Supplements of garlic lowers blood pressure, systolic and diastolic (the top and bottom numbers of a reading) by 6.7 and 4.8 mmHg, respectively, according to a study of randomized controlled trials (RCTs), the gold standard in research.

The 8–12 week studies included in the study gave participants 188–2,400 mg of garlic powder supplements or aged garlic extracts per day.

Several additional recent studies back up these findings, with several claiming blood pressure drops of 2.5–11.2 mm Hg after consuming 600–2,400 mg of garlic powder per day for 8–24 weeks.

How Does Garlic Lowers Blood Pressure Work?

Garlic’s major active ingredient, allicin, is thought to be responsible for the herb’s blood pressure-lowering qualities.

Allicin’s properties limit the synthesis of angiotensin II, making it simpler for your blood to flow freely and lowering your blood pressure.

Allicin also appears to boost the formation or availability of hydrogen sulfide and nitric oxide, two important chemicals for blood pressure regulation.

Garlic’s anti-inflammatory and antioxidant characteristics, according to experts, may also contribute to garlic lowers blood pressure rises.


Garlic has been used to prevent and treat disease for over 5,000 years, with few reports of negative side effects.

Garlic supplements have been shown to be extremely safe in the majority of research to date. Garlic breath, taste, and body odor are the most commonly reported negative effects.

Stomach distress, gas, reflux, or abdominal discomfort are also prevalent, but these are usually minor concerns.

Hypersensitivity, headaches, dry mouth, coughing, hot flushes, mouth ulcers, and sleepiness are all possible adverse effects, but they are uncommon.

When using garlic powder supplements or aged garlic extracts, side effects tend to be more likely when ingesting significant amounts of garlic.

When taken with anti-coagulant medicine, a high consumption of garlic, whether through food or supplements, can thin the blood and raise the risk of bleeding. If you’re on any drugs, check with your doctor before substantially increasing your garlic consumption.
