Electrolytes: The Hidden Powerhouses of Your Body
Electrolytes keep fluid balance, nerves, and muscle contraction working—especially when you sweat hard.
Sodium, potassium, calcium, magnesium, chloride, and related ions keep your electrical systems online. Athletes notice them most when sessions are long, hot, or salty-sweat heavy. This page educates— it does not diagnose imbalance.

The Quick Answer
Replace fluid and sodium to match your sweat. Use food and sport drinks thoughtfully. Serious symptoms (confusion, extreme weakness, irregular heartbeat) need medical care—not another packet of powder.
Intake Chart (Original)
Reference chart from the original article. Confirm current recommendations with a professional.
The Main Players
- Sodium — fluid balance and the big sweat loss for many athletes
- Potassium — nerve and muscle function; plentiful in many foods
- Calcium — muscle contraction and bone health context
- Magnesium — muscle/nerve support; see dedicated guide
- Chloride & bicarbonate — acid–base and fluid context
When Balance Is Off
Imbalances can relate to dehydration, overhydration, cramps, heartbeat changes, blood-pressure shifts, or cognitive symptoms. That list is awareness—not a self-treatment chart. Get help for severe signs.

Frequently Asked Questions
What are electrolytes?
Minerals that carry charge in body fluids—commonly sodium, potassium, calcium, magnesium, chloride, and related ions.
Why do athletes care?
Sweat loses fluid and sodium especially. Replacing what you lose supports performance and how you feel in heat or long sessions.
Is water enough?
Sometimes. Long, hot, or very salty-sweat sessions often need sodium with fluid—not water alone in extreme cases.
Sodium first?
For many sweaty athletes, sodium is the priority electrolyte in sport drinks. Potassium and magnesium still matter in the overall diet.
Does RBST sell electrolytes?
No. Education only.
Cramps equal low electrolytes?
Not always. Fitness, pacing, and fatigue also matter. Do not self-diagnose from cramps alone.
Natural food sources?
Salty foods, fruit, dairy, leafy greens, and balanced meals help. See our natural replenish article for ideas.
Hyponatremia risk?
Overdrinking plain water in ultra-long efforts can be dangerous. Match fluid to sweat and include sodium when appropriate.
Chart on this page?
We keep the original intake chart image as a visual reference—verify numbers with current public guidance and your clinician.
Kids/medical conditions?
Professional care—especially kidney, heart, or blood-pressure issues.
HYROX/CrossFit tip?
Practice your race-day drink in training. Do not debut a new formula on test day.
