Olive Leaf capsules contain dried olive leaves, concentrated powdered extracts of olive leaves or a combination of both with or without excipients.
Effective for most uses they do not work quite as quickly as the tinctures nor are they as effective for mouth and throat infections.
For longer term systemic use and intestinal cleansing however, they are ideal.
Have a look at the benefits and drawbacks below, then follow the links to tinctures, powders and teas to see which will work best for you.

Olive leaf capsules can contain more active ingredient per dose than tinctures or teas. This can be an advantage for tackling some infections.
A 500mg capsule containing pure olive leaf extract standardised to 20% oleuropein will contain more oleuropein than a dose of tincture or tonic, even if highly concentrated.
Olive leaf capsules work well for infections susceptible to oleuropein and its metabolite hydroxytyrosol.
They can be conveniently carried and easily taken with a little water. Children's doses can be obtained by opening the weaker strength capsules and dividing the contents in half for example. (The powder is more palatable for children when mixed into a little honey.)
Capsule ingredients are not absorbed into the system as well or quickly as other forms (tinctures, teas).
Volatile constituents will have been lost during processing and they will not be absorbed as completely into the body as a tincture for example which is transported into the blood stream through the mouth, stomach and small intestine lining by the alcohol in which it is dissolved.
Pure powdered extracts (see Best Olive Leaf Capsule for You below) can cause stomach irritation if they are too concentrated.
This can be resolved by taking them with meals, however the amino acids glycine, lysine, cysteine and histidine may reduce the virucidal activity.*
The capsules containing dried olive leaves combined with concentrated olive leaf extract are gentler and provide a better balance of active ingredients. These types should not cause stomach irritation.
Strong capsules are not as easily divided up into children's doses as the tinctures are.
Excipients (non-active ingredients) are usually added to the capsule contents to prevent clogging of
the filling machinery and to add bulk.
While many of these are safe, recent research indicates that some such as magnesium stearate and titanium dioxide should be avoided.
I would personally avoid talc-containing capsules/pills which may act as an irritant to damaged intestinal lining, especially if they are taken long term as in vitamin supplements.
Legally, excipients need not be shown on labels if only added to assist manufacture so you may not know they are there.
Some capsules do not use excipients or fillers and this would be indicated on the label.
1. An accurate description of strength in mg of dry leaf per capsule.
2. The quantity of powdered extract in mg per capsule and at what % of oleuropein (indicative of potency).
3. Does the manufacturer grow their own leaves or have control over the cultivation of the plants?
4. Are the leaves organically grown? This is usually a good sign.
5. Are they a mixture of dried leaves and powdered extract? This gives a better spread of active ingredients.
6. Are fillers and excipients absent? Some companies use other dry herbs as fillers which is preferable to inert fillers.
