The best electrolytes for POTS are the ones that deliver high sodium per serving at a reasonable cost per gram. POTS patients typically need 3,000–10,000mg of sodium daily (per the 2021 Expert Consensus),[1] which is 2–4x what most electrolyte brands provide in a single serving. That makes sodium content and price per gram of sodium the two numbers that actually matter.
We compared all 17 brands in our comparison table and filtered for the ones relevant to POTS. The short answer: Hydrate Pro ($0.78/g sodium), Redmond Re-Lyte ($0.93/g sodium), and Vitassium ($1.00/g sodium) offer the lowest cost per gram of sodium. LMNT delivers 1,000mg per serving but costs $1.50/g sodium. Full breakdown below.
How Much Sodium Do POTS Patients Actually Need?
General dietary guidelines recommend less than 2,300mg of sodium per day. POTS flips that entirely. The 2021 POTS Expert Consensus Review (Vernino et al.) recommends 3,000–10,000mg of sodium daily, paired with 2–3 liters of fluid.[1]
A 2021 study published in the Journal of the American College of Cardiology (Garland, Raj et al.) found that high dietary sodium intake reduced standing heart rate and orthostatic tachycardia in POTS patients compared with a low-sodium diet.[2] High sodium also increased plasma volume and lowered standing norepinephrine levels.
Here's what that means practically: if your electrolyte brand provides 1,000mg sodium per serving, you need 3–10 servings per day just from supplements (not counting food). If it provides 500mg, double those numbers. If it provides 300mg, you'd need 10–33 servings. At that point, cost per serving stops being the right metric. Cost per gram of sodium is what matters.[5]
Every Electrolyte Brand Compared for POTS
Here are the 10 brands from our comparison that provide 480mg+ sodium per serving, sorted by cost per gram of sodium (lowest first). These are the ones worth considering for POTS-level sodium needs.

Why $/g sodium matters for POTS: A $0.52/serving electrolyte with 300mg sodium costs $1.73 per gram of sodium. A $0.78/serving electrolyte with 1,000mg sodium costs $0.78 per gram. When you need 3,000–10,000mg daily, the cheaper-looking brand can cost 2–4x more for the same amount of sodium.
Which Brands Have Enough Sodium for POTS?
Tier 1: 800–1,000mg sodium (best for POTS). LMNT, Hydrate Pro, and Zerolyte all deliver 1,000mg. SALTT provides 969mg. NormaLyte has 862mg. Redmond Re-Lyte offers 810mg. Santa Cruz Paleo provides 800mg. These brands require only 3–4 servings to reach 3,000mg sodium. That's manageable.
Tier 2: 480–500mg sodium (workable, but more servings needed). Vitassium, Liquid IV Sugar-Free, and Thorne Daily Electrolytes fall here. You'd need 6+ servings daily to reach 3,000mg. Vitassium gets away with it because capsules are fast to take. Liquid IV at 6 servings daily gets expensive ($9.36/day).
Tier 3: Under 400mg sodium (probably not enough for POTS). Nuun Sport (300mg), DripDrop (330mg), and Hydrant (260mg) are designed for general hydration, not POTS-level sodium loading. You'd need 10+ servings daily. These work fine for light activity, but most POTS patients will need something stronger.
Sugar or No Sugar? The ORS Question
Most electrolyte brands are sugar-free. Two notable exceptions: NormaLyte (6.75g sugar from dextrose) and DripDrop (7g sugar). These aren't cutting corners. They're using oral rehydration solution (ORS) formulations where glucose activates sodium-glucose cotransport in the gut, potentially improving sodium and water absorption.[3]
Some POTS patients report that ORS-style electrolytes like NormaLyte work better for blood volume than sugar-free alternatives. Others prefer sugar-free brands because they have MCAS (Mast Cell Activation Syndrome) overlap or simply don't want added sugar multiple times a day. Individualized dietary strategies are important because dysautonomia patients often have overlapping conditions that affect tolerance.[4]
There's no universal right answer here. If sugar-free electrolytes are working for you, stick with them. If you're doing everything right and still symptomatic, an ORS formula might be worth trying. Talk to your doctor.
