The Science Behind the Calculator
Weight-Based Formula
Your body weight determines baseline water needs — approximately half your weight (lbs) in ounces daily.
Activity Multiplier
Physical activity increases fluid loss through sweat. Higher intensity = more electrolyte replacement needed.
SGLT1 Formulation Rationale
BIOS uses sodium and glucose as part of a formula informed by established sodium-glucose cotransport physiology; finished-product outcomes require product-specific validation.
