Buoy Review
One of the few products in our queue that genuinely matters on a GLP-1 — and the flagship is, by the company's own label, a third of a sports drink per serving.
Buoy Ocean Electrolytes
Buy Rescue, Not The FlagshipWhy this one is worth reading: GLP-1 labelling warns about acute kidney injury in people who become volume-depleted through severe nausea, vomiting or diarrhoea. Deliberate hydration during dose escalation is a real clinical concern, so electrolytes are one of the few adjacent products with a legitimate use case here.
But read the panel. Buoy's own supplement facts for the flagship Hydration Drops say: “Per Serving: Electrolytes of ⅓ Sports Drink”, with no milligram sodium figure given. The product with a real load is a different one — Rescue Drops, at a disclosed 300mg sodium per serving, described as “6x stronger, high-sodium”. The affiliate link points at the kit, not at Rescue.
Checked on 8 August 2026: the Ocean Electrolyte Kit was $100 once or $77 on subscription with free monthly shipping, about $1 a day and roughly $0.29 a serving. Subscribe and save 23%, first-order discounts to 31%, HSA/FSA eligible, and a stated discount for customers living with chronic illness. Drops are unflavoured with no sugar or sweeteners — genuinely useful when nausea makes sweet powders intolerable.

What The Labels And Policy Say
Six findings from the supplement facts panels and the refund policy rather than the landing page.
This Category Genuinely Matters Here
GLP-1 labelling warns about acute kidney injury in people who become volume-depleted through severe nausea, vomiting or diarrhoea. Staying hydrated during titration is a real clinical concern, not a wellness slogan
But The Flagship Is Deliberately Light
Buoy's own supplement facts for Hydration Drops state: 'Per Serving: Electrolytes of ⅓ Sports Drink.' That is a third of a sports drink, and sports drinks are themselves weak against a rehydration solution
The Sodium Figure Is On A Different Product
Rescue Drops disclose 300mg of sodium per serving and are described as '6x stronger, high-sodium'. That is the product with a real electrolyte load — and it is a separate purchase
Liquid Drops Are A Real Advantage
No sugar, sweeteners or flavours, added to any drink. If nausea has made sweet powdered drinks intolerable — which is common during dose escalation — that format genuinely helps
The Clinical Claims Are Unverifiable
'64% more than water alone', '49% more than a leading electrolyte' and a '10x positive net fluid balance' are attributed to a 'university-led, crossover design' study with no university named, no participant count and no publication we could find
'Risk-Free' Means Your First Order Only
The product page advertises 'Try 100% Risk Free'. The refund policy states the 30-day guarantee is 'Only applicable to a new customer's first order'
Sodium Is The Number That Matters
If you are buying because of GLP-1 side effects, you are buying sodium. Here is where the products actually sit.
| Option | Sodium disclosed | Use case |
|---|---|---|
| Buoy Hydration Drops | No mg figure; stated as “Electrolytes of ⅓ Sports Drink” per serving | Daily trace-mineral supplement |
| Buoy Rescue Drops | 300mg per serving, 20 servings per bottle | The relevant one for depletion during titration |
| Pharmacy ORS sachet | Defined concentration; WHO formulation ~75 mmol sodium per litre | Cheap benchmark worth pricing against |
| Cannot keep fluids down | Not a shopping problem | Call your prescriber or urgent care |
The bottom row is the one we most want read. Persistent vomiting, inability to keep fluids down, dizziness on standing or passing very little urine are reasons to contact a clinician, because volume depletion on a GLP-1 is a labelled kidney risk. Our side-effects guide covers managing titration, and our provider rankings cover getting proper oversight.

Our Verdict
3.2 / 5 — the right product category for this audience, and the wrong product at the front of it.
We review a lot of things that have no business appearing next to GLP-1 coverage. This is not one of them. The prescribing information for these medicines warns about acute kidney injury in patients who become volume-depleted through severe nausea, vomiting or diarrhoea, so paying deliberate attention to fluid and salt during dose escalation is genuinely worthwhile. Buoy's format helps too: unflavoured liquid drops with no sugar or sweeteners, added to whatever you can face drinking, is a real advantage over a sweet powdered sports drink when nausea has made sweetness intolerable. The subscription can be paused or cancelled from the customer portal, HSA and FSA eligibility is advertised, and there is a stated discount for customers living with chronic illness, which is a decent thing to offer.
The problem is which product the marketing leads with. Buoy's own supplement facts for the flagship Hydration Drops state that a serving delivers 'Electrolytes of ⅓ Sports Drink', with no milligram sodium figure disclosed. A sports drink is itself a weak rehydration fluid next to an oral rehydration solution, so a third of one is a small sodium load however many trace minerals accompany it. The company effectively concedes this by selling Rescue Drops as 'our high-sodium, 6x stronger liquid electrolyte' at a disclosed 300mg of sodium per serving. That is the product a reader with GLP-1 side effects should be looking at — and it is not where the affiliate link goes.
