If you have already purchased a product, this page will help you decide what olive leaf extract dosage to take within the manufacturer's recommended range.
If you are wondering what to purchase, it will show you what strength you need to look for in a product for your particular purposes.
Then go to olive leaves to help you choose the best dosage form of olive leaf to take.
Having said that, correct olive leaf extract dosage is very important if success is to be had, and certain things need to be understood, especially where disease conditions are present.
These are highlighted in 8 points further down this page.
If a product has "extra strength" or "super potency" splashed all over the label without quoting actual oleuropein concentration or tincture strength, be suspicious.
If you want to take it to alleviate a real problem it may produce disappointing or no results.
Step 1:From the list below, decide how many mg. of oleuropein is required per day for your purpose. These values I have found empirically (by trial and error).
Health Maintenance: 25mg per day divided into 1-2 doses
Disease Prevention: 75mg per day divided into 3 doses
Acute Illness: 180mg per day divided into 3-5 doses
Health Maintenance: 12.5mg per day divided into 1-2 doses
Disease Prevention: 38mg per day divided into 3 doses
Acute Illness: 90mg per day divided into 3-5 doses
Health Maintenance: 7mg per day divided into 1-2 doses
Disease Prevention: 18mg per day divided into 3 doses
Acute Illness: 40mg per day divided into 3-5 doses
Health Maintenance: 5mg per day divided into 1-2 doses
Prevention: 12mg per day divided into 3 doses
Acute: 25mg per day divided into 5 doses

Consult your health care professional.
Step 2.Tinctures only.
Capsules and powder - For adults, add 20% to 30% to the oleuropein requirement due to reduced absorption.
For children, do not add the extra.
Calculate how many capsules are required to supply this amount of oleuropein.
Proceed to step 3.
Step 3.Divide this total dose up into 1 to 5 doses per day according to the list.
Check that this falls within the manufacturer's recommended range.
Step 1.You need 75mg oleuropein per day according to the list.
Capsules, add 25% to the required dose (due to lower capsule absorption).
This gives you 75mg+18.75mg = 93.75mg approx. needed per day.
Your capsules contain 35mg oleuropein each, so you need 93.75mg divided by 35mg = 2.68 capsules per day.Round this up to 3 capsules per day.
Go go to step 3
Step 3.From the list, ideally you need 3 doses per day so take 1 capsule 3 times a day.
Step 4.Finally, double check that this is within the dosage given on the container.
These basic olive leaf extract dosages may be adjusted if necessary taking into account the eight factors below.
Olive leaf extract has been shown to lower high blood pressure, regulate blood sugar levels and prevent blood platelets from sticking together. While this is good news for the average person, it may add to the effect of high blood pressure medication (bringing it too low), alter required insulin dosage in diabetics and increase the effect of blood thinners such as Warfarin.
Anyone using medication for any of these conditions should consult their doctor before dosing with olive leaf extract.
People who typically have low blood pressure should first try small doses (about half a maintenance dosage for your age) to check if it has any lowering effect on their blood pressure causing for example a feeling of dizziness when standing up suddenly.
If no effect is noticed, build up to the recommended dosage over a few days.
Pregnant or breast-feeding?It is not advisable to take olive leaf extract when pregnant or breast-feeding. It may cause you to detox heavily, lower blood pressure etc. and this is definitely an issue to be discussed with your qualified health care professional.
Some disease-causing microbes (pathogens), particularly in areas such as the digestive tract, sexual and urinary organs,
sinuses and ear, nose, throat, lungs, lymph glands, joints, and meninges (protective membranes around the brain) are able to
evade your body's immune cells.
When the pathogens' cell walls are damaged by olive leaf constituents, their "remains" are then absorbed by the sensitive surrounding tissue, triggering an immune response and causing inflammation, pain and a temporary worsening of original disease symptoms.
They may also appear as mild 'flu-like symptoms. This lasts until the body has processed these destroyed microbes and is usually followed by a surge of energy and a feeling of well-being.
Herxheimers reaction is experienced in a small minority of people and usually lasts about 4-7 days.
It is a good indication that the olive leaf extract dosage is working.
It stands to reason that someone carrying a heavy load of pathogens should kill them off slowly in order to avoid unnecessary discomfort or overload.
This is particularly the case in the old, frail and chronically ill.
Start with the minimum age-related olive leaf extract dosage on the container and increase day by day until die-off symptoms are experienced.
Maintain that dose or increase as comfortable until the maximum dosage is reached. If uncomfortable, reduce dosage of olive leaf extract for a few days or stop taking it and start again in a few days.
