    Hello.

    I recently read that olive leaf extract is great for thyroid boosting. Also it is marketed for a fat loss supplement.

    Anyone tried it? What were your results?

    @Daniel11 tried it and spoke well about it....
    I have been advised to take it too after some labs....
    I do not order, ....I munch direct on the trees! Maybe 1 leaf a day keeps the doctor away!

    I bought dried olive leafs once and used it instead of tea. But didn't notice any effect. Maybe it was not strong enough made with boiled water .

    Thank you , @Daniel11 ! I wonder if an olive leaf tisane is a part of benefits of Mediterranean diet . Do people in olive trees countries consume not only olive oil and olives, but also the leaves of the tree...

    Thats a good question, research is suggesting that the polyphenols in olive oil and olive leaf are what is greatly contributing to the health benefits, olive leaf has a greater amount and variety of polyphenols then olive oil. From my own experience olive leaf has some unique nutritional qualities and effects that i don't notice with olive oil.

    This article has a lot of interesting research.

    "Olive oil has gained support as a key effector of health benefits and there is evidence that this relates to the polyphenol content. Olive leaf extract (OLE) contains a higher quantity and variety of polyphenols than those found in EVOO."

    "Phenolics are one group for which there is robust evidence supporting the health promoting effects of antioxidants. There is a general consensus that olive leaf phenolics have a strong ability to scavenge nitric oxide (NO) and quench Reactive Oxygen Species"

    Hi Xisca!

    Thats great your eating the leaves i would do same if i had them growing in my yard. The whole leaf is utilized well by the body, but making tea from the leaves is not an efficient way to consume, hot water does not extract the full range of the constituents. Eating the whole leaf or capsules with fresh dried powdered leaves works well, ethanol extractions are quite potent also.

    For sure I want to use more olive oil, to taste as usual, and will use the STRONGest taste I can find instead of the mildest!!!
    -> more polyphenols

    Well, what's about boosting thyroid with this?

    In this article the authors found that water extraction is actually good!

    Optimization of the Aqueous Extraction of Phenolic Compounds from Olive Leaves

    Abstract: Olive leaves are an agricultural waste of the olive-oil industry representing up to 10% of the dry weight arriving at olive mills. Disposal of this waste adds additional expense to farmers. Olive leaves have been shown to have a high concentration of phenolic compounds. In an attempt to utilize this waste product for phenolic compounds, we optimized their extraction using water—a “green” extraction solvent that has not yet been investigated for this purpose. Experiments were carried out according to a Box Behnken design, and the best possible combination of temperature, extraction time and sample-to-solvent ratio for the extraction of phenolic compounds with a high antioxidant activity was obtained using RSM; the optimal conditions for the highest yield of phenolic compounds was 90 °C for 70 min at a sample-to-solvent ratio of 1:100 g/mL; however, at 1:60 g/mL, we retained 80% of the total phenolic compounds and maximized antioxidant capacity. Therefore the sample-to-solvent ratio of 1:60 was chosen as optimal and used for further validation. The validation test fell inside the confidence range indicated by the RSM output; hence, the statistical model was trusted. The proposed method is inexpensive, easily up-scaled to industry and shows potential as an additional source of income for olive growers.

    And this method of extraction was used for example in this study :
    Phytochemical Properties and Anti-Proliferative Activity of Olea europaea L. Leaf Extracts against Pancreatic Cancer Cells


    So it seams that when someone has good source of olive leaves - it is actually possible to make an extractions.

    Yes but its still not the most efficient way to extract and consume the olive leaf, this study is extracting the olive leafs in a very controlled setting at a exact temperature of 90 C (194 F) for 70 min, and even at that the water still did not extract near as much of the beneficial constituents as the ethanol (alcohol) extract.

    "The water extract had a lower level of total flavonoids and oleuropein while the methanol extract had a lower level of total flavonoids, when compared to the ethanol extract. Flavonoids are the largest group of phenolic compounds and include both polar and non-polar moieties. The 50% ethanol extract contained more than double the total flavonoids compared to the water extract"

    I'm sure just making tea with hot water would be good for you, but a alcohol and water (ethanol) extract will yield more of the phenolic compounds and most important have a higher oleuropein content. This is standard botanical knowledge that alcohol and water together make the best solvents, its easy to make your own tinctures (ethanol extract) at home from Vodka, i have done this many times, vodka is a good balance ration of water and alcohol, just fill up glass jar with the olive leafs add the vodka until it covers all the leafs, shake every day after 6-8 weeks, filter the liquid and thats it. You can do the same with many herbs and save a lot of money and its fun, is especially wonderful to do if you have the botanicals growing near you.

    Here is great article on how to make tinctures

    Its interesting research you brought up, i always thought of and used olive leaves as a antimicrobial, i had not taken any for a while so decided to give it a try again focusing on its other actions, i would say it definitely does have a metabolism boosting effect, along with its other qualities this makes olive leaf quite useful for ones health.

    Great discovery thank you!

    I also noticed some research on its antidiabetic effects

    Thank you for information about alcohol tincture.

    Your welcome, and i still think olive leaf is one of the herbs that works well just ground up and put in capsules, as long as fresh.
