The CodonRX difference
Engineered for people failed by other probiotics
Standard probiotics were designed for general wellness. CodonRX® was designed specifically for people with IBS and underlying gut sensitivity.
1
Most probiotics carry LTA
Standard strains carry LTA (lipoteichoic acid) on their surface — a molecule that may worsen gut sensitivity.*
2
More strains can mean more of it
Multi-strain formulas combine many standard strains, and each one brings its own LTA.
3
NCK2025™ is engineered without it
Through precision engineering, NCK2025™ is the only probiotic engineered without LTA. One strain, nothing extra. Only from CodonRX®.
Typical probiotic strain

Before you order
Common questions about your order, subscription, and what to expect.
How is CodonRX® different from the probiotic I tried before?
Most probiotics combine several standard strains, each carrying LTA (lipoteichoic acid), a surface molecule that may worsen gut sensitivity.* CodonRX® uses one strain, NCK2025™, engineered without LTA, and every capsule is individually sealed.
What if it doesn't work for me?
Your first order is covered by our 60-day satisfaction guarantee. You have 30 days to finish your first carton, plus an extra 30 days to decide. If you aren't satisfied, email contact@codonrx.com with your order number for a full refund. No returns required. Applies to first orders in the U.S.; see our full terms.
How do I take CodonRX®?
Take 2 capsules once daily, with or without food. Refrigerate after opening to maintain potency. Each carton contains 60 capsules — a 30-day supply.
How long before I see results?
Many customers notice changes within 2–4 weeks.* For best results, take CodonRX® daily for 60 days. Consistency matters more than timing.
Can I cancel my subscription anytime?
Yes. Subscription orders renew and ship automatically every 30 days, and a reminder email is sent 5 days before each renewal. Subscriptions can be cancelled at any time with no fees or penalties. You can manage or cancel your subscription from your account dashboard or by contacting our support team before your next billing date.
Is there an adjustment period?
Some customers experience mild, temporary gas or bloating during the first few days as their gut microbiome adjusts. This typically settles within the first week. If symptoms are severe or persist beyond two weeks, discontinue use and consult your healthcare provider.
How is CodonRX® shipped and stored?
CodonRX® ships Mondays to Wednesdays via standard FedEx 2 day with specialized packaging designed to absorb heat. Rest assured the product is temperature stable. Each capsule is individually foil-sealed for stability in transit. Once received, refrigerate the carton to maintain peak potency through the best-before date printed on the box.
Is CodonRX® safe to take with other supplements or medications?
CodonRX® is vegan, allergen-free, and contains no dairy, gluten, soy, or nuts. As with any supplement, if you are taking prescription medications or have a medical condition, consult your healthcare provider before use.
