Electrolyte depletion is very common on GLP-1 medications for several reasons: reduced food intake means reduced mineral intake, the medications can cause increased urination in some people, and if you're experiencing any vomiting or diarrhea, you're losing electrolytes directly.
The three key electrolytes to focus on:
Sodium: 2000-3000mg/day total (from food + supplements). Most people on GLP-1 are actually UNDER on sodium because they're eating less processed food. Yes, you read that right — you might need MORE salt, not less.
Potassium: 3500-4700mg/day. Hard to get from supplements alone (most supplements are capped at 99mg per serving for safety). Focus on food sources: avocado, banana, potato, coconut water.
Magnesium: 400-420mg/day for men, 310-320mg for women. Magnesium glycinate is the best-absorbed form and least likely to cause GI issues. Take before bed — it also helps with sleep.
Product recommendations:
- LMNT — Best overall electrolyte packet. 1000mg sodium, 200mg potassium, 60mg magnesium. No sugar. Tastes good. Pricey.
- Drip Drop ORS — Medical-grade oral rehydration. Good for days with nausea/vomiting.
- DIY Option: 1/4 tsp salt + 1/4 tsp NoSalt (potassium chloride) + squeeze of lemon in 500ml water. Costs pennies.
For the cramps specifically — the magnesium supplement before bed will likely resolve those within a week.
