Garlic Supplement for Preventing the Common Cold: Will it Work?

Garlic Supplement for Preventing the Common Cold

Common cold and cough have become extremely common these days. Who hasn’t had a cold and cough this winter? There’s hardly any person, right?

The common cold is equally common as the word ‘common’. Although it has been an extremely common illness, there aren’t any medical ways to prevent it.

Research explains how taking natural supplements or consuming healthy foods and improving immunity can prevent common cold and cough naturally.

However, it depends on which supplement or herb suits you the best. Of all cold supplements, Garlic Supplement is extremely common and healthy as it is normally tolerated by everyone.

What is a Garlic Supplement?

It is the age of organic supplementation for our health. As our foods have become ‘fast’ and ‘junk’, we often need natural ingredients, herbs, spices and unique fruits and vegetables to restore our health.

As garlic’s strong flavour may not be loved by all, science has put it in the form of a capsule so you get the benefits without any side-effects. We’re talking about such organic, pure and chemical-free garlic supplements.

Whom are Garlic Supplements for?

We could answer ‘whom’ as well as ‘what’ here. Garlic supplements are for everyone but tiny kids. You should feed as many fruits and vegetables to your kids as possible.

Most garlic supplements do not require a doctor’s prescription but we don’t advise you to feed your children any garlic supplements. Otherwise, they’re safe for everyone. 

Garlic Supplementation is usually for cold, cough, low immunity, cholesterol, blood pressure and cardiovascular problems. Since it has many great properties, garlic works miraculously for cold and cough.

How do Garlic Supplements work for common colds?

A normal garlic supplement dosage for common cold and flu should be 600 to 1200 mg a day. If you decide to eat raw garlic, you can have two cloves of garlic twice or thrice a day. Most garlic supplements have to be taken with a glass of water with or without meals.

Which form of Garlic Supplements should you take?

Garlic Supplements usually come in the form of soft gels or capsules. However, you may also find some powder supplements that have dried garlic powder in them or some herbal tonics may contain garlic as well.

Since most people do not love the strong smell and taste that lingers in your mouth after eating it, they prefer soft gels or capsules.

Which properties of Garlic benefit the common cold?

Garlic contains many beneficial properties:

  • Acts as a Multivitamin: Garlic acts as a multivitamin as it has manganese, selenium, vitamin C, vitamin B6, and antioxidants such as allicin.
  • Antiseptic: It slows down the growth of bad microorganisms in your gut that bring your immunity levels down.


  • Antibacterial: Garlic helps kill bacteria that can be very harmful during the common cold. It promotes the growth of good bacteria so your body can naturally fight the common cold.


  • Antifungal: It prevents fungal infections that can weaken your immunity and make symptoms of cold and flu severe.
  • Antiviral: Garlic fights viruses very effectively. It prevents viral infections and protects your respiratory organs well. It even keeps you warm during the common cold.

Do Garlic Supplements have any side-effects?

No, most garlic supplements are safe for consumption. However, as mentioned above, you can check with your doctor if you plan on giving the supplements to your children.

Excessive garlic supplementation can have reverse effects in some cases so always check with your doctor or follow the dosage instructions.

Consume the supplements for a limited duration only. Prolonged reliability of any herb or medication can have side-effects. WebMD explains that excessive consumption can even cause diarrhoea, asthma, stomach problems or liver issues in rare cases.

Are there any studies that suggest how Garlic Supplements can cure colds?

PubMed explains, “Supplementation with aged garlic extract improves both NK and γδ-T cell function and reduces the severity of cold and flu symptoms.

These results suggest that supplementation of the diet with aged garlic extract may enhance immune cell function and that this may be responsible, in part, for reduced severity of colds and flu.”

Hence, we can say that Garlic supplements may not be the panacea to the common cold but can certainly reduce the number of times you have to suffer from cold and flu, also its severity.
