Electrolytes and hydration for perimenopause
Night sweats, hot flushes and GLP-1 medications all pull fluid and sodium out of you faster than plain water replaces it. Persistent afternoon fatigue, headaches and dizziness on standing are often a hydration problem wearing a hormone costume.
Quick answer
Sodium in the 300 to 1000mg range per serving; token amounts do very little. Options below start around $15.95, sold directly by Shopify merchants.

What to look for
- Sodium in the 300 to 1000mg range per serving; token amounts do very little.
- No or low added sugar unless you are using it around endurance exercise.
- Added magnesium and potassium are useful; a long ingredient list of botanicals usually is not.
If you have high blood pressure or kidney disease, check sodium intake with your clinician before adding an electrolyte product daily.
Electrolytes & hydration FAQs
Do I need electrolytes if I'm not an athlete?
Most women do not need them daily. They earn their place during heavy night sweats, in hot weather, during GLP-1 side effects, or when you notice headaches and lightheadedness despite drinking plenty of water.
How much water should I drink in perimenopause?
Around 2 to 2.5 litres a day for most women, more with heat, exercise or night sweats. Our daily water intake calculator gives a number based on your weight and activity.
Can electrolytes help with GLP-1 fatigue?
Often yes. Reduced appetite means reduced sodium and fluid intake, and the resulting fatigue is frequently mistaken for the medication itself.
Are sugar-free versions better?
For everyday use, yes. Sugar in an electrolyte drink is there for endurance fuelling, which most perimenopause use cases do not need.
