Boosting Your Immune System in Winter: The Power of Black Currant

    on January 17, 2024

    Cold and flu season is in full swing for most of us, especially if we live in cold climates, writes Laurel Walker, a mountain athlete and associate editor at

    If you have kids, work at a school, or spend a lot of time traveling, you are probably at a higher risk of catching a cold or the flu. In addition, if you have a hard time sleeping enough and/or are under a lot of stress, your immune system is probably compromised. 

    This article will share several ways to boost your immune system, and how CurraNZ blackcurrant supplements can support your winter strategies. 


    Get Outdoors

    A 2019 study showed that spending 120 minutes a week outdoors can improve your health. That’s just two hours per week total. Make a point to get outside each day, even if it’s for a short amount of time. This can include everything from walking the dog to eating lunch outside, or even taking an evening walk around the neighborhood with your family. 

    Bone Broth 

    Whether you’re headed out for a winter hike or cozying up by the fireplace with your book, a warm cup of bone broth is a great choice for this time of year. It not only helps boost immunity, but it also supports healthy sleep, helps ease joint pain and stiffness, supports a healthy digestion, and boosts your body’s collagen. 


    Sleep is one of the best ways to keep yourself healthy. When we sleep, our muscles repair and our brains reset—there really isn’t a better way to feel regenerated. While exercise is also an important part of staying healthy, if you are sacrificing your sleep to get to the gym every morning, consider choosing a day or two to sleep a little longer and skip the workout, if need be. Your body will thank you in the long run. 

    Vitamin C 

    Vitamin C is important to help us keep our immune systems strong. Fruit is rich in vitamin C and is a great way to get this important vitamin in. Or, if you are craving something warm, you can mix Emergen-C with hot water for a nice, immunity-boosting treat. This is also a great drink to bring with you if you are heading outdoors to hike, run, climb, or ski. Lemon and honey in hot water or tea is another great way to get in your vitamin C in a soothing, comforting way. 

    In addition, echinacea and black currant are also powerful antioxidants and immunity boosters. Both can be purchased in pill form and taken throughout the winter, or even the year. Below we will dive a bit deeper into CurraNZ blackcurrant supplements. 


    Unlocking the Immunity-Boosting Power of CurraNZ New Zealand Black Currant Supplements

    Antioxidant Powerhouse

    These berries are packed with antioxidant sources anthocyanins and quercetin, which help combat oxidative stress. Oxidative stress can weaken the immune system, and by consuming antioxidants, individuals can fortify their body's defense mechanisms.

    Anti-Inflammatory Properties

    New Zealand Blackcurrant has been studied for its anti-inflammatory effects. Chronic inflammation can compromise the immune system, and the anti-inflammatory properties of blac currants may contribute to a more balanced and responsive immune system, while helping manage inflammation generated from strenuous exercise.

    Enhanced Microcirculation

    The anthocyanins found in black currants are linked to improved microcirculation. Adequate blood flow is essential for the efficient transportation of immune cells throughout the body, ensuring a swift response to potential threats.

    Anti-viral activities

    Blackcurrant can help boost anti-viral defences, with multiple studies showing their potent anti-viral effects, by helping act as a ‘disinfectant’ in cells. The extract inhibits absorption onto cell surfaces, helps to impair viral growth and release by infected cells and inhibiting the viral life cycle.     

    CurraNZ is an amazing option for anyone wanting to fortify their immune system. With its anti-viral, antioxidant, and anti-inflammatory properties, this unique berry offers an holistic approach to supporting overall immune health.