Does Form Factor Matter for POTS?
Capsules (Vitassium): The only capsule option in our comparison. Popular with POTS patients who experience nausea, since there's no taste, mixing, or drinking large volumes involved. Downside: only 500mg sodium, no magnesium, and minimal potassium (100mg).
Tub/Scoop (Hydrate Pro, Re-Lyte, Santa Cruz Paleo): Cheapest per serving across the board. Great for daily home use. You measure with a scoop and mix into water. Less portable than stick packs, but you're paying 30–50% less per serving for the same sodium.
Stick Packs (LMNT, SALTT, Zerolyte, NormaLyte, Thorne): Pre-measured and portable. Toss one in your bag for appointments, work, or travel. The convenience premium is real: stick packs consistently cost more per serving than tub-format brands with similar sodium content.
Tablets (Nuun): Drop a tablet in water and wait. Only 300mg sodium per tablet, which is too low for most POTS patients as a primary sodium source. Could work as a supplement alongside higher-sodium options.
What Does This Actually Cost Per Day?
POTS is a chronic condition. You're buying electrolytes daily, indefinitely. Here's what a conservative target of 3,000mg sodium per day costs across the top brands (from supplements alone, not counting dietary sodium):
| Brand | Sodium/Serving | Servings for 3,000mg | Daily Cost | Monthly Cost |
|---|---|---|---|---|
| Hydrate Pro | 1,000mg | 3 | $2.34 | $70 |
| Redmond Re-Lyte | 810mg | 3.7 | $2.78 | $83 |
| Vitassium | 500mg | 6 | $3.00 | $90 |
| Zerolyte | 1,000mg | 3 | $3.60 | $108 |
| SALTT | 969mg | 3.1 | $3.63 | $109 |
| Santa Cruz Paleo | 800mg | 3.75 | $3.75 | $113 |
| LMNT | 1,000mg | 3 | $4.50 | $135 |
| NormaLyte | 862mg | 3.5 | $4.66 | $140 |
| Liquid IV (SF) | 500mg | 6 | $9.36 | $281 |
Data verified against manufacturer websites. Prices as of March 2026. See the full 17-brand comparison →
The spread is dramatic. Hydrate Pro costs $70/month. Liquid IV costs $281/month. Both are electrolyte powders. The difference is sodium concentration and packaging format.
The Bottom Line
Here's what the data supports, broken down by what matters most to you:
Best overall value for POTS: Hydrate Pro: 1,000mg sodium, $0.78/serving, $0.78/g sodium, tub format. Lowest cost per gram of sodium in our entire comparison. Or Redmond Re-Lyte: 810mg sodium, $0.75/serving, $0.93/g sodium, plus the highest potassium (400mg) of any tub brand.
Best stick pack for POTS: SALTT: 969mg sodium, 415mg potassium, and 178mg magnesium (by far the most of any brand). $1.17/serving. If you want a single packet that covers sodium, potassium, and magnesium, SALTT is the most complete option.
Best capsule for POTS: Vitassium: the only capsule option, designed specifically for dysautonomia patients. 500mg sodium, $0.50/serving. No taste, no mixing. Trade-off: no magnesium and you'll need 6+ capsules daily.
Best ORS for POTS: NormaLyte: 862mg sodium with dextrose for glucose-aided absorption. Markets directly to the POTS community. Worth trying if sugar-free options aren't managing symptoms well enough. 6.75g sugar per serving.
If money isn't the main concern: LMNT: 1,000mg sodium, widely loved for taste, $1.50/serving. The most popular electrolyte brand in online POTS discussions. You're paying a premium for stick pack convenience and flavor quality, but the sodium content is there.
No matter which brand you choose, track your symptoms and work with your healthcare provider to dial in the right daily sodium target. Compare all 17 brands side by side in our full comparison table.
