No Artificial Ingredients
No Preservatives
Supports a healthy immune system by binding to and neutralizing harmful gut agents.
Aids in the gut's ability to repair and absorb nutrients by supporting a healthy inflammatory response.
Offers relief for those unresponsive to traditional treatments like diet and probiotics.
Provides significant improvement in both digestive and non-digestive health issues.
• Ideal for those who do not fully respond to traditional gut treatments like diet, probiotics, and soothing agents.*
• Can be used periodically to quell a gut reaction or occasional flare.*
ISF (Intestinal Support Formula) can lead to and support a healthier intestinal lining, improved nutrient absorption and an overall healthier you.*
Most gut therapies work to balance the bacteria and fungus in your gut. These approaches include dietary changes and probiotic treatments.*
Immunoglobulin supplementation is novel because it supports the immune system instead. This is often the missing piece for those who have not responded fully to other approaches. Immunoglobulins bind to and help neutralize gut irritants.*
After following the compelling preliminary research on immunoglobulins, I began using them in my clinical practice. After using Intestinal Support Formula for several months, I could clearly see that it was an approach that stood out relative to many others. Intestinal Support Formula works well for stubborn gut issues and has a high rate of success. Most patients tolerate ISF very well.
While this is an exciting new development in combating gut issues, it’s very important to always try diet and probiotics first.*

Intestinal Support Formula has been appreciated for its ability to improve bowel movements and regularity, reduce GI issues, and decrease histamine flares. However, the noticeable difference and taste vary among users.

"Bovine immunoglobulins treat gut disorders by reducing leaky gut and inflammatory conditions. It is also known to neutralize bad bacteria and toxins in the gut. This formula tastes great and can be mixed with any cold drink or food. A small scoopful a day is all you need."

"I read that immunogoblin is bad for kidneys so I sent an email asking for their comment on this. Got something saying I would hear in 48 hours, but I never saw anything, and I was looking."

"My son has been struggling with SIBO/SIFO for over a year and have repeatedly been on fluconazole and rifaximin without full recovery. The ISF product has significantly improved his nausea and bloating."

"I think this intestinal Formula helps to calm my digestion. I take it every other day, and I feel like it helps me."
— Sheri M. (5/5)
"I have made sooo many different attempts to repair gut issues over the years, I am hesitant yet hopeful to try something new. Intestinal Support is the best, most powerful, easiest to take and the smoothest and easiest for my gut to receive and assimilate. I have gone weeks in between servings which is a major accomplishment! Thank you Dr Ruscio and team. Hope has been restored !"

"Big help for my gut. I take this in between meals. But I have to mix it in flavor because it has a “fatty” lard like taste afterwards…Hopefully flavor will be different next time"
