Buoy Review: Actually Relevant Here
Buoy makes concentrated liquid electrolyte drops — unflavoured, added to water, coffee or anything else you drink — plus wild superfood blends, priced from about $15.75 to $100 for larger bundles. Unlike most products we cover from this affiliate queue, this one has a direct and genuine connection to GLP-1 treatment: eating and drinking substantially less means taking in fewer electrolytes, and that is a common cause of the fatigue, headaches and cramps people report in early treatment.

Verdict: A sensible, well-designed product solving a real problem for anyone whose intake has dropped sharply. The unflavoured liquid format is the genuine advantage — it works in drinks you already have rather than requiring you to want a flavoured sports drink. Not a treatment for anything, and cheaper alternatives exist.

Electrolytes are useful, not essential
If you are lightheaded, headachy or cramping in early GLP-1 treatment, inadequate fluid and electrolytes are a common and easily fixed cause. But adequate water and attention to salt in food cover most people for free. Buy this for convenience and consistency, not because you need it — and check with a clinician first if you have kidney disease, heart failure, or take medication affecting potassium.
Plain salt, potassium from food, and adequate water cover most people's needs for free. This is a convenience product, and a good one — but do not treat it as a requirement.
Why This Matters on a GLP-1
GLP-1 medications reduce appetite substantially, which means less food, less fluid and fewer electrolytes — sodium, potassium and magnesium — than your body is accustomed to. Lightheadedness, headaches, fatigue and night cramps in the first weeks of treatment are frequently traced to exactly that.
It is a genuinely fixable problem, and one of the more common reasons people feel worse than they expected early on. Our supplements guide covers where electrolytes sit relative to fiber, protein and creatine, which generally matter more.
What the Product Is
Concentrated unflavoured drops rather than a flavoured powder. That matters practically: you can add them to coffee, tea or plain water without changing the taste, which makes consistent use easier than a sports drink you have to want to drink.
Electrolyte supplements are not reviewed by the FDA for safety or effectiveness. People with kidney disease, heart failure or on medications affecting potassium — including some blood pressure drugs — should check with a clinician before adding potassium supplements, as excess potassium is genuinely dangerous.

Pros and Cons
Strengths
- Unflavoured, so it works in any drink rather than requiring a flavoured one
- Directly addresses a real and common early GLP-1 problem
- Liquid concentrate is more portable than powder sachets
- Entry pricing from about $15.75
- Subscription available for consistent use
- No added sugar, unlike many sports drinks
Drawbacks
- Adequate water and dietary salt cover most people's needs for free
- Bundles to around $100 are a significant outlay for electrolytes
- Not FDA-reviewed for safety or effectiveness
- Potassium supplementation needs caution with kidney, cardiac or blood pressure medication
- Not a treatment for the underlying cause of fatigue
Who Should Pick It — and Who Shouldn't
Good fit
Anyone whose food and fluid intake has dropped sharply — which describes most people in early GLP-1 treatment — and who wants electrolytes without a flavoured sports drink. Also useful for heavy sweating or after illness.
Look elsewhere
Anyone with kidney disease, heart failure or on potassium-affecting medication, without clinician advice. Anyone on a budget, where salt and food cover it. And anyone whose fatigue persists despite good hydration, which warrants investigation rather than more supplements.
Frequently Asked Questions
How much does Buoy cost?
From about $15.75 for a single bottle, with bundles around $100 and subscription discounting available.
Do I need electrolytes on a GLP-1?
Often, yes. Eating and drinking much less means fewer electrolytes than your body is used to, and that is a common cause of lightheadedness, headaches and cramps in the first weeks. Adequate water plus attention to salt covers many people; a supplement helps if symptoms persist.
What makes Buoy different from powders?
It is an unflavoured liquid concentrate, so it goes into drinks you already have — coffee, tea, plain water — rather than requiring you to want a flavoured sports drink. That makes consistent use easier.
Is it safe to supplement electrolytes?
For most people, yes. But potassium supplementation needs caution if you have kidney disease, heart failure, or take medications affecting potassium including some blood pressure drugs — excess potassium is genuinely dangerous. Check with a clinician.
Will it help with GLP-1 fatigue?
It may, if inadequate fluid and electrolytes are the cause, which is common early on. If fatigue persists despite good hydration, that warrants discussing with your prescriber rather than adding more supplements.
Considering Buoy?
If you have kidney disease, heart failure, or take medication affecting potassium, check with a clinician before adding an electrolyte supplement.
