As the gut health trend continues to grow, the probiotic market has exploded—it was valued at $87.7 billion in 2023. Probiotic supplements—beneficial live bacteria and yeasts—can seem appealing if you’re looking to improve gut health, or how well your digestive system is working to break down food, absorb nutrients, and eliminate waste. Probiotics can also help strengthen the gut microbiome, made up of trillions of microorganisms including bacteria, viruses, and fungi that are vital in nutrient absorption, digestion, and overall health.
