2018's 10 Best
Garlic Supplements

Myths perpetrate every part of our world, and unfortunately they impact the way we view and manage our health. Supplements are sold as “magic fix-all’s” that will cure all your problems because of one ingredient or another. But most of these myths do have some truth to them as well. It is important, especially when looking to improve overall health, to decide which myths are true and which are fantasy.

So read on to discover the myths and facts about garlic and garlic supplements!

Allicin Use is a Myth

Allicin dictates the discussion about most garlic supplements, and for that reason it must be the first myth we bust. Allicin does have the chemical properties to be stronger than penicillin, clear up cholesterol, and improve blood glucose levels, but it does not have the stability to be of any use.

It is impossible to contain allicin in a supplement or pill, it will dissolve in blood after a few minutes with little to no impact on your system, and there is no guarantee (or chance) that the compounds needed to create allicin will convert to allicin.

Nearly every garlic product you encounter will argue that it contains high levels of allicin, or at least allinaise, which is the compound needed to create allicin. But according to a study from a group who wrote on the “Intake of Garlic and Its Bioactive Components Recent Advances on the Nutritional Effects Associated with the Use of Garlic as a Supplement”:

“Within a few minutes after adding allicin to blood, it can no longer be detected. Allicin cannot be detected in the blood or urine after the ingestion of raw garlic or pure allicin. Although freshly crushed garlic may contain limited amounts of allicin, no commercially available processed garlic preparations contain allicin. The acidity of the stomach would be expected to prevent the conversion of allium to allicin. . . These findings clearly indicate that allicin does not contribute to the in vivo effects of garlic.”[11]

Garlic is capable of improving many things to do with human physiology, but that is not due to the “high levels” of allicin in whatever product you use. It is typically the compounds that are created from allicin that provide the best benefits to your system.

Harunobu Amagase wrote in his book, “Clarifying the Real Bioactive Constituents of Garlic”:

“Compounds in garlic work synergistically to produce various effects, but, because of garlic’s chemical complexity, processing methods yield preparations with differing efficacy and safety. Although thiosulfinates such as allicin have been long misunderstood to be active compounds due to their characteristic odor, it is not necessary for garlic preparations to contain such odorous compounds to be effective, and they decompose and disappear during any processing.” [12]

So before you bounce off this site to find a better product, why don’t you take a look at the rest of the facts and myths regarding garlic. You might find just what you’re looking for. See the #1 Garlic Supplement now

Garlic Purifies Blood

We can thank old wives tales for this myth, and for the semi truth here. Garlic is a great supplement for improving overall cardiovascular health, several of its sulphuric compounds are directly related to improved vascular health. This includes improving cardiac tissue, red blood cells, atherosclerosis, vasorelaxation, blood pressure, platelets, triglycerides, and cholesterol. But there is nothing about it that literally purifies the blood (for that you should look to the use of a liver.)

A Clove Of Garlic A Day Keeps Heart Attacks AT Bay

Heart attacks are really only caused directly by two things, coronary artery disease, and blood clots. Both of which are caused by a buildup of plaque and atherosclerosis, which is the stiffening and damage of arterial walls.

Including foods in your diet that prevent that is essential regardless of age or overall health. Garlic can be used to reduce the plaque buildup in blood vessels and arteries, this is important for improving blood flow and preventing heart attacks. See the #1 Garlic Supplement now

It is also great for vasorelaxation, which is where it lessens the stress on blood cells walls and lets them flow more freely. This all improves your vascular health and can help blood pressure medication work properly.

Great for Lowering Cholesterol:

Lowering Cholesterol is essential to overall heart health, as well as preventing heart attack. And especially where so much of the modern diet [provides an automatic boost] in bad cholesterol (HDL) it can become especially difficult to maintain a healthy blood stream.

Garlic has improved this in lives for thousands of years, we can look to the use of garlic in the mediterranean diet as a factor for why Italians and Greeks have far better cholesterol levels despite eating high fat and carb diets.

So let’s get down to the science here, the first step that you get to look at is the effect of garlic on cholesterol. Cholesterol levels are improved with garlic because of the mechanics of cholesterol synthesis is inhibited by the chemical allyl mercaptan.

According to Xu and Simon in their study: “Allyl mercaptan, a major metabolite of garlic compounds, reduces cellular cholesterol synthesis and its secretion in Hep-G2 cells.”

“The cytotoxicity, cellular cholesterol synthesis, and secretion of allyl mercaptan, a major metabolite of garlic compounds, were studied in Hep-G2 cells. . . The concentration of allyl mercaptan required to suppress cholesterol synthesis by 50% was approximately 25 microg/mL. Allyl mercaptan treatment of cells incubated with 1 mM of oleic acid also resulted in a significant decrease in the cholesterol synthesis compared with the cells incubated with oleic acid alone. . . The present study demonstrates that allyl mercaptan is effective in inhibiting cholesterol synthesis at concentrations as low as 5 microg, and its inhibition is concentration dependent.”[1]

And if that went a little over your head, basically this chemical gets in and stops the process of creating LDL which is the “bad” cholesterol your body produces when you don’t eat right. It improves the type of cholesterol in your system (it produces more HDL than LDL) and helps create a solid foundation to beat away any potential build up later on.

Does it Actually Help Diabetes?

One of the best and worst rumors about garlic is that it is great for dealing with diabetes. This has caused the medical world a bit of grief because many diabetic patients are turning to garlic supplements as their sole treatment rather than sticking to prescribed medications.

