1. Sundown Naturals – Odorless Garlic Extract
Test Winner: 1. Sundown Naturals – Odorless Garlic Extract

Almost 2500 years ago, Hippocrates, a Greek physician of his time, would use garlic to treat various illnesses. In the 21st century we are probably a few centuries late in finally understanding and believing in the power of garlic, but it’s better late than never.

Garlic is a natural antibiotic famous for its potency in combating flu and common cold symptoms, among other health problems. It is also great in supporting cardiovascular health and wellbeing to improve the heart and circulatory function, which can be great for those who are older and want to make sure that their heart is as healthy as possible.

As opposed to crushing the garlic (which destroys the active ingredient Allicin), cutting the garlic into slices is more beneficial. However, not a lot of us are fans of chewing on raw garlic just to get its benefits. Although garlic is amazing in its raw form at helping our body combat virus and infection it can be pungent and leave a lingering taste and smell in the mouth.

Also, having to take the time to source out garlic cloves without knowing whether or not the allicin in it is active is another factor to consider. Experiences like these are the reasons that some people might begin their search for the best garlic supplement out there.

13 Best Garlic Supplements

1. Sundown Naturals – Odorless Garlic Extract

1. Sundown Naturals – Odorless Garlic Extract

Garlic Extract from Sundown is probably something we'd recommend to a lot of people. Unless you hate swallowing pills, they will contain some of the best garlic extract for you, free of extra ingredients that can cause problems.

Expand to see more

The price is low for a 250-softgel pack; this one can last you two months with four softgels a day. That's the first problem, though: remembering when to have your garlic extract four times a day while not eating it too late at night.

Cheers to the lot who have trouble finding non-GMO garlic extracts, as this one has four ingredients in it: garlic, soybean oil, gelatin, and vegetable glycerin. And did we mention that it's odorless? Yes, using it long-term does not make you walking garlic. It uses a cold processing method to ensure that odors are eliminated.

To be honest, this is hands down the most effective supplement among the ones reviewed here, as you can see in the pros and cons below.

Pros
  • Odorless from cold processing method
  • No garlic side effects (heartburn, aftertaste, burps)
  • Non-GMO
  • Dairy-free
  • Gluten-free
  • No sugar
  • No artificial color, flavor, or sweetener
  • No preservatives
  • Made in the US
  • Excellent value for money
Cons
  • Contains soy; some may experience allergic reaction from soy
  • Four times a day, that's a lot of softgels to take
  • Gelatin, not for vegetarians

2. Kyolic – Garlic Formula 100

2. Kyolic – Garlic Formula 100

So far over the period of our use of Kyolic – Garlic Supplement, there has been no aftertaste and no body odor; this is the perfect garlic combination. Kyolic used aged garlic extract in the form of powders and encapsulated with gelatin, which is the usual standard for capsules.

Expand to see more

As we will mention later here, aged garlic extract is more abundant in antioxidants and antifungals. Yes, this is due to the method of processing. Note that these organic garlic pills don't rely on allicin, as some other products do.

They age the garlic in aqueous solution for 20 months, which removes the odor while at the same time buffing the antioxidants. It enhances immunity considerably, one of their main selling points. Their component then turns into something similar to allicin, called SAC (S-allyl cysteine).

SAC is very soluble. It is 98% absorbed by our body. (1) This wholefood form, Kyolic, is the most honest and reliable garlic supplement, as it is very active and does what it says. However, Kyolic is not dairy-free, and the capsules have a strong smell. The content of these natural garlic pills is vegan, but the capsule is comprised of gelatin (beef). Kyolic does have other products that are strictly vegan, right down to the capsule materials.

Pros
  • Odorless garlic supplement
  • High antioxidant levels compared to other supplements
  • Antifungal
  • Free of yeast, sugar, and gluten
  • Free of artificial colors or flavors
  • No preservatives
  • Made of 100% organically-grown garlic from California
Cons
  • Strong-smelling capsule
  • Capsule contains whey (dairy)
  • Non-vegan
  • Higher price compared to other products

3. BRI Nutrition – Odorless Garlic

3. BRI Nutrition – Odorless Garlic

BRI heavily markets their garlic supplement at a competitive price. The great thing about this one is that it does not merely contain garlic, but also other healthy ingredients, such as parsley seeds and chlorophyll.

