Olive leaf extract has had a long history in traditional medicine, being used to prevent, treat or manage inflammation and infections (such as the common cold or influenza), diarrhoea, cardiovascular system function and osteoarthritis.
Produced from the leaves of the olive plant, research shows that the major active ingredient Oleuropein, has antibacterial, anti-inflammatory and immune-stimulating properties.
The benefits
Olive leaf extract has been used traditionally in western herbal medicine for:
- Coughs, colds and influenza. Relieves symptoms of coughs, colds and influenza, sore throats and upper respiratory tract infections;
- Immune support and general wellbeing. Supports the immune system and when taken daily, it also helps maintain general wellbeing;
- Natural antioxidants. Olive leaf extract has powerful antioxidant properties to fight free radical damage;
- Insulin sensitivity. Olive leaf extract may improve insulin sensitivity and overall blood glucose response, reducing the risk of developing diabetes and improving overall weight management;
- Cardiovascular system function. Olive leaf extract can also be used to help regulate blood pressure, maintain normal heart and overall cardiovascular system function.
How to supplement with olive leaf extract
You can purchase olive leaf extract in capsule and liquid form. There is no actual recommended dosage, however the standard dose ranges from 500mg to 1500mg daily.
Doses can be divided into several smaller doses if required.
Are there risks or side effects
If you are currently taking blood pressure or blood thinning medication, or have diabetes it is recommended that you consult with a medical professional prior to trying olive leaf extract.
In extreme cases, it is possible to develop a respiratory allergic response.
My two cents
Olive leaf extract is just about the only supplement that I have personally found to noticeably reduce the severity and duration of colds and flu-like illnesses. On occasion, I’ve noticed a difference within 24 hours of supplementation. As a result, I’ll keep a bottle in the fridge and supplement daily throughout the cold and flu season.
Anecdotal and n=1 yes, but this stuff works for me.
Finally, this isn’t a cure-all supplement, but it may help with the reduction of the severity of colds, improved blood glucose response, leading to improved weight management, overall health and performance, along with some boosted immunity.
