We will explore the science of NOW Respiratory Care Probiotic. Respiratory Care Probiotic is a probiotic combination featuring L. acidophilus NCFM®, which has been used in over 60 scientific studies. When used alone or in combination with B. lactis Bl-04, NCFM® has been shown to support a robust and balanced immune response to seasonal respiratory challenges, as well as to support an active lifestyle. NCFM® can rapidly populate the intestine and adhere to the intestinal wall, which is helpful for use during and after temporary disruptions to intestinal microbiota. Remember, nutrients are not drugs and do not treat diseases like respiratory allergies. Supplements like probiotics are natural bacteria that provide a functional benefit that supports respiratory health. Don't confuse nutritional support with drugs. They are not the same.
