The best vitamins to boost your immune system
Boosting our immune systems has never been more important, these vitamins can help.
In the current climate, it’s absolutely understandable to have your immune system on your mind. Taking care of your natural defences has never been more important.
Natural ways to boost your immune system
There are plenty of natural ways to boost your immune system. Getting enough high-quality sleep, exercising regularly, managing your stress levels, and making sure you’re well-hydrated are all really important for immune function.
But, if you feel like you need an extra boost, there are several vitamins that are good for your immune system. So try to make sure you are getting enough of these either through the foods you eat or by taking a supplement.
What specific vitamins are good for immune systems?
Some of the most commonly recommended vitamins for the immune system are vitamin C, vitamin D, and zinc.
We’ve broken it down below to help you understand how they work with your immune system, as well as how they impact your brain. After all, what’s good for the brain is good for the body.
Does vitamin C boost the immune system?
Probably the one you’re most familiar with—thanks to your nana force-feeding you oranges as a kid—vitamin C is good for the immune system. It helps to reduce inflammation, strengthens skin barriers, and encourages the production and function of white blood cells.
It’s been found that vitamin C may prevent colds for acutely stressed people, (that’s most of the world at the moment then). And, it’s useful in reducing the duration of a cold and may help to lessen the severity of symptoms.
Brainy bonus: Higher levels of vitamin C are directly associated with higher levels of cognitive function.
Food sources: blackcurrants, kiwi, green and red peppers, oranges.
Vitamin D and the immune system
Vitamin D3 has been a hot topic since Public Health England started recommending it as a daily supplement in May 2020. While it’s true that we can get it from sunlight, there’s little to no chance of us getting exposure between 10am and 3pm to produce enough of it—especially with the vast majority of people working from home.
Many studies have shown that vitamin D3 is essential for the proper functioning of the immune system, as it enhances the function of immune cells that actively protect your body from pathogens.
Known to act in the first stage of the body’s immune response, supplementing with D3 has been shown to correlate with a stronger immune system, it is a great immune booster.
Brainy bonus: It’s thought that vitamin D3 reduces harmful amyloid plaques in the brain (high levels of amyloid plaque is associated with Alzheimer’s disease).
Food sources: eggs, fortified margarine.
How much is in the Smart Supplement: 20mcg, 400% of the NRV. This is definitely more than enough, plus you don’t have to take a pill full of nasty caking agents and fillers (yuck!).
Is zinc good for your immune system?
Although zinc is a trace mineral—meaning you only need very small amounts—it plays a big role in caring for your immune system.
Not getting enough of it will result in your immune cells not being able to protect your body from bacteria properly. Zinc deficiency has been linked to a decrease in immunity and higher risks of infectious diseases in the respiratory tract.
Supplementing with zinc has also been shown to improve the duration and severity of cold symptoms.
Brainy bonus: Zinc is known to be helpful for spatial memory - e.g. your recollection of the environment around you. It also helps with normal brain function and can help with symptoms of depression and low mood.
Food sources: pumpkin seeds, shellfish, legumes.
How much is in the Smart Supplement: 5mg, 50% of the NRV. We do this on purpose as most people get some zinc from the diets easily and only need a top-up.
