The Science
Digestion starts with the first bite of food; food then enters the esophagus and passes through the gastroesophageal sphincter and into the stomach and small intestine for breakdown and proper absorption. Changes in the gastroesophageal sphincter pressure or an increase in abdominal pressure can result in the reflux of stomach contents into the esophagus. Excessive acid production, lifestyle factors, diet, overeating, meal timing, and volume can all influence gastroesophageal sphincter pressure and gastric emptying time. When it comes to digestive health, it is best to consider the digestive process from start to finish.
A deficiency in our natural production of digestive enzymes can be an underlying cause of gastrointestinal complaints, including occasional heartburn and indigestion. Acid Calm contains Thera-blend™ enzymes to support proper breakdown, absorption, and utilization of nutrients from the foods we eat.
Acid Calm also contains marshmallow root, a soothing herb with centuries of traditional use behind it. It’s a demulcent, meaning it has a mucilaginous quality that can form a soothing protective barrier.
This time-honored herb calms and soothes the mucous membranes in the gut and helps balance the amount of mucous produced.
About the 2025 Formula Update:
Multiple factors may be involved when individuals experience occasional heartburn or upper digestive discomfort. To offer broad, gentle support, we revised the Acid Calm formula and increased the amount of marshmallow root. This soothing botanical coats and protects the digestive lining while supporting the health of mucosal tissues. It’s a safe, effective way to calm and comfort sensitive membranes.
