Featured Products
XOUltra
Feel Lighter and Brighter
XOULTRA is an extra-strength ketone supplement designed to elevate your body into a deeper state of ketosis—where fat becomes your primary fuel source, not sugar.
Formulated with a proprietary, no-sodium blend.
XOImmune
Elevate Your Ketosis
XOIMMUNE is designed to help the body consistently reach Adjustable Targeted Adjuvant Ketosis (ATAK)—a personalized approach to maintaining optimal ketone levels that align with each individual’s metabolic needs.
XOGenius
Extra Fuel for the Brain
When your body can’t access carbs, it turns to ketones—natural energy molecules that fuel the brain and body while supporting fat metabolism. This process, known as ketosis, promotes healing, energy balance, and metabolic repair.

cognitive performance.
Neuroprotection
BHB ketones have been shown
to reduce neuronal damage and
promote the growth and survival
of neurons.
Higher & Faster-Peak
Ketone Levels
The BHB acid combined in XO Ultra produces rapid and higher peak ketosis than BHB electrolytes alone.

BHB helps support synaptic
plasticity — which not only enhances memory formation, but reduces oxidative stress and inflammasomes
