Do you feel like you’re always getting sick? Are you constantly battling colds and the flu? If so, you may need to boost your immunity. Luckily, there are a number of natural treatments that can help. In this blog post, we will discuss some of the best ways to improve your immune system naturally.
Vitamin D is essential for a strong immune system. It helps the body to produce antibodies, which fight infection. Vitamin D can be found in fatty fish, eggs, and fortified milk. You can also get Vitamin D from exposure to sunlight.
Trouble keeping up with vitamin D supplements and worried about sun exposure? Not to worry, at my clinic we offer the option of a vitamin D injection. Under professional supervision, this is a safe and effective way to boost vitamin D levels quickly.
Another important nutrient for immunity is Vitamin C. Vitamin C helps the body to create white blood cells, which fight infection. Vitamin C can be found in citrus fruits, tomatoes, bell peppers, and broccoli.
Intravenous vitamin C is a great way to get a high dose of Vitamin C. By bypassing digestion, IV vitamin C can boost levels quickly. Intravenous vitamin C can also increase blood concentrations at levels that directly kill pathogens and inhibit cancer growth.
Zinc is another important mineral for immunity. It helps the body to create new cells and enzymes that fight infection. Zinc can be found in oysters, beef, pork, chicken, and beans.
Zinc can also be added to intravenous infusions for an added immune system boost.
If you’re looking for a kid friendly and great tasting way to boost your immunity, elderberry syrup is a great option. Elderberries are rich in Vitamin C, Vitamin A, and antioxidants. They have been shown to reduce inflammation and fight infection. You can find elderberry syrup at most health food stores.
Ginger is another great option for boosting your immunity. Ginger is a natural anti-inflammatory and can help to reduce congestion. It can also help to soothe a sore throat. You can find ginger in the form of capsules, tea, or syrup.
Garlic is another excellent food for boosting your immunity. Garlic is rich in Vitamin C, sulfur, and antioxidants. It has been shown to fight infection and reduce inflammation. You can add garlic to your food or take it in supplement form.
Selenium is a trace mineral that is important for immunity. Selenium helps the body to produce antibodies, which fight infection. It can be found in Brazil nuts, tuna, shrimp, and eggs.
Selenium can also be added to an intravenous infusion for an added immune boost.
Vitamin A is an important nutrient for immunity. Vitamin A helps the body to produce white blood cells, which fight infection. Vitamin A can be found in sweet potatoes, carrots, dark leafy greens, and squash.
Probiotics are live bacteria that are good for your gut health. Probiotics help to keep the balance of good and bad bacteria in your gut. This can help to improve digestion and boost immunity. You can find probiotics in yogurt, kimchi, sauerkraut, and kombucha.Probiotic supplements are also available.
There you have it! These are just a few of the best ways to boost your immunity naturally. By including these foods and supplements in your diet, you can help to keep yourself healthy and avoid getting sick. In individuals requiring an extra boost, injection and intravenous treatments are available and effective. Do you have any other favourite natural immunity boosters?

Probiotics help boost the immune system – Studies have shown that probiotics affect immune cells throughout the body. When certain strains of probiotics are introduced into our intestine they help to repair intestinal cells and they boost production of antimicrobial substances. In one study, 326 children aged 3-5 years were randomly assigned to receive, in double-blind fashion, probiotic supplementation. Treatments were given twice per day in divided doses for 6 months, including the winter season. Compared with placebo, the probiotic group had the following results; fever reduction 53-73%, cough reduction 41-62%, decreased runny nose 28-59%, decreased need for antibiotics 68-82%, reduced absence from school 28-32%.
Elderberry extracts inhibit bacteria and viruses – Not only does elderberry syrup taste great, studies have shown that it inhibits the bacteria and viruses associated with common colds and the flu. One study demonstrated that an elderberry liquid extract possesses antimicrobial activity against both streptococci bacteria and influenza viruses. Another study looked at 312 air travellers flying from Australia to an overseas destination. Those travellers who took an elderberry extract before, during and after travel had fewer colds, less sick days and less symptoms.
Vitamin C supports immune cells – Vitamin C is very important for optimal immune system functioning. Vitamin C helps immune cells get to where they need to be, kill pathogens effectively, protect the body from damage and clean up after battling infections. Studies have shown that adequate vitamin C in the blood helps prevent infections, is necessary to fight infections and helps with recovery. The recommended daily intake of vitamin C is 100-200mg/day; however during active infection, the metabolic demand increases and therefore the requirement for vitamin C is likely to be higher. Even in this day and age, vitamin C is the fourth leading nutrient deficiency in North America. Poor diet and increases in free radical exposure due to an unhealthy lifestyle may be contributing factors. Excellent sources of vitamin C are Broccoli, Citrus Fruits and Berries.
Zinc is essential for immune system communication – The importance of zinc for proper immune function has been well established. Zinc deficiency undoubtedly causes immune system malfunction. The cells of our body are in constant communication. During infection there is a need for effective communication between immune cells in order to get rid of the “bad guys”. Communication happens in the form of chemical messengers and enzymes. Zinc is an essential component of these chemicals and enzymes. As with vitamin C, during active infection our requirement for zinc is likely to increase. Studies have shown that Zinc supplementation during infection can shorten the duration of the illness. Excellent dietary sources of zinc include: Meat, Shellfish, Legumes, Nuts and Seeds. Supplementation may be important with a vegan or vegetarian diet.
Vitamin D is the supervisor of the immune system –Vitamin D has many functions in the body, and receptors for vitamin D can be found on many different tissues. One important function for vitamin D is in the modulation of our immune system. Studies have suggested that vitamin D is able to both calm down and rev-up the immune system according to what our body needs it to do. This is why Vitamin D is thought to be as important in autoimmune disorders as it is in infections.
Vitamin D deficiency can cause the immune system to behave erratically. Unfortunately in Canada we have one of the highest incidences of vitamin D deficiency in the world. Our primary source of vitamin D is from sunlight and therefore supplementation becomes important especially during the winter months. Studies have shown that there is a higher incidence of upper respiratory tract infections in athletes who are deficient in the vitamin and who train in the wintertime. Supplementation had preventative and symptom reducing effects. Aside from sunlight, some dietary sources of vitamin D are: fortified foods, fatty fish, beef liver, egg yolks and cheese.