A study conducted in 2001 showed that alternative medication proved to be as expensive as regular prescription medication and reported lower levels of improvement.[4]

From this conclusion experts have recommended it as an addition to daily medication or food supplementation without using it as a sole form of treatment.

The science shows that it can be effective in lessening the effects of Type II Diabetes [5] because of the way it interacts with blood glucose, it is a hypoglycemic compound which naturally lowers blood sugar and helps reduce the side effects of high blood sugar.

Martha Thomson, Zainab M. Al-Amin, Khaled K. Al-Qattan, Lemia H. Shaban and Muslim Ali wrote in their study, “Anti-diabetic and hypolipidaemic properties of garlic (Allium sativum) in streptozotocin-induced diabetic rats,”:

“In this study the hypoglycaemic, hypocholesterolaemic and hypotriglyceridaemic effects of garlic were studied in streptozotocin (STZ)-induced diabetic rats. Daily treatment of STZ-induced diabetic rats with an extract of raw garlic (500mg/kg intraperitoneally) for seven weeks significantly lowered serum glucose, cholesterol and triglyceride levels. These results indicate that raw garlic possesses a beneficial potential in reversing proteinuria in addition to reducing blood sugar, cholesterol and triglycerides in diabetic rats. Therefore, garlic could be of great value in managing the effects and complications of diabetes in affected individuals.” See the #1 Garlic Supplement now

While this study was done on rats, the implications are similar and mean a lot to the world of diabetes. Working through the benefits of garlic can improve the way the medical world goes about prescribing diabetic medications. But for now it should be treated as a new ingredient in your overall health scheme.

Can It Cure the Common Cold?

It is most commonly known for its smell and flavor, but has been used for thousands of years as a cure-all for a medley of ailments depending on the culture. The common cold is one of the leading reasons for people to include more garlic in their diet. Using garlic for this ailment is actually pretty smart. See the #1 Garlic Supplement now

In 2011 a study was conducted which looked at the usage of garlic as a supplement to improve the immune system, their results followed a 45 day study where the subjects reported on the sick days felt in that span and the severity of them. Subjects who had been supplementing with garlic noted less severe symptoms, less actual sick days, and quicker recovery time. [3]

This also helped them reduce the chance of infection caused by the lessening of immune system that follows overworking your body. It is essential for augmenting the immune system, which helps prevent infectious diseases such as the flu or the common cold.

Does it Really Help Improve Sports Performance?

Garlic was used in ancient Egyptian times as a way to keep labourers going even after being overworked, the sulphuric chemicals in it is essential for building endurance and decreasing recovery time.

In a study done in 2006 experts: Morihara, Ushijima, Kashimoto, Sumioka, Nishihama, Hayama, Takeda wrote in their study “Aged Garlic Extract Ameliorates Physical Fatigue.”

“Aged garlic extract (AGE) has recently received attention as a potent anti-fatigue agent. The principal aim of this study was to elucidate the mechanism responsible for the ameliorating effect of AGE on physical fatigue in rats caused by repeated endurance exercise on a mechanical treadmill apparatus. Rats were subjected to endurance exercise 5 times per week for 4 weeks. . . These results indicate that AGE may facilitate the turnover of aerobic glucose metabolism, attenuate oxidative stress, and promote oxygen supply based on vasodilation, suggesting that AGE ameliorates the various impairments associated with physical fatigue.”[2]

For this reason athletes throughout the centuries have maintained a boisterous regimen of garlic supplements and recipes. But, if you’re not into the garlic smell there’s some great garlic extract supplements out there. See the #1 Garlic Supplement now.

Will it Ward Off Vampires?

Thanks to mysticism throughout the middle ages, and even before, garlic was considered a way to ward off vampires and other forms of evil spirits. No on is quite sure exactly where it started, but because it had been around for so long rumors of it being used for a variety of magical purpose have been perpetuated.

But contrary to popular belief, vampires may actually be attracted by garlic. In a study done by Norwegian researchers Sandvik and Baerheim in 1994 [6] , garlic can invite vampire bats and it may be reasonable cause to restrict the purchasing of garlic to maintain animal safety on Northern European farms.

Is Eating Garlic on a Date a Bad Idea?

Getting that delicious garlic chicken breast and asparagus may be the best decision you make the entire night (at least if you are a guy). For way too many years the common consensus was that garlic was a no-go on any date for fear of repelling your partner with bad breath. But more and more science is recommending a dense diet of garlic to improve your sex and love life.

Garlic is an aphrodisiac, especially for men. It relaxes the blood cells through your body and can also help clear up arteries and provide more elasticity to arteries and veins. Which means that getting it up will be a helluva lot easier, even when you’re nervous. See the #1 Garlic Supplement now

Vasorelaxation is essential for the improvement of blood flow, because it is literally a relaxation of your blood cells. And garlic is the exact thing to do this for you thanks to the chemical hydrogen sulfide.[7] Vasorelaxation is necessary for maintaining strength and preventing stroke. And, thanks to some pretty great anatomy garlic is built to improve vasorelaxation and let your blood flow where it needs to keep your body functioning properly.

And if your date still isn’t into that garlic-y smell, garlic softgels are an excellent source for all the same vitamins and minerals (without the taste or smell).

So How Often Should I Be Eating This To Get All These Benefits?

Garlic can have pretty bad side effects if you eat too much too often, it is recommended for a normal person to not eat more than 4 cloves (about a gram each) per day. For the nutricost garlic softgels we recommend eating 1 softgel 1-4 times per day, and this is the general recommendation. Before starting any supplement you should read the dosage in each capsule and adjust accordingly, and obviously ask your doctor first if you are diabetic or have a heart condition.
