Electrolyte Supplement

You lose electrolytes when you sweat. This replaces them exactly.

Calibrated to your output. Nothing added. Nothing missing.

Most electrolyte products guess at dosing. Every ingredient here has a specific reason to be here, and a specific reason it is dosed the way it is. The formula does not include anything that is not working.

Three Tiers

Sweat loss is not the same at every intensity.

A single formula cannot serve a 45-minute strength session and a three-hour marathon. The electrolyte demand is fundamentally different. Each tier is calibrated to a specific output level, not to a marketing narrative.

The Formula — Tier I

Every ingredient has a job. Nothing else is here.

Sodium is the anchor. Everything else exists in relation to it, calculated from sweat research, not chosen for a label. Here is exactly what is in Tier I and why.

Ingredient Amount Why it's here
Sodium Chloride 1,017 mg Primary sweat electrolyte. 400 mg elemental sodium, validated against ACSM sweat research. Pre-exercise sodium improves fluid retention going into the session.
Dextrose Monohydrate 3,448 mg Not for energy. Not for glycogen. It activates SGLT1, the sodium-glucose co-transporter in the gut that moves sodium across the intestinal wall. Without glucose, this absorption pathway is significantly impaired. Dosed at a 1:1 molar ratio with sodium, capped at the SGLT1 saturation threshold. Every gram is doing work.
Potassium Citrate 606 mg Two components: sweat replacement proportional to output, plus a flat 150 mg correction for the chronic dietary deficit most people carry. Low potassium impairs the Na/K-ATPase pump that processes the sodium you absorb. Citrate form chosen over KCl for its alkalinizing effect and better tolerability.
Calcium Lactate 201 mg Sweat replacement at 1.5x the literature sweat concentration. The buffer accounts for individual sweat rate variability. Lactate form for superior bioavailability.
Magnesium Glycinate 200 mg Not sweat replacement — sweat magnesium loss is trivial. This is a flat functional dose to support Na/K-ATPase activity. Magnesium is a hard biochemical requirement at the enzyme's catalytic site. Without it, the sodium and potassium this formula delivers cannot be properly processed across cell membranes. Glycinate form for approximately 80% bioavailability and minimal GI impact.
Citric Acid 480 mg pH buffer and palatability agent. Masks the metallic notes from potassium citrate and magnesium glycinate. The only ingredient here primarily for taste, and it earns its place functionally.
Silicon Dioxide 48 mg Anti-caking agent. 0.8% of total serving mass. No electrolyte function.

The question everyone asks

Why is there sugar in this?

The short answer

The dextrose is not for energy or calories. It is the key that unlocks the most efficient sodium absorption pathway in your gut. Without it, a significant portion of the sodium passes through unabsorbed.

Your small intestine has a protein called SGLT1, the sodium-glucose co-transporter. It moves sodium and glucose together across the intestinal wall, co-transporting two sodium ions per glucose molecule. This is the same mechanism that oral rehydration solutions have used for decades to treat dehydration in clinical settings.

Without luminal glucose, this pathway operates at a fraction of its capacity. Sodium can still be absorbed through other mechanisms, but the efficiency drops substantially.

The dextrose in this formula is dosed at a 1:1 molar ratio with sodium, the ORS evidence-based target. It is also capped at the SGLT1 saturation point in solution, which sets the minimum water volume for each tier. Beyond that threshold, additional glucose does not improve absorption. Every gram of dextrose here is activating the pathway, not adding unnecessary sugar.

The formula delivers 12.5 calories per serving. That is not a meaningful energy contribution. It is the cost of optimal hydration.

How this is different

Why not just use LMNT, Liquid IV, or Nuun?

LMNT has strong sodium dosing but no dextrose. The SGLT1 pathway is never activated. The sodium is absorbed, but not as efficiently as it could be.

Liquid IV uses the ORS glucose mechanism but doses sugar far beyond the SGLT1 saturation threshold. The excess glucose is absorbed as calories, not as a transport mechanism. It also adds B vitamins, vitamin C, and other ingredients not justified by the hydration function.

Nuun uses very small glucose doses that likely do not sustain SGLT1 activation throughout consumption. The electrolyte amounts are also lower than most active people need.

This is the only product in the consumer market designed explicitly around the SGLT1 saturation ceiling. Enough glucose to fully activate the pathway, not more than that, combined with sodium amounts validated against published sweat research. Three tiers because the demand is different at different intensities, not because the branding needed variety.
