Buoy Hydration Drops are a flavourless, sugar-free liquid electrolyte with 87 trace minerals, added to any drink, from $30.03 for 120 servings.
Overview
Buoy makes liquid electrolyte drops designed to be added to any beverage rather than mixed as a drink in their own right. The flagship formula contains ocean-sourced electrolytes and 87 trace minerals, with no sugar, no sweeteners and no flavourings. The company cites clinical work supporting a claim to hydrate 64 percent more than water alone. It sells from $30.03 for 120 servings, and holds 4.8 out of 5 across more than 5,400 reviews.
The absence of flavour is the whole proposition, and for this audience it is the right one. GLP-1 medications alter taste and cause nausea, and many people find sweetened electrolyte drinks actively unpleasant during treatment. A dropper that disappears into coffee, tea or plain water sidesteps that entirely. Buoy publishes content aimed specifically at GLP-1 users, including on semaglutide fatigue and hydration, which suggests the fit was noticed rather than invented.
Two things are worth being realistic about. The sodium content is lower than dedicated high-sodium products such as LMNT, which delivers 1,000mg per serving, so if heavy sweating or significant fluid loss is your situation Buoy may be under-dosed for it. And 87 trace minerals is a marketing figure more than a mechanism; the primary electrolytes do the work. Neither undermines the product, which addresses one problem cheaply and effectively without claiming anything about appetite or weight.

Supplement or Medication?
A dietary supplement, and a straightforwardly nutritional one. Electrolytes replace what fluid loss removes. Nothing here acts on GLP-1, appetite or weight, and Buoy does not claim otherwise.
How You Buy It
Buy direct or on Amazon
Available from Buoy and Amazon at 120 servings a bottle.
Add to whatever you drink
The drops are flavourless, so coffee and tea work as well as water.
Use it when fatigue or cramps appear
Both are common and often fluid-related on a GLP-1.
Consider a higher-sodium option if you sweat heavily
LMNT delivers considerably more sodium per serving.
Who It Is Sold To
- Adults on GLP-1 medication experiencing fatigue or cramps
- No consultation or clinical assessment involved
- Anyone who cannot tolerate sweetened electrolyte drinks
- People on sodium-restricted diets should check with a clinician
- Not appropriate as a substitute for prescribed obesity treatment
- Persistent fatigue warrants a clinical conversation, not just electrolytes
Clinical Oversight and Evidence
Clinical Oversight
None. This is a retail supplement with no clinical involvement. If you have heart or kidney conditions, or are on a sodium-restricted diet, electrolyte supplementation is worth raising with your clinician.
Evidence
Modest and appropriately scoped. Buoy cites clinical work supporting its 64 percent hydration claim. The broader case, that GLP-1 medications increase the risk of dehydration and electrolyte imbalance through reduced intake and gastrointestinal losses, is well recognised and discussed by electrolyte brands and clinicians alike. No GLP-1 specific trial exists on this product.

Frequently Asked Questions
Why does the lack of flavour matter?
GLP-1 medications alter taste and cause nausea, and many people find sweetened electrolyte drinks unpleasant during treatment. A flavourless dropper disappears into whatever you are already drinking.
How much does it cost?
From $30.03 for 120 servings, which is around 25 cents a serving. That makes it one of the cheapest products covered here.
Is there enough sodium in it?
For ordinary daily use, generally yes. If you sweat heavily or have significant fluid losses, a dedicated high-sodium product such as LMNT, which delivers 1,000mg per serving, may suit you better.
What are the 87 trace minerals for?
Mostly marketing. The primary electrolytes do the work of fluid balance. The trace mineral count is a differentiator rather than a mechanism.
Will it help with weight loss?
No, and Buoy does not claim it will. It addresses hydration, which affects fatigue and cramps rather than weight.
Can I put it in coffee?
Yes, that is the point of the format. It has no flavour, so it works in coffee, tea, juice or plain water.
Is it FDA approved?
No. It is a dietary supplement, so it does not require FDA approval before marketing and its claims have not been evaluated by the FDA.
