How We Ranked

Because there’s no one-size-fits-all garlic product, we chose the products with the best track record from reputable brands. 

Ingredients – Each product should contain a good amount of the active ingredient and very limited additional ingredients, if any, at all.

Manufacturing Standards – Ideally, products are manufactured with good practices and safely stored for optimal quality and effectiveness.

Side Effects – Products should only contain ingredients that are generally considered safe for most people with little chance of causing discomfort or other undesirable effects. However, sometimes certain ingredients may cause discomfort and that’s one reason why it’s good to know which ones you can or can’t use.

User feedback is also sometimes a good way to determine the overall quality of a product.

Note: Consult with a medical professional before considering supplementing with garlic supplements if you suffer from health issues or are taking medications.

Benefits of Garlic

Garlic or allium sativum to be scientific, is closely related to the onion, chives, shallots, and leeks. It’s grown all over the world although China produces a large portion while the US accounts for a small percentage of garlic of which California is the main source.

And over three thousand studies have shown the positive effects of garlic for health purposes. In fact, it was used by the anxiety Egyptians, Greek, Romans, and others for this purpose. (1)

But due to the most recent evidence, it’s clear that the beneficial properties come from the sulfur compounds when the garlic is crushed or chopped. These substances include allicin which science shows is very potent, in addition to diallyl disulfide, and s-allyl cysteine. (2, 3)

But most products contain high amounts of allicin as the main compound for eliciting beneficial effects.

Improves and prevents common cold

Perhaps the most beneficial use of garlic is for the common cold due to its immune-boosting effects. One piece of scientific literature found that out of 146 volunteers who were given garlic or placebo, the former group had significantly fewer colds than the placebo group. (4)

The placebo group also has had symptoms much longer and individuals in the active group were less likely to get a cold and recovered faster if infected. It was concluded that the “allicin-containing supplement can prevent attack by the common cold virus.” 

But this may vary between individuals suffering from cold symptoms. 

May improve brain health

Alzheimer’s and dementia are associated with the aging population and so is cognitive function in general. It occurs when disease-causing free radicals cause oxidative stress in the body. But because garlic has antioxidants that fight off these free radicals, it’s likely to reduce the oxidative stress. (5)

Inflammation, high cholesterol, and hypertension also increase the risk factors for dementia and Alzheimer’s.  These also happen to be risk factors for cardiovascular disease. But because garlic can have positive effects on Inflammation, high cholesterol, and hypertension, dementia, and Alzheimer’s may improve as well. (6, 7, 8)

Can lower blood pressure 

Blood pressure is a risk factor for cardiovascular disease which is a fatal illness.

But garlic has shown to lower blood pressure in several studies. (9)

Still not convinced of its potency for this purpose? One study on patients with essential hypertension found that 600-1,500mg of garlic significantly reduced systolic and diastolic blood pressure reading more than a group that took atenolol (beta-blocker used to treat hypertension) and a placebo group over a 24-week period. (10)

May lower cholesterol 

Some research suggests that garlic may lower total and LDL (bad) cholesterol although there isn’t sufficient evidence to suggest it has an effect on HDL (good) cholesterol. (11, 12, 13)

Garlic can combat fatigue and increase endurance

Garlic is used to treat fatigue although the mechanism by which it may have positive effects is inconclusive. (1)

And in animal studies, the compounds in garlic have shown to increase endurance which is appealing to those who are usually involved in physical activity. 

The anti-fatigue properties are very promising and more studies are needed to extend upon what has been discovered so far. 

It smells and tastes amazing

Garlic is definitely not for everyone. But for those who do like it, the aroma of cooking with it is a bit heavenly not to mention it adds a lot of flavor to any dish. It’s also very low calorie and makes for the perfect addition to any foods that you can use it in combination with.

Who Should Buy Garlic Supplements?

Based on the provided studies and what we know about the beneficial, health-supporting properties of garlic,  healthy people who follow a health regime should consider supplementing with garlic. 

It’s good for heart health which is crucial for longevity, immune system health which is especially important currently to protect yourself against the current health crisis, and other health factors as we’ve detailed.

 There are no negatives to consuming a healthy dose of garlic!

How Do I Pick A Good Garlic Product For Me?

There are plenty of great garlic products on the market. However, some people have better experiences with certain products compared to others. 

You can determine which product to choose based on the information we’ve provided. Also, you may want to choose a product from a company that you’ve had good experiences with. We also recommend reading user feedback to see what others have experienced with a product as well. 

Keep in mind that different products may vary in the amount of garlic contained in each product. Although, most garlic supplements typically have a similar amount of around 1,000mg garlic extract. That’s pretty indicative of this being a safe and therapeutic dose. 

So, anything in this range is good-to-go. 

Another important thing to note is that some additional ingredients may not react well with some individuals including soy and added ingredients used in the capsules. And some products aren’t entirely plant-based which is a definite dealbreaker for many.

Don’t be afraid to inquire and ask questions to ensure you choose a product that’s best suited for your needs.

Does Garlic Have Side Effects? 

Garlic can cause allergic reactions for some people. It can also thin blood and increases the chances of bleeding. That’s why it’s best to avoid consumption in combination with certain medications that already thin the blood such as Aspirin for example. 

It’s also possible that garlic causes digestive discomfort, vomiting, nausea, gas, body odor, and the unpleasant breath is a no brainer.

Generally, though, garlic is safe and shouldn’t cause any side effects.

How Much Garlic Should I Consume?

According to the American Academy of Family Physicians…

The effective dosage of garlic has not been determined. Dosages generally recommended in the literature for adults are 4 g (one to two cloves) of raw garlic per day, one 300-mg dried garlic powder tablet (standardized to 1.3 percent alliin or 0.6 percent allicin yield) two to three times per day, or 7.2 g of aged garlic extract per day”. (14)

We recommend following the dosing instructions provided on the product label. Otherwise, if you eat a lot of garlic then take the minimum dosage. 

Is There A Best Garlic Supplement?

Everyone will have a preference. Some may prefer oil, and others, capsules/tablets. As mentioned previously, you may find that something works better for you than other similar products. Go with any of the reputable supplement brands and weigh the pros and cons. 

If you want the reassurance of potency and purity, opt for a supplement that is lab-tested and GMP compliant to ensure you’re getting the actual dose of ingredients listed on the product’s label.
