When You’re Doing Everything Right — and Still Feel Dizzy
If you’ve tried electrolyte drinks and still feel lightheaded, fatigued, or unstable, you’re not doing anything wrong. This is a common frustration in the POTS community. Many people assume all electrolyte supplements work the same — but they don’t. Understanding why some fall short can save you time, money, and discouragement.
Not All Electrolytes Are Created Equal
Electrolytes are often marketed like sports drinks, not medical support tools. Many products focus on taste, branding, or low calories rather than therapeutic dosing. In this post, we’ll explain why some supplements don’t improve POTS symptoms, what your body actually needs, and how to spot products that are unlikely to help.
Sodium Is the Star Player for POTS
For most people with POTS, sodium matters more than any other electrolyte. Increasing sodium helps expand blood volume, which can reduce dizziness and improve circulation when upright. Research-based POTS management often recommends up to 8–12 grams of extra sodium chloride per day in certain patients. That’s far more than most people realize.
The Problem With “Flavoring-Level” Sodium
Many electrolyte drinks contain only 50–500 mg of sodium chloride per serving. That amount may enhance flavor, but it won’t meaningfully impact blood volume for someone with POTS. To put it simply, a supplement with very low sodium isn’t broken — it’s just not designed for this condition (EVEN IF IT SAYS POTS ELECTROLYTES). That’s why symptoms often don’t change.
Why More Isn’t Always Better — But Less Often Isn’t Enough
Sodium needs vary based on body size, activity level, climate, and symptom severity. Some people do well with moderate increases, while others need much more support. The issue isn’t that electrolyte supplements never work — it’s that many don’t meet the threshold required to help. POTS management is about dosing, not just presence.
What to Look for in an Electrolyte Supplement
Effective options tend to clearly list sodium content and provide hundreds to thousands of milligrams per serving. They’re designed to support hydration, not just taste. Labels matter more than marketing claims. If sodium content isn’t easy to find, that’s a red flag.
The most common supplement I recommend to my patients is straight 1000mg sodium chloride tablets. They are super cheap (365 1g tabs for less than $15 on Amazon). These allow you to easily dose yourself starting at 1-2 g per day extra and moving up from there as needed/ tolerated.
When Electrolytes Still Aren’t Enough
Even with proper sodium intake, symptoms can persist if other factors are at play. Deconditioning, MCAS, nutrient deficiencies, heat, or pain can all blunt the benefits. Electrolytes are foundational — not a cure-all. If they help a little but not enough, that’s valuable information, not failure.
You’re Not Resistant — You’re Under-Dosed
When supplements don’t work, many people blame their body. In reality, the product may simply be too weak for what POTS requires. Once you understand dosing, things often make much more sense.
