Several ingredients such as colostrum, yeast and beta-glucans, omega-3s and probiotics are making their way into formulations for immune health support.

Colostrum

According to a 2018 review published in Frontiers in Nutrition, “It was first shown in the 1960s that bovine colostral immunoglobulins protected calves against gastrointestinal [GI] bacterial and viral infections.”¹ That discovery led to human clinical studies, a large number of which the review noted “have now shown efficacy of bovine immunoglobulins in preventing natural infection in humans as well as in animal infection models.”

Yeast and beta-glucans

Beta-glucans and yeasts—often found in foods like shiitake mushrooms, cereals and baker’s yeast—are proving useful in supporting a healthy immune system. A 2021 study from Molecular Nutrition & Food Research concluded, “There is emerging evidence that dietary components, including yeast-derived beta-glucans, can aid host defense against pathogens by modulating inflammatory and antimicrobial activity of neutrophils and macrophages.”²

Omega-3s

A 2019 review noted that a healthy and balanced diet is important to help support the immune system—calling out the benefits of omega-3s specifically.³ It elaborated, “The impact of dietary polyunsaturated fatty acids (PUFAs) on the immune system has been investigated for decades, with special focus on the omega-3 PUFAs alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)… Both omega-3 and omega-6-derived metabolites have important immune-regulatory functions.”

Probiotics

A review published in the journal Current Opinion in Gastroenterology noted, “The beneficial effects of probiotics have been demonstrated in many diseases.⁴ One of the major mechanisms of probiotic action is through the regulation of host immune response.” Although further research on this relationship is needed, the article concluded, “Probiotics may provide novel approaches for both disease prevention and treatment.”
