Immune Support Supplements

Sick of getting sick? An immune support supplement could be just what you need! Here at Holland & Barrett, we stock a range of remedies to help support and strengthen your immune system, including vitamins, minerals and products to help support your natural immunity like Echinacea.

What is immunity? Immunity is the ability of an organism to resist a toxin or infection.

In humans, the immune system acts as the body’s defence against infections – attacking germs and foreign substances and banishing them from the body. The strength of our immune system is determined by multiple factors, like our genetic makeup, lifestyles, diet and the environments we have been exposed to over the years.

How to support your immune system:

Now, there’s not much we can do about our genes, but one thing we can do is control our diet. There are certain vitamins and minerals that help the immune system function normally, so making sure we keep them topped up is key. Nature also provides natural remedies to help boost immunity, read more about them below.

Vitamin C for immunity: there’s a reason your doctor tells you to make sure you’re getting enough vitamin C in the winter – it’s essential for the normal running of your immune system. If you’re worried that you’re not getting enough naturally day-to-day, why not try taking a vitamin C supplement?

Vitamin D for immunity: the elusive vitamin D is key for normal immune function but is notoriously hard to get in countries like the UK, unless you’re constantly sunning it up on holiday that is! This is because our bodies need sunlight to make vitamin D naturally, and it’s not very prevalent in most people’s diets. Don’t worry though, a vitamin D supplement could sort you out!

Zinc for immunity: the body needs zinc for a variety of important tasks, one of them being supporting the immune system to help your body stave off infections. Keep your zinc levels up easily with zinc supplements.

Manuka honey: Manuka honey is a special high-quality honey made in the wild pastures of New Zealand. It contains naturally powerful antibacterial properties and Manuka honey can do wonders for a sore throat when you mix it with warm water!

Echinacea can help fight common colds and the flu: for hundreds of years, people have been taking echinacea for colds to help relieve the symptoms and duration of cold and flu illnesses. Echinacea has been used traditionally to relieve the symptoms of common cold and influenza-type infections.

    Vitamins for the immune system at Holland & Barrett come in a variety of different forms from tablets to spray with many items suitable for vegans. A variety of our vitamins provide immunity support - especially during the winter months - and a range of other different benefits from the maintenance of healthy teeth and bones to the support of normal collagen formation.


    Vitamin D3 is also known as the sunshine vitamin, as we get it from exposure to the sun.


    It helps to support the absorption of calcium and phosphorus, which in turn helps to keep bones strong. Vitamin D3 also helps to support the normal functioning of the immune system.

    There are a few food sources of vitamin D3, including fish such as salmon and mackerel as well as egg yolks. But we often do not eat enough of these to get the amounts of Vitamin D3 we really need.


    We also get vitamin D3 from exposure to the sun. But it can be difficult to get sufficient exposure during the winter months or if you spend a lot of time working inside.


    Therefore it is recommended that you should take a daily vitamin D3 supplement.


    You should take one Holland & Barrett Vitamin D3 Tablet daily, preferably with a meal.

    Fruits and vegetables can help to support the normal functioning of the immune system, thanks to their vitamin content.


    Citrus fruits such as grapefruits and oranges are high in vitamin C, and broccoli is packed full of vitamins and minerals, as well as containing vitamins A, C and E, fibre and antioxidants.

    Vitamin C has a number of important functions in the body. It helps to maintain normal skin, blood vessels, bones and cartilage.

    You can take a vitamin C dietary supplement to help top up your vitamin C levels.


    You can take one to four Holland & Barrett Chewable Vitamin C with Rose Hips Tablets each day, preferably with meals.


    These have a yummy orange flavour and you can opt to chew them, so they are perfect for anyone who does not like swallowing tablets whole.

    Zinc is a nutrient which is found in cells throughout the body.


    It helps to support the normal functioning of the immune system, as well as supporting the production of proteins and DNA.


    Holland & Barrett High Strength Zinc Tablets is a high strength, daily zinc supplement, which is a great way to boost the overall levels of zinc in your body.

    Red meat and poultry are some of the best sources of zinc.


    Vegan sources of zinc include beans, nuts, whole grains and fortified breakfast cereals.


    If your diet is low in zinc, you can also take a dietary supplement.
