The Claim
Many believe that consuming prebiotics will result in immediate improvements in gut health, leading to better digestion and overall well-being within a short time frame.
Origin
This myth is often propagated by marketing campaigns and anecdotal reports emphasizing quick results from dietary supplements.
What Science Says
Research indicates that while prebiotics can beneficially modify gut microbiota, the effects are gradual and depend on factors like diet, existing gut health, and individual microbiome composition. A review of randomized controlled trials (RCTs) suggests that noticeable changes can take several weeks to manifest (Gibson et al., 2017).
