Frequently asked questions (FAQs)

Finding the right supplements can often lead to a lot of questions. Don't worry though because we've answered some of the most frequently asked queries surrounding garlic supplements right here.

What do garlic supplements do?

Richard Rivlin wrote in The Journal Of Nutrition that the Greek physician Hippocrates prescribed garlic for respiratory problems, parasites, poor digestion, and fatigue. In fact, the original Olympic athletes were said to once use garlic as a 'performance enhancing' agent, but why is this the case?

Well, garlic has been linked to reducing fatigue. One study by Kyung A Hwang et al. using rodents found that low-temperature-aged garlic improved exercise performance and, as a result, may be an effective pharmacological anti-fatigue agent like some of the best creatine supplements around.

The potential benefits, however, don't stop there. Garlic has also been linked to protecting against illness, specifically the common cold. A large 12-week study by Josling supports this as they found consuming a daily garlic supplement reduced the number of colds by 63% compared to the study's placebo group.

Moreover, garlic is connected to improving your cardiovascular health. Several studies, including one of particular note by Ried et al., have demonstrated garlic supplements reduce blood pressure in those who are predisposed to the condition. Research has also found garlic to lower LDL cholesterol.

As a result, we feel garlic supplements are worth considering due to the sheer number of potential health benefits associated with adding garlic to your diet.

How much garlic should you consume in a day?

How many garlic capsules or how much garlic you should consume in a day will vary from person to person depending on several biological factors such as size and sex.

However, according to Ellen Tattelman writing for the American Family Physician, the general recommended allowance for adults is around 4g of raw garlic per day, one 300mg dried garlic powder tablet two to three times per day, or 7.2g of aged garlic extract per day.

Tattelman does also state that the effective dosage of garlic has not been determined in literature. Therefore, these specific quantities may not prove effective for everyone.

When should you take garlic supplements?

According to the Cleveland Clinic, the best time to take most vitamins and supplements is on an empty stomach with a glass of water.

This should help ensure your body absorb and metabolise them, thus allowing the garlic to take effect a little quicker.

That said, if you find taking garlic supplements without food upsets your stomach, then you can still take them whilst you're full, they just might take longer to kick in.

Ultimately, our main advice would be to pick a time or times that suit you and your stomach and stick to it each day to ensure your body is receiving a consistent amount of the supplement.

Are garlic supplements safe?

According to the NCCIH, consuming garlic in moderate amounts through food is probably safe for most individuals. However, it is unclear whether taking garlic supplements is safe.

Nevertheless, various studies have found that garlic supplements are generally safe, with the most commonly reported side effects being unpleasant taste, bad breath, and body odor. That said, some research suggests that garlic supplements can cause stomach discomfort, although such complaints are usually minor.

If you are taking any blood-thinning medication, it is recommended by the NCCIH that you consult with a healthcare professional before taking garlic supplements, as garlic may increase the risk of bleeding.
