Sodium & blood volume
How much sodium do people with POTS typically use?
Many POTS protocols involve higher sodium intake to support blood volume. The numbers vary — and they must be personalised with a clinician.

Why more salt?
Higher sodium + fluids can support blood volume (for some people).
Sodium helps your kidneys hold onto more water. With more circulating blood volume, your body may cope better when you stand up, which can reduce dizziness and “crash” episodes for some people.
Typical elements of a plan
- Baseline sodium target (spread across the day)
- Electrolyte drinks with clear sodium content
- Extra fluids with meals and before standing
- Adjustments for heat, travel, exercise, and flare days
It’s not just about hitting a number — it’s timing, symptoms, and what you can actually keep down.
Safety matters
- Too much sodium can raise blood pressure or worsen swelling.
- Kidney and heart conditions may limit what’s safe.
- Some medications (including BP meds and diuretics) can interact with sodium changes.
Don’t copy someone else’s sodium routine 1:1. Use clinician guidance and monitor how you respond.
Want a simple way to execute this?
Build a routine around “anchor moments” (wake-up, mid-morning, lunch, mid-afternoon, evening) so your sodium and fluid intake is spread out — not slammed all at once.
Still: personalise with your clinician.
