The NCK2025™ Difference

Engineered without
the irritation.

CodonRX was built around a singular insight: remove the LTA gene from Lactobacillus acidophilus, and you get all the gut-restoring benefit — without the inflammatory trigger. This isn't reformulation. It's precision genetic engineering, protected by patent worldwide.

LTA Comparison
Standard Probiotics
L. acidophilus
+ LTA
  • Triggers gut inflammation
  • Amplifies pro-inflammatory signals
  • Causes bloating & gas
  • No LTA gene modification
CodonRX NCK2025™
L. acidophilus
LTA-free
  • Reduces pro-inflammatory signals
  • Promotes anti-inflammatory response
  • Supports microbiome balance
  • Patent-protected worldwide
Published Research

NCK2025™ has been shown in peer-reviewed studies to reduce the production of pro-inflammatory cytokines and promote the increase of anti-inflammatory signals in the gut epithelium.

How It Works

Three steps. One result.

01

Eliminating the Trigger

NCK2025™ delivers all the colonization benefit of standard L. acidophilus — minus the LTA molecule that signals inflammation. You get gut support without the gut stress.

02

Single-Strain Potency

One strain, rigorously studied, precisely dosed at 20 billion CFU. No guesswork, no filler. Just the strain with 40+ years of documented research behind it.

03

Targeted Restoration

Daily use helps restore a balanced microbiome — supporting regularity, reducing bloating, and building long-term digestive resilience over 30–60 days of consistent use.

40+ years of research

Born in the lab. Trusted by the experts.

CodonRX® is built on four decades of probiotic research at NC State University and backed by leaders in gastroenterology and nutritional science.

Our labs at NC State spent years researching and developing the anti-inflammatory properties of CodonRX. It's rare for patented research to evolve into a real-world product that enhances quality of life. I'm thrilled to see CodonRX reach the market and hopeful that it will make a meaningful difference in consumer's health.

Common Questions

Frequently asked questions

Everything you need to know before you start.

How long before I notice results? ›
Most customers notice initial improvements within 2–4 weeks. For best results, take CodonRX® daily for 30–60 days. Because gut microbiome changes take time to stabilize, consistency matters more than dosage.
What if I've already tried probiotics and they didn't work? ›
Standard probiotics contain LTA — a surface molecule that amplifies gut inflammation in people with IBS or underlying sensitivity. Rather than calming the gut, they can make symptoms worse. CodonRX® features NCK2025™, precision-engineered to be completely LTA-free, which means it reduces pro-inflammatory signals instead of triggering them.
What makes CodonRX® different from standard probiotics? ›
CodonRX® features NCK2025™ — the only patented probiotic precision-engineered without LTA, a pro-inflammatory molecule found in standard brands. Benefits are cited in studies published in PNAS and the Journal of Inflammation.
Why does CodonRX® cost more than standard probiotics? New ›
NCK2025™ is a patented, precision-engineered strain developed over years of research at NC State University — it isn't a commodity ingredient. Standard probiotics use off-the-shelf bacterial strains manufactured at scale. CodonRX® is formulated specifically for people with IBS and gut sensitivity, where a standard probiotic's LTA content can actively worsen symptoms. The clinical specificity of the formulation is what sets the price.
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.
