PureHMO® Tri-Prebiotic for Constipation - HMO, GOS, Inulin FOS

Gut Bacteria Are Part of Your Body: More than 8000 strains of bacteria live in the human gut weighing 2-3 pounds. They help digest food that your digestive system cannot process and produce essential nutrients for your body, such as Vitamin B and Vitamin K. 

Improve Your Gut Functions: Like humans, probiotics also have their favorite foods. The combination of three best prebiotics at 4.4 g per serving: HMO, Galacto-oligosaccharide(GOS), and Inulin Fructo-oligosaccharide (FOS), feed different strains of probiotics in the gut and help increase the diversity of gut microbiota.

Best For Chronic Constipation: A higher diversity of gut microbiota means your gut is more resilient and can help digest food more efficiently, which helps reduce bloating, inflammation, constipation, and irritable bowel syndrome (IBS).


Full Spectrum Prebiotics

Feed more than 50 strains of good bacteria in the gut.

Regain Regularity

4000mg prebiotic fiber to help you relieve constipation and regain regularity.

Stronger Gut and Immune System

Feed the probiotics in the gut to build a tight, strong gut barrier so pathogens and viruses do not penetrate the lining.

Aid Digestion

Aid food digestion, boost biodiversity and the richness of the gut and produce more vital nutrients.

Prevent Pathogen Adhesion

"Natural prebiotics contribute to human health by functioning as anti-adhesives preventing pathogen adhesion, stimulate immune maturation and gut barrier function, and serve as fermentable substrates for gut bacteria. Examples of such beneficial carbohydrates include the human milk oligosaccharides (HMOs), galacto-oligosaccharides (GOS) and fructo-oligosaccharides (FOS)."

Yes, the prebiotics are stable in hot drinks. Probiotics can be killed by hot drinks, but prebiotics will not. Prebiotics are the food for probiotics and will not be deactivated by heat.

PureHMO® Super Prebiotic only contains the human milk oligosaccharide 2'-FL whereas PureHMO® Tri-Prebiotic contains three prebiotics: HMO, GOS, and FOS. PureHMO® Tri-Prebiotic is specially designed to increase the biodiversity of your gut microbiota.

HMO's important for FUT2 non-secretor

I started using this HMO due to my FUT2 non-secretor status. It is important to use to encourage the growth of Bifidobacterium which needs the oligosaccharide to flourish. Super easy to use, I just put one scoop into my morning coffee and know that my gut is being supported in an important way.

My wife has had a problem with constipation fro over 10 years, really her whole life. She was having a movement every 5 or 6 days and usually needed help with enemas, and herbs to make it happen. We tried everything and me being a “doctor” I was frustrated. Pure HMO’s did so much for many of my patients and also myself I started her on one and eventually 2 scoops a day. After she finished the first can of Pure HMO she felt there was some change and wanted to continue with another can of product ( I am saying can I guess it is a container). While waiting for that to arrive I had some Tri prebiotic powder on hand and she started taking that, finishing the container in about a month. Dramatic changes to her bowel activity. Suddenly lots of gas which she never had in the past, rumbling in the colon and after a few days she started getting daily bowel movements. This has continued for several months now, the first time in over 10 years. Honestly, it is a miracle and I do not use that term lightly. It has transformed her entire life, she is happier, exercising more and of course it is because she is feeling great. Imagine how it would feel to start having regular bowel movements after being severely constipated for more than 10 years. I cannot imaging that, but I am thankful beyond belief for this tri-prebiotic powder formula. It was the real key to unlocking her problem. I think for a certain patient, who also is constipated the extra products with the HMO’s are the ticket. For me, I do better with the Pure HMO formula and recently I am using the HMO super formula an seeing consistent improvement, but the Tri-prebiotic formula has an important place in patient care. I would just suggest that you need to find your correct product, these HMO’s have the power to really make a big difference in your life. Notice the big K on th e top of the product! That mean this is Kathy’s HMO formula… 😉


Ordering and delivery were smooth. Just started use, but looking forward to benefit

Smooth Sailing! It works!

I'll be brief. This product does work as advertised and that is a lot to say for me as many products for me just work a little or work only for a short time then quit working. Not his one! It has been effective and consistent! Thank you!
