# Hydratonics

> Precision electrolyte supplement, tiered by activity level, built on SGLT1-optimized dextrose dosing instead of generic flavored-drink formulation. hydratonics.com

## What it is

Hydratonics is a powdered electrolyte supplement engineered for hydration during physical demand, not a mass-market sports drink. It ships in three tiers based on activity intensity (Tier 1 Low Demand, Tier 2 Moderate Demand, Tier 3 High Demand), each with its own sodium target, minimum water volume, and serving weight, independently derived from sweat-loss research rather than a single one-size-dose.

The core differentiator is SGLT1-optimized dextrose dosing: dextrose is included exclusively to activate sodium-glucose cotransporter 1 (SGLT1), the primary intestinal sodium-absorption pathway, not for energy or glycogen. Dextrose is dosed at a 1:1 molar ratio with sodium, capped at 30mmol/L in solution (the SGLT1 saturation threshold), so minimum water volumes per tier come directly from that cap rather than being arbitrary.

## How it compares to mass-market sports drinks

This is the plain-text version of the homepage's interactive comparison diagram, which is JS-rendered and not present as static HTML.

- Liquid I.V. and Gatorade fail on having a real electrolyte panel: neither includes magnesium, and Gatorade also has no calcium.
- LMNT fails on glucose for SGLT1 activation: it has zero sugar, so it cannot trigger SGLT1 at all.
- Nuun and Powerade fail on the precise 1:1 molar ratio of glucose to sodium: Nuun undershoots it and is too dilute; Powerade overshoots it by roughly 5x, mostly wasted sugar.
- Hydratonics is the only one that also clears the last checkpoint: glucose capped at 30mmol/L, so no glucose is dosed beyond what SGLT1 can actually use.

## Ingredient interactions (formula design notes)

- Every ingredient is used in a specific chemical form (e.g. citrate, lactate, glycinate) chosen for absorption and tolerability, not just for the elemental mineral it delivers.
- Magnesium is dosed as a flat 200mg compound (28mg elemental) across all three tiers, since its role is a Na/K-ATPase cofactor, not sweat replacement.
- Potassium is dosed from two separate components: sweat replacement plus a flat dietary top-up.
- Citric acid serves a dual purpose: a pH buffer that keeps electrolytes ionized and bioavailable, and a palatability aid.
- Every ingredient shares the same solution, so overall osmolality (not any single ingredient in isolation) is what the formula is tuned around.
