FloraSport 20B Probiotic Supplement - Shelf-Stable Digestive Support

Our review of FloraSport 20B finds it best suited for active people and anyone seeking reliable, shelf-stable digestive support; the single biggest reason to buy is its 20 billion CFUs per capsule that remain stable at room temperature up to expiration, which removes the hassle of refrigeration while still supporting gut flora and occasional digestive upset. The product also stands out because it is NSF Certified for Sport, making it a sensible option for athletes who need a probiotic tested against a wide list of banned substances.
