Oleuropein is a powerful antioxidant substance, which is found in various parts of the olive tree, including roots, bark, fruit, and especially in the leaves. Oleuropein plays a crucial role in the survival of the olive tree. It not only serves as a protective shield against free radicals, but also protects the tree from damage that could be caused by insect infestation, bacteria, viruses, and fungi. Due to the high content of oleuropein, the resilience of the olive tree is increased to such an extent that it has the ability to reach a remarkable age of up to1,000 years.
Oleuropein is particularly interesting in terms of its antioxidant effect. In olive leaves, this super antioxidant is found in approximately3000 times higher concentration than in olive oil.This is because the tree bears its leaves for about five years, and therefore needs to protect them particularly well against pests and fungi during this time. Extracting oleuropein from fresh olive leaves makes it possible to make this powerful yet versatile plant substance available to humans.
The oleuropein content in our olive leaf extracts varies depending on the product. In BIO FORTE 100% olive leaf extract, the oleuropein content is standardized to 10%, which corresponds to a concentration of 12,000 mg per 100 ml. This standardization ensures consistent extract quality and potency. In our other variants (NATURA,PREMIUM, andSTANDARD), where the leaves are wild-harvested, the oleuropein content varies according to the natural conditions of the plants. In the case of wild duck, the leaves are primarily harvested from old trees, as these have a higher oleuropein content. The manual harvesting of olive leaves is not only environmentally friendly but also crucial for product quality.
For our liquid olive leaf extract variants, we do not use a dry extract, but only the 100% pure extract made from fresh leaves.
The various forms and concentrations of our olive leaf extracts offer a wide selection, allowing you to select the olive leaf extract precisely according to your individual preferences and needs. The "PREMIUM" and "STANDARD" versions contain vegetable glycerin (derived from coconuts), which, with its sweet taste, mitigates the bitterness of the extract.
