31 Oct 4 Useful Nutrients to Help You Through the Cold & Flu Season
When the days get shorter and the temperature drops, so too can your immune defences. The cold and flu season often brings sniffles, sore throats and fatigue — but the right nutrients can help support your body’s natural resilience. Even if everyone around you seems to be catching something (especially kids bringing bugs home!), a strong immune system can help you fight off infections before they take hold.
Here are four key nutrients that can make a big difference during this time of year.
- Vitamin C – The Classic Immune Booster
Why you need it:
Vitamin C is one of the most well-known nutrients for immune health. It helps stimulate the production of white blood cells — your body’s frontline defence against infections. It’s also a powerful antioxidant, helping to protect your cells from damage caused by free radicals.
Food sources:
You’ll find vitamin C in citrus fruits (oranges, lemons, grapefruits), kiwis, strawberries, bell peppers and broccoli.
Supplement benefits:
While it’s ideal to get nutrients from food, vitamin C is water-soluble, meaning your body doesn’t store it. A daily supplement can help maintain consistent levels, especially if your diet is lacking or you’re under extra stress — both of which can deplete vitamin C.
- Vitamin D – The Sunshine Nutrient
Why you need it:
Vitamin D supports your immune system by helping regulate the body’s inflammatory response and enhancing the pathogen-fighting power of white blood cells. Low levels of vitamin D have been linked to increased susceptibility to colds and flu.
Food sources:
Natural sources include oily fish (like salmon, mackerel, and sardines), egg yolks, and fortified foods such as cereals and plant-based milks. However, most of our vitamin D is made in the skin through sunlight — which can be limited during autumn and winter.
Supplement benefits:
Because it’s difficult to get enough sunlight during the colder months, a vitamin D supplement is recommended for most people. It’s an easy and reliable way to keep your immune system functioning at its best.
- Zinc – The Infection Fighter
Why you need it:
Zinc is crucial for the normal development and function of immune cells. It helps shorten the duration of colds and supports wound healing and overall immunity.
Food sources:
Good dietary sources of zinc include meat, shellfish, legumes (such as chickpeas and lentils), seeds, and nuts.
Supplement benefits:
Even a mild zinc deficiency can weaken your immune response. Supplementing can be particularly beneficial if you follow a plant-based diet, as zinc from animal sources is absorbed more efficiently by the body.
- Elderberry – The Natural Defender
Why you need it:
Elderberry has been used for centuries as a traditional remedy for colds and flu. Modern research suggests elderberry extracts may help reduce the severity and duration of symptoms thanks to their high antioxidant content and natural antiviral properties.
Food sources:
Elderberries aren’t commonly eaten raw (as they can be toxic when uncooked), but they are often made into syrups, teas, or gummies.
Supplement benefits:
Elderberry supplements are an easy and tasty way to enjoy the benefits without the hassle of preparation. Many come combined with vitamin C and zinc for added immune support.
Stay Strong This Season
Supporting your immune system through proper nutrition is one of the best ways to stay well during cold and flu season. Pairing a balanced diet with high-quality supplements can give your body the extra help it needs to fend off winter bugs — even when everyone around you is under the weather. Your body also needs oxygen… so make sure that you get out in the fresh air!
