Sea Moss Hydration vs. LMNT vs. Liquid I.V.: An Honest Comparison

By Dr Arsham Najeeb August 25, 2026 8 min read
Three glasses of electrolyte drinks in pink, yellow, and clear, lined up for a side-by-side hydration drink comparison.

Short version: LMNT gives you the most sodium per scoop, Liquid I.V. leans on sugar to help you absorb its electrolytes faster, and Sea Moss Hydration with Creatine sits in the middle on sodium while adding 3,000mg of creatine monohydrate and 800mg of wildcrafted sea moss that neither of the other two has. Which one is "best" depends on what you're actually trying to do. We make one of these three, so read the numbers and decide for yourself.

We're not going to pretend LMNT and Liquid I.V. are bad products. They're not. Both have loyal followings for good reasons, and both do the basic job of an electrolyte mix: replace what you sweat out. Where they differ is in approach, and that's worth spelling out plainly instead of hand-waving.

What does each brand actually optimize for?

LMNT is built around high sodium. A serving lands around 1,000mg of sodium, no sugar, and the flavored versions use stevia. That's a deliberate bet: a lot of endurance athletes, keto dieters, and heavy sweaters lose more sodium than a "balanced" formula replaces, so LMNT just gives them a lot of it. If you're doing long training blocks in heat, or you're fasted and low-carb and feeling the classic keto-flu sluggishness, that much sodium can genuinely help. Credit where it's due.

Liquid I.V. takes a different route. Classic formula has roughly 500mg of sodium and about 11g of sugar, and that sugar isn't filler: it's there because Liquid I.V.'s whole pitch is built on Cellular Transport Technology, which uses glucose to help sodium and water move across the gut wall faster. Whether you find that meaningfully better than plain water plus salt is a fair thing to be skeptical about, but the mechanism itself (glucose-assisted sodium absorption) is real physiology, not marketing fiction. If you want something that tastes like a juice box and you're not worried about the sugar, it's a reasonable pick.

Sea Moss Hydration with Creatine takes a third path. Moderate sodium (300mg, 13% DV), plus potassium citrate, magnesium citrate, coconut water powder for a bit of natural electrolyte backup, 800mg of wildcrafted Irish sea moss (Chondrus crispus) for trace minerals, and 3,000mg of creatine monohydrate. It's sweetened with monk fruit: no stevia, no sugar. And it's the only one of the three built around creatine at all.

Does Sea Moss Hydration have less sodium than LMNT?

Yes, honestly. 300mg versus roughly 1,000mg isn't close. If you're a heavy sweater, training in real heat, or doing strict keto and chasing that specific high-sodium feeling, LMNT's numbers may suit you better, and we're not going to spin that. Some people want LMNT-level sodium, full stop. What we'd say is that 300mg is a solid amount for daily use, enough to matter without being uncomfortable to drink every day, paired with minerals and creatine that LMNT doesn't offer at all.

Why doesn't Sea Moss Hydration use sugar like Liquid I.V.?

Because we didn't want the daily habit to come with 11g of sugar attached. Liquid I.V.'s sugar is functional, not just for taste, but it's still sugar, every single day, if that's your only electrolyte drink. Monk fruit gets us sweetness without that tradeoff. This isn't a knock on Liquid I.V.'s formulation logic, just a different design decision for a product meant to be a daily stick pack rather than an occasional rehydration fix.

What does creatine add that neither competitor has?

Neither LMNT nor Liquid I.V. contains creatine. That's not us being cute about differentiation. It's just not part of either formula. Creatine monohydrate is one of the most studied supplements that exists, with a research base built over decades, and it's mostly known for supporting strength and power output during training, plus pulling water into muscle cells (more on that in a second, because it gets misunderstood constantly). Pairing it with a daily electrolyte habit is just practical: you're already drinking it every day, so it's an easy vehicle. Is the combination magic? No. It's a workhorse ingredient and a hydration ingredient sharing a stick pack. That's the whole pitch.

