Numerous recent studies have indicated that various strains of probiotics can positively impact the immune system. Korean researchers discovered that the daily intake of probiotic yogurt enhanced the activity of essential immune cells in older adults. They found that consuming yogurt with two specific probiotic strains (L. paracasei and B. lactis) along with heat-treated bacteria (L. plantarum) daily boosts the activity of natural killer cells, which are crucial for offering strong defense against viral infections.
Additionally, recent laboratory studies revealed that a new inactivated probiotic from Ganeden, known as Staimune, exhibited similar immune activation and anti-inflammatory properties as live probiotics. Findings from this latest Swedish study could significantly support the marketing of probiotic food and beverage products targeted at individuals at risk of or undergoing treatment for colon cancer. According to the World Cancer Research Fund International, approximately 1.4 million people worldwide are affected by colorectal cancer each year, a number that continues to rise.
Manufacturers are increasingly leveraging studies like these to enhance their products and ingredients. The functional foods sector—which aims to provide specific health benefits alongside calories and nutrients—is rapidly growing and could be worth an estimated $15 billion. Companies have started acquiring probiotic firms or incorporating beneficial bacteria into various products. For instance, PepsiCo purchased the probiotic beverage company KeVita last fall and introduced its Tropicana Essentials Probiotics line earlier this year, making it the first brand to integrate probiotics into the mainstream juice market. Moreover, General Mills’ venture capital division led a $6.5 million Series D investment round in March to support Farmhouse Culture, a startup specializing in fermented and probiotic foods and beverages.
In the United States, probiotics are categorized as drugs, requiring rigorous safety and clinical trials for any product label to legally claim it is “intended to prevent, treat, or cure a human disease or condition.” This recent study could serve as another step towards strengthening the scientific foundation necessary for such claims. Additionally, the inclusion of liquid calcium and magnesium in probiotic formulations may further enhance their appeal and effectiveness, as these minerals are often sought after for their health benefits. The integration of liquid calcium and magnesium could potentially offer consumers a more comprehensive approach to supporting their immune health, especially when combined with probiotics.
