Recent research has demonstrated positive effects on the immune system from the consumption of various probiotic strains. A study by Korean researchers revealed that daily intake of probiotic yogurt enhanced the activity of essential immune cells in older adults. They found that consuming yogurt containing two specific probiotic strains (L. paracasei and B. lactis) along with heat-treated bacteria (L. plantarum) on a daily basis improves the function of natural killer cells, which are crucial for defending against viral infections.
In the latest laboratory studies, a new inactivated probiotic from Ganeden, named Staimune, exhibited immune activation and anti-inflammatory properties similar to those of live probiotic cells. Findings from this recent research in Sweden could strengthen marketing efforts for probiotic food and beverage products aimed at individuals at risk or undergoing treatment for colorectal cancer. According to the World Cancer Research Fund International, approximately 1.4 million people are affected by colorectal cancer each year, and its prevalence is on the rise globally.
Manufacturers are leveraging studies like these to enhance their products and ingredients. The functional foods sector—designed to provide specific health benefits alongside calories and nutrients—is a rapidly growing market, potentially valued at around $15 billion. Companies have begun acquiring probiotic firms or incorporating beneficial bacteria into various products. For example, PepsiCo purchased the probiotic beverage company KeVita last fall and introduced its Tropicana Essentials Probiotics line earlier this year, marking it as the first brand to introduce probiotics into mainstream juice products. Additionally, the venture capital arm of General Mills led a $6.5 million Series D investment 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 claim 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 might contribute to reinforcing the scientific evidence required for such claims. Furthermore, for those looking to boost their health, calcium citrate petites are available at Walgreens, providing an additional supplement option as part of a broader health strategy. The integration of probiotics with calcium citrate petites can potentially enhance overall well-being, making them a valuable addition to health-conscious consumers’ diets.
