What Should I Include as “Electrolytes” in a First Aid Kit?

Question: What do you recommend including in an outdoors or wilderness first aid kit as “electrolytes”? Is salt alone sufficient, or should I take a variety of electrolyte sources?

Survival Med’s Answer: While sodium is a primary electrolyte, it’s beneficial to have a balanced mix. Here are some options to consider:

1. Oral Rehydration Salts: These packets or tablets create a solution with a balanced mix of electrolytes when dissolved in water.
2. Electrolyte Replacement Drink Mixes: Commercially available powder mixes offer a blend of electrolytes and can be added to water. They often come in single-serving packets for convenience.
3. Sports Drinks: Include small bottles of sports drinks designed to replenish fluids and electrolytes during physical activity or dehydration situations.
4. Salt Packets: Individual salt packets, like those from fast-food places, can be added to food or beverages for increased sodium intake.
5. Magnesium Supplements: In specific situations, such as prolonged exertion, magnesium supplements may help replenish levels. Consult with a healthcare professional for personalized advice.
6. Calcium Supplements: Similar to magnesium, consider calcium supplements based on individual needs and in consultation with a healthcare professional. Over-the-counter levels are generally safe, with excess calcium excreted in urine.
