Viridian Olive Leaf Extract
Olive leaf extract helps protect your cells with the same family of polyphenols that makes the Mediterranean diet worth talking about, and Viridian gives you the leaf two ways in a single daily capsule.
It suits adults who want a simple, plant-based antioxidant habit, people looking after their heart and circulation as a matter of routine, and anyone who reaches for something herbal when the season turns. The olive tree has been used as medicine around the Mediterranean for thousands of years, and the leaf, rather than the fruit, is where the strongest concentration of its signature compound sits.
The Leaf Behind the Mediterranean Diet
Everyone knows about olive oil. Far fewer people know that the leaf is richer in polyphenols than the oil is. Oleuropein, the compound that gives a green olive its bitterness, is present in the leaf at concentrations the fruit never reaches.
That is why olive leaf has its own long tradition, separate from the kitchen. Around the Mediterranean it was made into teas and tinctures for centuries, and modern manufacturers concentrate it so you get a measured amount rather than whatever a handful of leaves happens to hold.
What Oleuropein Is, and Why Standardising It Matters
Oleuropein is a polyphenol, one of the plant compounds that behaves as an antioxidant in the body. It is what researchers measure when they study olive leaf, and it is what a good manufacturer guarantees.
This extract is standardised to 18% oleuropein. Standardisation means every capsule is tested to hold the same amount, rather than varying with the harvest, the weather and the age of the leaf. It is the difference between a herbal supplement you can rely on and one you are simply hoping about, and it is the main reason a Viridian capsule costs more than a bag of dried leaf.
Whole Leaf and Standardised Extract Together
Each capsule holds 200mg of standardised olive leaf extract alongside 100mg of whole olive leaf. That pairing is deliberate.
The extract delivers the guaranteed oleuropein. The whole leaf brings the rest of the plant with it, the smaller compounds that sit alongside oleuropein in nature and that a concentrated extract leaves behind. Viridian builds most of its range this way, and sets the capsule in a base of alfalfa, spirulina and bilberry rather than the chalk and rice flour most brands use as filler.
Olive Leaf Extract and Blood Pressure: What Researchers Have Measured
A 2025 systematic review in Phytotherapy Research gathered the trials in people with raised or borderline blood pressure. At a gram of olive leaf extract a day, the pooled figures showed systolic pressure about 11.45 mmHg lower and diastolic about 4.65 mmHg lower.
The reviewers were careful, and so are we. Three trials met their standard, with fewer than three hundred people between them, so this is an encouraging signal rather than a settled case. They described olive leaf as a safe herbal option for people whose readings are creeping up.
Worth knowing before you buy: one capsule here supplies 300mg of leaf material in total, which is roughly a third of the daily amount in that analysis. If blood pressure is your main reason for looking at this, talk to our pharmacist first so you start with a clear idea of what to expect and how to measure it.
A Daily Antioxidant Habit
For most people who buy olive leaf, the everyday reason is simpler. It is a polyphenol taken once a day with food, the way you might take a green tea extract or a berry concentrate, as part of looking after yourself rather than as a response to a problem.
It is also a popular thing to reach for when the cold season comes round and everyone in the office is coughing, which is a long-standing traditional use of the leaf.
What Is in the Capsule
Olive leaf extract 200mg, standardised to 18% oleuropein, plus whole olive leaf 100mg, in a base of alfalfa, spirulina and bilberry, in a plant cellulose capsule.
Viridian formulates without palm oil, artificial fillers or genetically modified ingredients, and the capsule is suitable for vegans and vegetarians.
Who This Olive Leaf Extract Is For
Adults who want a daily plant polyphenol with a number on the label rather than a vague herbal promise. People building a Mediterranean-style routine and looking for the parts of it that come in a capsule. Households that want one bottle several people can share, since the manufacturer gives a children’s direction as well. And anyone who has been buying olive leaf tea or loose powder and would rather know exactly what they are getting each day.
