The Claim
Some individuals believe that prebiotics can fully substitute probiotics, as both are associated with promoting gut health.
Origin
This myth is often fueled by simplified explanations in health articles and marketing that blur the distinct roles of prebiotics and probiotics.
What Science Says
While prebiotics and probiotics both support gut health, they function differently. Probiotics are live microorganisms, whereas prebiotics are substrates that promote the growth of beneficial bacteria. Studies, including systematic reviews, suggest that their effects are complementary, not interchangeable (Markowiak & Śliżewska, 2017).
Verdict
False
