Garlic is low in calories and rich in vitamin C, vitamin B6 and manganese. It also contains trace amounts of various other nutrients.

3 – Garlic Can Combat Sickness, Including the Common Cold

Garlic supplements are known to boost the function of the immune system.

One large, 12-week study found that a daily garlic supplement reduced the number of colds by 63% compared to a placebo (Source). The average length of cold symptoms was also reduced by 70%, from 5 days in the placebo group to just 1.5 days in the garlic group.

Another study found that a high dose of aged garlic extract (2.56 grams per day) reduced the number of days sick with cold or flu by 61% (Source).

4 – The Active Compounds in Garlic Can Reduce Blood Pressure

High doses of garlic appear to improve blood pressure for those with known high blood pressure (hypertension). In some instances, supplements may be as effective as regular medications.

Garlic supplements seem to reduce total and LDL cholesterol, particularly in those who have high cholesterol. HDL cholesterol and triglycerides do not seem to be affected.

7 – Garlic May Help You Live Longer

Given the beneficial effects on important risk factors like blood pressure, it makes sense that garlic could help you live longer.

The fact that it can fight infectious disease is also an important factor, because these are common causes of death, especially in the elderly or people with dysfunctional immune systems.

8 – Athletic Performance Might Be Improved with Garlic Supplements

Garlic was one of the earliest “performance enhancing” substances. It was traditionally used in ancient cultures to reduce fatigue and enhance the work capacity of laborers. Most notably, it was given to Olympic athletes in ancient Greece (Source).

People with heart disease who took garlic oil for 6 weeks had a 12% reduction in peak heart rate and better exercise capacity (Source).

However, study results are mixed, as one study on nine competitive cyclists found no performance benefits (Source).

9 – Eating Garlic May Help Detoxify Heavy Metals in the Body

At high doses, the sulfur compounds in garlic have been shown to protect against organ damage from heavy metal toxicity.

A four-week study in employees of a car battery plant (excessive exposure to lead) found that garlic reduced lead levels in the blood by 19%. It also reduced many clinical signs of toxicity, including headaches and blood pressure (Source).

Three doses of garlic each day even outperformed the drug D-penicillamine in reducing symptoms.


Given the delicious taste of garlic and the health benefits, adding garlic to your diet should be a no-brainer! Peeling fresh garlic can be tricky, but this quick 2 minute video shows how you can easily peel multiple cloves in less than 30 seconds.
