Cadence Hydration Sachets
Product Description
The hydration system that separates the pros from everyone else.
When elite athletes need hydration that works as hard as they do, they reach for Cadence Core 500 and Race 500. This precision nutrition brand delivers what your body needs—nothing more, nothing less.
The Difference
Core 500 is your foundational hydration weapon.
Each serving delivers 500 mg sodium, 200 mg potassium and 20 mg marine magnesium in their most bioavailable forms. Zero carbs, zero caffeine—perfect for daily hydration, post-workout recovery, or anytime you need clean electrolyte replenishment.
Race 500 takes the same science-backed electrolyte profile and adds the mental edge: 200 mg L-theanine and 100 mg caffeine in a targeted 2:1 ratio.
This dual-action approach delivers smooth, sustained energy and laser focus without the jitters. The caffeine increases alertness while L-theanine calms the nervous system, keeping you cool and composed when performance matters most.
Why It Works
Sodium plays a pivotal role—it increases fluid absorption and retention, and maintains electrolyte balance. Research shows drinks containing sodium improve endurance, mood and reaction times while reducing cramps and hyponatremia. The marine magnesium supports over 300 enzymatic reactions, including those that produce ATP.
Usage
Mix one sachet with 500 ml-1 L of water. Use Core 500 anytime—especially effective first thing in the morning or after training. Use Race 500 30-60 minutes before high-intensity sessions.
Choose Core 500 for clean daily hydration. Choose Race 500 when you need hydration plus mental performance. We love this systematic approach to hydration.

Frequently asked questions
What is the Cadence Core 500 Sachet and what does it do?
Core 500 is a daily electrolyte sachet delivering 500mg sodium, 200mg potassium, and 20mg marine magnesium per serving. It's designed to restore the minerals your body loses through sweat, support cellular hydration, and keep your energy and focus sharp throughout the day — without any sugar, carbs, or caffeine.
When should I take the Cadence Core 500 Sachet?
Core 500 can be used any time of day. Most athletes find it most effective first thing in the morning — when you're naturally most dehydrated after sleep — and again around training, either 30 minutes before, during, or immediately after high-intensity sessions. On harder training days or in hot conditions, you can take up to 3–4 sachets throughout the day.
What's the difference between Core 500 and Race 500?
Core 500 is your clean, caffeine-free daily hydration option — perfect for any time of day including evenings and rest days. Race 500 uses the same electrolyte profile but adds 100mg caffeine and 200mg L-theanine for pre-workout energy and mental focus. Use Core 500 as your everyday foundation and Race 500 when you need a performance edge before hard sessions.
Why does Core 500 use such a high sodium dose?
Sodium is the most important electrolyte for hydration, and it's the one most sports drinks dramatically under-deliver on. At 500mg per serving, Core 500 hits the threshold shown in research to meaningfully improve fluid absorption, increase fluid retention, and prevent the performance drops that come from electrolyte imbalance. Most electrolyte products give you a fraction of that.
Is Core 500 safe to use every day?
Yes — Core 500 is designed specifically for daily use. Individual electrolyte needs vary based on your sweat rate, training intensity, and environmental conditions. Cadence recommends a food-first approach to electrolytes and suggests consulting your doctor for specific guidance on daily sodium intake, especially if you have any pre-existing health conditions.
