Put most simply, the immune system is the body’s defense system against infections. It is the the bodily system that protects us from foreign substances, cells, and tissues, and it works around the clock to prevent us from getting sick. In reality, the immune system is much more complex and can be influenced by many different outside factors, from how much rest we are getting to the foods and supplements we put in our body. The immune system health market was already booming pre-coronavirus pandemic, grossing over $18 billion in 2020 alone. Since then, it has only continued to grow as many people are on the lookout for effective products that they think will boost their immune systems and strengthen their body’s capabilities to defend itself. The industry is expected to reach a staggering $31.5 billion by 2028. Many people rank immune system health right behind physical fitness and cognitive health, but what goes into sustaining a healthy immune system exactly? People often hear of “immune-boosting diets" and “superfoods” claiming to be packed with natural ingredients, and while these foods can contribute to good overall health, the agreement on what is perceived by the general public as being effective at boosting immunity and what science shows to be proven immune health ingredients is not always clear. Three immunity ingredients that are tried, proven, and trusted by Vesta Nutra are Beta Glucan, Fucoidan, and ImmuneNK. We’ll break down these ingredients below: [**Beta Glucan**](https://vestanutra.com/vproducts/beta-immuneshield/)is the strongest immunomodulator out there. When beta-glucan is consumed, key immune cells called Neutrophils and Macrophages are activated. What that means is that this one power-packed ingredient expands and intensifies all the functions within the immune system. Beta Glucan makes the immune system more active and alert which makes it more effective at fighting off bacteria, viruses, parasites, and fungi. [**![Beta Glucn](https://blog.vestanutra.com/hs-fs/hubfs/Canva%20images/Witness%20your%20team%20battle%20it%20out%20from%20February%202-4!.png?width=1080&name=Witness%20your%20team%20battle%20it%20out%20from%20February%202-4!.png)**](https://blog.vestanutra.com/nutralink/4-ways-beta-glucan-helps-the-body-beyond-boosting-immunity) [**Fucoidan**](https://vestanutra.com/vproducts/ultrafucoidan/)is a sulfated polysaccharide that naturally occurs in seaweed and has had a long- standing history in medicinal use for its immune reinforcing activity. Fucoidan boosts the activity of antigen-presenting cells, which act as gatekeepers and messengers between innate and adaptive immunity. This helps facilitate a more optimal function between this cross-talk by assisting in innate immune activity. [![UltraFucoidan](https://blog.vestanutra.com/hs-fs/hubfs/Canva%20images/UltraFucoidan%20image.png?width=940&name=UltraFucoidan%20image.png)](https://info.vestanutra.com/download-the-ultrafucoidan-brochure) [**ImmuneNK**](https://vestanutra.com/vproducts/immunenk/)is a blend of immunity ingredients that work in synergy with your immune system to activate the body’s innate immune surveillance system and provide effective immunoprotection. ImmuneNK provides important nutrients and antioxidants to the immune system helps curb negative inflammation in the body and is scientifically designed to optimally support immune function when you need it, like during cold and flu season. [![ImmuneNK](https://blog.vestanutra.com/hs-fs/hubfs/Canva%20images/ImmuneNK%20FB%20post.png?width=940&name=ImmuneNK%20FB%20post.png)](https://info.vestanutra.com/download-immunenk-brochure) The immune system is one of the body’s most complex and important systems, and making sure it’s being supported in the right way is essential to good immune system health. Getting enough rest and eating a variety of nutritionally dense foods is a good way to make sure your immune system is staying healthy, but adding an immunity ingredient to your diets such as Beta Glucan or ImmuneNK can be a great way to supplement your immune system health and ensure it is functioning at its best.
