8 sticks, two CORE and six FUEL across every flavor.
Why there are two
Your cells need different things in two different states: your daily state and your sweat state. SRC is two products because hydration is step one of healthy cells, and the electrolytes you need depend on how your day looks.
CORE · Every day
Nine actives with the strongest longevity research behind them, including 5g creatine and NMN, on a potassium-forward base for everyday hydration. One stick every morning.
3:1 potassium to sodium
FUEL · When you sweat
Sodium-forward with coconut water carbs that speed absorption, because sweat is mostly salt and you want it back fast. For workouts, heat, travel, or a day you barely ate.
3:1 sodium to potassium

What's inside CORE
We left out more than twenty ingredients because the research wasn't conclusive enough.
Fast energy for muscles and brain. The dose the research uses. No loading phase, and no bloat: any early water shift happens inside the muscle, where you want it.
Your body converts it into NAD+, which your cells run on for energy and repair. NAD+ falls as you age. 300mg is in the range used in human trials.
Your mitochondria use it at the step where food becomes usable energy. Your body makes less of it every decade.
Works alongside CoQ10 and supports how your cells produce energy.
A plant compound that supports a healthy inflammatory response. The human research uses about 500mg.
An amino acid from tea. Supports focus and a calm, alert state.
Absorbed well, easy on your stomach.
The daily essentials at sensible amounts.
450mg potassium, 150mg sodium, 150mg magnesium. Sodium from pink Himalayan sea salt, potassium mostly from organic coconut water.
What's inside FUEL

From pink Himalayan sea salt.
