What is dietary fiber?

Dietary fiber is a term used to describe nondigestible carbohydrate substances found in the cell walls of plants. These substances have specific effects on different GI functions. For example, several substances influence the time it takes food to travel through the intestine. Some substances help regulate the amount of water absorbed by the intestine, and others are involved with metabolizing ingested fats. The main types of dietary fiber are bran, mucilage, cellulose, lignin, hemicellulose, pectin, and gum. Soluble fiber helps prevent many problems that can occur in the digestive system by stimulating the regular movement of waste materials through the GI tract.

How does Gastro-Fiber support healthy GI elimination?

Psyllium is a natural laxative and stool softener that is high in soluble fiber.1,2 Apple pectin not only positively affects intestinal bacterial enzyme activity to aid in digestion and promote gut health but is also a soluble fiber that aids in healthy bowel elimination.3, 4, 5*

What ingredients support healthy digestive function?

Fennel stimulates gastric secretions that support a healthy digestive environment and supports gut health.6 As part of ancient healing traditions used on the Indian subcontinent, fenugreek has been used to support healthy digestion and metabolism.7*

Dedicated to the whole food philosophy of our founder, Dr. Royal Lee, our goal is to carry on his mission to provide nutrients for the body that are as close as possible to how they are found in nature.

Our products include foods that are prepared in a way that safeguards their nutritional value. The majority of these ingredients are grown locally on our certified organic farm and may require chopping, dicing, juicing, and/or drying for use in our products. The resulting whole food ingredients are then added to a formula that may include whole food extracts, animal tissue extracts and concentrates, botanicals, whole food isolates, and synthetic ingredients. These highly complex combinations contain a variety of elements designed to trigger trophic effects that support the body’s healthy balance and wellness.*
