Electrolytes is the largest sub-category in Health & Supplement advertising with 141 decoded ads. Curiosity Spike leads with 15.6% adoption, Hyro dominates with 39% of ads, and Problem/Solution is the marketing angle in half of all electrolyte creative.
Electrolytes is the biggest sub-category in Health & Supplement advertising. Bigger than protein, greens, sleep, or collagen. Across 141 decoded ads, one hook leads and one brand runs the field.
Key takeaways
When you look inside the Health & Supplements vertical, electrolytes stands alone. 141 decoded ads. Almost double the size of the next sub-category (vitamins at 77 ads). Triple the size of collagen or protein powder (30 each). Nearly 6x the size of greens powder (25). If you are building creative for a supplements brand and you sell electrolytes, you are competing in the category with the deepest paid-social investment right now.
A Curiosity Spike is an opening beat that plants an information gap in the first 2 to 3 seconds, a specific detail the brain can\'t resolve without watching more. "Best money you\'ve ever spent on a supplement." "How did I not know this?" "Ciao!" Not a claim. Not a question. A fragment that reads as incomplete on purpose. The mechanism is Curiosity Gap: the brain can\'t leave the sentence unresolved.
The brands running this at scale: Hyro, Sodii Hydration, ELYTE Hydration Powder, LVL UP Everyday Hydration, Humantra. The category has clear leaders, clear followers, and a formula that separates the two.
Electrolyte marketers commit to information-gap openings more decisively than the broader Supplements category. Curiosity Spike opens 15.6% of electrolyte ads vs 12.3% of all Supplement ads, a 3-point lift. The pattern is the same, but the concentration is tighter.
Three of the top four openings are information-gap hooks (Curiosity Spike, Contradiction Hook, Open Loop Statement), together they account for 58 of 141 ads, or 41% of the sub-category. Add Contrast Setup and Past-Self Open, both narrative-tension openings, and 55% of electrolyte creative opens by withholding information rather than delivering it.
The strategic implication: electrolyte marketers have converged on "make the viewer curious" as the opening job. If you\'re running a product-shot open or a benefit-first open, you\'re in the minority. That doesn\'t mean the majority is right, but it does mean the tested-and-scaled path in this category is a curiosity opening.
One brand runs the electrolyte category on Meta right now. Hyro produced 55 of the 141 decoded ads, 39% of everything we tracked. The next brand, Sodii Hydration, has 28 ads. After that, drop-off is steep: ELYTE at 10, LVL UP at 6.
The single most concentrated marketing angle in any supplement sub-category. 70 of 141 electrolyte ads frame the message as Problem/Solution, a hydration problem the viewer has, and the product as the direct fix. This is not a mild lean. It is a category consensus.
The specific problems named across those 70 ads: afternoon crashes, workout depletion, morning grogginess, hangover recovery, brain fog, dehydration after air travel, cramp prevention. Every ad picks one and drills into it. Almost none try to communicate multiple problems in the same creative, the winning template is one problem, one solution, one product mention.
Every winning electrolyte ad shares roughly the same structural shape. Duration, angle, format, opening, a repeatable spec that a media buyer briefing production can hand to a creator.

Talking Head (54%)
The talking-head dominance is the most telling number. 54% of electrolyte ads put a person on camera explaining the product, not a produced spot, not a lifestyle b-roll ad, not a motion-graphics explainer. A person. This is the format that carries the mechanism explanation electrolytes require. It also happens to be the cheapest format to produce at velocity, which explains how Hyro can run 55 ads while brands with production-heavy creative strategies run 4.
Three real electrolyte ads running Curiosity Spike + Problem/Solution + Talking Head in the last 90 days. Two Hyro, one Sodii, the two brands responsible for 59% of all electrolyte creative on Meta.
Opening beat"Electrolytes are the best thing you can consume in the morning, without a doubt." Then immediately undercuts common understanding: "Most people have heard of electrolytes, but they just have no idea what they do." The line "Let me break it down for you" signals the reveal.
Why it worksThe mechanism is Information Gap Theory, the viewer is told they don't actually know what they thought they knew. The contrast between "heard of" and "no idea what they do" activates uncertainty, and "let me break it down" converts that tension into Commitment Escalation.
Opening beat"Electrolytes are the best money you've ever spent on a supplement." Then a visual/mental setup: "This vase is going to represent you." Two mysteries in a row, why the extreme value claim, and what the vase metaphor is about to reveal.
Why it worksCompound Curiosity Spike. Each unresolved detail stacks: the counterintuitive value claim + the abstract metaphor. The brain wants to resolve both, which multiplies the pull to keep watching. Metaphor Mapping keeps the viewer's working memory engaged.
