Lately, I’ve had several clients and readers ask me about Bioma, a probiotic supplement that’s being heavily marketed online. The company claims it helps you lose weight, reduce cravings, balance your gut, fix your metabolism, and even improve mood, simply by “resetting” your gut bacteria. Wow all that? Sounds too good to be true right?

As a Registered Dietitian and specialist in eating disorders and intuitive eating, I want to speak clearly: these claims are exaggerated, often misleading, and potentially harmful to your relationship with food and your body.

Let’s break down some of Bioma’s biggest promises, and compare them to actual scientific evidence.

Claim #1: “Lose Up to 18 Pounds” by Balancing Gut Bacteria

There is some early evidence that specific probiotic strains, like Bifidobacterium breve B-3 and B. lactis IDCC 4301, can modestly reduce fat mass. The average fat loss? About 0.5–1% body fat, or around 1–3 pounds over 12 weeks.

Bioma’s “18-pound weight loss” claim often comes from a customer review featured in their ads, not from a clinical study. This is an example of testimonial marketing, where a dramatic personal story is presented as typical or guaranteed results.

Testimonials can be misleading as they are anecdotal and may not apply to everyone.  There is also no control for diet, exercise of other lifestyle changes.  In addition some effects may be due to the placebo effect.  Companies always highlight the best results and ignore many who do not see a change.  Yes, testimonials are powerful marketing tools, but not scientific proof.

Claim #2: “Reduce Cravings and Suppress Appetite”

Some probiotic strains may influence appetite hormones, but the research is limited and inconsistent.Using supplements to “control” cravings can sometimes intensify unhealthy eating behaviors, especially in those recovering from disordered eating.

 Claim #3: “Fix Your Metabolism”

Metabolism is complex and influenced by many factors beyond gut bacteria. No probiotic can “reset” your metabolism.

 Claim #4: “Improve Mood, Focus, and Energy”

Gut health affects mental health, but Bioma doesn’t provide the strains or research backing these mood claims. Such messaging promotes diet culture myths, increases anxiety about food and body, and can trigger or worsen disordered eating.

What actually supports gut health is a balanced, fiber-rich diet, regular meals and snacks, managing stress and prioritizing sleep and lastly honoring your hunger and fullness cues.

Final thoughts are, if it sounds too good to be true, it probably is. Weight loss is complex, and probiotics are not magic pills.  You deserve care based on science and compassion, not hype and quick fixes.  Do you need supplements at all, read our blog on supplements.
