Ready for these 15 supplements for stomach lining support?

So, what is the stomach lining anyways? Maybe we should get this clear before talking about supporting it.

What is the Stomach Lining?

There are three phases of digestion. They include:

  1. The Cephalic phase (oral)
  2. Gastric phase
  3. Intestinal phase

It is in this third phase, the Intestinal phase, where our attention is focused today.

And “technically” the stomach is only part of the upper GI tract.

The digestive system is made up of the gastrointestinal (GI) tract—also called the digestive tract—and the liver, pancreas, and gallbladder. Thus, when I say 15 supplements for stomach lining support, I actually mean, “15 supplements for the GI tract.”

But who needs that much detail anyways?!

What you’re looking for is for me to help you navigate things like:

  1. “I have a leaky gut. What will help strengthen my gut?”
  2. “What supplements can help build my intestinal lining?”
  3. “Are there supplements that will help me tolerate food better?”

And so on.

So let’s dive right on into them.
