Where Science Meets Nature: From Leaf to Life
Nestled on 400 pristine acres in South-East Queensland, our olive leaf farm is home to over 550,000 trees, with each one carefully selected for its ability to yield the highest levels of Oleuropein, the powerful polyphenol behind olive leaf’s remarkable benefits.
We grow with intention. Beneficial insects are released among the trees to reduce the need for synthetic chemicals. After extraction, waste leaf is composted and used as mulch around the trees to boost nutrient levels in the soil and to suppress weed growth.
Each morning at sunrise, we begin by assessing the leaves for optimal growth and size, choosing only the freshest leaves at their peak. Within hours, they’re processed at our on-site extraction facility, preserving the natural potency and ensuring guaranteed polyphenolic levels. Each batch is traceable back to the grove, and the exact row it is harvested from.
It’s this care, from grove to bottle, that makes Comvita Olive Leaf Extract truly extraordinary.

Why Fresh-Picked™ Matters
At Comvita, we believe nature knows best. That’s why we only use Fresh-Picked™ olive leaves from our Australian farm in every batch of our extract. Unlike dried leaves or reconstituted powders, fresh leaves preserve the full quality and integrity of their key active: Oleuropein.
Scientific testing shows that liquid extracts made from fresh leaves deliver a broader spectrum of polyphenols and greater potency. By harvesting at sunrise and processing on-site before midday, we lock in the leaf’s natural goodness and avoid the loss that comes from drying, storage, or artificial enhancement.
This also means we keep the natural synergy of the olive leaf intact; a powerful combination of flavonoids, oleuropeosides, and phenols that work together to help fight free radicals more effectively than isolated compounds.
When you choose Fresh-Picked™ Olive Leaf Extract, you’re choosing purity, potency, and the olive leaf as nature intended.
