Electrolytes
Strong evidence
Minerals that carry an electrical charge in body fluids. Sodium, potassium, chloride and magnesium are the ones that matter most for everyday hydration.
- Form
- Sodium, potassium and magnesium salts
Why it's included
On heavy-sweat South African days, plain water replaces fluid but not the sodium lost with it. FLOW is built for those days rather than for every day.
What the research says
Consistent findings across multiple well-designed human studies.
- Sodium is the primary electrolyte lost in sweat, and replacement supports fluid retention during prolonged heat or exercise.
- Rehydration guidance for endurance and heat exposure consistently includes sodium alongside fluid.
What research does not establish
- That electrolyte supplements benefit sedentary people with normal diets.
- That electrolytes detoxify the body or boost metabolism.
- That any consumer electrolyte product matches medical rehydration therapy.
Safety considerations
- If you are on a sodium-restricted diet or have high blood pressure or kidney disease, speak to your doctor first.
- Not a treatment for dehydration caused by illness — seek medical care instead.
