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.

HMO & GOS as Prebiotics

"Human milk oligosaccharides (HMO) are believed to have a range of biological activities beyond providing nutrition to the infant..... GOS as similar to breast milk oligosaccharides, they encourage a gut bacteria population that promotes health and reduces the incidence of intestinal infections."

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.

About thirty years. My whole insides are a burning fire all the time.
I also have fm and cf - 83 years old. Most DRS don’t seem to care.

Also on a limited budget. I hope I can at least gat the $6.00 savings.
Thanks for your concern.

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.
