3 Key Amino Acids for Gut & Digestive Health

3 Key Amino Acids for Gut & Digestive Health

3 Key Amino Acids for Gut & Digestive Health


It makes sense that what we ingest can directly impact the long-term health of our gut and digestion system. A healthy gut has a protective mucosal lining which prevents toxins being absorbed into the bloodstream. Our gut lining can be damaged through bacterial imbalance, stress, lack of sleep, the cumulative impact of a nutrient poor diet or triggered  by certain health conditions such as Celiac Disease, Irritable Bowel Syndrome (IBS) or Leaky Gut Syndrome.


Similar to how collagen strengthens and tightens your skin, it has the same effect for the digestive system as it is a major constituent of the connective tissue lining of the gut and intestines. The digestive tract is made up of the same amino acids that are abundant in collagen thus these crucial amino acids can help stimulate cell growth, assisting digestive processes by supporting and repairing intestinal walls.


Amino Acid Assistance

The three key amino acids found in collagen that support gut health and digestion are:

  • Glycine: Improves digestive processes, helping to stimulate the natural production of stomach acid and improving the nutrient absorption.


  • Glutamine: Supports the intestinal lining of the stomach and opening junctions in the connective tissue, plus has been tied to supporting metabolism and helping to curb cravings.


  • Proline: Along with glycine, proline helps synthesize collagen. This amino acid can support wound healing, support digestive health, increase metabolism and fight inflammation in the intestinal tract.


Collagen Sources for Supporting Gut Health


Nutraviva Collagen Hydrolysate and Marine Collagen are highly biocompatible protein sources with high percentages of these important amino acids for gut health: glycine (23%), proline (13%) and glutamine (9.5%). These high levels of key amino acids can also provide a satiating effect further supporting weight management and curbing unhealthy food cravings. Gelatin is another natural food source that has these key amino acids, plus as a long chain protein it is broken down slower in the body and with its gelling properties can coat the stomach soothing digestive issues.

Another great source of collagen cane be found in bone broth. The minerals and amino acids in bone broth are highly bioavailable nutrients, as they come in an easy-to-digest form. It can be difficult for the body to digest proteins or absorb certain minerals. So, even when we consume foods with healthy nutrients, our bodies don’t always absorb all of them and i you suffer from digestive issues this can be particularly so. If you do have digestive issues, bone broth is very easy for the digestive system to digest making it easier to benefit from these key nutrients.


Nutraviva Beef Bone Broth powders contain types I, II and III collagen which assist in the efficacy and bioavailability of the amino acids. Our broth powders are made from all-natural ingredients with no preservatives or artificial flavours added, so you can be sure you are getting the healthiest and best-tasting broth available.


If you prefer to choose non-animal sources for nutritional supplements, or are looking for plant-based options, Vegan Collagen Alternative is a premium protein powder containing a comparable amino acid profile to animal sourced collagen powders. It also contains probiotics and a suite of carefully selected superfoods to support digestive health.
