A brief overview of the 7 best probiotics for weight loss in 2022

Probiotics are live microorganisms that can provide health benefits when people consume them. Typically, they come in the form of yogurt or specially formulated drinks and supplements. They are also available in fermented foods such as kefir, tempeh, kombucha, miso, kimchi, and sauerkraut.

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

Food choices can influence the gut microbiome in ways that help or hurt overall health. People can add beneficial bacteria, such as lactobacilli Where bifidobacteriumto their gut microbiome by using probiotic supplements or formulated foods.

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

Additionally, the FDA includes many microorganisms in the Generally recognized as safe (GRAS) listing, such as strains of lactic acid-producing probiotics commonly used in yogurts, Lactobacillus bulgaricus and Streptococcus thermophilus.

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

A 2021 scientist exam evidence suggests that taking probiotics may lead to weight loss over 12 weeks in combination with other healthy lifestyle habits, such as regular physical activity.

Another opinion examined the relationship between obesity and the gut microbiome. Those with a higher body mass index (BMI) may have reduced diversity in their gut microbiome. The review suggests that consuming probiotics may alter the gut microbiome in ways that promote weight loss in people with a 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 supplements.

Therefore, it is not always possible to be sure that the probiotic contains the bacterial strains and amounts that a product is eligible for.

Additionally, many bacteria populations in a probiotic supplement can change over time due to storage conditions or temperature fluctuations.

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

Foods containing probiotics, such as yogurts, 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 the risks.

Probiotics do not replace conventional medicine. Probiotics should not be taken by immunocompromised or seriously ill people. If pregnant or breastfeeding, consult a doctor before use. Probiotics cannot treat or cure any disease or condition.

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


Probiotic measurements are colony forming units (CFU) which estimate the number of viable cells in a given sample under controlled conditions.

Current regulations only require a manufacturer to declare the total weight of microbes, alive or dead, which does not correspond to the actual dose a person may consume.

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


Many probiotic supplements have 1 to 10 billion CFU, and some have more than 50 billion. There is no set upper consumption limit, but there is currently no evidence to suggest that high numbers of CFUs have better health effects.

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

Although capsules and powders are the most common probiotic supplements, probiotics are also available in yogurts, fermented milk drinks, and even infused into flavored drinks. An individual’s gut microbiota will also gradually adapt to changes in diet, with different diets make different changes.

Probiotics alone are unlikely to promote weight loss and should be taken in conjunction with proven weight loss methods, such as reducing energy intake and increasing physical activity.

Below we look at some common questions about probiotics for weight loss.

Can probiotics help with weight loss?

Evidence shows a link between probiotics and weight loss when a person uses them along with a balanced diet and exercise program.

A person may need to try different products to find a probiotic supplement that meets their needs.

Is there a recommended probiotic dosage or intake suggestion?

No. There is currently no research suggesting an ideal number of CFUs or preferred methods of consuming probiotics.

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

Anyone concerned about the safety of taking probiotics should consult a doctor for advice.

Experts are constantly studying probiotics to find the most effective bacterial strains and the optimal CFU dosage. They might then be able to confirm the link between the gut microbiome and weight loss.
