What are the Benefits of the Best Olive Leaf Extract Supplements?

Many know the olive tree for its fruit and numerous health applications. However, its leaves are also gaining ground for their potential health benefits.

The leaves can be sold as-is or extracted in capsules, soft gels, powder, tinctures, and consumed as supplements. But what exactly are the benefits you can derive from the best olive leaf extract supplements?


Olive leaf is showing excellent potential at helping controlling type 2 diabetes.

Studies done on animals show it reduces their digestion of starch and its absorption in their bodies. That suggests it may be terrific in regulating blood glucose levels in humans or even prevent the disease from taking hold.

There was also independent research on olive leaf extracts in treating diabetes. Subjects with type 2 diabetes who participated received either olive leaf extracts or placebos for a programmed period.

Those who received the extracts showed marked improvement in their blood sugar levels compared to those in the control group.


In a study done on rats in 2015, olive leaf extracts lowered overall cholesterol levels, notably “bad cholesterol” HDL.

Rats that received the extract and those given regular medication showed substantial improvement compared to the control group that didn’t receive any treatment.

In the same year, there was research where volunteers who suffered from hypertension received oleuropein olive leaf extracts. By the end of it, not only did it reduce their blood pressure significantly, but also their triglyceride and LDL levels.

High Blood Pressure

Besides other factors, such as obesity, diabetes, and smoking, high cholesterol is another one that can cause hypertension.

In European studies in 2016, 60 volunteers with stage one hypertension received either olive leaf extracts or a placebo for six weeks.

Results showed considerable reductions in total cholesterol, including LDL and blood pressure for those who took the supplements.

Provides a Boost to the Immune System

Although research is limited to cell cultures , olive leaf extract proved effective against influenza, mononucleosis, rotavirus, and herpes . However, there’s still no research done to validate such benefits on humans.

Who Should Buy Olive Leaf Extract Supplements?

Obese People

High cholesterol, hypertension, diabetes, and obesity often go hand in hand. The best olive leaf extract supplements can help deal with cholesterol linked to high blood pressure.

Check our TDEE Calculator to check your Ideal Weight.

People Who Suffer from Hypertension

People with high cholesterol, particularly those with increased LDL and triglycerides, tend to have high blood pressure. Regularly taking olive leaf extract supplements may reduce the blood’s overall cholesterol levels, including HDL and triglycerides.

People with Type 2 Diabetes

According to clinical studies done on animals and humans, olive leaf extracts may reduce the digestion of starch, so the body absorbs less glucose. It leads to the reduction of blood sugar, which is beneficial for those with type 2 diabetes.

How Do I Pick the Best Olive Leaf Extract Supplements?

Ideally, you’d pick one with at least 18% oleuropein, which is the most beneficial substance in the extract. However, it’s not as straightforward as that.

You also have to look at the extracted content in milligrams to determine the oleuropein’s actual weight. 20% of 500mg would mean 100mg of oleuropein content. Sometimes, there’s no indication of this on the label, so you have to be wary.

50-100mg is sufficient for most needs. Anything less would mean additional doses per day. Also, choose companies that have certified GMP manufacturing facilities.

You should take a close look at the ingredients used to ensure they’re non-GMO (Genetically Modified Organisms). Don’t get those with artificial materials and preservatives, and go for 100% vegetable to be safe.

Ensure they’re free of gluten and soy. Choose only those with hypoallergenic ingredients to avoid any complications.

Side Effects

Although there are no well-documented side effects in using olive leaf extract, some people had headaches, upset stomach, or felt dizzy after taking the supplements.

Women must never use it while they are nursing or pregnant. Diabetic people using insulin should avoid the product. It’s also inadvisable for use by those with low blood pressure.

Stop taking it and consult your doctor as soon as you feel any ill side effects.

Recommended Dosage

Although there aren’t any official guidelines on dosing, research suggests that 500-1,000mg per day is sufficient. However, you have to consider the percentage of the oleuropein content and its weight in milligrams.

Often, the manufacturer divides the serving 2-3 times daily after meals or with water. It’s best to follow the recommended servings and any warnings on the label.


What is olive leaf extract?

The extract from olive leaves isn’t the same as olive oil. There’s an active component in it called oleuropein, which provides the most benefit.

Oleuropein is an antioxidant with anti-inflammatory properties. Research results show it can also reduce cholesterol and blood sugar.

Is olive leaf extract safe?

As long as you take it within 500-1000 mg, it should be fine.

However, pregnant or nursing moms, are hypoglycemic or have low blood pressure shouldn’t use olive leaf extracts.

How do you take olive leaf extract?

Typically, companies that sell them have recommended dosages on their bottle’s label. It will tell you how many capsules you can take per day.

Your best bet would be to ask your doctor.

How do you store olive leaf extract properly?

It’s best to store a bottle somewhere cool and dark such as a ref or cupboard. Doing so would help prolong the capsules’ shelf life and maintain their quality and potency.


There’s still too little research to validate the claims on all the health benefits derived from olive leaf extracts. After all, it’s still considered a dietary supplement by the FDA and not a medicine.

Nevertheless, studies have demonstrated its potency in reducing cholesterol and blood glucose and its anti-inflammatory properties.

It’s also proper to point out that users who buy these products consistently give them high marks. It means that the supplements are working for them and helping with their health issues.

That’s why take it from those buyers and purchase only the best olive leaf extracts supplements. If it could work for you, then why not?

However, no one should use it for self-treatment instead of seeking standard medical care. Moreover, you must consult with your doctor first before purchasing or using any of them.
