Protein plays an important role in digestive health by supplying the amino acids your body needs to maintain and renew tissues throughout the gastrointestinal tract. Because the cells lining the intestines naturally turn over quickly, consuming adequate protein helps support this ongoing renewal process and the normal function of the intestinal barrier.

Plant-based protein can offer a dairy-free way to meet your daily protein needs, making it a helpful option for people who have difficulty digesting traditional whey or milk-based products. Combining complementary sources, such as pea and brown rice protein, also provides a more balanced range of essential amino acids to support muscle health, tissue maintenance, and overall wellness.

While protein does not “heal the gut” on its own, getting enough high-quality protein is an important part of a balanced diet that supports healthy digestion and intestinal function.

Potato fiber is a plant-based source of dietary fiber that can help support digestive regularity and healthy stool consistency. Depending on how it is processed, potato fiber may also contain resistant starch, a type of carbohydrate that passes through much of the digestive tract without being fully broken down.

Once it reaches the large intestine, resistant starch can be fermented by beneficial gut bacteria and may help support the production of short-chain fatty acids, which play an important role in maintaining a healthy intestinal environment. By supporting regularity and providing nourishment for certain gut microbes, potato fiber can be a useful addition to a balanced, gut-conscious diet.

Individual responses to fiber can vary, especially for people with sensitive digestion, so the amount and specific type of potato fiber used are important considerations.

Slippery elm bark is a botanical ingredient traditionally used to support digestive comfort. When mixed with liquid, it forms a thick, gel-like substance called mucilage, which may help create a soothing coating along the digestive tract.

Because of this naturally soothing texture, slippery elm bark is often included in formulas designed for people with sensitive digestion. It may help provide gentle digestive support and promote a more comfortable gastrointestinal environment.

While slippery elm bark has a long history of traditional use, research on its specific digestive benefits is still limited. It is best viewed as a supportive ingredient rather than a treatment for digestive conditions.

L-glutamine is an amino acid that plays an important role in supporting the cells of the digestive tract. The cells lining the intestines use glutamine as a source of fuel, helping support normal tissue maintenance, cell renewal, and intestinal barrier function.

Because the intestinal lining naturally experiences rapid cell turnover, an adequate supply of amino acids is important for maintaining healthy digestive tissues. L-glutamine is often included in gut-focused formulas to provide nutritional support for these cells and promote overall digestive wellness.

Although L-glutamine supports normal intestinal function, it should not be described as healing the gut or treating digestive conditions. Its benefits can also depend on the amount used, the individual, and their overall diet.
