There are only 5 places on Earth called Blue Zones — regions where people consistently live past 100 years old. Researchers have been studying them for decades trying to figure out why.

One of those places is the Nicoya Peninsula in Costa Rica. And one of the most consistent findings? The water.

The volcanic bedrock in Nicoya naturally mineralizes the groundwater with high concentrations of calcium and magnesium. Studies have shown the people there have some of the lowest rates of heart disease and strongest bone density on the planet — and the water composition is always flagged as a contributing factor.

We bottle that water at the source. Premium glass, sealed on-site, shipped direct.

Not filtered city water with minerals added back in. Not "spring water" from some corporate facility. The actual water from one of the most extraordinary geological formations on Earth.

That's BLU.
