LMNT Electrolytes
Sugar-free sodium-potassium-magnesium for fasting, keto, and training
LMNT is the biohacking community's default electrolyte drink: 1000mg sodium, 200mg potassium, 60mg magnesium per packet with zero sugar. Created by Robb Wolf, it's essential for intermittent fasting, keto, sauna sessions, and Zone 2 training where sweat losses demand aggressive sodium replacement.
Typical price: $45 USD / 30 packets

How It Works
Low-carb diets, fasting, and heavy sweating deplete sodium faster than standard dietary intake replaces. The 'keto flu,' fasting headaches, and post-sauna fatigue are primarily sodium deficiency — not magic. LMNT delivers therapeutic sodium doses (1000mg) that Gatorade (140mg) and most electrolyte products can't match without sugar.
Sodium Replacement
1000mg sodium per packet replaces losses from fasting, sweating, and low-carb diets.
Zero Sugar
No glucose — won't break a fast or spike blood sugar on a CGM.
Full Spectrum
Sodium, potassium, and magnesium in ratios optimized for biohackers, not mainstream sports drinks.
What You'll Experience

Fasting Support
Moderate EvidencePrevents headaches and fatigue during intermittent fasting and extended fasts.
Sodium Replacement
Strong Evidence1000mg sodium — 7× a Gatorade — for sauna, training, and keto losses.
CGM-Friendly
Strong EvidenceZero sugar means zero glucose impact on continuous glucose monitors.
Risks & Considerations
Blood Pressure
medium risk1000mg sodium per packet. Caution if hypertensive or on sodium restriction.
