Why there are two

What your cells need depends on the day.

FUEL is for when you sweat. CORE is your daily foundation. The electrolytes you need depend on how your day looks, so SRC is two products.

CORE · Every morning

Targets the root causes of aging at the cellular level.

Creatine, antioxidants, NAD+ support, and electrolytes. Most of it you're probably not taking yet. One stick, every morning.

FUEL · When you sweat

Water isn't enough when you sweat.

FUEL hydrates your cells fast, with coconut water, pink Himalayan sea salt, and no added sugar or artificial sweeteners.
