Hydration
A bubble gum electrolyte stick sounds like a gimmick. The label is where that argument ends.
Five Big League Chew flavors, five published Supplement Facts panels, and the flagship formula they came from. Here is every line, compared.
The instinct is fair. A hydration stick flavored like the shredded gum that came in a foil pouch belongs in the same drawer as protein cookie dough and pre workout candy. Novelty first, formula second, if there is a formula at all.
The instinct is also easy to test, because the answer is printed on the back of the pack and Core Nutritionals puts all five panels on the product page before you buy anything. So this is that test. Every line of the collaboration label, held against the flagship formula it was built from, with nothing rounded and nothing skipped.
Short version for anyone who does not want the arithmetic: the flavors are the only part of this product that came from a candy company.
One
What is actually in one stick
A single stick pack of Big Rally Blue Raspberry weighs 9.4 grams. Here is what those 9.4 grams carry, straight off the panel Core publishes, with the six electrolytes added up at the bottom.
Per stick pack · the six electrolytes
| Line on the panel | Amount | % DV |
|---|---|---|
| Sodiumas sodium citrate | 350 mg | 15% |
| Potassiumcitrate, coconut water concentrate, glycinate chelate | 530 mg | 11% |
| Magnesiumfive forms, including bisglycinate chelate | 139 mg | 33% |
| Calciumcarbonate, citrate, dicalcium malate | 100 mg | 8% |
| Chlorideas magnesium chloride | 43 mg | 2% |
| Zincas zinc bisglycinate chelate | 3 mg | 27% |
| Total electrolytes | 1,165 mg |
Three more actives sit below the electrolyte block, and they are dosed at amounts you can feel the intent behind rather than amounts that exist to be printed:
- L-Taurine, 1,000 mg. A full gram, not a garnish.
- Coconut water concentrate, 500 mg. Which is also one of the three listed sources of the potassium above, so it is doing two jobs.
- ConcenTrace AC trace mineral complex, 100 mg. The trace element package that most electrolyte powders leave out entirely.
Then the three lines at the top of the panel that decide whether this is a sports drink or a candy: 0 calories, 0 grams total carbohydrate, 0 grams total sugars.
That last detail is the one worth pausing on. Every quantity on this label is disclosed individually, including the forms each mineral is delivered in. There is a banner scrolling across the top of every page of the Core store that reads "No Fillers. No Prop Blends. No Pixie Dust. Since 2005.", and the longer version sits on the company page:
Many supplement companies offer fantastic promises with little or no information to back up their claims. Others hide behind secret "proprietary" blends, which may contain only trace elements of the advertised ingredients. We don't take shortcuts or skimp on effective ingredients just to save a buck, and we don't use "fillers." Core Nutritionals, company profile
A company that writes that sentence has to hand you the panel. The interesting part is that they handed it over for the bubble gum one too.
Two
The line that carries the most weight is sodium
Electrolyte marketing loves to count ingredients. Bodies count sodium. It is the mineral you lose most of when you sweat, and it is the one that decides whether the water you just drank stays in you or passes through.
Core's own ingredient write up on this product is blunt about the size of the gap between what a resting body needs and what a training body loses:
While only 500mg of sodium is needed per day for these functions to occur, we as active individuals need far more sodium in order to maintain these functions. We mostly lose sodium through sweat and urine, so the more active we are, the more we sweat and the more we urinate, the more sodium is lost. Core Nutritionals, ingredient breakdown on the Big League Chew HYDRATE page
350 mg per stick is a working dose against that. It is not a salt tablet and it does not pretend to be one, but it is about seventy percent of the 500 mg a resting body needs in a day, by Core's own figure, delivered in one 9.4 gram pack. And you can take two.
The unusual number on this panel is the one right underneath it. Potassium comes in at 530 mg, higher than the sodium. Most of the category runs sodium heavy and treats potassium as a rounding error. Core's own explanation for the pairing is on the same page:
Potassium, as sodium's counterpart, acts as a critical electrolyte primarily by helping to maintain normal levels of fluids inside of our cells. It works very closely with sodium to create the membrane potential needed for the electrical currents that generate these functions to pass from one cell to the next. Core Nutritionals, ingredient breakdown on the Big League Chew HYDRATE page
Sodium holds water in the space around your cells. Potassium holds it inside them. A formula built around the pair is aiming at rehydration rather than at the number on the front of the sachet. It also explains the 500 mg of coconut water concentrate, which the panel lists as one of the potassium sources rather than as a flavor note.
