LMNT delivers 1,000mg of sodium, 200mg of potassium and 60mg of magnesium per serving with zero sugar, a deliberately high dose with published reasoning behind it.
Overview
LMNT is an electrolyte drink mix built on a specific and unusual ratio: 1,000mg of sodium, 200mg of potassium and 60mg of magnesium per serving, with zero sugar. That sodium figure is the defining feature and is several times what conventional sports drinks contain. The company publishes detailed explanations of why it chose those doses rather than simply asserting them, which is more than most competitors do.
LMNT also operates a science arm that has published specifically on GLP-1 medications and electrolytes, examining how the two interact through hydration, appetite and side effects. That is a genuine connection rather than a marketing stretch. GLP-1 medications reduce food intake, and food is a major source of both fluid and sodium. Add the nausea, vomiting and altered bowel habits that many users experience, and the result is a meaningful risk of dehydration and electrolyte depletion. Fatigue, dizziness and muscle cramps follow, and they are routinely blamed on the medication when the immediate cause is a fluid and electrolyte deficit.
The dose that makes it useful also makes it inappropriate for some people. A gram of sodium per serving is far more than a sedentary person with normal food intake needs, and it is straightforwardly contraindicated for anyone on a sodium-restricted diet for hypertension, heart failure or kidney disease. LMNT is upfront about its reasoning, which puts the responsibility on the buyer to know whether they are the right buyer.

What Is Actually in It
- 1,000mg of sodium per serving, deliberately high
- 200mg of potassium and 60mg of magnesium
- Zero sugar in every version
- An unflavoured option for people who dislike stevia
- Stick pack format suited to travel
- Published scientific reasoning for the formulation
Supplement or Medication?
A dietary supplement, and a purely nutritional one. Electrolytes replace what fluid loss removes. Nothing here acts on GLP-1 or appetite, and LMNT's own content is explicit that it addresses the side effect rather than the treatment.
How You Buy It
Check whether the sodium dose suits you
1,000mg is right for some people and wrong for others.
Buy direct or at retail
Widely available through LMNT and third-party retailers.
Mix one stick pack
Into water, at the volume the pack specifies.
Use it when symptoms appear
Fatigue, dizziness and cramps are the signals it addresses.
Who It Is Sold To
- Adults on GLP-1 medication with fatigue, dizziness or cramps
- No consultation or clinical assessment involved
- Unsuitable if you are on a sodium-restricted diet
- Not appropriate for people with hypertension without clinical advice
- Excessive for a sedentary person with normal food intake
- Speak to a clinician if you have heart or kidney disease
Clinical Oversight and Evidence
Clinical Oversight
None, and this is one product where that matters. A gram of sodium per serving is a genuine clinical consideration for anyone with hypertension, heart failure or kidney disease, and those people should not take it without advice.
Evidence
LMNT publishes detailed reasoning for its ratios and its science arm has written specifically about GLP-1s and electrolytes. The underlying case, that reduced intake plus gastrointestinal losses on GLP-1 medication creates dehydration and electrolyte depletion risk, is well recognised. There is no trial of LMNT specifically in GLP-1 users.

- You are losing significant fluid through nausea or altered bowels
- You are getting dizziness, cramps or fatigue on a GLP-1
- You are active and sweating alongside your medication

- More expensive per serving than liquid alternatives
- Does nothing for appetite, nutrients or muscle
- The dose demands that you know your own clinical situation

Frequently Asked Questions
Why does LMNT contain so much sodium?
It is a deliberate formulation choice, and the company publishes detailed reasoning for the 1,000mg dose rather than simply asserting it. It is aimed at people losing significant fluid and sodium.
Is that safe?
For most active people with normal blood pressure, yes. It is not appropriate if you are on a sodium-restricted diet for hypertension, heart failure or kidney disease, and those people should speak to a clinician first.
Why do GLP-1 users need electrolytes?
Reduced food intake means less fluid and less sodium, and nausea, vomiting and altered bowel habits add further losses. The resulting fatigue, dizziness and cramps are often blamed on the medication when the immediate cause is a fluid and electrolyte deficit.
What is in a serving?
1,000mg of sodium, 200mg of potassium and 60mg of magnesium, with zero sugar.
Does it contain sweeteners?
The flavoured versions use stevia. An unflavoured version is available for people who dislike it.
How does it compare to Buoy?
LMNT provides far more sodium per serving and comes in travel-friendly stick packs. Buoy is flavourless, cheaper at around 25 cents a serving, and adds to any drink.
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.