Expand to see more

Due to its soft gel casing, it is sensitive to heat and should not be left long in the mouth, otherwise it will melt. Several consumers have also complained about an aftertaste, which should be resolved if consumed with enough water (8 oz). The product manufacturer also recommends taking the supplement with a meal, which may help the softgel to go down the throat faster than it will melt.

Aside from that, BRI's garlic supplement is excellent, because it is odorless and easy to swallow. It also does not cause heartburn or acid reflux. GMP certification also reassures us that the quality of the product is excellent. It is important to note that this garlic supplement does not contain allicin, but rather the base products. Keep in mind that allicin is only gained through the reactions of alliinase and alliin when consumed.

This garlic supplement is a good deal when you realize that the 120-softgel pack is for two months’ use. It's considerably cheap and still contains the intended ingredients plus several other beneficial substances inside.

One thing that we like from the BRI Nutrition Odorless Garlic is that you only need to swallow two softgels once a day. It also comes with parsley seeds and chlorophyll, so that's another plus.

Pros
  • Odorless garlic supplement
  • High potency garlic-based formula
  • Enhanced with parsley seed oil and chlorophyll
  • Powerful antioxidant
  • Does not cause heartburn
  • Does not cause garlic breath
  • Made in the US
  • High value for money
Cons
  • Contains soybean oil
  • Non-vegan (capsule made of gelatin)
  • This product is manufactured and packaged in a facility which may also process milk, soy, wheat, egg, peanuts, tree nuts, fish, and crustacean shellfish

4. Enzymatic Therapy – Garlinase 5000

4. Enzymatic Therapy – Garlinase 5000

The total opposite of Kyolic's Aged Garlic Extract is Enzymatic Therapy’s Garlinase. It is one among the rare options which have actual allicin in them. These supplements are a little bit different from others in that they contain direct allicin substance in them and have a higher dose in a single pill.

Expand to see more

The idea of Garlinase, in our opinion, is for those who rarely have garlic in their daily meals to still have enough intake of allicin. That is why it contains 5,000 mcg of allicin in a single pill.

Enteric-coated pills ensure that they melt in time for the intestine to process but are not destroyed in the stomach. Now, for several reasons, this is a useful, yet not that big of an advantage compared to the others. Kyolic and BRI have also reported customers not having garlic breath after (properly) swallowing the pills.

The rule is the same with every liquid-coated supplement: do not bite or chew or leave them for too long in your mouth. Yes, they will melt, and you will have condensed garlic liquid on your tongue and all over your mouth. If you drink them with enough water or eat them with meals, this will reduce the possibility of garlic smell coming up your throat. This is no big deal, as it encourages to drink more water.

Other great things about the product are that it is free of lots of allergens, such as soy or dairy products. So, for any of you who want to reduce allergy reactions, this can be the perfect supplement for you.

We are more interested in discussing the other ingredients included in this fresh garlic supplement. You will notice some modified substances and also silicon dioxide. Now, for some of you, it becomes pretty clear that this product contains GMO cellulose. On the other hand, what is silicone dioxide? It sounds like a chemical ingredient in our supplement! Actually, no, it's technically natural.

It’s other name is silica – yeah, the one that you see in many products to keep them from getting damp. You know that with Nature's Bounty, the product melts quickly, but with silica, this can keep it dry, and at the same time, helps it go down the throat, through the stomach, and melt in the intestines.

So, is silica dangerous? From the conclusion of multiple studies, no one knows for sure. There are mixed results of positive and negative reactions from ingesting silica, but in reality, we don't eat much silica in our daily life.

You have to be someone who works in the mining field who stands around quartz and other dangerous exposures for 6-10 hours a day to worry about it. In small amounts, no one has been reported to show a hazardous reaction, although, yes, silica packs always come with the warning to not be eaten.

