Immune Defence Zinc Lozenges Review – Is it Worth Buying?

Immune deficiency is something that affects a huge majority of us. We are all born with a good working immune system but over time it can become weakened or compromised. Immune Defence aims to address this problem.

What is Immune Defence?

Immune Defence is a health and wellness supplement produced in the UK by Swiss Research Labs.

Despite the name, the company is not Swiss. It’s a British supplement manufacturer from Nottingham.

As the name suggests Immune Defence is a supplement aimed at people who wish to boost their immune system.

This type of product tends to be popular with two kinds of people: people who are unwell and want to recover faster and people who wish to avoid becoming ill in the first place.

Although most health and wellness supplements are pills, Immune Defence is not. It’s an aniseed-flavored lozenge.

The lozenges contain several nutrients that have a scientifically-proven connection with the immune system.

The main ingredient is zinc.

If you are already familiar with zinc-providing products of this nature you may have noticed they are often in lozenge form.

There is a reason why this is so.

If you are taking zinc to boost your immune system and prevent disease, a vitamin pill may be fine.

However, if you are using it to fight a cold or other existing infection, lozenges work better.

Because they dissolve slowly in the mouth, lozenges give zinc the chance to be absorbed locally instead of down in the stomach.

This can help get the mineral to infected tissues in the nose.

It’s not surprising if you think about it. When zinc enters the blood via the thin membranes in the mouth, traveling via the blood vessels, the nasal passage is only a short trip away.

The other immune system-boosting nutrients are vitamins A, C, and E. These are known as the “ACE” vitamins. 

This powerful trio is often sold together because research shows they are more effective when taken in unison than they are if you take them individually.

Immune Defence Benefits

Swiss Research Labs make six main promises.

The first five refer to the immune system benefits the ingredients provide. The sixth one is to do with convenience of use.

  • Proven Immune support
  • Antiviral defense during cold and flu season
  • Reduces the duration of cold symptoms
  • Care for your immune system during times of stress
  • Immune support for the whole family
  • Easy to use immune support on the go

How Does tImmune Defence Work?

Immune Defence helps people to attain/regain good health by providing the immune system with several nutrients.

Scientific study shows all four of the nutrients help the immune system to fight disease.

The human immune system is more complicated than most people realize.

Although the fact that white blood cells fight infection is pretty much common knowledge, white blood cells are only a small cog in a much bigger machine.

The human immune system also relies on the specialist activity of T Cells, B Cells, and many other biological devices.

Just as the metabolism needs B Vitamins to exact energy from food, the immune system (as a whole) needs specific nutrients to help it fight infection.

What’s the Best Way to Take Immune Defence?

The thing to remember is, despite the flavor and format, you are not dealing with candy.

You only take one lozenge at a time and need to separate the doses by at least two hours.

It’s permissible to take a maximum of four lozenges per day and it’s important to remember to suck them.

Chewing the lozenges and then swallowing them would reduce the benefits—especially during times of sickness.

Ingredient Profile and Value

Immune Defence could be seen as being a pretty simple formulation. It only contains three active ingredients:

  • Zinc gluconate
  • Rose hip Powder
  • Acerola powder

The formulation also contains some aniseed oil and sugar to provide the taste.

Zinc gluconate is the substance you are left with after you combine zinc with gluconic acid. It’s commonly used in supplements and medication that provide the body with zinc.

Rose hip and Acerola are berries. The two extracts are included here because they are natural sources of Vitamins A, C, and E.

Now let’s take a closer look at the nutrients Immune Defence provides and what they can do.


Zinc is a mineral your body cannot store.


You need to consume it every day. The RDA is 8 mg per day for women and 11 mg per day for men. It’s safe to take considerably more.

In fact, taking more may be beneficial when you are ill.

Each Immune Defence lozenge contains 3.8 mg of zinc so, if you take four per day it will give you 15.2 mg. That’s a respectable amount.

There’s plenty of research that supports using zinc as an immune system booster.

The results of several clinical trials suggest taking zinc can significantly reduce the duration of the common cold.

Other research shows zinc supplements may be particularly effective when you commence treatment within 24-hours of the first symptoms showing.

Zinc is not only effective against colds. Research shows it can help the body fight other viruses too.

When researchers in Thailand used Zinc to treat children suffering from acute respiratory tract infection, it helped them recover faster than the placebo group and they were able to go home sooner. (

Vitamin C

Vitamin C is an important vitamin you need to consume every day.

If you don’t eat enough fruits and vegetables you may not get enough of this important water-soluble vitamin.

vitamin C

That could be very bad for your immune system because it needs sufficient Vitamin C to function correctly.

One of the things Vitamin C does is help the body produce white blood cells.

The white cells are very important to immune function, they have the job of neutralizing bacteria, viruses, and other pathogens that invade the body and cause sickness.

