Statements 1 and 3 are correct. Statement 2 is incorrect.

Probiotics comprise beneficial live microorganisms, predominantly bacteria (like Lactobacillus) and sometimes yeast (like Saccharomyces boulardii). Crucially, these friendly microbes do naturally occur in the human gut biome, rendering Statement 2 false. They are widely known to alleviate lactose intolerance by breaking down milk sugars (Statement 3).
