Probiotics For Healthy Weight Loss: 7 Science-Backed Options

Every capsule of mindbodygreen's probiotic+ packs four bacterial strains that have been scientifically studied for gut health: B. lactis Bi-07 eases bloating and promotes comfort, B. lactis HN019 supports digestion and regularity while easing gas, and L. acidophilus NCFM encourages healthy bowel movements. The standout strain for weight loss is the 10 billion CFUs of B. lactis B420, which has been shown in clinical trials to support the gut barrier and encourage healthy weight through reductions in caloric intake, abdominal fat mass, and waist circumference.*

Like all mindbodygreen supplements, this one has been rigorously tested for purity and potency and is free of binders, preservatives, or any artificial colors or flavors. Its shelf-stable bacteria are packaged in a recyclable glass bottle (no refrigeration needed).

Reviewers note that taking probiotic+ has made a significant difference in their gut health and comfort—often moreso than any other probiotic they've tried. "My stomach bloat was gone after consistently taking this for two weeks," writes one customer. Another says, "I’ve tried a handful of probiotics, this one actually makes a difference, helping with regularity."*

This probiotic contains a single bacterial strain (B. lactis B420), but it's fortified with two botanicals that optimize metabolic rate: organic hibiscus flower extract and organic green coffee bean extract. Both ingredients have thermogenic properties that can support weight loss, though those who are sensitive to caffeine might find them a bit over-stimulating. The additional prebiotics from Jerusalem artichoke feed the beneficial bacteria and make this one of the best probiotics for women looking for weight loss support.*

This probiotic is more geared towards general gut health and comfort, and it contains strains that have been studied for their ability to promote regular bowel movements and support overall microbial health and diversity (Lactobacillus gasseri KS-13, Bifidobacterium longum MM-2, and Bifidobacterium bifidum G9-1). Some of these strains have also been shown to support immunity in animal studies. Users note more energy and digestive comfort since they started taking FloraMend, and it's a solid pick for women and men looking to tend to their gut microbiome. The downside is that it's a probiotic blend, meaning the company doesn't disclose exactly how many CFUs of each strain are in each product.*

This probiotic contains a blend of 19 probiotic strains to support gut health, plus prebiotics and aloe vera to further soothe the gut and support gastrointestinal health. Reviewers note that it also has a positive effect on skin health and appearance, likely because of the additional aloe. One red flag, though: The strain information is missing, so there's no way to know if the strains included have strong scientific testing behind them. And at three capsules daily, the serving size might be a pain for some people.*

When it comes to probiotics, more doesn't always mean better. Bifidobacterium lactis B-420 is a well-studied bacterial strain for weight management, so it makes sense that Bariatric Advantage would lean on it for its single-strain supplement. If you're looking for a simple, clean probiotic without all the bells and whistles, this is a solid option.*

This probiotic contains 10 bacterial strains, including Lactobacillus gasseri BNR17, which has been shown to reduce fat mass and waist circumference in research. However, these strains are part of a proprietary blend so you don't know the exact breakdown of each. Renew Life also adds green coffee bean extract to support weight loss and a plant-sourced prebiotic fiber to further nourish good bacteria. Customers note that the gut-friendly probiotic gives them enhanced energy during the day, in addition to helping them stay more regular.*

This organic probiotic contains six well-research strains (including L. plantarum UALp-05 for gut barrier function and L. gasseri UALg-05 to support weight loss) packaged in vegan pullulan capsules, plus some organic prebiotics for good measure. It's very well-received, with an average 4.5-star rating from 2,331 Amazon customers who note it's helped them with bloating, digestive comfort, and weight management.*
