General
What is the Gut-X Axis?
Our gut is our body's most immunologically active organ, communicating with different organ systems. What we consume in our gut acts as the entry point to several systemic connections. The gut-X axis denotes the axis or connections by which the gut communicates with various systemic organs or functions. The X could stand for the lungs, such as in the gut-lung axis, the heart in the gut-heart axis, the brain in the gut-brain axis, and so forth.
Who created res?
Our powerful formulas were created by our founder, Dr. Vivek Lal, and his team of double-board-certified, practicing physician-scientists. There's a lot of brainpower behind these powerful formulas. While it should be commonplace, it's rare to have even one physician formulating a supplement, let alone a team. At res, we believe that science speaks for itself, as do the results of physician-crafted supplements!
How long does it take to see benefits?
While people often report gut health benefits as early as their first week, systemic benefits can take longer. Some community members report breathing, circulatory, and energy benefits within six days, while others after 60-90 days. This variability can be attributed to many factors, including the importance of continuous daily use and the reality that some of us constantly think about how our bodies are feeling. In contrast, others go about their day without much thought. Our physicians recommend consistent use for 3-4 months.
Is the shaker bottle dishwasher-friendly?
Yes! The shaker bottle is dishwasher-friendly and BHA-free.
What is your return policy?
We stand behind our supplements and proudly offer a 30-day money-back guarantee on your first purchase. You can read more about our return policy here.
Which certifications does res carry?

Each formulation contains ingredients produced in a cGMP (Current Good Manufacturing Processes) environment by FDA-certified suppliers, specifically processed for extended stability and formula longevity. Additionally, we carry non-GMO Project Verified, kosher, and gluten-free certifications. We’re currently working on publishing our third-party test results and analysis certificates.