Opening beat"Ciao!", a lightweight, unexpected greeting with no context. The viewer doesn't yet know what the video is about, so the brain flags "wait, what's coming next?"
Why it worksMinimal Curiosity Spike. Fragment openings work because they force Completion Bias to activate, staying engaged feels necessary to resolve what the greeting was setting up. Under 6 seconds and the entire hook mechanism is just the ambiguity of an out-of-context word.
The tell across all three: not one names the product benefit in the opening beat. "Electrolytes are the best money you\'ve ever spent" doesn\'t say what electrolytes DO. "Ciao!" doesn\'t even name the category. The benefit arrives at beat 2 or later. Beats 1 is pure withholding.
Six moves your team can ship this week if you sell electrolytes on Meta. Each maps to a specific data point above.
The winning electrolyte ads open with something the viewer can't immediately parse: a counterintuitive assertion ("best money you've ever spent"), a personal admission ("how did I not know this?"), or a fragment ("Ciao!"). Never open with the product name or a benefit. Beat 1 is where curiosity lives; beats 2-4 are where you explain.
70 of 141 electrolyte ads use the Problem/Solution angle, half the entire sub-category. Name a specific hydration problem (afternoon crash, workout depletion, hangover, brain fog) and frame your product as the direct solution. Alternative angles work but at a fraction of the adoption: Offer/Urgency at 12%, Social Proof at 8.5%.
76 of 141 ads use a talking-head variant. Talking Head + B-roll (41 ads) is the highest-volume format. This is not a category where produced spots win, it's a category where a person explaining electrolytes wins. If your creative team is briefing motion graphics or lifestyle-only footage, they are working against the pattern.
Average 40.6s, median 33.1s. Electrolytes require mechanism explanation (why hydration matters, what electrolytes actually do, how yours are different). Under 20 seconds and the science doesn't land. Over 60 and retention breaks. The 30-45 second window is where the winners live.
Hyro produced 55 of the 141 electrolyte ads we decoded, 39% of the entire sub-category. That means they are testing 2-3x more creative than any competitor. Match their volume, or accept that you're building brand awareness at a fraction of their velocity. Every Hyro ad is a learning opportunity for the rest of the category.
Same core problem (say, afternoon energy crash) with 3 different Curiosity Spike openings. That's the format that maps to the data. Rotating hooks within a locked angle beats rotating angles within a locked hook, because Problem/Solution IS the angle that's winning.
The single biggest lever is #5, creative volume. Hyro isn\'t winning because they picked a better hook. They\'re winning because they\'re testing 2-3x more variations of the same winning formula. Every other electrolyte brand needs to either match that velocity or differentiate on angle.
Across 141 decoded electrolyte ads on Meta, the Curiosity Spike opens 22 of them (15.6%). It edges Contradiction Hook (19 uses, 13.5%) and Open Loop Statement (17 uses, 12.1%). The pattern is more concentrated than in the broader Supplements category, electrolyte marketers commit to information-gap openings more often than sleep, protein, or greens marketers do.
Hyro owns 55 of the 141 decoded electrolyte ads, 39% of the entire sub-category. Sodii Hydration follows with 28 ads (20%), then ELYTE Hydration Powder (10), LVL UP Everyday Hydration (6), and Humantra (4). Hyro produces roughly twice the creative volume of every other electrolyte brand combined outside the top two.
Problem/Solution dominates at 70 of 141 ads, exactly 50% of the entire electrolyte sub-category. Offer/Urgency follows at 17 ads (12%), then Social Proof (12 ads, 8.5%), Education Value (10), and Expert Authority (8). This is the highest angle concentration we track in any supplement sub-category, half of all electrolyte creative frames the message the same way: "you have a hydration problem, our product solves it."
Talking head variants dominate at 76 of 141 ads (54%): Talking Head + B-roll (41 ads), Talking Head + Product (35), Talking Head Solo (11), and Founder to Camera (8). Voiceover + B-roll follows at 28 ads. Motion graphics and lifestyle formats each show up under 10 ads. The winning presentation is a person on camera explaining the product, not a produced commercial.
The 141 decoded ads average 40.6 seconds with a median of 33.1 seconds. That is longer than most retail sub-categories, the extra runtime is needed to explain the "why" of electrolytes (dehydration, electrolyte loss, mechanism of action) before making the pitch. Under 20 seconds and the science doesn't land. Over 60 seconds and retention breaks.
Electrolytes is the largest single sub-category we track within Health & Supplements, 141 ads across 8+ brands with active creative. The GLP-1 boom, the resurgence of hydration-first health content on TikTok, and the shift toward "clean supplements" have all converged. Hyro cracked the code first (Curiosity Spike + Problem/Solution + Talking Head, ~40 seconds) and every other brand is now competing against that formula.
