THE SCIENCE · FIG. 01

The wall that meets every meal.

The gastric mucosa is the stomach's living inner surface, while the intestinal barrier is the gut's living boundary. Together, they form two distinct parts of the digestive-barrier system GF-1R is formulated to support.

GF-1R / Common questions

Two tissues. One precise scope.

The gastric mucosa belongs to the stomach; the intestinal barrier belongs farther along the digestive tract. The terms are related, not interchangeable.

What does GF-1R support?

GF-1R is formulated for daily support of gastric mucosal wellness, normal gut-barrier function, and everyday digestive comfort. It is a dietary supplement, not a treatment for any medical condition.

What is the gastric mucosa?

The gastric mucosa is the stomach's living inner surface. Epithelial cells, mucus, and glandular secretions work together while the stomach carries out digestion. Read the gastric mucosa guide.

What is the intestinal barrier?

The intestinal barrier is a living epithelial boundary farther along the digestive tract. Its cells, tight junctions, mucus environment, and region-specific secretions help regulate what crosses from the intestine into the body. Compare the two tissues.

What's in GF-1R?

GF-1R contains whole sesame oil, ginseng, and lion's mane. GF-1R does not contain zinc carnosine, L-glutamine, or DGL. The Ingredient Research Library labels ingredient-level, non-human literature separately from finished-product evidence.
