Supplement designed to support healthy digestion and colon health. Rich in short-chain fatty acids and fiber.


Supplement designed to support healthy digestion and colon health. Rich in short-chain fatty acids and fiber.

To promote a healthy digestive system, Dr. Peter D'Adamo, author of Eat Right 4 Your Type blended two synergistic dietary nutrients, Butyric Acid and Caprylic Acid, with Larch Arabinogalactan to create Intrinsa. These ingredients may provide the following benefits:

  • Butyric acid - This short-chain fatty acid supports health of the lining of the small and large intestines, and serves the natural processes of aerobic energy metabolism. Butyric acid is a normal byproduct of the fermentation of dietary fiber by the gut bacteria, and is one of the main reasons why a high-fiber diet is so healthy.
  • Caprylic acid - This medium-chain fatty acid is absorbed from the intestines and carried by blood lipids.
  • Larch Arabinogalactan - This soluble fiber ingredient can be converted by intestinal bacteria into other short chain fatty acids that also have beneficial effects on the digestive tract.

Intrinsa is suitable for all blood types and may help to alleviate occasional digestive discomforts and supports healthy bowel function.

    After adding Intrinsa to my daily supplements I've noticed a great improvement in how my gut is responding to my food choices.

    those of us who come to rely heavily on Intrinsic for daily well being are seriously inconvenienced when it is out of stock.

    This has really helped to keep me regular. I'm so happy I discovered this product.

  • Happy Tummy

    Posted by Daisy on Mar 7th, 2020

    I notice a big difference when I’m out of Intrinsa-my digestive system is not happy. I include it in my regular regimen to keep my digestive system efficient and avoid bloating, constipation among other stomach disorders. Inspite of the funky smell, I recommend it as it makes a tummy happy.

  • Intrinsa works

    Healthy bowel movements at last!

  • Keeps digestive tract running smoothly.

    Intrinsa along with ARA 6 does an excellent job of smoothing out the operation of the digestive tract. I'm sure it optimizes the extraction of nutrients from beneficial foods.

  • Good gut health

    Posted by T. Dan Tolleson on Dec 1st, 2017

    With Intrinsa, ARA 6, Basic O, Hunter Formula, and the Hunter diet, bowel movements are healthy: solid, brown, and frequent (daily). With the digestive tract working in a healthy manner, I can get things done and exercise my way back to unusual health for someone above 60 years of age.

    I struggle a bit with gut health, and feel adding this to my regime makes a big difference. Even one a day seems to help for maintenance.

  • Intrinsa for the gut

    Posted by Linda on Mar 8th, 2016

    I have been taking 1 twice a day with magnesium, and feel it has helped my gut health.

  • Great supplement!

    Posted by Ella on Dec 9th, 2015

    This supplement really tunes up your GI tract. In combination with probiotics, it has decreased my GERD significantly. Elimination is more regular. Great addition to my daily routine.

  • Intrinsa is fantastic!

    This has been one of my favorite supplements so far. Near instant positive changes for this Type O and my AB husband!
