The best budget electrolyte powder isn't the one with the lowest price per serving. It's the one with the lowest price per gram of sodium. Sodium is the primary electrolyte lost in sweat,[1] and sodium content ranges from 55mg to 1,000mg per serving across the 17 brands in our comparison table, which means price per serving tells you almost nothing about actual value.
Hydrate Pro is the best value at $0.78 per gram of sodium. Key Nutrients looks cheapest at $0.33/serving, but each serving has only 110mg sodium, making it $3.00 per gram. Ultima Replenisher at $0.53/serving seems affordable until you realize it has just 55mg sodium, costing $9.64 per gram. The price per serving rankings that every other comparison uses are misleading.
Why Price Per Serving Is the Wrong Metric
Every electrolyte comparison site ranks brands by price per serving. The problem: a "serving" means completely different things across brands.
One serving of LMNT contains 1,000mg sodium. One serving of Ultima Replenisher contains 55mg. That's an 18x difference. Research shows sodium intake directly affects endurance performance,[2] so the amount per serving matters far more than the price per serving. Comparing their per-serving prices ($1.50 vs. $0.53) without normalizing for sodium content is like comparing the price of a gallon of gas to a cup of gas.
Here's the math that reveals the real picture. To get 1,000mg of sodium:
- Hydrate Pro: 1 serving = $0.78
- LMNT: 1 serving = $1.50
- Key Nutrients: ~9 scoops = $3.00
- Ultima Replenisher: ~18 scoops = $9.64
Ultima looks like the budget pick at $0.53/serving. It's actually the second most expensive brand in our comparison when you normalize for sodium. Price per gram of sodium flips the rankings entirely.
All 17 Brands Ranked by Cost Per Gram of Sodium
Here's every brand in our comparison, sorted by the metric that actually measures value: what you pay per gram of sodium.
| Brand | Sodium | $/Serving | $/g Sodium | K | Mg | Sugar | Form |

The spread is enormous. Hydrate Pro delivers sodium for $0.78 per gram. Nectar charges $10.60 per gram. That's a 13.6x difference. Sorting by price per serving would rank Key Nutrients ($0.33) first and Hydrate Pro ($0.78) seventh. Sorting by price per gram of sodium puts Hydrate Pro first and Key Nutrients eleventh. The rankings flip completely.
Best Budget Electrolyte Powder by Format
Format affects price more than most people realize. Tub and scoop products are consistently cheaper than stick packs because you're not paying for individual packaging, portability, or single-serve convenience.
Tub/Scoop (4 brands): Hydrate Pro ($0.78/g), Redmond Re-Lyte ($0.93/g), Santa Cruz Paleo ($1.25/g). These three dominate the value rankings. Key Nutrients ($3.00/g) and Ultima ($9.64/g) are also tub format but have very low sodium per scoop, which kills their value. If you use electrolytes daily at home, tub format saves real money.
Stick Packs (10 brands): Range from $1.20/g (Zerolyte) to $10.60/g (Nectar). The cheapest stick packs are Zerolyte ($1.20/g) and SALTT ($1.21/g), both with ~1,000mg sodium per packet. LMNT at $1.50/g is mid-pack. If you need portability, Zerolyte and SALTT give you the most sodium per dollar.
Capsules (1 brand): Vitassium at $1.00/g sodium. No taste, no mixing, no cleanup. Capsules are a surprisingly cost-effective format because there's zero flavoring or sweetener cost. The tradeoff: you need to drink water separately.
Tablets (1 brand): Nuun Sport at $1.73/g sodium. Drop a tablet in water and let it fizz. Convenient but only 300mg sodium per tablet, which drags the value down.
Monthly Cost: What Electrolytes Actually Cost Over Time
Nobody runs this math, but it matters. If you take electrolytes daily, the monthly cost difference between brands is significant. Here are the six most cost-effective brands at 1 serving per day versus 3 servings per day, compared against LMNT as a popular baseline.
| Brand | $/Serving | Na/Serving | Monthly (1/day) | Monthly (3/day) |
|---|---|---|---|---|
| Vitassium | $0.50 | 500mg | $15.00 | $45.00 |
| Redmond Re-Lyte | $0.75 | 810mg | $22.50 | $67.50 |
| Hydrate Pro | $0.78 | 1,000mg | $23.40 | $70.20 |
| Santa Cruz Paleo | $1.00 | 800mg | $30.00 | $90.00 |
| SALTT | $1.17 | 969mg | $35.10 | $105.30 |
| Zerolyte | $1.20 | 1,000mg | $36.00 | $108.00 |
| LMNT | $1.50 | 1,000mg | $45.00 | $135.00 |

At 3 servings per day, switching from LMNT to Hydrate Pro saves $64.80 per month ($777.60/year) while delivering identical sodium. Even switching to Zerolyte (same sodium, same stick pack format) saves $27.00/month ($324/year).
The sodium column matters here too. Vitassium is the cheapest monthly at $15.00 for 1 serving per day, but that's only 500mg sodium. Hydrate Pro costs $8.40 more per month but delivers double the sodium (1,000mg). If you need serious sodium supplementation for keto[3] (which increases sodium excretion), carnivore, POTS[4] (where high sodium intake reduces orthostatic tachycardia), or heavy sweating, look at monthly cost alongside sodium per serving, not monthly cost alone.
One pattern worth noting: the gap between brands widens as usage increases. At 1 serving per day, the difference between Hydrate Pro and LMNT is $21.60/month. At 3 servings per day, it's $64.80/month. Daily users have the most to gain by choosing a cost-effective brand. Occasional users (a few times per week) may not notice the difference enough to switch.
The Bottom Line
Best overall value: Hydrate Pro. $0.78 per gram of sodium. 1,000mg sodium, 200mg potassium, 60mg magnesium per serving. Tub format, 45 servings for $34.99. If you want the most sodium per dollar, this is it.
Runner-up with more potassium: Redmond Re-Lyte. $0.93/g sodium. 810mg sodium and 400mg potassium per serving. Tub format, 60 servings for $44.99. Slightly more expensive per gram of sodium but delivers double the potassium of most competitors.
Cheapest stick pack: Zerolyte. $1.20/g sodium. 1,000mg sodium per packet. If you need individual servings for travel or the gym, this is the best value in stick pack format at $1.20/serving.
Most minerals per dollar: SALTT. $1.21/g sodium. 969mg sodium, 415mg potassium, 178mg magnesium per serving. Nearly as cheap as Zerolyte per gram of sodium but with significantly more potassium and magnesium.
Stop comparing price per serving. Start comparing price per gram of sodium. The difference can save you hundreds of dollars per year.
