Why is olive leaf extract necessary for your body?
Olive leaf extract appears to exert various benefits associated with its purported antioxidant activity. Most notably, oleuropein seems to directly attack most types of viruses, which could make this substance even more effective than antiviral treatments that bolster your immune system’s innate defences. Furthermore, oleuropein also appears to bolster your cardiovascular system, prevent neurological damage, and improve metabolism in both healthy individuals and people who suffer from diabetes or obesity.
Functions of olive leaf extract
- Potential immune benefits: Research indicates that oleuropein may fight a variety of different types of viruses. Studies have mainly focused on olive leaf extract’s potential to fight herpes, but it appears that this substance may also be useful for many other viral infections.
- Potential cardiovascular benefits: Olive leaf extract may lower blood pressure and reduce levels of harmful cholesterol in your blood.
- Potential neuroprotective benefits: Research indicates that oleuropein may prevent nervous system tissue damage that often results in common neurodegenerative diseases like Alzheimer’s disease and Parkinson’s disease.
- Potential metabolic benefits: Scientific evidence shows that olive leaf extract may increase insulin secretion, which reduces blood glucose levels and prevents the symptoms of diabetes. Olive leaf extract may also prevent hyperinsulinemia, which occurs when there is too much insulin in your blood.
- Potential weight loss benefits: Studies show that olive leaf extract may help with obesity. It appears that olive leaf extract exerts these potential benefits by modulating the expression of obesity-related genes.
