Probiotic Myths

Busting common misconceptions like “all probiotics are the same.”

What Exactly Are Probiotics?

Probiotics are live microorganisms, mostly bacteria and some yeasts, that naturally live in your body — mainly in the gut, but also in the mouth, skin, and even the urinary tract. The World Health Organization (WHO) defines probiotics as “live microorganisms which, when administered in adequate amounts, confer a health benefit on the host.”

Your gut alone houses over 100 trillion microbes. Probiotics are the beneficial ones, helping to:

Maintain Balance

Keep harmful bacteria in check by creating a protective barrier and competing for resources.

Support Digestion

Support digestion and break down foods your body can’t digest on its own.

Produce Vitamins

Generate essential vitamins like B12, K, and folate that your body needs for optimal function.

Boost Immunity

Train your immune system to recognize threats and fight off infections more effectively.

The Balance Matters

When your gut microbiome is in balance, you feel energetic, digest food well, and have stronger immunity.

When it's off balance, problems like bloating, frequent illness, low energy, or skin flare-ups may appear.

By training your immune cells and producing antimicrobial compounds, probiotics strengthen your natural defense.

Stress or Anxiety

Emerging research shows probiotics influence the gut-brain axis, easing stress and improving mood.

Why Prebiotics Are Just as Important

Probiotics need fuel to survive — and that’s where prebiotics come in. Prebiotics are fibers found in certain foods that your body can’t digest, but your gut bacteria can.