That ingredient write up, incidentally, runs to roughly 1,800 words and closes with sixteen academic references. On a bubble gum flavored product.
Three
Five flavors, five labels, one formula
The obvious place for a licensed collaboration to cut corners is between flavors. Make the hero flavor properly, thin out the other four, and nobody reads far enough to notice.
All five panels are published. Set them side by side and every active is identical, to the milligram, across all five.
Only two things move between the five labels, and neither is an active ingredient.
What changes between flavors
| Flavor | Stick | Color comes from |
|---|---|---|
| Outta Here Original | 9.2 g | Beet root powder |
| Big Rally Blue Raspberry | 9.4 g | Spirulina extract |
| Swingin' Sour Apple | 9.4 g | Beta carotene and spirulina |
| Grand Slam Grape | 9.6 g | Fruit and vegetable juice powder |
| Punch Out Pink Lemonade | 10.4 g | Beet root powder |
Which leads to the detail nobody would have blamed them for skipping. Not one of the five colors is a dye number. A product built on candy nostalgia, in blue raspberry and sour apple and pink lemonade, and the coloring agents are spirulina, beet root, beta carotene and vegetable juice. No Blue 1. No Red 40.
The sweetener is sucralose, listed plainly in other ingredients on all five. If sucralose is a line you do not cross, that is your answer and you can stop reading here. Everything else on the label holds up.

How it stacks up against the formula it came from
This is the comparison that settles the gimmick question, and it is the only one that matters, because Core already sells a hydration formula for people who train seriously. HYDRATE has been on the site for years. If the collaboration is a thinner version of it wearing a costume, the labels will say so.
They are published too. Here is every line of both, in one table.
Per stick pack, both panels
| Line | Big League Chew | HYDRATE |
|---|---|---|
| Vitamin C | 250 mg | 250 mg |
| Calcium | 100 mg | 100 mg |
| Magnesium | 139 mg | 139 mg |
| Zinc | 3 mg | 3 mg |
| Sodium | 350 mg | 350 mg |
| Potassium | 530 mg | 530 mg |
| L-Taurine | 1,000 mg | 1,000 mg |
| Coconut water concentrate | 500 mg | 500 mg |
| ConcenTrace AC | 100 mg | 100 mg |
| Total sugars | 0 g | 0 g |
| Chloride | 43 mg | 557 mg |
| elevATP | none | 150 mg |
| Senactiv | none | 50 mg |
| Sticks per box | 10 | 20 |
| Price per stick | $1.80 | $1.50 |
So the honest verdict, in three sentences. The hydration core of this product is not a lighter version of anything. It is the same nine actives at the same nine doses as the formula Core sells to its own athletes. What the collaboration does not carry is the flagship's two branded performance actives, elevATP and Senactiv, and its chloride sits far lower.
You also pay about thirty cents more per stick, which is what a license from a 1977 bubble gum brand costs. That is a fair thing to know before you decide, and it is a small number next to the fact that the rest of the panel did not flinch.
Five
Why the chloride is lower, and why that is the whole trick
The chloride gap looks alarming until you read the parentheses next to each mineral, which is exactly why Core prints them.
On the flagship, sodium is listed as sodium chloride, sodium citrate and sodium bicarbonate, and potassium includes potassium chloride. Sodium chloride is table salt. Every milligram of sodium delivered that way drags a milligram and a half of chloride along with it, and it tastes like what it is.
On the collaboration, sodium is listed as sodium citrate and nothing else. The chloride that remains, all 43 mg of it, is coming in on the back of the magnesium chloride. There is no salt in the stick.
