Who Should Avoid Probiotics, and What That Means for Sodatide

Most healthy adults can try a probiotic with little risk. A few groups should skip them or get a doctor's go-ahead first.

The NIH puts it simply: probiotics are unlikely to cause harm in healthy people, but they may harm people who are severely ill or immunocompromised (NIH ODS, Probiotics (health professional)). Live bacteria are the point of a probiotic. In a body that cannot keep them in the gut, they can end up where they do not belong.

Sodatide counts here because its 36 mg blend holds three species: Bifidobacterium infantis, Clostridium butyricum and Akkermansia muciniphila. The label does not say whether they are live or pasteurized, so treat them as live.

Yes, rarely. The risk of harm is greater in people with severe illness or a compromised immune system (NCCIH, Probiotics).

• Cancer treatment such as chemotherapy
• Drugs taken after an organ transplant
• High-dose steroids
• A hospital stay for a serious illness
• A central line, the IV tube that sits in a large vein

There is a second concern. Some probiotic products have been found to hold microbes not listed on the label (NCCIH, Probiotics). A healthy gut may shrug that off. A weak immune system may not.

Not always, but each one deserves a question to your doctor first.

Picture a 37-year-old with IBS who bloats on fiber. The 211 mg of chicory root inulin in a capsule is small, but small is not zero. Start only with your doctor's okay and note how week one feels. See our post on inulin and bloating.

NIH Office of Dietary Supplements, current page.Label weight "has no relationship with the number of viable microorganisms in the product"; many products contain 1 to 10 billion CFU per dose. Probiotics are "unlikely to cause harm in healthy people" but may harm people who are severely ill or immunocompromised; one review found a 0.82 cm waist reduction and no effect on body weight or BMI.

"Some probiotic products have been reported to contain microorganisms other than those listed on the label." Consult a health care provider first.
