LMNT for POTS is a solid choice on paper. Each stick pack delivers 1,000mg sodium, zero sugar, and comes pre-measured for portability. The formula has the right foundation for POTS-level sodium needs: high sodium concentration, clean ingredients, and no glucose that could complicate things for patients with MCAS overlap. The issue is cost. POTS patients typically need 3–10 packets per day,[1] which runs $4.50–$15.00 daily. Six other brands deliver the same or more sodium for less money.
What's in LMNT?
Each LMNT stick pack contains:
- Sodium: 1,000mg (from sodium chloride, sodium citrate, sodium malate)
- Potassium: 200mg
- Magnesium: 60mg
- Sugar: 0g (sweetened with stevia)
- Price: $1.50 per stick pack ($45.00 for 30 packets)
The sodium content ties for the highest of any electrolyte brand in our 17-brand comparison. Only Hydrate Pro and Zerolyte match it at 1,000mg. SALTT comes close at 969mg.
One thing to note: LMNT's sodium-to-potassium ratio is 5:1 (1,000mg sodium to 200mg potassium). Some dietitians who work with POTS patients recommend a ratio closer to 2:1 or 3:1, since potassium supports heart rhythm and muscle function alongside sodium for blood volume. Individualized nutritional strategies are important for dysautonomia patients because overlapping conditions can affect electrolyte needs.[2] If you're using LMNT as your primary electrolyte, you may want to supplement potassium separately or look at brands with more balanced ratios. SALTT (969mg sodium, 415mg potassium, 2.3:1 ratio) and Redmond Re-Lyte (810mg sodium, 400mg potassium, 2:1 ratio) offer notably more potassium per serving.
LMNT's magnesium at 60mg per serving is also modest. While it's more than some competitors (Vitassium and NormaLyte have zero magnesium), SALTT packs 178mg per serving. Many POTS patients supplement magnesium separately, so this may not be a deciding factor depending on your regimen.
How Much LMNT Do POTS Patients Need?
The 2021 POTS Expert Consensus recommends 3,000–10,000mg of sodium daily, paired with 2–3 liters of fluid.[1] A clinical trial by Garland, Raj et al. confirmed that high sodium intake increased plasma volume and reduced standing heart rate in POTS patients compared with a low-sodium diet.[3] Most patients aim for the 3,000–5,000mg range from supplements and food combined.
These numbers are total daily sodium, including food. Most people consume around 3,000mg from food alone, which means some patients at the low end may need little supplementation, while those targeting 5,000–10,000mg need substantial supplemental sodium throughout the day.
At 1,000mg per packet, here's what LMNT costs at different sodium targets (from supplements alone):
| Daily Sodium Target | LMNT Packets | Daily Cost | Monthly Cost | Annual Cost |
|---|---|---|---|---|
| 3,000mg (minimum) | 3 | $4.50 | $135 | $1,643 |
| 5,000mg (moderate) | 5 | $7.50 | $225 | $2,738 |
| 10,000mg (high) | 10 | $15.00 | $450 | $5,475 |

Even at the minimum 3,000mg target, LMNT costs $135/month or $1,643/year. At the moderate 5,000mg level, it's $225/month. POTS is chronic, which means this is a recurring expense with no end date. That annual cost figure is what drives many POTS patients to look for alternatives.
How Does LMNT Compare for POTS?
We compared LMNT against every brand in our comparison table with 500mg+ sodium per serving. The table below ranks them by daily cost to reach 3,000mg sodium.
