Watermelon & Mint smoothie

10 drinks to fight colds & support immunity

08 Nov 2021 • 6 min read


If your immune system is functioning normally, the less chance you’ll have of falling ill and the quicker you’ll recover if you do. 

To make sure your immune system is in tip-top condition, it pays to think about what you’re putting into your body.

There are a number of foods that you should try to introduce to your diet to support your immune system, but if you don’t fancy chewing on raw broccoli or garlic, you could try one of our fancy immunity drinks.

As well as being super tasty, a healthy immunity drink can be even easier for your body to digest and absorb because they’re in fluid form.

That’s why we’ve put together 10 tasty beverages that can help you get the nutrients your body needs to help support your immune system.

Why immune booster drinks don’t ‘technically’ exist 

The reality is, there is no food or supplement that will ‘boost’ your immune system.

Evidently there are foods that impact your health, as you’ve hopefully learned – vitamins and minerals pay an important keeping your immune system running in the way it should.

But ‘immunity-boosting’ supplements or immune boost juices are a bit of a myth.

By eating a healthy, balanced diet which includes fruit and vegetables – including fresh, frozen and tinned which are all equally as good.

So, it’s more of a case of looking after yourself and giving your body what it needs.

Simply put, of course you’re inclined to have the odd takeaway or fast food, but this should be on occasion rather than something you do as part of your diet.

Instead, look to add fresh fruit and vegetables where you can. By providing it with the nutrients it needs your body and more importantly, your immune system will thank you.

10 drinks that support your immune system

These 10 drinks can help you support your immune system and protect it from colds.

We’ve included ones you can make yourself and some ready-made products.

1. Hot lemon and ginger tea

Lemon and ginger are both full of antioxidants and vitamins, so drinking a cup every day can be good for your immune system.

Ginger can also help increase blood circulation and lemons can help soothe inflammation.

For extra support, you could sprinkle some cinnamon on top - this slows down bacteria in your system, stopping it from multiplying so quickly.


Serves: 2

How to make hot lemon & ginger tea


Boil a kettle


Cut the lemon in half, slicing one half and squeezing the juice from the other.


Divide the lemon slices and juice between 2 mugs (or a tea pot with a filter) and add the sliced ginger.


Pour boiling water into the mugs and leave to brew for a few minutes or until it’s cool enough to sip.


Sweeten with honey if you wish.

For extra support, you could sprinkle some cinnamon on top - this slows down bacteria in your system, stopping it from multiplying so quickly.

2. Watermelon and mint smoothie

If you love smoothies, why not have a go at making your own using a few slices of watermelon and some mint?

Watermelon is an immune-supporting food as it contains lycopene.

If your nose is bunged up, the mint will help you breathe more easily as it contains menthol.


Serves: 2 

  • 300g diced seedless watermelon
  • 4 tablespoons demerara sugar
  • 950ml sparkling water
  • 4 fresh mint leaves
  • Crushed ice

How to make a watermelon and mint smoothie


Add all the ingredients to a blender.


Blend ingredients together until you have your desired consistency and serve.

3. Berry smoothie

Berries are really good for you as they’re full of the vitamins your body needs.

You could combine strawberries with raspberries and blueberries or mix it up with some other types of fruit for an even more nutritious meal.


Serves: 1

  • 100ml plant-based milk
  • 25g gluten-free oats
  • 75g frozen berries
  • 1cm piece fresh ginger
  • 1 celery stalk
  • 1 tsp agave or maple syrup

How to make a berry smoothie


Use the back of a metal spoon to remove the skin from the ginger before finely grating it


Add the oats to a blender and blitz until powdered, then add the celery and frozen berries and blend


Add the remaining ingredients and blend once more until smooth - scraping down the sides of the blender to ensure everything is thoroughly combined


Pour into a glass and garnish with a stick of celery if you're feeling fancy - enjoy with a reusable straw!

4. Orange or grapefruit juice

A glass of your favourite citrus juice every morning with your breakfast will give your body some much-needed vitamin C.

You could make your own juice or buy it ready-made, the decision is yours.

If you don’t like citrus fruits, a glass of tomato juice is a good alternative as tomatoes are rich in vitamin C too.

5. Green juice

Is there anything healthier looking than a green juice? It’s probably because they are! Green juices are packed with vitamins, minerals and fibre, which can help support your immune system.

Liabrighton – Impressive strength

Very high strength vitamins and vegan too very sour but I like that would imagine it’s the vitamin C paired with the tart elderberry flavours.
