A healthy gut microbiome benefits digestion, immunity, mood, and overall well-being. Its delicate balance is easily disrupted by factors such as stress, antibiotics, illness, and age-related declines. Probiotics contain active cultures of beneficial bacteria and yeast that help maintain and re-establish a healthy gut microbiome. Natural Factors’ line of probiotic supplements contain Lactobacillus, Bacillus, Enterococcus, and Saccharomyces strains in synergistic combinations for different age groups, health concerns, and lifestyle.