It is better not to stop if possible.
A useful hint when overcoming the early stages of an infection is to take half the recommended dosage of a tincture and half
the recommended dosage of a capsule product together.
While this means buying two products it gives both a quick-acting and a sustained effect.
Because not all olive leaf extracts are the same, different cultivars having different constituents and amounts of constituents during different seasons, and because like any other herb these components interact with our bodies in a complex and individual way, different products may not have the same effect on everyone.
Some benefits will only be experienced by using a sufficiently strong dosage of an olive leaf extract product which has all the constituents necessary for the desired effect.
For this reason, the benefits of a particular brand depend on the quality of the product itself.
The benefits of a highly concentrated, good quality product will differ widely from those of a weak product
made from the cheapest leaves available.
A product standardised in terms of one particular ingredient may be deficient in other ingredients which are collectively responsible for some of the properties of olive leaf extract.
If you are accustomed to it, you can immediately go to the maximum dose of olive leaf extract when you feel you are coming down with a viral or other infection.
If you have a chronic or long-term illness, or have never taken olive leaf extract before, it is best to start on a low dosage and build up to the recommended dose over a few days or weeks as you feel comfortable.
The same dosage can be used for all kinds of infections, up to the maximum recommended dose. In some cases, Herxheimers reaction may determine the rate you increase olive leaf extract dosage.
Most manufacturers show olive leaf extract dosages for children from 2 years of age upwards.
Tinctures are sometimes administered from age 1 year up.
The manufacturer's stated 1-year-old dosage should be about the 2-year-old dose in the guidelines above reduced by 30%.
The tendency is to give very young children too much because it "looks so little".
Rather go by the manufacturer's recommendations, not the looks.
For adults, the older you are the higher the olive leaf extract dosage generally needed to have the same effect as on a younger person with a healthy immune system.
In general, a large-framed person will need more than a smaller-framed person. If you are substantially above average weight and size build up to a higher olive leaf extract dosage.
An elderly person who is very small should start on a small adult dose and slowly increase until the desired effect is achieved.
The same applies to children.
If dosages are given in a range, for example 5-10 drops for children aged 6-10, give a 6-year old 5 drops, or a 10-year old 10 drops.
Don't start the 6-year-old on 10 drops.
Likewise don't give your 13-year old son the maximum adult dose because he is over 12. Roughly gauge where your child should be in the age range according to age and weight.
As already mentioned, olive leaf extract is a forgiving herb and too much will not likely cause any harm but use common sense to avoid wastage and also ensure a big enough dose to make a difference. Too much too soon can cause too much stress on the system.
As already mentioned, a sickly person or one with chronic illnesses should start off on a low dosage.
You may end up taking a relatively large olive leaf extract dosage to finally eradicate the illness but start slowly and give your body time to recover.
For how long should I take olive leaf extract?
This depends firstly on why you are taking it. These are my personal views based upon my own understanding of health. Others may differ.
a.) Children should not be given olive leaf extract permanently like a vitamin tonic as they need to build up their own immune systems.
They should be given it when they are sick (if olive leaf extract is appropriate), when sickness is doing the rounds at school,
for a few days in preparation for exams when under stress and perhaps before and during winter when colds and flu are about.
It is also a good idea to dose children before a school outing to museums and when using public transport if they are not used to it.
Other than that, a healthy diet and exercise should keep them in good shape.
After a winter season of taking olive leaf extract, it is a good idea to give the family a course of good probiotics to ensure a healthy, balanced digestive system.
b.) Adults with chronic conditions can take olive leaf extract indefinitely if appropriate to the ailment or if a long term treatment
For example, some people take olive leaf extract every day to keep sinus infections under control.
I have spoken to an elderly lady who had almost no immune system after a career as a radiologist in the early days when safety was not up to scratch. She was adamant that her daily dose of olive leaf extract was her immune system.
It would be well for such people to eat fermented foods or take probiotics regularly to ensure a healthy digestive tract. (Yoghurt is not sufficient).
For a bad dose of candida albicans or thrush, olive leaf extract dosage should be part of a planned treatment which tapers off as the correct flora are rebuilt in the gut and vaginal tract and healthy foods and habits take over from damaging ones.
c.) For acute illnesses in adults or children, continue with a lower olive leaf extract dosage for at least a week
after you are feeling better.
The tendency is to forget to take it when you feel better because you don't realise that it is still destroying pathogens. You will soon find out what it was doing if you stop too soon, and the second time it often takes longer to subdue the illness.
Now you are armed with the dosage you need to build up to as well as what to start on, go to olive leaves to help you choose a dosage form to take.