What's in the sea moss that isn't in a plain electrolyte mix?

Sea moss brings a broad trace mineral profile: iodine, zinc, and a long tail of others in smaller amounts, plus 250mg of additional trace minerals in the formula on top of that. You've probably seen the claim that sea moss contains dozens of the minerals your body uses. We hold that number loosely; it comes from wellness lore more than a single rigorous source. What we can say with confidence is that sea moss has a genuinely broad mineral profile, which is different from what pink Himalayan salt alone gives you (mostly sodium chloride, with only trace amounts of anything else).

Sea Moss Hydration vs. LMNT vs. Liquid I.V.: the numbers

Metric Sea Moss Hydration with Creatine LMNT Liquid I.V. (Classic)
Sodium 300mg (13% DV) ~1,000mg ~500mg
Potassium 300mg citrate (6% DV) Present; check current label for exact amount Present; check current label for exact amount
Sugar 0g 0g ~11g
Sweetener Monk fruit Stevia (flavored versions) Cane sugar / glucose
Creatine 3,000mg monohydrate None None
Sea moss / trace minerals 800mg wildcrafted sea moss + 250mg trace minerals None None
Price $29.99 per box Varies by retailer and bundle Varies by retailer and bundle

We left competitor pricing out rather than guess at numbers that change by retailer and bundle size. Our number is our number: $29.99 for the box.

Who should actually pick which one?

If you're doing long, hot, sweaty training sessions and need maximum sodium replacement, LMNT's formula is built for exactly that. If you want something that tastes like a treat and don't mind the sugar, and you buy the glucose-assisted absorption logic, Liquid I.V. does what it says. If you want a daily electrolyte habit that also covers creatine and a trace mineral base without added sugar, that's the lane Sea Moss Hydration with Creatine is built for. None of these are wrong answers. They're different tools.

Some people stack more than one. A distance runner might use LMNT during a long race for the sodium load, then keep a daily stick pack of something lower-sodium for the rest of the week. There's nothing wrong with mixing and matching based on what a given day actually demands, since sitting at a desk calls for less sodium than four hours outside in July. The mistake is assuming one formula has to cover every scenario. It doesn't, and no honest brand should claim otherwise.

Price is where this gets murkier than people expect, because per-serving cost swings with where you buy, whether you subscribe, and what size box you get. That's exactly why we didn't put a number in that table for LMNT or Liquid I.V.; we'd rather leave a blank than print something that's wrong by the time you read it. What we can tell you with certainty is our own number: $29.99 for a box of Sea Moss Hydration with Creatine, no subscription tricks required to see the real price.

Frequently asked questions

Is LMNT or Sea Moss Hydration better for keto?

If you specifically want very high sodium to manage keto-flu symptoms, LMNT's roughly 1,000mg per serving is more sodium than Sea Moss Hydration's 300mg. Some keto dieters do fine with the lower amount plus food sources of sodium; heavy sweaters on keto often want more.

Does Liquid I.V. actually absorb faster than water?

The mechanism it relies on, glucose helping sodium and water cross into the bloodstream, is a legitimate physiological pathway, sometimes called cellular transport. Whether the real-world difference feels significant to you is something individuals report differently.

Does Sea Moss Hydration have sugar?

No. It's sweetened with monk fruit: zero sugar, zero stevia.

Why would I want creatine in an electrolyte drink?

Mostly convenience. Creatine monohydrate is typically taken daily regardless of training day, and an electrolyte stick pack is also a daily habit for a lot of people, so combining them just removes one extra thing to remember.

Is 300mg of sodium enough for daily hydration?

For most people on a normal diet doing regular activity, yes: 300mg is a meaningful daily contribution, especially alongside potassium and magnesium in the same formula. Heavy sweat loss, endurance training, or specific medical sodium needs may call for more, and that's worth discussing with your doctor.
