Electrolytes & Creatine: What They Actually Do For Your Body
Two ingredient categories, one clear job: help your body hold onto water, fire your muscles, and recover faster. Here's what the research actually says about sodium, potassium, and creatine monohydrate.
Sodium
Sodium is the electrolyte your body loses the most of when you sweat — and the one most sports drinks meaningfully underdose. It's the mineral primarily responsible for keeping fluid where your body actually needs it: inside your cells and blood vessels, not just passing through you.
- Helps your body actually retain the water you drink, instead of losing it straight to urination
- Supports nerve signaling and muscle contraction, which is why low sodium is linked to cramping
- Sweat sodium losses vary widely person to person — some people lose far more per hour of activity than a typical sports drink replaces
Because plain water dilutes blood sodium during heavy sweating, replacing electrolytes — not just fluid — is what actually restores balance. A controlled study comparing water, a standard sports drink, and a higher-electrolyte rehydration solution found the higher-sodium option produced better post-exercise fluid retention.

If sodium controls where fluid goes, potassium is sodium's partner inside the cell — the two work as a pair. Most sports drinks skip potassium almost entirely, or add a token amount.
- Works alongside sodium to regulate fluid balance across your cell membranes
- Plays a role in how muscles store the carbohydrate they use as fuel during activity
- Commonly under-consumed in a typical American diet, especially by people who train or sweat regularly
Electrolyte balance research consistently frames sodium and potassium together, not separately — both are described as essential to fluid balance, nerve function, and muscle function during and after exercise.

Creatine is one of the most studied supplement ingredients that exists, with decades of research behind it. It's not just a bodybuilding ingredient — it's increasingly studied for recovery, performance, and cognitive function in everyday, active adults.
- Supports muscle strength, power output, and recovery after intense activity
- Being studied for its role in cognitive performance — memory, focus, and processing speed, especially under fatigue
- 5g is a full, standard maintenance dose — not a diluted or marketing-sized amount
A randomized, placebo-controlled crossover trial found that a week of creatine monohydrate supplementation improved cognitive performance, increased physical output during high-intensity exercise, and reduced muscle soreness. Separately, a systematic review found reductions in exercise-induced muscle damage markers alongside improved strength retention in supplemented groups.

Why 0g Added Sugar Actually Matters
Most electrolyte and hydration products lean on sugar for flavor — some carry 15–20g or more per serving. Mike's Electrolytes was built the opposite way: full clinical doses of the minerals that actually do the work, with none of the added sugar load. You get the hydration and performance support without the extra calories, the crash, or undoing what you're drinking it for in the first place.
Why We Built This Together
Mike's Electrolytes is a joint formula from Longevity Farms and Mike Glover — founder of Long Haul Supply Company and a longtime friend of Longevity Farms co-founder Joe Linares. Below, Joe and Mike break down why electrolytes and creatine, why now, and what this product means to both of them.