Three further deductions. The headline efficacy claims — 64% more hydrating than water, 49% more than a leading electrolyte, a 10x positive net fluid balance — are attributed to a university-led crossover study with no university named, no participant count, no citation, and a clinical study page that returned 404 for us. Trustpilot holds seven reviews at 2.7, and there is no BBB profile, so despite 11,378 on-site reviews there is essentially no independent record of how problems get handled. And 'Try 100% Risk Free' on the product page becomes, in the refund policy, a guarantee 'Only applicable to a new customer's first order'. Buy Rescue Drops, buy one bottle, compare the price against a pharmacy rehydration sachet, and if you cannot keep fluids down at all then stop shopping and call your prescriber.
Visit BuoyFrequently Asked Questions
Do I actually need electrolytes on a GLP-1?
You need to stay hydrated, and for some people that is a genuinely important clinical issue rather than a wellness nicety — which is why this is one of the few off-category products we think deserves serious consideration. GLP-1 receptor agonists commonly cause nausea, vomiting and diarrhoea, particularly during dose escalation, and they also reduce how much people eat and drink. The prescribing information for these medicines warns about acute kidney injury and worsening of chronic renal failure in patients who become volume-depleted through severe gastrointestinal adverse reactions. In other words, dehydration on a GLP-1 is not just uncomfortable, it can hurt your kidneys. So the underlying idea — deliberately replacing fluid and salts during a phase when you are eating and drinking less and possibly vomiting — is sound and worth acting on. What follows from that, though, is a requirement rather than a recommendation: whatever you use needs to contain enough sodium to matter. Sodium is the electrolyte that drives fluid retention and plasma volume. A product that is mostly trace minerals with very little sodium will not do the job, however good it makes the label look. That is the test we applied here, and it is where the two Buoy products diverge sharply.
Does the flagship product contain enough sodium?
By the company's own description, no — and we want to be careful to use its words rather than ours. Buoy's supplement facts panel for Hydration Drops, the flagship 87-plus trace mineral product, states: 'Serving Size: 1 Short Squeeze (1.5mL). Per Serving: Electrolytes of ⅓ Sports Drink. Per Bottle: 40 Servings. Per Bottle: Electrolytes of 13+ Sports Drinks.' It does not state a sodium figure in milligrams per serving anywhere we could find. So the company itself characterises a serving as one third of a sports drink's electrolytes. For scale, a sports drink is already a weak rehydration fluid — the World Health Organization oral rehydration formulation contains roughly 75 millimoles of sodium per litre, on the order of 1,700mg of sodium per litre, and typical sports drinks contain a small fraction of that. One third of a sports drink per serving is therefore a very modest sodium load in absolute terms. The corroborating evidence is Buoy's own product line: it sells a separate product, Rescue Drops, which it markets as 'our high-sodium, 6x stronger liquid electrolyte for intense depletion and rapid recovery' at a disclosed 300mg of sodium per serving. A company does not need a six-times-stronger high-sodium version unless the standard version is light.
So which product should I buy?
If your reason for buying is GLP-1 side effects, Rescue Drops rather than the flagship — and note that the affiliate link on this page points at the Ocean Electrolyte Kit, not at Rescue Drops. Rescue Drops disclose 300mg of sodium per serving from two short squeezes, 20 servings per bottle, and the company describes them as equivalent to the electrolytes of 39 sports drinks per bottle. Three hundred milligrams of sodium is a real number that you can compare against other products and against what your clinician suggests. It is still not an oral rehydration solution — if you are actively vomiting, cannot keep fluids down, are passing very little urine, or feel dizzy on standing, that is a call to your prescriber or urgent care, not a supplement purchase. But as a way to add meaningful sodium to water during a rough week of dose escalation, it is a coherent product with a disclosed dose. The flagship Hydration Drops are better understood as a daily trace-mineral supplement than as a rehydration tool. If that is what you want, fine — just do not buy it expecting it to protect you from volume depletion, because a third of a sports drink will not.
Is the 'clinically proven to hydrate 64% better' claim real?
We could not verify it, and the way it is presented makes verification unusually hard. The claim appears across the site in several forms: that Buoy electrolytes are 'clinically-proven to hydrate 64% more than water alone and 49% more than a leading electrolyte', that this results in 'a 10x positive net fluid balance', and that the source is a 'university-led, crossover design clinical study'. A crossover design is a legitimate and appropriate method for a hydration study, so the shape of the claim is not implausible. What is missing is everything that would let you check it. No university is named. No participant count is given. No journal, preprint, registry number or author is cited. There is a 'See Clinical Study' link and a 'Science' item in the site navigation, but the clinical study page returned 404 when we tried it, as did our attempts at a science page. We are reporting an inability to verify rather than asserting the study does not exist — it may well sit at a URL we did not guess. But a company that leads with a specific percentage should make the underlying study one click away, and '10x positive net fluid balance' in particular is the kind of phrase that needs a defined endpoint to mean anything. Treat these figures as marketing until you can read the study.
What does it cost?
