Understanding Fatigue Worsening After Probiotic Intake

Explore the connection between probiotics and increased fatigue, potentially linked to conditions like SIBO and D-lactic acidosis. Discover how these supplements may exacerbate symptoms and learn about the importance of consulting a healthcare professional for personalized advice.


  • Fatigue worse after taking probiotics

    Anyone else have this too? I can’t seem to figure it out. My gut issues led to chronic fatigue, but it’s worse when I take probiotics even a small amount like 1 billion.

  • Experiencing fatigue that worsens after taking probiotics can be perplexing, but it might be linked to certain conditions like Small Intestinal Bacterial Overgrowth (SIBO) and D-lactic acidosis. Research suggests that in some individuals, especially those with underlying conditions like SIBO, the use of probiotics might exacerbate symptoms such as brain fog, gas, bloating, and fatigue1. This happens due to an overgrowth of bacteria or an imbalance in the gut microbiome, leading to the production of D-lactic acid, which can cause metabolic complications1.

    If probiotics seem to worsen your fatigue or other symptoms, it might be beneficial to consult with a healthcare professional who can assess your condition more thoroughly. They might suggest modifications to your supplement regimen or investigate potential underlying conditions that could be contributing to the reaction you're experiencing.
