Most probiotic labels tell you how many bacteria are in the bottle — but not whether those bacteria have actually been studied for mood, anxiety, memory, or cognitive health.

In this episode, Rosabel breaks down the science behind probiotic supplements and explains why the CFU number on the front of the label is often the least important thing to look at. You'll learn which specific probiotic strains have been studied for anxiety, depression, mild cognitive impairment, and brain health, what the research actually shows, and why many probiotics never survive long enough to reach your gut.

Topics covered in this episode:

• Why probiotic labels are so confusing
• What CFU numbers actually mean
• The probiotic strains with clinical research for mood and anxiety
• The strain with some of the strongest evidence for mild cognitive impairment
• What studies on Alzheimer's disease have found so far
• Why most probiotics don't survive stomach acid
• A simple 3-step checklist to help you choose a probiotic more confidently

Whether you're shopping for a probiotic, supporting cognitive health, or simply trying to understand the gut-brain connection, this episode will help you separate evidence-based information from marketing claims.
