Whether you're sprinting to the finish,

Staying competitive through the final set,

Or reaching that mountain top,

It started in our kitchen, with a mixer and an idea.

Using real ingredients, we combined what's found in nature with decades of sport-science research to improve endurance.

We're Endurance Experts.

We tested each version ourselves, then with our friends - from professional triathletes to firefighters.
We spent over 18 months refining each ingredient's source, concentration, and performance contribution. Finally, we achieved a product to be proud of: a product that enables people to work harder, longer.  

 If you're eager to push your boundaries, then Sword is for you.
