Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculate effective dosing ranges for prebiotic fiber (inulin, FOS, GOS) and probiotic CFU counts based on target health outcomes and individual tolerance

Each component has a specific meaning:

  • Target health outcomes — The target health outcomes recorded for the scenario being assessed.
  • Individual tolerance — The individual tolerance recorded for the scenario being assessed.

Note: Interpret the prebiotic/probiotic dose result against the thresholds and context described above.

How to Use

Enter the target health outcomes, individual tolerance for the scenario you are assessing. Calculate effective dosing ranges for prebiotic fiber (inulin, FOS, GOS) and probiotic CFU counts based on target health outcomes and individual tolerance. Use the prebiotic/probiotic dose result to inform your calculation.
