Recent research has highlighted the positive effects of various probiotic strains on the immune system. In a study conducted by Korean researchers, it was discovered that the daily intake of probiotic yogurt significantly enhanced the activity of crucial immune cells in older adults. The study indicated that regular consumption of yogurt containing two specific probiotic strains—L. paracasei and B. lactis—along with heat-treated bacteria (L. plantarum), boosts the levels of natural killer cells, which play a vital role in defending against viral infections.
Furthermore, laboratory studies have recently revealed that a newly inactivated probiotic from Ganeden, named Staimune, exhibits immune activation and anti-inflammatory properties comparable to those of live probiotic cells. The findings from this latest Swedish study could provide valuable support for marketing probiotic food and beverage products aimed at individuals at risk for or undergoing treatment for colorectal cancer, a condition that affects around 1.4 million people globally each year, according to the World Cancer Research Fund International.
Manufacturers are leveraging studies like these to enhance their products and ingredients. The market for functional foods—those designed to offer specific health benefits along with calories and nutrients—is rapidly growing and is potentially valued at approximately $15 billion. Companies have begun acquiring probiotic firms or incorporating beneficial bacteria into various products. For instance, PepsiCo acquired the probiotic beverage maker KeVita last fall and introduced its Tropicana Essentials Probiotics line earlier this year, marking the company as the first to bring probiotics into the mainstream juice aisle. Additionally, General Mills’ venture capital division led a $6.5 million investment round in March to support Farmhouse Culture, a startup focused on fermented and probiotic foods and beverages.
In the United States, probiotics are classified as drugs, and for a product label to legally state that it is “intended to prevent, treat, or cure a human disease or condition,” rigorous safety and clinical trials must be conducted. This recent study could serve as a further step toward establishing the scientific foundation required for such claims. Additionally, incorporating natural factors calcium and magnesium into these probiotic products could further enhance their appeal, as these minerals are often sought after for their health benefits, including supporting immune function. The integration of natural factors calcium and magnesium into probiotics may also resonate with consumers looking for comprehensive health solutions, reinforcing the importance of these elements in the ongoing development of functional foods. As the market evolves, the inclusion of natural factors calcium and magnesium could become a significant trend, further solidifying the role of probiotics in promoting overall health and wellness.