More than you might expect for salt water with minerals in it. Checked on 8 August 2026, the Ocean Electrolyte Kit — the page the affiliate link lands on — was $100 to buy once or $77 on subscription with free monthly shipping, described as roughly $1 a day, with a one-month supply counted as 265 servings across the products in the kit and a per-serving figure of about $0.29. A three-month supply was offered at 795 servings. Individual products included Digestion Drops around $34, and the site advertised subscription savings of 23% plus first-order discounts of up to 31% with a free gift. HSA and FSA eligibility is advertised, which materially reduces the effective price if you have either. Whether that is good value depends entirely on which product you buy and why. For the flagship, you are paying premium prices for a third of a sports drink's electrolytes per serving plus trace minerals whose benefit is not established. For Rescue Drops at 300mg of sodium per serving, the comparison worth doing is against a standard oral rehydration sachet from a pharmacy, which costs very little and contains a clinically defined sodium concentration. Do that comparison before subscribing.
Is the guarantee as good as it sounds?
It is narrower than the phrase 'Try 100% Risk Free' suggests, and the narrowing is in the policy rather than on the product page. The refund policy sets out a 30-day 'Try Risk-Free' guarantee and states the terms plainly: it is 'Only applicable to a new customer's first order', refunds 'must be requested within 30-days of product delivery', and for the returns route 'All unopened items must be returned (including any free gifts)'. Separately, 'Once an order is created, it cannot be cancelled or modified', and returns must be received within 30 days of the return authorisation. So the honest description is: a genuine any-reason money-back trial, available once, on your first order, if you claim it within 30 days of delivery — not an open-ended satisfaction guarantee on everything you ever buy. That is still better than many supplement companies offer and we would not criticise the substance of it. What we would criticise is the gap between the wording on the product page and the wording in the policy. On the subscription itself the terms are good: you can delay, cancel or modify at any time through the customer portal or the help centre, which is more self-service control than several brands we have reviewed recently.
Are there safety issues with ocean-derived minerals?
Two worth raising, neither of which we can resolve from the website. The first is heavy metals. Seawater-derived mineral concentrates can carry arsenic, lead, cadmium and mercury, because those elements are present in seawater and concentrate along with the desirable minerals. Buoy states that its products are third-party tested, which is the right claim to make, but we were unable to open any certificate of analysis to see whether a heavy metals panel is run or what it showed. If this matters to you — and for a product you intend to take daily, it reasonably might — ask for the heavy metals results for your batch in writing before subscribing. The second is iodine. Marine-sourced products can contain iodine, and excess iodine can cause both underactive and overactive thyroid function. We found no iodine figure disclosed. That is worth asking about specifically if you have any thyroid condition, and it is relevant to this audience because semaglutide and tirzepatide labelling carries a boxed warning about thyroid C-cell tumours, which means many readers are already being monitored around the thyroid. Neither point is an allegation about Buoy's products. Both are questions a careful buyer should get answered.
What about the POTS and IBS claims?
They sit closer to the disease-claim line than a supplement should, and it is worth knowing what you are reading. Rescue Drops are listed as supporting 'POTS Sodium Management, Athlete Performance, Mineral Replenishment, Energy, Migraines'. Digestion Drops are described as 'Anti-bloat, gas, IBS support' and as 'Gentle support for bloating, gas, and IBS symptoms'. POTS — postural orthostatic tachycardia syndrome — and IBS are both diagnosed medical conditions, and migraine is a neurological disorder. A dietary supplement may make structure-function claims but may not claim to treat, mitigate or prevent a disease, which is why the FDA disclaimer appears in the footer. In fairness, the sodium point for POTS is not made up: increased salt and fluid intake is a genuine, mainstream part of POTS management, and a high-sodium product is a rational thing for someone with POTS to use. The problem is one of sequence rather than substance — a product that names your condition invites self-diagnosis and self-management of something that needs a clinician. If you think you have POTS, IBS or chronic migraine, get the diagnosis and the management plan first, then ask whether a supplement fits into it.
Who should buy it and who should not?
Buy Rescue Drops if you are going through GLP-1 dose escalation, you have had nausea or loose stools, you want a way to add real sodium to plain water without a sweet flavoured powder you cannot face, and you accept you are paying a premium for convenience over a pharmacy rehydration sachet. The liquid, unflavoured format is a genuine advantage when everything sweet tastes wrong, and 300mg of sodium a serving is a disclosed and usable number. Buy the flagship Hydration Drops only if you specifically want a daily trace-mineral supplement and are content that a serving is a third of a sports drink's electrolytes. Do not buy either expecting the '64% more hydrating' figure to mean anything until you can read the study behind it. Do not subscribe before you have used a bottle, given that Trustpilot holds only seven reviews and there is no BBB profile — there is almost no independent record of how this company handles problems. And if you are vomiting repeatedly, cannot keep fluids down, are lightheaded on standing or passing little urine, stop shopping and contact your prescriber, because volume depletion on a GLP-1 is a kidney risk that the labelling explicitly warns about.
If You Cannot Keep Fluids Down, Call Your Prescriber
Volume depletion on a GLP-1 is a labelled kidney risk. An electrolyte drop is for topping up during a rough week — not for managing dehydration you are losing control of.
