5 Effective Vitamins to Take This Winter 

As winter approaches, protecting your immune system against the seasonal onslaught of colds, flu, and other illnesses is essential.

While maintaining a healthy lifestyle is crucial all year round, certain vitamins can provide an extra layer of defence during the colder months. Here are three powerful vitamins that can help supercharge your immunity and keep you feeling your best this winter. 

Which Vitamins Should You Take in Winter? 

1. Vitamin C to Boost the Immune System

Vitamin C is known for its immune-boosting properties, helping to support the body’s natural defence mechanisms against infections. Vitamin C with liposomal delivery can be particularly beneficial. Liposomal technology is a process whereby nutrients are delivered into the body through encapsulated liposomes, protecting them from degradation before entering the bloodstream, and allowing them to reach bodily cells more efficiently.

This enhances the bioavailability of the vitamin C and makes it more easily absorbed. Additionally, vitamin C acts as a powerful antioxidant, scavenging harmful free radicals that can contribute to cellular damage and inflammation, which can increase during winter due to factors like indoor heating and exposure to cold weather. By taking vitamin C with liposomal delivery, individuals can strengthen their immune systems and improve their overall health during winter (1). If you are looking for a great vitamin C option with increased absorption, try Coyne Biomax Vitamin C Liposomal. 

2. AHCC for Optimal Immune function 

AHCC (Active Hexose Correlated Compound) is a unique extract derived from the mycelia of Shiitake mushrooms. AHCC harnesses its immune-boosting power to support overall health and well-being, particularly during the colder months. With over 100 published studies, AHCC is known for its ability to enhance the activity of natural killer (NK) cells, which are crucial for immune surveillance and defence against pathogens.

AHCC helps the body fight infections and maintain optimal immune function by activating NK cells and other immune cells. Incorporating AHCC into your daily regimen can provide added protection against winter ailments and promote overall immune resilience (2). Try Coyne AHCC Mycelia Extract to give your immune function a much-needed boost. 

3. Beta Glucans to Fight Infections & Oxidative Stress 

Beta glucans are polysaccharides found in various mushrooms, oats, and yeast, known for their ability to modulate the immune system and enhance its response to infections. Beta-glucans possess antioxidant properties, which can help neutralise harmful free radicals and reduce oxidative stress in the body. By reducing oxidative damage, beta-glucans indirectly support immune function.

Astragalus, a traditional Chinese herb, has been used for centuries to support immune function and promote vitality. Beta-glucan mixed with astragalus, as well as vitamin C, offers a synergistic blend of immune-supportive nutrients to help you stay healthy and resilient throughout the winter season (3). Try Terranova Beta Glucans & Astragalus and Vitamin C to give your body the extra strength it needs to fight infections and improve oxidative stress.  

4. Quercetin’s Anti-inflammatory & Antioxidant Properties 

Quercetin is a powerful antioxidant and anti-inflammatory that helps to neutralise free radicals and decrease inflammation. It has been found that Quercetin’s strong antioxidant and anti-inflammatory properties can help reduce the risk of infections and enhance immune response, and, in-turn keep one healthy during the cold and flu season. If you are looking for extra protection for your immune system, try Phytopure® Quercetin with Pomegranate and experience its powerful anti-inflammatory and antioxidant effects too! 

5. Wanting To Support Your Child’s Immune System? 

Protecting your kid’s immune system during cold and flu season is crucial for their overall health and well-being. A balanced diet rich in vitamins and minerals is essential, but sometimes additional support is needed. Multivitamins can help fill nutritional gaps, ensuring children get essential vitamins which are vital for immune function.

These vitamins support various aspects of the immune response, enhancing the body’s ability to fend off infections and recover more quickly if they do get sick. Try Nutriburst SuperKidz Multivitamin and have the peace of mind that your child’s immune system is at its best when cold and flu season comes around. 

Not only is the cold and flu season unbearable for many, but when combined with other everyday factors such as stress and anxiety, it can further weaken the immune system. By taking the correct supplements, you can have peace of mind knowing that your body will stay healthy and possibly fight off any infections that might have otherwise come your way!
