Garlic and Blood Pressure: Can This Kitchen Staple Lower Your Reading?
Can eating garlic really lower your blood pressure? We explore the science behind garlic and hypertension, the best ways to eat it, and how to fix that garlic breath afterwards.
If you are looking for natural ways to lower blood pressure, you may have heard that garlic could be the answer. But is there any truth to this old kitchen remedy, or is it just a myth? Let us peel back the layers and find out.
The Science: Does Garlic Actually Lower Blood Pressure?
The short answer? Yes, probably.
A major review of 12 clinical trials found that garlic supplements can lower systolic blood pressure (the top number) by an average of 8.4 mmHg.
While this might not sound like a lot, it is actually quite significant. According to the NHS, even a small reduction in blood pressure can lower your risk of stroke and heart disease.
💡 What the Research Says
Studies suggest that the active compound in garlic, allicin, helps relax blood vessels—similar to how some blood pressure medications work.

See What's Inside →How Much Garlic Do You Need?
Here is where it gets a bit tricky. To get the benefits seen in the research, you would need to consume a fairly large amount of garlic:
Daily Target for Blood Pressure Benefits:
- 2–4 fresh garlic cloves (crushed or minced), OR
- 600–1200mg of aged garlic extract supplements
Important: The way you prepare garlic matters. Crushing or mincing garlic and letting it sit for 10 minutes before cooking activates the allicin.
The Best Ways to Add Garlic to Your Diet
If you want to harness garlic's blood pressure benefits, here are some easy ways to add it to your meals:
Crush It Raw
Add crushed raw garlic to homemade salad dressings. This preserves the most allicin.
Roast It Whole
Roasting a whole garlic bulb creates a milder, sweeter flavour you can spread on toast.
Add It Last
When cooking, add minced garlic in the final few minutes to retain more of its active compounds.
Try Supplements
If you are not a fan of the taste (or the breath!), aged garlic extract supplements are a convenient alternative.
What About the Garlic Breath?
Let us address the elephant in the room. Yes, garlic breath is real. But there are ways to minimise it:
- Chew fresh parsley or mint leaves – The chlorophyll helps neutralise the smell.
- Drink green tea – The polyphenols can help deodorise your breath.
- Eat an apple – The enzymes in raw apple help break down the smelly compounds.
- Use aged garlic supplements – These are specifically processed to be odourless.
Warning: If you are taking blood-thinning medications (like warfarin), talk to your GP before increasing your garlic intake, as it can enhance the effects of these drugs.
