Buoy Review

What Buoy actually is — and why it's on a weight-loss list

Let's be upfront, because Buoy is easy to misread: it is not a weight-loss program, a GLP-1 prescriber, or a metabolism pill. Buoy (sold at justaddbuoy.com) is a liquid electrolyte drop — a small bottle you squeeze into water, coffee, or any drink — built on an ocean-mineral and whole-food base the brand says carries 87-plus trace minerals, vitamins, and antioxidants. It markets itself as a general hydration product, full stop. We include it in a weight-loss context for one practical reason, and we want you to know it's our editorial call, not Buoy's: people losing weight quickly on semaglutide or tirzepatide often eat and drink far less, and electrolyte loss is a well-documented side effect of that. Buoy is reviewed here as a possible companion to that process — nothing more.

The honest verdict: a hydration adjunct, not a treatment

If you're on a GLP-1 medication and you feel wiped out, foggy, crampy, or lightheaded because your appetite has cratered and you're simply not taking in enough fluid or minerals, an electrolyte product like Buoy can be a sensible, low-effort add-on. What it cannot do is cause or accelerate weight loss, and it should never replace medical advice if your symptoms are significant. Think of it the way you'd think of a good water bottle or a fiber supplement: a supporting actor in the routine, not the thing doing the work.

How the liquid format earns its keep

The most genuinely distinctive thing about Buoy is the delivery. Most electrolyte products are powders or fizzy tablets — you have to dedicate a glass of water to them and taste them. Buoy is a concentrated drop you add to whatever you're already drinking, which makes it far easier to stay consistent. For someone whose appetite is suppressed by a GLP-1 and who is barely interested in food or drink, that low-friction compliance angle is the real selling point. It is also sugar-free with no synthetic sweeteners, per the brand's positioning, which matters if you're watching intake and don't want a sweet electrolyte drink working against you.

• Mixes into any beverage — easier to stick with than a powder you have to prepare separately
• Sugar-free, no artificial sweeteners (per brand positioning) — no hidden calories or sweetener aftertaste
• Genuinely useful when appetite is suppressed — covers electrolytes you may be skipping when you barely want to eat or drink

Pricing: what we could actually confirm

Here's where we have to be careful rather than tidy. Buoy doesn't publish a clean, single monthly rate the way a telehealth service does, so we won't post one as if it were verified. Its storefront sells individual bottles — the Hydration Drops and Rescue Drops lines run in the low-to-mid double digits per bottle, with multi-bottle bundles and an 'every 12 weeks' subscription cadence. The brand also runs a separate, pricier 'Rainforest' line of greens, magnesium, and other products that climb into the high double and low triple digits. The exact subscription per-bottle price isn't exposed without going through the cart, so treat any monthly figure you see quoted as preliminary and confirm it in your own checkout before committing.

A note on our own data

Our listing carries a placeholder monthly subscription row that doesn't map cleanly to a specific bottle on Buoy's live catalog. We're flagging that openly: the real per-bottle and subscription prices come straight from the merchant's store, and that's what you should trust over any rounded estimate.

Trust, oversight, and the limits of our confidence

Two things to hold in mind. First, Buoy is a dietary supplement, not an FDA-evaluated medication — like all supplements, its mineral and antioxidant claims aren't pre-approved by regulators, though we found no FDA or FTC adverse actions against the brand. Second, our own confidence in this entry is deliberately capped. We've confirmed the store is live and the format is real, but the GLP-1-companion framing is ours, not Buoy's, and the granular ingredient-per-serving and pricing details still need a fuller verification pass. We'd rather tell you that than dress up a stub as a thoroughly vetted recommendation. You can read how we grade these in our scoring methodology.

Who should consider it — and who should skip it

• Consider it if: you're on a GLP-1, your appetite is low, and you want a no-fuss way to keep electrolytes up without a sugary sports drink
• Consider it if: you dislike powders and will actually use something you can drip into coffee or water
• Skip it if: you're expecting any effect on weight, appetite, or metabolism — there isn't one
• Skip it (or call your clinician) if: you have clinically significant symptoms like persistent vomiting, fainting, or known electrolyte disorders — that needs medical management, not a supplement

Bottom line

Buoy is a well-made, easy-to-use electrolyte drop that happens to fit a real gap in the GLP-1 weight-loss experience: the dehydration and mineral loss that come with eating far less. As a hydration companion it's a reasonable, convenient pick, and the liquid format is a legitimate advantage over powders. Just keep the frame straight — it's an adjunct, the weight-loss angle is our editorial reasoning rather than the brand's, and you should confirm the current bottle and subscription prices in checkout before you buy. On those honest terms, it can be a small but helpful part of the routine.