Vitamin C is also a powerful antioxidant that further protects the body by purging the body of antioxidants that may endanger the health. (

Vitamin A

Often termed the “anti-inflammation vitamin”, Vitamin A is another vitamin you need to consume daily if you want to keep your immune system strong.

vitamin A

Research shows Vitamin A promotes a strong immune system, helps regulate it.

It also provides enhanced defence from multiple forms of infectious disease.

Researchers expect Vitamin A to become more commonly used as a therapeutic treatment after future studies reveal more about its capabilities. (

Vitamin E

Unlike vitamins C and A, Vitamin E is a fat-soluble vitamin.

That means your body can store it but you still need to make sure your diet provides an adequate amount of Vitamin E.

Vitamin E

Among other things, Vitamin E is a powerful antioxidant that helps protect your cells from damage that may weaken your immune response.

Study is still in its early days, but some research suggests supplementing with Vitamin E may retard the progression of HIV.  (

Are There Any Customer Reviews on Immune Defence?

Unfortunately, I was unable to find any Immune Defence customer reviews. That’s a little disappointing but at least nobody appears to have anything bad to say. That in itself can be taken as a good sign.

Is There a Risk of Side Effects?

Immune Defence provides a combination of nutrients that the immune system needs. The inclusion rates are adequate and are not overly high.

You don’t need to be unduly worried about side effects with a product like this. 

However, Swiss Research Labs warns against taking more than four lozenges per day. 

Doing so may have the potential to cause side effects such as lethargy, nausea, and copper deficiency.

As with any other health and wellness product you need to use Immune Defence lozenges with respect.

They are for boosting immune function and should not be treated like candy.

Although the amount of zinc the lozenges provide is within safe recommendations, Swiss Research Labs suggest women check with a doctor before using the product if they are pregnant or nursing a child.

Anyone who has ongoing medical conditions or would need to use the lozenges alongside medication would be wise to get prior approval from a doctor too.

Purchasing Options and Considerations for Immune Defence

You can only buy Immune Defence via the official website. Each bottle contains 120 lozenges.

That’s enough to last for 30 days if you are taking the maximum dose of four lozenges per day.

The RRP is USD 54.95 per bottle but don’t expect to pay that much. Swiss Research Labs normally offers a discount.

At the time of this review, it was possible to buy a bottle of Immune Defence for USD 44.95.

One of the good things about this product is the price you see is the price you pay.

There are no additional charges for shipping and orders are dispatched (worldwide) within 24-48 hours of being placed.

Customers who want to get more bang for the buck can opt to place larger orders in exchange for further discounts.

At the time of this review, the best deal went to people buying a 5-month supply of pills. The bulk-buy discount brought the price down to just USD 174.75. That’s USD 100 less than the RRP.

As far as the price goes, this product is not bad at all and you have to remember, unless you are using Immune Defence during periods of illness, you are unlikely to be using four lozenges per day.

During periods of good health, presuming an adequately nutritious diet, you probably won’t need to take any lozenges at all.

However, if you are aiming at boosting your immune system to prevent disease, you may want to take one of two capsules per day to make sure your levels of zinc and Vitamins A, C, and E remain sufficiently high.

If this is your aim, you could be boosting your immune system for a matter of cents per day.

What is the Guarantee?

Swiss Research Labs offers a 100-day refund policy (for unopened products) but no money-back guarantee.

The returns “guarantee” is only valid when customers place larger orders. If you only order a 30-day supply of pills and then wish to return it, you won’t be able to get a refund regardless of if you opened the bottle or not.

The lack of a real money-back guarantee is somewhat disappointing but it’s normal for health and wellness products of this nature.

Money-back guarantees are more common with diet pills and other supplements that aim to change the physique.

Immune Defence is a lozenge for people who want to boost their immune system by attaining a better balance of zinc and other important nutrients that are known to support the body’s ability to fight disease.

Science shows the nutrients in the lozenge are necessary for a strong immune response. All Swiss Research Labs is doing is providing a lozenge that contains the nutrients.

Unlike a diet pill that may fail to do the things the manufacturer says, Immune Defence does what it’s supposed to do right from the start—it provides a specific blend of nutrients involved in immune function.

In a circumstance like this, I think we can forgive the lack of a guarantee. 

Immune Defence Review Conclusion

Immune Defence is a health and wellness product that provides immunity-boosting nutrients in a convenient and accessible form.

It’s a good option for anyone wishing to ensure their immune system is operating at maximum capacity.

The lack of customer feedback is not ideal but there is plenty of scientific evidence that shows what the main ingredients can do.

If there is a problem with this product, it’s the lack of a second flavor option. Although many people love the taste of aniseed, there are bound to be a few potential users who do not.

Would anyone really avoid a product that can keep them well just because they don’t like the flavor? Hopefully not.

However, it would be fantastic if Swiss Research Labs were to offer one or more additional flavor options in the future.