Same sodium, different vehicle
That is the trade, stated plainly. Chloride does real work: Core's own write up describes it balancing fluid inside and outside cells, supporting blood volume and helping red blood cells exchange oxygen and carbon dioxide. If you are a heavy salt sweater doing long sessions in heat, the flagship's 557 mg is a reason to buy the flagship.
For everyone else, the mineral you are trying to replace is sodium, and it is the same 350 mg either way. The collaboration simply chose the vehicle that lets a bubble gum flavor exist.

What the certification on the box actually promises
Core lists these sticks as Informed Sport Certified. That phrase gets used loosely enough that it is worth knowing what it commits a manufacturer to, because it is the one claim on the front of a supplement box that a stranger can check.
Informed Sport is a batch level program. Product is screened against a banned substance list before it reaches retail, and the certified batches are published in a public register that anyone can search by brand or product. If you have a box in your hand, you can look it up. That is a different order of claim from "third party tested", which is a phrase with no registry behind it.
Two more manufacturing facts Core publishes about its whole line: everything is made in the United States, in cGMP facilities, and the company says it backs product claims with blood work results. Those are their statements, on their company profile, and they are the kind that a competitor would happily challenge if they were loose.
The register is at sport.wetestyoutrust.com. Checking a batch takes about forty seconds and is a good habit with any brand, including this one.
Seven
What people say about the base formula
The collaboration is new enough that its own product page carries no customer reviews yet, so there is nothing to quote about the bubble gum flavors specifically and no point pretending otherwise. The underlying HYDRATE formula has been reviewed on the site for a while, and the reviews that are useful are the ones that talk about the ratios rather than the taste.
This stuff is so good! I mix it with my isoclear after a workout and sip throughout the day. I like the ratios of electrolytes, too much magnesium makes me sleepy but the salt, potassium, etc all seem perfect. Kassandra M., December 3, 2025, on Core's Fun Sweets HYDRATE page
I love the flavor and there is a noticeable difference in my cardio performance and recovery. David Rickert, July 7, 2026, on the HYDRATE product page
Great taste, easy to digest and mixes well with other intra workout supplements. Verified buyer, June 12, 2026, on the HYDRATE product page
All three describe the formula that the collaboration shares nine of its actives with. That is as far as the evidence goes, and it is worth being precise about, on a page whose entire argument is precision.
Eight
Who should buy which one
Both products exist for a reason and the labels make the choice easy.
Big League Chew HYDRATE
- You want the full electrolyte load without a salt finish, because you are sipping it through a session rather than knocking it back.
- You are buying it for a kid's tournament weekend, a job site, a golf round or a long day in heat, and flavor is what makes it get drunk.
- You want five flavors in a run that will not be reordered forever.
Flagship HYDRATE
- You sweat heavily and want the chloride that comes with real salt, 557 mg of it.
- You want elevATP and Senactiv in the same scoop, which the collaboration does not carry.
- You are buying by the box and thirty cents a stick adds up.
What neither of them is: a sugar delivery system. Both panels read 0 grams total sugars and 0 calories, which is the line that separates this shelf from the one holding the drinks most people grew up with alongside the gum.
Nine
How to read any electrolyte label in twenty seconds
Useful beyond this product, and it is the reason a page like this can be written at all.
Four checks, in order
- Find the sodium. Not the ingredient count, not the mineral count. One number, in milligrams, per serving. Everything else on the front of the pack is decoration until you have it.
- Look for the phrase "proprietary blend". If it appears, the individual doses are hidden, and hidden usually means small. A label with a milligram figure next to every line has nothing to hide and knows it.
- Check total sugars, then check the serving size. A low sugar figure on a 4 gram serving of a 40 gram scoop is not a low sugar product.
- Check whether the certification has a register. "Third party tested" is a sentence. Informed Sport, NSF Certified for Sport and Informed Choice are databases you can search. The difference is whether a stranger can verify the claim.
Run those four on the Big League Chew sticks and they pass all four, which is a strange thing to be able to write about a product named after the shredded gum that Rob Nelson started making in the Portland Mavericks bullpen in 1977. The company that put it in a stick pack is headed by a drug free pro bodybuilder and has been printing full disclosure labels since 2005. The joke on the box is real. The panel behind it is not a joke at all.
