Intestinal Support Formula (ISF) binds to and deactivates gut irritants (toxins and microbes) — reducing the immune & inflammatory response — leading to a healthier intestinal lining, improved nutrient absorption and a healthier you.

What is Intestinal Support Formula?

A blend of immunoglobulins that act to bind and neutralize toxins in the gut. These are naturally occurring in humans. You have many types of immunoglobulins in your gut right now.

These immunoglobulins are free of casein, whey, lactose, soy, gluten, and dye.

Preliminary clinical research has shown this to be true – this is not speculation

To date, nine quality trials, in humans, have shown improvement with Intestinal Support Formula (ISF). 1, 2, 3, 4, 5, 6, 7, 8, 9

The research has even shown that, 10 in those who have not fully responded to other gut treatments ISF can make the difference. ISF has been shown to help patients who did not respond to treatments like diet, probiotics, antimicrobials and soothing agents.

This is worth repeating. In a study by Weinstock: 11

  • Patients were diagnosed with either SIBO, IBS or both
  • Then offered a few different treatments
  • In those who did not respond to any treatment, they were given ISF
  • A 75% response rate was noted!

More Science

The evidence supporting ISF also includes one randomized, placebo-controlled trial 12 and one large survey of 595 patients wherein 67% reported benefit from ISF. 13

In a double-blind, randomized, placebo-controlled study, Intestinal Support Formula caused a significant improvement in: 14 abdominal pain, flatulence, urgency, loose stools, bloating or any symptom.