How to Take It, Including Children
Adults take one capsule daily with food. That is the manufacturer’s direction, and taking it with a meal is the gentlest way.
For children aged six to sixteen, the manufacturer gives half a capsule daily with food, and the capsule pulls apart so you can tip half into juice or yoghurt. Six is the youngest age the manufacturer sets, and we would rather you asked us before giving it to a child so we can size it with you.
Polyphenols work quietly and cumulatively. Give it a couple of months, and if blood pressure is your reason, keep a written record of your readings so there is something real to look at.
Is Olive Leaf Extract Right for You?
Olive leaf is gentle and reviewers describe it as well tolerated. Our pharmacist is glad to go through it with you first if any of these apply:
- You already take medicine for blood pressure, so we can talk about how the two sit together and keep your doctor in the loop.
- You take medicine for diabetes, since olive leaf may have a mild effect on blood sugar.
- You are pregnant or breastfeeding, which the manufacturer asks you to check with a practitioner first.
- You are buying for a child, so we can confirm the age and the half-capsule amount with you.
Side effects are uncommon and mild, most often a little stomach upset, which usually settles when the capsule is taken in the middle of a meal.
Storing It
Keep the bottle closed in a cool, dry place away from direct sunlight, and out of reach of children. Do not exceed the recommended dose.

Frequently Asked Questions
What is olive leaf extract good for?
It is taken mainly as a daily antioxidant. Oleuropein, the polyphenol the leaf is rich in, is the compound researchers study, and a 2025 systematic review in Phytotherapy Research found meaningful blood-pressure reductions in people with borderline or raised readings at a gram of extract a day. Many people also reach for it in cold season, which is a long traditional use.
What does “standardised to 18% oleuropein” mean?
It means every capsule is tested to contain the same measured amount of the active polyphenol, rather than varying with the harvest and the weather. It is the main thing separating a reliable herbal capsule from dried leaf sold by weight.
Will it lower my blood pressure?
The research is promising rather than settled, and the amount matters. The pooled figures showing systolic pressure about 11.45 mmHg lower came from trials using about a gram of extract a day, and one capsule here supplies 300mg of leaf material. If this is your reason for buying, speak to our pharmacist so you start with realistic expectations and a way of measuring.
Can I take it with my blood pressure medicine?
That is a conversation to have with our pharmacist or your doctor first. Keep taking what you were prescribed and keep your review appointments; olive leaf is something to consider alongside treatment rather than in place of it.
How much is in each capsule?
200mg of olive leaf extract standardised to 18% oleuropein, plus 100mg of whole olive leaf, in a base of alfalfa, spirulina and bilberry.
Why both extract and whole leaf?
The extract guarantees the oleuropein. The whole leaf brings the rest of the plant with it, the smaller compounds that sit alongside oleuropein in nature and that a concentrated extract leaves behind. Viridian builds most of its range on that principle.
Can children take it?
The manufacturer gives a direction for ages six to sixteen: half a capsule daily with food, and the capsule opens so you can tip half into juice or yoghurt. Six is the youngest age they set. Ask us first so we can size it with you.
Is it the same as olive oil?
Related but different. Olive oil comes from the fruit; this comes from the leaf, which is richer in oleuropein than the fruit is. They complement each other rather than replace each other, which is why a Mediterranean diet uses both.
Do you sell olive leaf powder or tea?
Ask us what we have in stock. Loose powder and leaf tea are popular, and the difference is that a capsule tells you exactly how much oleuropein you are getting each day while loose leaf varies with the batch.
Is it suitable for vegans?
Yes. The capsule is plant cellulose and the base is alfalfa, spirulina and bilberry, with no palm oil, artificial fillers or genetically modified ingredients.
How long before I notice anything?
Give it a couple of months. Polyphenols work quietly and cumulatively rather than as something you feel on the day, so keep a note of your readings if blood pressure is the reason.
