Sodium (Electrolyte)
Also known as: Salt, Sodium chloride
Sodium is an essential electrolyte central to fluid balance and nerve and muscle function. Most people get ample sodium from food, but it is discussed as an electrolyte to replace during prolonged, heavy sweating such as endurance exercise or hot-weather activity. Any decision to add sodium should account for the well-known relationship between sodium intake and blood pressure, and is best interpreted cautiously and individually.

What this page can tell you: Commonly discussed timing, food notes, caution categories, and an honest note on how much source review this entry still needs.
What it cannot: Whether this is appropriate for you personally, or that it treats, prevents, or cures any condition. Informational only — discuss with a clinician or pharmacist.
🕒 Timing
When: With a meal, Anytime
Food: With or without food
In fitness contexts, commonly taken around prolonged or heavy-sweat activity.
💊 Common use range
Highly individual mg
Needs vary widely with sweat losses and diet; most people already get plenty from food — verify and consider blood-pressure guidance.
Ranges are informational, not a recommended dose. Talk to a professional about what is right for you.
⚠️ Commonly noted interactions (supplements)
None listed.
Often about absorption or timing rather than danger — separating doses is common. This list is not exhaustive.
🧭 Caution level
- Electrolyte balance — higher caution with kidney or heart conditions
- Higher caution if you take blood-pressure medication
- Higher caution if you have a heart condition or take heart medication
- Higher caution if you have kidney disease
- Evidence not fully source-reviewed yet
Caution level is an informational summary of commonly discussed caution categories and doses — not a safety rating, approval, or medical advice. Low caution does not mean safe for you.
🩺 Medication caution categories
- Blood pressure medication
- Heart conditions or heart medication (health condition)
- Kidney disease (health condition)
🏥 Surgery & procedure caution
Not a well-established surgical concern; share your full supplement list with your care team.
If you have a procedure scheduled, bring your full supplement list to your surgical and anesthesia team. Do not stop prescribed medication unless your clinician tells you to. Do not start or stop supplements based only on this app.
