How to Boost Immune System with Juice

If you've got a cold or feel like one is coming on, there is nothing better than than a cold press juice to make you feel better! Nutrient-rich cold press juice can help boost immune system and assist your body to fight off that nasty cold or flu. In general it is important to look at improving our immunity as this minimizes the frequency that we get sick, how sick we are and the length of time we are sick for. There are lots of fruits and vegetables who are powered to assist with fighting off nasties and can help you overcome a sickness naturally. Boost immune system with the amazing properties of commonly found fruits and vegetables.


The concept of living juice was first introduced by Dr. Norman Walker who said “The human body is inextricably dependent on the quality of food and no less its compatibility with the needs of the body”. When your body is not at its best it is imperative to provide it with a maximum amount of particular foods that are crucial for optimum immune system functioning. When it comes to the immune system, two vitamins are essential for wellbeing: A and C.

Vitamin A

Essential for boosting immune function in winter. It has the same immune boosting properties as vitamin C, and can be found in a range of fruits and vegetables. Deficiency in vitamin A can lead to increased viral infections during winter. Juicing carrots, kale, rockmelon spinach and apricots can help protect you immune system from nasty flus and viruses.

Vitamin C

A champion when it comes to fighting winter colds and keeping your immune system strong. Unlike animals, humans cannot produce vitamin C, so rely on outside sources to get recommended doses. This vitamin is a white blood cell simulator and helps defend the body against viruses and bacteria. Research has shown that high doses of vitamin C can reduce the severity of symptoms during times of sickness. Drinking cold press juices rich in vitamin C is a great way to help keep the immune system strong this winter. Vitamin C can be found in fruits and vegetables such as Guavas, Kale, Kiwi Fruits, Oranges, Papaya, and Strawberries.

Why not just eat the fruit and vegetables?

Are you asking yourself “why not just eat whole vegetable and fruit instead of extracting the juice and discarding the fibres?” Dr. Norman Walker in his book Fresh Vegetable and Fruit Juices said “The answer is simple: solid food requires many hours of digestive activity before its nourishment is finally available to the cells and tissues of the body”. By drinking cold pressed juice, the juice is absorbed directly into our bloodstream providing the vital nutrients we all need when we aren't well. Also drinking juice is a lot easier - it would be quite difficult to consume such a massive intake of fruits and vegetables but drinking a glass of juice is easy.

Here are our favourite recipes to boost immune system and get you feeling 100% again in no time!

Green Juice

Spicy Green Juice

  • 8 large leaves kale
  • 2 giant handfuls spinach
  • 8 large leaves romaine lettuce
  • 8 stalks celery
  • 1 large cucumber
  • 2 small Granny Smith apples
  • 2 large lemons
  • 1 piece ginger
  • Salt and cayenne pepper to taste, about 1/4 tsp to 1/2 tsp each

Consuming more dark leafy green vegetables is properly the #1 thing you can do to improve your overall immunity and for that matter, your well being in general. However, in terms of immunity, green vegetables help to boost immune system, improve liver and kidney function and clear congestion especially in the lung by reducing mucus. Greens are very high in calcium, magnesium, iron, potassium, phosphorous and our favourite immunity helping vitamins C and A. You can change the recipe to suit what ever green vegetables you prefer - the more the merrier!

Cayenne pepper gives this juice a nice kick and is also rich in the chemical 'capsicum' which is a source of Vitamin C. The Vitamin C in cayenne pepper will cleanse your cells and tissues of toxins. The beta carotene and antioxidants in cayenne pepper help to build healthy mucus membrane defending against viruses and bacteria. Because cayenne pepper is spicy, it will also raise your body temperature and make you sweat, which helps to increase the activity of your immune system. Adding chill would have the same effect.

Ginger contains shagaols and gingerols which is what gives it that spicy kick. They also help to open your sinuses and stimulate blood circulation, which means more oxygen reaches the tissues to help fight infection and bacteria.


Orange Zinger

  • 3 large oranges
  • 1 large grapefruit
  • 2 kiwi fruits
  • 1 lemon
  • 3 carrots
  • 2 cloves of garlic (optional)
  • 1 peice of ginger

This is a citrus-packed punchy juice which will put a spring in your step! Oranges, grapefruit and especially kiwi fruit are packed full of Vitamin C (kiwi fruit more than any other)! Kiwi also contains Vitamin E which helps to protect the body from viral and bacterial infection.

Garlic, although optional, is the key feature of this juice and will help to boost immunity more than any other ingredient! Garlic has been used for thousands of years to help fight disease. Garlic contains allicin which fights infection and bacteria.

Garlic is so good for immunity that British researchers gave 146 people either a placebo or a garlic extract for 12 weeks; and they found that the garlic takers were two-thirds less likely to catch a cold! Dr. Norman Walker states "the ethals in garlic juice are so potent and penetrating that they can help to dissolve accumulations of mucus in the sinus cavities, in the bronchial tubes and in the lungs".