Pros
  • Odorless
  • Enteric-coated tablets to reach the place that needs garlic the most
  • One pill a day (woohoo!)
  • Soy-free
  • Dairy-free
  • Gluten-free
  • Vegetarian-friendly
  • No garlic side effects (heartburn, aftertaste, burps)
  • Contains allicin, the main active compound in garlic
Cons
  • Contains GMO substances
  • Includes silica, which some people may not feel like having in their food

5. Nature’s Bounty – Garlic Extract

5. Nature’s Bounty – Garlic Extract

What makes Nature's Bounty Garlic extract different is their processing method. Cold processing retains the content of garlic but eliminates the odor.

Expand to see more

What we are pretty concerned about is the actual content of allicin. After going through lots of questions and reviews, no one knows for sure if this has any allicin concentrate or alliin and alliinase, which make it possible to produce allicin. Although it does help in reducing blood pressure as well as boosting the immune system when battling a cold or other common diseases, so that's probably a good sign.

Nature’s Bounty Garlic Supplement is another product that works well for people who have trouble swallowing things. The softgels are tiny and transparent. After swallowing, there is no odor, no burping of garlic bubbles or heartburn, just a pill with goodness inside it. However, it does instruct the customer to take it four times a day, which means they must be consumed in a very short span of time, considering garlic and its supplement form should not be consumed at night or before bedtime.

Some may want to pay attention to the ingredients of the capsule itself. If you have allergies to soybean or if you're a vegetarian, this product has gelatin and soybean oil in it. Due to this fact, it melts when you store it in a heated place, or even during the delivery.

Another thing we'd like to point out is that this is very cheap. Probably because it merely contains garlic with no preservatives or any artificial coloring or GMO stuff in it. Simply garlic: 3 packs for 75 days of usage.

Pros
  • Odorless from the cold processing method
  • Rapid-reaction softgels
  • No garlic aftertaste or body odor
  • Easy to swallow
  • Non-GMO
  • Gluten-free
  • No artificial compounds (no artificial color, flavor, sweetener)
  • No preservatives
Cons
  • Have to take four times a day
  • Store pills in cool places or they will melt and the content will spill out

6. Solgar – Garlic Oil Perles

6. Solgar – Garlic Oil Perles

Solgar Garlic Oil Perles Capsules are a natural garlic supplement that support cardiovascular health and immune functions. Solgar is a brand that has been established since 1947, and they have an outstanding reputation for quality products.

Expand to see more

The Solgar Garlic Oil Perles Capsules are free from gluten, wheat, and dairy, so they are suitable for a wide range of dietary requirements; however, they are not vegetarian or vegan friendly, due to the gelatin that creates the gel consistency of the capsule.

The serving suggestion for the Solgar Garlic Oil Perles Capsules is one capsule twice a day, giving you 250 servings in each container, and at least 125 days of capsules, so the Solgar Garlic Oil Perles Capsules should last for over four months, which is excellent value for money.

The Solgar Garlic Oil Perles Capsules are one of the best garlic supplement options on this list, as they are totally natural, great value for money, and have a high potency, so there is no need to take an excessive amount of capsules during the day.

Pros
  • Supports cardiovascular health
  • Boosts immune functions
  • Potent formula
Cons
  • Not suitable for vegetarians and vegans

7. Jarrow Formulas – Garlic and Ginger

7. Jarrow Formulas – Garlic and Ginger

The Jarrow Formulas Garlic and Ginger capsules are very different to other capsules on this list, as they use ginger to enhance the capsules.

Expand to see more

Ginger and garlic are a harmonious combination that help the body to absorb both herbs and achieve all of the benefits possible from them.

The ginger is naturally dried rather than heat-dried, which gives the supplement a lot more of the benefits.

The Jarrow Formulas Garlic and Ginger capsules are taken one to two times per day, and only one capsule is taken, so there are 100 capsules in each container, which means the Jarrow Formulas Garlic and Ginger capsules should last for around six weeks.

The Jarrow Formulas Garlic and Ginger capsules are not vegetarian or vegan friendly, however, due to the gelatin content of the capsules, yet they are also free of many other allergens, so they are suitable for more difficult and specific dietary requirements.

Pros
  • Naturally dried 
  • Allergen-free
  • Quality ingredients
Cons
  • Not suitable for vegetarians and vegans

8. Natural Factors – GarlicRich

8. Natural Factors – GarlicRich

The Natural Factors GarlicRich Garlic Concentrate Capsules are an odorless, super-strength capsule with around eight cloves of garlic to each capsule, which is a hugely strong garlic supplement.

