Diarrhea - Humarian

No matter the age, diarrhea is a common issue. Diarrhea can be a result of poor diet, illness, poor balance of bacteria in the gut, and more. It is also one of the most common side effects of antibiotic usage. Antibiotics do not distinguish good from bad bacteria. While they do a very important job of killing off harmful infections, they also disrupt the balance of bacteria in your gut by killing off some good bacteria. This opens the door for other harmful bacteria to flourish, like Clostridium difficile (commonly known as C. diff), a common cause of diarrhea.

Thankfully, probiotics can help. They can reduce the effects of diarrhea by promoting better digestion, improving regulation of bowel functions, and reducing the side effects of antibiotics. Studies have shown that strains like L. acidophilus and P. acidiactici can alleviate acute diarrhea in both children and adults. Other strains are effective in dealing with antibiotic-associated diarrhea, such as L. casei, which has been shown to help prevent C. difficile diarrhea in adults.

Probonix helps to promote better digestion and contains several strains that have been shown to help with diarrhea.

Love this probiotic! My daughter was suffering from the after-effects of a GI infection and after two weeks still had problems processing lactose (i.e. had frequent green poop). After a single dose of this probiotic her poop was normal colored again. After two doses her diarrhea was gone! She was EBF at the time but the impact of this probiotic was undeniable.


I use this for my kids, especially after a round of antibiotics. This probiotic produces a noticeable difference in their bowel movements; solid and regular whereas previously they would get diarrhea or loose bowel movements. This product solved the problem 100%.


My 7-month-old daughter had diarrhea for 10 days. I gave this to her, and within 2 days her stools had completely normalized. What a relief to me, and to her. Also, I called Humarian Labs with a question and they returned my call within a few hours, providing a very scientific and complete explanation. I feel confident that this product is backed by research. I am so thankful for this product and this company.

Antibiotics and Probiotics

by Ryan Bentley, MD, PhD, DC

Antibiotics are some of the most useful medications in use today. They combat a wide range of health issues and treat life-threatening disorders. They are perceived to be effective while having minimal risks. This combination of factors explains why they are also among the most widely prescribed medications despite the fact that they come with their own set of risks and side effects.
