Feeling rundown, on the verge of a cold, or simply keen to fortify your immune system against infection and viruses?
In the time of COVID-19 1, this is more understandable than ever.
You need an immune-boosting supplement to team up with your healthy diet, exercise, and sleep plan.
There are so many immunity-boosters on the market, it’s hard to find the best ones.
We’ve singled out Immune Defence, a vitamin-C and Zinc lozenge by Swiss Research Labs Ltd.
Our Immune Defence review covers the ingredients and how they work, possible side effects, pros, cons, customer experiences, and a final verdict.
Is Immune Defence your secret weapon during flu season, or is it simply a costly lozenge?
Time to find out.
What Is Immune Defence?
Immune Defence is a dietary supplement made by Swiss Research Labs Ltd. interestingly, it comes in lozenge form instead of the more common capsules or chewables associated with multivitamins.
Immune Defence is based around two key ingredients: Vitamin C and Zinc 2, two of the most common and well-researched immunity-boosting supplements.
It also contains smaller amounts of vitamin E and A thanks to Rosehip Powder.
About Swiss Research Labs Ltd.
UK-based company Swiss Research Labs Ltd. has been around since 1999, with brands such as Zotrim (weight loss) and Di.et.
They claim that their brands and products are “clinically proven” with “proven results”, with a few research resources available on their website.
However, it’s difficult to find information or reviews on Swiss Research Labs Ltd. outside of the website.
Immune Defence Ingredients
The Immune Defence ingredients list is refreshingly short and concise, with two sources of vitamin C.
However, it also contains sugar, a black mark on an otherwise great list.
- Zinc (3.5mg) as zinc Gluconate.
- Acerola powder (vitamin C).
- Rosehip powder 3 (vitamin C, E, and A).
- Oil of aniseed 4 (for flavor).
- Sugar (for flavor).
Vitamin C content: 2.5mg per lozenge which is rather low, so you may want to boost it with a chewable Vitamin C supplement if you want extra “C-support”.
How Does Immune Defence Work?
Instead of knocking back a capsule with water, you suck the Immune Defence lozenges until dissolved.
This means that the ingredients coat your throat and tongue before entering your system.
- Vitamin C and Zinc coat the throat, helping to fight viruses and bacteria causing pain and inflammation.
- Vitamin C is a strong antioxidant that fights free radicals that threaten immune cells.
- Vitamin C increases the number of important cells (lymphocytes and phagocytes) that keep the immune system working at full force.
- Zinc (which isn’t stored in the body so we need to get it through external sources) boosts the production and activity of immune cells, helping to fight an onslaught of viruses and/or bacterial infection.
- Zinc stops the body from becoming excessively inflamed 5 during illness or infection (chronic or excessive inflammation can lead to illness).
- As a bonus, zinc is also excellent for treating acne and keeping the skin healthy and clear.
A fair question, considering the current events.
However, no supplement will prevent Coronavirus, unfortunately.
Sure, a strong immune system may help your body to fight the virus and improve your recovery, but it will not prevent you from becoming infected outright.
Think of it this way: If you are physically weak and you enter a boxing ring against a fit component, you’re going to lose far more quickly than if you entered the ring fit and strong.
The immune system is similar: a healthy and strong immune system will fight infection faster and more thoroughly than a weak and struggling one.
To reduce your chances of getting Coronavirus, wash your hands thoroughly and often, follow your Government’s isolation rules, and practice social distancing as much as you can.
Immune Defence Benefits
- Easy to take (lozenge form, no water needed).
- Lozenge formula soothes sore, dry throats.
- Simple ingredients with low risk of side-effects.
- May help to treat acne or skin breakouts.
- Worldwide shipping.
How To Use Immune Defence?
It’s recommended that you take 1 lozenge every 2 hours, but no more than 4 lozenges a day.
The company suggests that you take Immune Defence when you feel a cold or sore throat developing.
You can also take them as a preventative measure to help fortify the immune system when you’re healthy.
Immune Defence Side Effects
Immune Defence only contains zinc and vitamin C, so it is very unlikely to cause side-effects when taken according to the directions.
However, excessive intake of zinc can impair copper absorption in the body.
This can cause:
- A weak immune system (ironically).
- Cognitive difficulties and poor memory.
- Vision issues.
Excess vitamin C consumption, while generally not harmful, may cause side-effects such as:
- Stomach cramps.
The company also states that if you are taking antibiotics such as Tetracyclines, you should avoid taking Immune Defence.
This is because zinc can interfere with these kinds of medications, reducing their effectiveness.
Is Immune Defence FDA-Approved?
No, the FDA does not approve dietary supplements and multivitamins.
Is Immune Defence A Scam?
No, it’s definitely not a scam.
The ingredients list is transparent, simple, and backed by substantial research, (unlike many other supplement ingredients).
You can feel safe when buying Immune Defence (however, be sure that you’re clear on the interesting return policy as discussed further below).
Is Swiss Research Labs Inc. Involved in Lawsuits?
We didn’t find any “dirt” on Swiss Labs Limited or Immune Defence, and they appear to be a trustworthy brand.
Immune Defence Reviews & Complaints
Unfortunately, we couldn’t locate any customer reviews to let us in on how real people have found this seemingly-great immune booster.
For this reason, we’ve got to base our final verdict purely on the ingredients.
We noticed that the Immune Defence Facebook and Instagram pages were only created very recently, since the COVID-19 outbreak, but there are no customer reviews posted there yet.
Immune Defence: Packages, Prices & Where To Buy It
Money Back Guarantee
Immune Defence offers a 100-day money-back guarantee.
However, this only applies to unused, unopened bottles of product.
Considering you have to try the product to know whether or not you’re happy with it, this is a little redundant.
Even more disappointing is that the refund policy only applies if you ordered more than one bottle/one month’s supply.

Immune Defence Pros & Cons
Immune Defence Review: Final Verdict
Despite the lack of customer reviews, we think Immune Defence is worth a try if you need to boost your zinc intake.
If you’re feeling a sore throat or cold coming along, it’s a good idea to suck on Immune Defence lozenges to fight the bugs and potentially speed up the recovery time.
If you’re looking for Vitamin-C especially, we recommend going for a stronger supplement such as liposomal Vitamin-C sachets.
Immune Defence doesn’t pack a big punch when it comes to Vitamin-C dosage.
Remember that excess zinc can impair copper intake causing all kinds of issues, so be sure to follow the dosage rules.
And if you’re taking antibiotics, pop the Immune Defence down for the duration of the course.
As always, check with your medical professional before taking a new supplement, to ensure it’s compatible with your medical history and current medications.