| Brand | Sodium | $/Serving | Daily Cost @3g | K (mg) | Mg (mg) | Form |
|---|---|---|---|---|---|---|
| Hydrate Pro | 1,000mg | $0.78 | $2.34 | 200 | 60 | Tub/Scoop |
| Redmond Re-Lyte | 810mg | $0.75 | $2.78 | 400 | 50 | Tub/Scoop |
| Vitassium | 500mg | $0.50 | $3.00 | 100 | 0 | Capsules |
| Zerolyte | 1,000mg | $1.20 | $3.60 | 150 | 50 | Stick Pack |
| SALTT | 969mg | $1.17 | $3.62 | 415 | 178 | Stick Pack |
| Santa Cruz Paleo | 800mg | $1.00 | $3.75 | 300 | 75 | Tub/Scoop |
| LMNT | 1,000mg | $1.50 | $4.50 | 200 | 60 | Stick Pack |
| NormaLyte | 862mg | $1.33 | $4.63 | 393 | 0 | Stick Pack |

LMNT ranks 7th out of 8 high-sodium brands on daily cost. Hydrate Pro delivers the same 1,000mg sodium, 200mg potassium, and 60mg magnesium for $0.78/serving instead of $1.50. The formulas are nearly identical in mineral content. The difference is form factor: Hydrate Pro uses a tub and scoop, LMNT uses individual stick packs.
The savings from switching add up. Going from LMNT to Hydrate Pro at 3,000mg/day saves $2.16/day, or $65/month, or $788/year. At 5,000mg/day, the gap widens to $3.60/day ($108/month, $1,314/year).
If you specifically want stick packs, Zerolyte ($3.60/day) and SALTT ($3.62/day) both cost less than LMNT with comparable sodium. SALTT stands out for mineral coverage: 969mg sodium, 415mg potassium, and 178mg magnesium in a single packet. That's better across all three minerals than LMNT for $0.88 less per day.
LMNT for POTS: Pros and Cons
What works well:
- 1,000mg sodium per packet. Among the highest of any brand. Fewer packets needed to reach POTS targets. Salt supplementation has been shown to improve symptoms and plasma volume in POTS patients.[4]
- Zero sugar. No glucose crash, no carbs, clean for patients with MCAS overlap.
- Stick packs are portable. Toss them in a bag for appointments, work, or travel.
- Wide flavor selection. Multiple options help when you're drinking 3–5 servings daily. Taste fatigue is real when you're doing this every day, so having flavors to rotate through keeps the routine sustainable.
- Widely recognized in POTS communities. Easy to find, well-reviewed, and frequently discussed in dysautonomia support groups.
What doesn't:
- $4.50/day minimum. Over $1,600/year. Chronic daily use makes this a significant ongoing expense.
- 5:1 sodium-to-potassium ratio. Brands like SALTT (2.3:1) and Re-Lyte (2:1) provide more potassium relative to sodium.
- Only 60mg magnesium. SALTT provides 178mg per serving. You may need separate magnesium supplementation with LMNT.
- GI sensitivity at high doses. Some patients report stomach discomfort from 3+ concentrated packets daily. Diluting in more water and spacing doses throughout the day can help.
Stick Packs vs. Tubs for Daily POTS Use
LMNT only comes in stick packs. For daily POTS use, this creates a cost premium. Stick packs are convenient for on-the-go situations, but most POTS patients take the majority of their electrolytes at home.
Tub-format brands like Hydrate Pro, Redmond Re-Lyte, and Santa Cruz Paleo cost 30–48% less per serving than LMNT. You measure with a scoop and mix into water. Less convenient than tearing open a packet, but meaningfully cheaper across months and years of daily use.
A practical approach some POTS patients use: keep a tub-format electrolyte at home for daily baseline doses and carry a few stick packs in your bag for away-from-home use. This captures the portability benefit without paying the stick pack premium on every serving. If you take 3 servings daily and 2 of them are at home, switching those to Hydrate Pro ($0.78/serving) while keeping one LMNT stick pack ($1.50) for portability brings your daily cost from $4.50 to $3.06.
The Bottom Line
LMNT is a good electrolyte for POTS. The formula delivers: 1,000mg sodium, zero sugar, convenient stick packs. If you can afford $135+/month on electrolytes, it works well and the flavor variety makes high-volume daily dosing more manageable.
If cost matters (and for most people managing a chronic condition, it does), six brands deliver the same or better sodium for a lower daily price. The closest formula match is Hydrate Pro: identical sodium, potassium, and magnesium for $0.78/serving. The best overall mineral profile belongs to SALTT: 969mg sodium, 415mg potassium, and 178mg magnesium for $1.17/serving.
