Feature summary

Natural Factors Critical Care Probiotic 100 Billion Active Cells is a 9-strain formula that includes five strains of Bifidobacteria and four strains of Lactobacilli, providing powerful support for gastrointestinal and immune system health. This potent one-a-day formulation includes L. paracasei, L. rhamnosus, L. acidophilus, L. plantarum, and B. bifidum, proven to help eliminate or reduce the growth of methicillin-resistantStaphylococcus aureus (MRSA) and to lower incidence ofClostridium difficile-associated diarrhea.

This multistrain formula can quickly restore the diversity of microflora after antibiotic use, with L. acidophilus particularly helpful in counteracting antibiotic-associated diarrhea, abdominal cramps, and constipation.

The probiotic strains L. paracasei, L. acidophilus, B. animalissubsp. lactis, B. bifidum, and B. longum have been shown to help reduce the production of pro-inflammatory substances and to alleviate the gastrointestinal effects of psychological stress. Reducing inflammation can help in the management of irritable bowel syndrome (IBS) and food intolerances. Beneficial gut bacteria also play a role in the prevention and management of yeast overgrowth and urinary tract infections.

Each strain in this formulation has been carefully selected for its natural resistance to gastric acid, allowing the probiotics to reach the intestines at full potency. Critical Care Probiotic 100 Billion Active Cells has a guaranteed potency of 180 billion active cells per capsule at manufacture and at least 100 billion at expiry.

Main selling features

  • Formulated to provide critical care for acute needs
  • Replenishes good bacteria and combats antibiotic-associated gastrointestinal distress
  • L. paracasei and L. acidophilus improve resistance to MRSA,Clostridium difficile, and other opportunistic pathogens
  •  Includes L. rhamnosus and B. longum, which enhance immune function, and B. animalis subsp. lactis, which reduces the production of pro-inflammatory substances
  • Provides intense support to the small intestine, where 90% of digestion takes place
  • Guaranteed potency of 100 billion colony forming units, even at expiry

The diversity of gut microflora not only affects gastrointestinal health, but also the immune function; our resistance to pathogenic infection; and the adverse effects of stress on digestive health.

When antibiotics, stress, and dietary and lifestyle factors adversely affect the populations of good bacteria in our gut, we are placed at increased risk of infectious and noninfectious diseases, including methicillin-resistant Staphylococcus aureus,Candida albicans, and Clostridium difficile. These pathogens can cause increased inflammation and tissue damage throughout the body, gastrointestinal symptoms such as severe diarrhea, and other systemic effects such as yeast overgrowth and compromised immune function.

Bifidobacteria are the most prevalent friendly bacteria in the large intestine, while Lactobacilli are the main beneficial strain in the small intestine. They work together to maintain an effective intestinal barrier against pathogens; to reduce the production of pro-inflammatory substances; and to stimulate phagocytes, dendritic cells, and other immune system cells to destroy foreign organisms. These probiotics help maintain conditions in the gut that are unfavourable for pathogenic infection.
