Olive Leaf Tea has been enjoyed for generations as a naturally caffeine-free herbal infusion made from the leaves of the olive tree (Olea europaea). In recent years, researchers have shown increasing interest in the naturally occurring plant compounds found in olive leaves, particularly polyphenols such as oleuropein and hydroxytyrosol.
These compounds have been studied in laboratory, animal and human research for a variety of biological properties. However, it is important to understand what current research can—and cannot—tell us.
Naturally Occurring Plant Compounds
Olive leaves naturally contain a range of bioactive compounds, including:
- Oleuropein
- Hydroxytyrosol
- Flavonoids
- Polyphenols
These naturally occurring compounds contribute to the unique composition of olive leaves and continue to be the subject of scientific investigation.
What Does Current Research Show?
Researchers have explored olive leaf extracts in relation to several areas of health, including glucose metabolism and insulin function.
Some clinical studies have investigated whether concentrated olive leaf extract may influence insulin sensitivity and blood sugar regulation in certain groups of people. Several studies have reported encouraging findings, including improvements in markers of insulin function. However, the available evidence remains limited, many studies have involved relatively small numbers of participants, and further well-designed, large-scale clinical trials are needed before firm conclusions can be reached.
It is also important to note that the majority of published research has examined standardised olive leaf extracts, which are significantly more concentrated than Olive Leaf Tea prepared as a beverage. Therefore, these findings should not be assumed to apply directly to drinking Olive Leaf Tea.
For these reasons, there is currently no authorised UK health claim stating that Olive Leaf Tea helps regulate blood sugar, improves insulin sensitivity or assists in the management of diabetes.
Why Choose Olive Leaf Tea?
