Nonprescription FDgard® is specially formulated with a combination of caraway oil and l-Menthol (the primary component of peppermint oil). Clinical studies have shown that this combination of ingredients can help manage the syndrome of FD symptoms1. But how exactly do these natural ingredients combine to produce calming digestive results? Through the science of dual and synergistic action!

Caraway oil in combination with peppermint oil (primary component: l-Menthol) is intended to serve as a fundus relaxant as part of the gastro-duodenal reflex2. The fundus is the upper-most part of the stomach. It stores undigested food and gases that are released during digestion. In order to accommodate these materials, the fundus must adapt (relax). According to one study, impaired fundus accommodation was found in 40% of Functional Dyspepsia cases3.

L-Menthol, the primary component in peppermint oil, acts as an analgesic for pain and as an anti-spasmodic for cramp reduction. Its anti-spasmodic function is designed to combine with the fundus relaxant caraway oil, resulting in synergistic action. Put another way, these ingredients are designed to work together and separately to encourage the natural movement of food through the digestive tract2. Functional Dyspepsia is largely a disorder of movement, meaning the stomach does not expand normally in response to ingested food. The natural ingredients found in FDgard are specially formulated to target the site of the digestive disturbance, to help restore the natural rhythm of the digestive system.
