## Direct answer

The best electrolyte option on a GLP-1 delivers roughly 500–1,000 mg sodium, 200–400 mg potassium, and 60–120 mg magnesium per serving with little or no sugar. Unflavored powders and low-sugar sticks meet that profile; conventional sports drinks and coconut water do not carry enough sodium for the amounts most GLP-1 users need.

- Target 2,000–4,000 mg sodium daily from all sources, more if you sweat
- Sugar-free is not automatically better — sugar alcohols can worsen GI symptoms
- One serving in the morning, a second mid-afternoon covers most people
- Magnesium in a drink mix rarely reaches a full nightly dose on its own

## Electrolyte formats side by side

Amounts are per typical serving. Check your own label — sodium content varies by an order of magnitude between products.

| Option | Best for | Typical daily amount | What to know |
| --- | --- | --- | --- |
| Low-sugar electrolyte powder or stick | Daily use on a GLP-1 | 1–2 servings daily | Best match for GLP-1 needs when sodium is 500 mg or higher per serving. Watch for sugar alcohols if you are prone to bloating. |
| Conventional sports drink | Endurance exercise, not daily hydration | Occasional | Typically 100–200 mg sodium and 20–35 g sugar per bottle — too little sodium and too much sugar for daily use with a suppressed appetite. |
| Coconut water | Potassium top-up | 1 cup | Good potassium, very low sodium. Useful as a supporting drink, not as the primary electrolyte source. |
| Salt in water (or salted broth) | Cheap sodium replacement | 1/4 tsp salt ≈ 575 mg sodium | Effective and inexpensive. Provides no potassium or magnesium, and broth is often easier to tolerate than salted water. |
| Electrolyte tablets | Travel and gym bags | 1–2 tablets | Convenient but usually lower in sodium than powders. Read the label before assuming one tablet replaces a full serving. |
| Standalone magnesium supplement | Night cramps and sleep | 200–400 mg glycinate at night | Separate from your daytime electrolyte drink. Drink mixes rarely contain enough magnesium to cover the evening dose. |

Thirst cues are blunted on a GLP-1, food volume is smaller, and food is where most people get their sodium and potassium. That combination produces the classic pattern of afternoon fatigue, lightheadedness on standing, and night cramps.

This comparison covers the formats people actually reach for, what each delivers, and where each falls short.

## How much sodium you actually need

Most adults on a GLP-1 do well between 2,000 and 4,000 mg of sodium per day from all sources, and more when sweating heavily. Low sodium — rather than low water — is behind most of the lightheadedness and afternoon fatigue people describe. If you have high blood pressure, heart failure, or kidney disease, set the target with your clinician instead of following a general range.

## Ingredients to avoid

- 20 g or more of sugar per serving, which crowds out food you need for protein
- Sugar alcohols such as sorbitol and maltitol, which commonly worsen bloating and loose stools
- Caffeine or other stimulants stacked into a hydration product
- Magnesium oxide, which absorbs poorly compared with glycinate or citrate

## When to drink them

- First serving with your morning water, before coffee
- Second serving mid-afternoon, when the fatigue dip usually lands
- An extra serving on hot days, training days, and the 48 hours after a dose increase
- Aim for roughly half your body weight in ounces of total fluid daily

## FAQ

### Are electrolytes necessary on Ozempic or Wegovy?

For most people, yes — at least during titration. Smaller meals mean less dietary sodium and potassium, and blunted thirst means less fluid. Adding one to two servings a day resolves a large share of reported fatigue and cramping.

### Can I just drink more water?

Water alone can make things worse by diluting sodium further. Fluid and sodium need to move together, which is what an electrolyte serving does.

### Should I take electrolytes on injection day?

Yes, and the two to three days after a dose increase are usually when the need peaks, because nausea and lower intake compound the shortfall.

### Is there a downside to too much sodium?

Yes for people with hypertension, heart failure, or kidney disease. Those conditions call for a clinician-set target rather than a general recommendation.
