Who Should Avoid or Consult First

  • Individuals with severe underlying medical conditions, especially those hospitalized or critically ill
  • Those with central venous catheters (due to a rare risk of infection)
  • People with short bowel syndrome or pancreatitis
  • Infants and very young children (unless specifically formulated for them and under medical guidance)
  • Pregnant or breastfeeding women should consult their doctor first

Common Side Effects

  • Bloating — reported in some users, especially when first starting
  • Gas — a common initial side effect
  • Mild stomach discomfort or cramps
  • Diarrhea or constipation (less common, usually temporary)

Interactions to Watch For

Antibiotics

Antibiotics can kill beneficial bacteria, so it's best to take RenewLife Ultimate Flora at least 2-3 hours apart from antibiotic doses to maximize its effectiveness.

Immunosuppressant medications (e.g., cyclosporine, corticosteroids)

In rare cases, probiotics could potentially increase the risk of infection in severely immunocompromised individuals, so consult a doctor before use.
