Electrolytes and Hydration for GLP-1 Users
Look for an electrolyte product supplying roughly 500–1000 mg sodium, 200–400 mg potassium, and 60–100 mg magnesium per serving, with little or no added sugar. On a GLP-1, one serving daily — two on injection day or in heat — covers most people.
About 20% of daily fluid intake normally comes from food. On a GLP-1 you are eating far less food, your thirst signalling is blunted, and any nausea or loose stools pull more fluid out. Mild dehydration becomes the default state rather than the exception.
That matters because a lot of the symptoms people blame on the medication — headaches, dizziness on standing, fatigue, muscle cramps, brain fog, worse constipation — are classic mild dehydration and electrolyte depletion.
- Target ratios: sodium, potassium, and magnesium per serving
- Why plain water alone can make symptoms worse
- When to take electrolytes — injection day, heat, and training
- What to avoid: high sugar, sugar alcohols, mega-dose caffeine blends
What to look for on the label
- Sodium 500–1000 mg per serving — the mineral that actually holds fluid in circulation
- Potassium 200–400 mg — works with sodium for cellular fluid balance and cramp prevention
- Magnesium 60–100 mg — supports muscle function and gut motility
- Little to no added sugar — you don't need the carbohydrate load
- No large sugar-alcohol content — sorbitol and similar can worsen bloating and loose stools on a slowed gut
Why water alone isn't enough
Drinking large volumes of plain water while eating very little food dilutes the sodium you do have. That can leave you feeling worse rather than better — more lightheaded, more fatigued, and needing the bathroom constantly without feeling hydrated.
Electrolytes are what allow the water you drink to stay where it is useful. This is why people often report that their first electrolyte serving fixes a headache that two litres of water didn't touch.
When to take them
- Daily baseline: one serving, usually mid-morning
- Injection day and the 48 hours after: this is when appetite and intake drop hardest
- Hot weather or any sweating exercise: add a second serving
- During a nausea or loose-stool episode: sip an electrolyte drink rather than plain water
- If you feel dizzy standing up: that's a fluid-volume signal, not just low blood sugar
Hydration and creatine
If you're taking creatine to protect muscle, hydration matters more, not less — creatine draws water into muscle tissue. Pairing creatine with an electrolyte source is the simplest way to keep that working in your favour rather than leaving you feeling flat.
Shop hydration and electrolytes
Start with a daily electrolyte serving. Add creatine hydration if you're training, and evening magnesium if constipation or cramping is part of the picture.
