our Queensland grove, we’re able to maintain high levels of oleuropein and its downstream compounds, including hydroxytyrosol, for consistent quality.

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

Phenolic compounds like oleuropein and hydroxytyrosol are valued for their antioxidant activity. These natural compounds may help protect against free radical damage, and support overall wellness. In Western herbal medicine, olive leaf has traditionally been used to support immune system health and cardiovascular function.
