Probiotics can boost your immune system against all infections
Mostly trueThe Claim
Some people believe that taking probiotics can universally enhance immune function and protect against all types of infections. This misconception may arise from the understanding that gut health is linked to immune health.
Origin
This myth can be traced back to promotional claims that highlight the immune-supporting properties of probiotics without specifying the context or limitations.
What Science Says
Research indicates that while certain probiotic strains can enhance immune response, particularly in preventing respiratory infections, they do not guarantee protection against all infections. A review found that probiotics may reduce the incidence of upper respiratory tract infections in healthy individuals, but the effect is strain-dependent and not universally applicable.
