Description
Natural Factors Critical Care Probiotic 55 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 formulation includes L. paracasei, L. rhamnosus, L. acidophilus, L. plantarum, and B. bifidum, proven to help eliminate or reduce the growth of methicillin-resistant Staphylococcus aureus (MRSA), and to lower incidence of Clostridium 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. animalis subsp. 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 55 Billion Active Cells has a guaranteed potency of 95 billion active cells per capsule at manufacture and at least 55 billion at expiry.
Frequently Asked Questions
What is Natural Factors, and is it a trustworthy supplement brand?
Natural Factors is a Canadian-owned supplement manufacturer founded in 1948 and headquartered in Coquitlam, British Columbia. One of North America's largest supplement makers, it operates over 1,000 acres of certified organic farmland in BC's Okanagan Valley and manufactures in-house at Health Canada-licensed, FDA-inspected facilities. Every product is third-party tested through ISURA for over 800 contaminants including pesticides and heavy metals. Natural Factors is also B Corp certified, meeting rigorous environmental and social standards.
What is Natural Factors and is it a reliable Canadian supplement brand?
Natural Factors is one of Canada's largest supplement manufacturers, founded in 1955 by Jack and Rona Katz in British Columbia and still 100% Canadian family-owned. The company controls every production stage from raw material sourcing to finished product. Its facility holds TGA certification from Australia's Therapeutic Goods Administration, one of the world's strictest supplement manufacturing standards. All products are ISURA certified — independently tested for 800+ contaminants including pesticides and heavy metals — and Natural Factors conducts four rounds of product testing, double the industry average of two.
What sets Natural Factors apart from other supplement brands?
Natural Factors' most distinctive quality is vertical integration: the company grows its own raw herbs on 1,000+ acres of certified organic farmland in BC's Okanagan Valley, then processes and manufactures in-house. Most supplement brands source raw materials from external suppliers with no direct agricultural control. Natural Factors also uses ISURA third-party testing, a Canadian standard that screens for over 800 contaminants, well beyond typical heavy-metal panels. B Corp certification further reflects a documented commitment to environmental and social accountability, not just a marketing claim.
What makes Natural Factors different from other Canadian supplement manufacturers?
Natural Factors holds TGA certification from Australia's Therapeutic Goods Administration — one of the world's most rigorous pharmaceutical manufacturing standards, rarely earned by Canadian brands and far exceeding most North American certification requirements. Its ISURA testing program screens every product for 800+ contaminants, and it conducts four rounds of quality testing per product versus the industry standard of two. The company also operates its own farm in the Okanagan Valley for select botanical ingredients — a level of vertical integration uncommon among supplement manufacturers — and has been family-owned for over 70 years.
