CodonRX® was created to make high-quality, science-backed health products more affordable and accessible—not just in the U.S., but globally.

Our flagship product, CodonRX® | AI, features the patented NCK2025™ strain of Lactobacillus acidophilus, a probiotic known for its anti-inflammatory (AI) properties. This strain removes inflammatory fatty acids from bacterial surfaces, helping to reduce gut inflammation.

At CodonRX®, we believe that cutting-edge scientific advancements should be both effective and accessible.

CodonRX® | AI promotes overall gut health and may help alleviate symptoms like bloating, constipation, and diarrhea. It may be particularly beneficial for individuals with IBS (Irritable Bowel Syndrome) and inflammatory bowel conditions.

Take two flavorless capsules daily, with or without food. You may adjust usage as needed.

The primary active ingredient in CodonRX® | AI is our patented Lactobacillus acidophilus NCK2025™ strain, scientifically shown to support gut health.

Results vary from person to person, but most users report noticeable improvements within 30 days. Consistency is key, and factors like diet, lifestyle, and sleep may also affect results.

Our probiotic strain, Lactobacillus acidophilus NCK2025™, is Generally Recognized As Safe (GRAS) under FDA guidelines and is safe for human consumption.

For best results, store CodonRX® in the refrigerator to maintain potency. If refrigeration is not possible, store it in a cool, dry place away from direct sunlight.

CFU (Colony-Forming Units) is a measure of the number of live bacteria in a probiotic. While many brands advertise high CFU counts in the tens of billions, this number alone doesn’t determine a probiotic’s effectiveness.

Here’s the truth about CFUs:

• CFU count matters—but only when it applies to a single, proven strain. Many probiotics combine multiple strains into one formula, but the CFU count often reflects the total across all strains, not just the one that delivers the intended health benefits. In some cases, the most beneficial strain makes up only a small fraction of the reported CFU count.
• More strains don’t always mean better results. Multi-strain probiotics can be effective, but if you're targeting a specific health concern—like gut inflammation—it’s essential to choose a probiotic with a clinically studied strain at the right dosage.

Unlike generic probiotics that rely on a high CFU count across multiple strains, CodonRX® focuses on a single, patented, and scientifically backed strain—NCK2025™—designed to actively reduce gut inflammation and provide real symptom relief.

CodonRX is the only probiotic on the market that contains the patented NCK2025™ strain of Lactobacillus acidophilus, scientifically proven to reduce gut inflammation—one of the root causes of digestive issues like constipation, bloating, gas, abdominal pain, and diarrhea.
