Description
The SF1 Yin & Yang Bundle includes two powdered electrolyte formulas designed to support hydration across both daily life and high-output activity. It delivers Complete, Adaptive Hydration — One System, Two States. Yin supports steady daily mineral balance and recovery rhythm, while Yang supports electrolyte replenishment during intense training, heavy sweat loss, and demanding conditions. Together they provide a structured hydration system built to match the body’s changing output, rather than forcing one formula to do everything.

Complete Adaptive Hydration System
SF1 Yin & Yang is a two-formula electrolyte system designed to support hydration across the full cycle of daily life and high physical output.
Most hydration products use a single formula for every situation.
SF1 takes a different approach.
The body operates in two primary states:
Daily stability and recovery
High output and heavy depletion
The SF1 Bundle provides both formulas, allowing hydration to match the demands placed on the body.
What’s Included
SF1 Yin — Daily Mineral Hydration
Supports steady hydration during:
• work days
• study blocks
• travel
• rest days
• recovery periods
• light to moderate training
Designed to support consistent mineral balance and cognitive clarity throughout the day.
SF1 Yang — High Output Electrolytes
Designed for periods of high exertion and heavy sweat loss, including:
• intense training
• endurance sports
• CrossFit and functional fitness
• matches and competitions
• long rides and runs
• hot environments or sauna
Supports electrolyte replenishment when mineral loss increases.
The SF1 Mineral Blueprint
Both formulas are built around four core electrolyte components that support hydration and electrical signalling in the body:
• Potassium Gluconate — intracellular hydration and nerve signalling
• Magnesium Taurate — neuromuscular balance and recovery support
• Sodium (Himalayan Rock Salt) — fluid balance and sweat replacement
• Camu-Camu (Vitamin C) — antioxidant and metabolic support
These ingredients form the SF1 Mineral Blueprint, designed to support hydration structure rather than simply fluid intake.
Why the Bundle
Hydration needs change depending on activity level, stress load, and sweat loss.
The bundle allows you to use:
Yin — for daily mineral balance
Yang — when output rises
Simple. Flexible. Structured.
What You Won’t Find
• No sugar
• No stimulants
• No artificial energy spikes
• No crash cycles
Just structured mineral hydration designed to support sustained output.