Expand to see more

The Natural Factors GarlicRich Garlic Concentrate Capsules are formulated to be very easy to digest and absorb into your body, so you will get the most health benefits possible out of your garlic supplement.

All of Natural Factors’ products are manufactured specifically to meet the Government of Canada’s Good Manufacturing Practices, which is among some of the highest health standards in the world, so you can be assured that you will be totally safe with the Natural Factors GarlicRich Garlic Concentrate Capsules.

The Natural Factors GarlicRich Garlic Concentrate Capsules are not vegan, however, as they are made with gelatin to give the capsules a gel consistency. They are dairy, gluten, and yeast free, though, so they are suitable for a wide range of dietary requirements.

Pros
  • High potent formula
  • Only one capsule per day
  • Gluten free
  • Dairy-free
Cons
  • Not suitable for vegetarians

9. Now Foods – Garlic Oil

9. Now Foods – Garlic Oil

Now Foods has been manufacturing healthy supplements for over 50 years now. Garlic oil is another healthy supplement of theirs. However, there is a reason the manufacturers did not add “odorless” to its name. It does leave a bit of garlic aftertaste. A few burps, if you don't mind. So, if you hate garlic breath, you will not love this one. If you wish to reduce the smell of garlic after consumption of the garlic supplement, follow the instructions recommended by the manufacturer (to eat the softgels with meals).

Expand to see more

Aside from that, NOW is a company that has been known to be committed to non-GMO and has attained GMP certification for this garlic oil. GMP processes eliminate possible allergens, so for those who fear allergic reactions, this is an excellent choice with just a little garlic breath.

An important note is that this is for adults only, so you should not try to feed children with this. If you do, consulting with a doctor first would be best.

Now, the critical part: allicin. The product claims that it extracts bulb of Allium Sativum, or the Latin name for garlic. Each serving, then, contains 9 mg of garlic oil concentrate, which is equivalent to 4.5g of whole clove garlic. The question is, does it still retain all the necessary alliin and alliinase? Or is it able to 'freeze' allicin in it?

Happy to say, regardless of the fact, it still proves to be very potent. The strong smell of garlic suggests that allicin, a deciding component in garlic's scent, is in there somewhere.

Pros
  • Will not leave you with body odor
  • Potent garlic oil
  • Dairy-free
  • Gluten-free
  • No sugar
  • Preservative- and colorant-free (which explains the different colors that are on the pills)
  • GMP certification
  • Made in the US
Cons
  • Not odorless, will leave garlic taste, and causes burps
  • Contains gelatin, non-vegan

11. Oregon’s Wild Harvest – Garlic

Oregon’s Wild Harvest Garlic Supplements are made from organic garlic herb and are carefully processed to produce a high-quality garlic supplement, which is certified by Oregon Tilth.

12. Solaray – Organically Grown Garlic

12. Solaray – Organically Grown Garlic

Solaray Organically Grown Garlic is among the most affordable and potent garlic supplements out there, and we say this with a healthy reason: it does leave you with garlic aftertaste. Although, it's not so bad and won’t last for a day.

Expand to see more

Solaray is a brand that has received numerous certifications, from being a quality retainer to a hater of the artificial (as I call it). Their products are free of any artificial coloring, preservatives, or anything of the sort.

The garlic is organically grown and harvested. The end product has no other fillers, so it is free of gluten, dairy, as well as being vegetarian-friendly.

However, if you're wondering if this is non-GMO, that's a debatable topic. The supplement has not yet gained the non-GMO certification, but it does indeed use organically grown garlic. If everything written on the label is true, then yes, this product is supposed to be non-GMO.

Pros
  • Affordable
  • Organically grown garlic
  • Dairy-free
  • Soy-free
  • Gluten-free
  • Vegetarian-friendly
  • No preservatives or artificial substances
Cons
  • Potent garlic smell, indicating unprocessed garlic
  • Leaves you with garlic smells, although this can be different for each person
  • Can sometimes leave you with a stomachache, so make sure to eat it with meals
  • Big tablets
