Consider the following statements in respect of probiotics :
1. Probiotics are made of both bacteria and yeast.
2. The organisms in probiotics are found in foods we ingest but they do not naturally occur in our gut.
3. Probiotics help in the digestion of milk sugars.

Which of the statements given above is/are correct ?

Correct Option: 1 and 3

Probiotics can comprise beneficial bacteria (such as Lactobacillus) as well as yeasts (such as Saccharomyces boulardii). Furthermore, certain probiotics aid in the breakdown of lactose (milk sugar). Statement 2 is incorrect because probiotic organisms are naturally present in the human gut microbiome and are also ingested via fermented foods.
