Probiotics are live microorganisms that can provide health benefits when people consume them. Typically they are available in yogurt form or specially formulated beverages and dietary supplements. They’re also available in fermented foods like kefir, tempeh, kombucha, miso, kimchi, and sauerkraut.

Probiotics can manipulate the gut microbiome. The gut microbiome refers to the accumulation and activity of microorganisms, including bacteria, that reside in the gastrointestinal (GI) tract.

Dietary habits can affect the gut microbiome in ways that are beneficial or detrimental to overall health. Humans can add beneficial bacteria, such as lactobacilli or Bifidobacteriumto their gut microbiome through the use of probiotic supplements or formulated foods.

The Food and Beverage Administration (FDA) does not regulate probiotics and treats them like other dietary supplements. However, it generally does consider them safe.

In addition, the FDA contains many microorganisms in the Generally recognized as safe (GRAS) list, such as the lactic acid-producing strains of probiotics commonly used in yogurt, Lactobacillus bulgaricus and Streptococcus thermophilus.

The relationship between probiotics and weight loss is complex and a subject of ongoing research.

A 2021 scientific review of data suggests that taking probiotics in combination with other healthy lifestyle choices, such as B. regular physical activity, over 12 weeks could lead to weight loss.

Another review examined the relationship between obesity and the gut microbiome. People with a higher body mass index (BMI) may have less diversity in their gut microbiome. The review suggests that probiotic consumption may alter the gut microbiome in ways that promote weight loss in people with high BMI by regulating appetite, metabolism, and energy expenditure.

Similar to other supplements, Probiotics are not subject to the same regulations as drugs or foods. This lack of regulation applies to dietary supplements.

It is therefore not always possible to ensure that the probiotic contains the bacterial strains and quantities that a product is allowed to claim.

In addition, many bacterial populations in a probiotic supplement can change over time due to storage conditions or temperature changes.

A 2015 study reports very rare cases of adverse bacteria-host interactions or other side effects of probiotics, usually in immunocompromised or otherwise critically ill people. The researchers note that taking supplements always carries some risk, and that the safety of probiotics needs further study.

Foods that contain probiotics, like yogurt, are regulated by the FDA. They may not contain probiotics in as high amounts as supplements, but can generally be a safer option for people concerned about risks.

Probiotics are not a substitute for conventional medicine. Probiotics should not be taken by people who are immunocompromised or otherwise seriously ill. If you are pregnant or breastfeeding, seek medical advice before use. Probiotics cannot treat or cure any disease or condition.

When looking for a probiotic, a person can make a few considerations.


Probiotic measurements are Colony Forming Units (CFUs) that estimate the number of viable cells in a given sample under controlled conditions.

The current regulation only requires a manufacturer to declare the total weight of microbes, living or dead, which does not correlate to the actual dose a person is allowed to ingest.

When choosing a supplement that Office of Dietary Supplements (ODS) recommends looking for a supplement that reports the total CFU at the end of the product’s shelf life.


Many probiotic supplements have 1-10 billion CFU, and some have over 50 billion. There is no defined upper consumption limit, but there is also currently no evidence that higher CFU counts have better health effects.

People should also consider the types and quantities of the different strains. However, these do not necessarily indicate safer or higher quality products.

While capsules and powders are the most common probiotic supplements, probiotics are also found in yogurts, fermented milk drinks, and even flavored drinks. A person’s gut microbiome also gradually adapts to dietary changes different diets represent different changes.

Probiotics alone are not likely to support weight loss and should be taken in combination with proven weight loss methods, such as: B. reducing energy intake and increasing physical activity.

Probiotics for weight loss are generally safe and can complement a person’s diet and exercise program. Individuals should try different options to find what works best for them.

Anyone with concerns about the safety of taking probiotics should speak to a doctor for guidance.
