Quick answer
- Choose Liquid I.V. if you are sweating hard, working in heat, travelling, or recovering from a stomach bug. It has about 4x the sodium and real sugar to pull water in.
- Choose Salud if you want a low-sugar, flavored electrolyte drink for mornings or everyday sipping, and you also like the added immune ingredients.
- Skip both as a fix for everyday thirst. Plain water is enough when you are not sweating heavily.
Side-by-side comparison (per stick or packet)
| Feature | Liquid I.V. Hydration Multiplier | Salud Hydration + Immunity |
|---|---|---|
| Serving | 1 stick (16 g) in 16 oz water | 1 packet in 8–12 oz water |
| Sodium | 510–530 mg (22–23% DV) | 130 mg (6% DV) |
| Potassium | 370–380 mg (8% DV) | 212 mg (4% DV) |
| Sugar | 11 g added (cane sugar + dextrose) | 1 g |
| Sweeteners | Cane sugar, dextrose, stevia | Allulose, sucralose, a little sugar |
| Extras | Vitamin C, B3, B5, B6, B12 | Vitamin C, D3, B6, B12, zinc, 250 mg beta glucan, 200 mg coconut water powder, 100 mg elderberry |
| Typical US price | $16.99 for 10 (about $1.70 each) | $10.59 for 6 (about $1.77 each) |
Per-serving cost is almost the same, so the choice comes down to what is in the cup.
Why the sodium and sugar gap matters
Your small intestine absorbs sodium and glucose together through a shared transporter (SGLT1), and water follows. That is the mechanism behind oral rehydration solutions. The WHO reduced-osmolarity ORS formula uses about 75 mmol/L sodium, 75 mmol/L glucose and 20 mmol/L potassium (WHO ORS reference).
Here is how each mix compares once you do the per-liter math at the label’s serving size.
| Per liter | WHO ORS | Liquid I.V. (16 oz) | Salud (8 oz) | Salud (12 oz) |
|---|---|---|---|---|
| Sodium | 75 mmol (about 1,725 mg) | about 49 mmol (about 1,120 mg) | about 24 mmol (about 550 mg) | about 16 mmol (about 366 mg) |
| Potassium | 20 mmol (about 780 mg) | about 20 mmol (about 780 mg) | about 23 mmol (about 895 mg) | about 15 mmol (about 600 mg) |
| Sugar | 13.5 g glucose | about 23 g | about 3–4 g | about 3 g |
What this tells you: Liquid I.V. lands at roughly two-thirds of the ORS sodium level, with potassium right on target. Its sugar is higher than the ORS glucose figure, so it is not a medical ORS, but the sodium-plus-sugar design matches the absorption mechanism. Salud has one-fifth to one-third of the ORS sodium and almost no glucose, so it works as a flavored electrolyte drink rather than a rapid rehydration formula.
These are my calculations from label values, not lab tests, and real products vary a little by flavor.
A note on Salud’s “400+ mg electrolytes” claim
Salud’s label advertises over 400 mg of electrolytes. The listed sodium (130 mg) and potassium (212 mg) add up to 342 mg, so the headline number must also count other minerals or compound weights such as potassium citrate (583 mg) and salt (183 mg). Compare the sodium and potassium lines, not the headline.
Sweeteners and ingredients
Liquid I.V. uses cane sugar and dextrose for function, with a little stevia for taste. Anyone watching sugar, or managing blood sugar, should count the 11 g.
Salud keeps sugar low with allulose and sucralose. Allulose can upset the stomach for some people at larger amounts, which is unlikely at one packet but worth knowing if you are sensitive.
The immunity blend (250 mg beta glucan, 100 mg elderberry, zinc, vitamin C and D3) is a bonus. Evidence for benefits at these doses is limited, so do not buy Salud mainly for immunity.
Which one should you pick?
- Long workout, hot day, hard physical work: Liquid I.V. Salud’s 130 mg of sodium will not cover a heavy sweater’s losses.
- Travel, or a day after a stomach bug: Liquid I.V. for the sodium and sugar. For active vomiting or diarrhea, a proper ORS is the safer choice, and call a doctor if it lasts.
- Mornings, desk days, light activity: Salud. You get flavor, some electrolytes and almost no sugar.
- Cutting sugar: Salud.
- Low-sodium diet, kidney disease or potassium-restricted diet: Check with your doctor before using either one regularly. Both contain potassium, and Liquid I.V. has a lot of sodium.
Frequently asked questions
Is Salud better than Liquid I.V.?
Neither wins everywhere. Liquid I.V. has about four times the sodium per stick and 11 g of sugar, so it suits heavy sweat, heat or stomach illness. Salud has 130 mg sodium and 1 g sugar, so it suits low-sugar daily sipping.
Which has less sugar, Liquid I.V. or Salud?
Salud. One packet lists 1 g of sugar against 11 g of added sugar in a Liquid I.V. Hydration Multiplier stick.
Which is better for a workout or hot day?
Liquid I.V., because its higher sodium and sugar help water absorption during real sweat loss. Salud’s sodium is too low to replace a heavy sweater’s losses.
Does Salud’s immunity blend work?
Salud adds 250 mg beta glucan and 100 mg elderberry per packet. Treat them as a bonus, not the reason to buy; the hydration benefit comes from its electrolytes, and evidence for these doses is limited.
Bottom line
Pick Liquid I.V. when you need to replace what you are losing. Pick Salud when you want a lighter, low-sugar daily drink. If you are not sweating, plain water is still the baseline.
