10 Natural Products to Boost Your Immunity During the Change of Seasons
For our complete supplements selection
With temperatures fluctuating and flu season in full swing, our immune systems are facing extra challenges. Here are ten natural products to help you stay healthy all winter long.
1. Echinacea
Known for its anti-inflammatory, antiviral, and antibacterial properties, echinacea supports the immune system by enhancing the body’s natural defences. Taken as a preventive measure or at the first signs of a cold or flu, it helps reduce the risk of complications caused by respiratory tract infections.
2. Zinc
Zinc is essential for a strong immune system, as it supports the production and proper functioning of immune cells. It also helps repair skin tissue—the body’s first line of defence against infection. Zinc deficiencies can weaken the immune system and delay healing, making the body more vulnerable to disease.
3. Vitamin D
Vitamin D is needed to activate T cells and macrophages, and plays a key role in protecting your body from infection. It also helps maintain a healthy intestinal wall, which prevents pathogens from entering the bloodstream. Since vitamin D is primarily synthesized through sun exposure, taking supplements can be particularly beneficial for addressing deficiencies during the winter.
4. Astragalus
This adaptogenic plant has long been used in Chinese medicine to help prevent respiratory infections and boost the body’s natural defences. Astragalus root is commonly used to treat colds, flu, chronic bronchitis, and hay fever. It’s also beneficial during periods of high stress or fatigue.
5. Elderberry
Found in the wild in Quebec, elderberries are known for their antiviral and anti-inflammatory properties. Rich in vitamins and polyphenols, they have twice as many antioxidants as blueberries. Elderberries also help protect cells from oxidative stress and prevent seasonal infections, including colds and flu.
6. Vitamin C
Vitamin C plays an active role in supporting the immune system by stimulating the production of defence cells and safeguarding them from damage caused by free radicals. Since the body cannot produce vitamin C on its own, it’s important to consume foods rich in this nutrient, such as citrus, or take supplements to avoid deficiencies.
7. Reishi mushrooms
Used in traditional Asian medicine, reishi mushrooms are known for their immunomodulatory and anti-inflammatory properties. By stimulating the production of white blood cells, they enhance the immune system’s ability to combat respiratory infections while also improving resistance to stress and fatigue.
8. Garlic
Garlic is a true superfood. With its antibacterial, antiviral, and antifungal properties, it promotes the growth of good intestinal bacteria and activates immune cells to help prevent respiratory infections. To reap the maximum benefits, experts recommend eating one clove of raw garlic per day. Garlic supplements are also a convenient alternative for those who want to avoid bad breath!
9. Probiotic
Probiotics help keep our gut microbiota healthy, which is important because the gut is home to a great many of our immune cells. By encouraging the growth of good bacteria and strengthening the intestinal wall, they prevent pathogens from entering the bloodstream while improving digestion and boosting the body’s natural defences.
10. Propolis
Bee propolis has been used for centuries for its antiseptic and immunomodulating properties. It helps fight respiratory infections and soothe symptoms, such as sore throats and coughs. Thanks to its powerful antioxidants, propolis not only boosts the immune system but also serves as an excellent shield against seasonal ailments.
