Why Doctor's Biome is Effective Against C. diff
Doctor’s Biome is uniquely effective in supporting recovery from C. diff and helping inhibit recurrence, especially in cases where antibiotics alone may not be enough. It delivers living, active probiotic strains directly to the gut, where they’re needed most. Its patented delivery system protects beneficial bacteria from stomach acid, allowing them to survive and colonize the intestines. Formulated as a medical food, it’s specifically designed to help restore healthy gut flora, reduce inflammation, and support long-term microbiome balance after the disruption caused by antibiotics and infection.

CUSTOMER REVIEWS
"C-Diff is gone"
Nine months ago I was diagnosed with Crohns Diseease and tested positive for C-Diff. Prior to that I experienced the most horrific gut pain or any pain I ever experienced. Could not eat any food as any intake would increase the pain. As a result I lost over 50 lbs in 7 months and mostly muscle and became very weak. My functional doctor put me on a 90 day program of various supplements.
One of those products was Dr. Biome Medical Food. I am so excited to report after 2 GI tests the C-Diff is gone but more important to me is no pain and I now can consume food and have added 8 pounds to my weight. I am still taking the Medical Food only because thee C-Diff has known to make a return. I believe the Dr. Biome Medical Food saved my sanity. I would definitely recommend anyone with C-Diff to give this a try.
"Chronic C-Diff"
I took this for one month and my chronic c-diff depleted by 2/3's. I can’t wait to get my next round of testing. Nothing else has worked over a four year period, but Dr.s Biome has!

More Than Just an Infection...
Clostridium difficile infection (CDI) is a leading cause of healthcare-associated infections, impacting over 500,000 people in the U.S. each year1. CDI typically develops following antibiotic use, which disrupts the gut microbiota responsible for normal bile acid metabolism2. This disruption enables C. diff spores to germinate and produce toxins, leading to characteristic symptoms such as severe diarrhea and inflammation2. This mechanism of infection contributes to the difficulty in treating CDI and its frequent recurrence.
- C. diff can impact anyone, but most cases of infection occur while you're taking antibiotics or not long after you've finished taking antibiotics.3
- Because C. diff can live outside the body, the bacteria spread easily, especially by those not washing hands or cleaning well.4
- Of those affected, around 30,000 patients die annually due to C. diff infections.1
- Almost half of infections are in people younger than 65, but more than 90 percent of C. diff–related deaths are in people over age 65.5
- C. diff recurs in about 1 in 5 patients.6
