Just as there are many varieties of grapes for wine making, there are many varieties of goji—as many as 41 species growing in Tibet alone!

Freelife knew that they must exhaustively analyze the dozens of varieties to find the one true goji—the one that had been discovered by the early Himalayan healers, and Freelife's Himalayan Goji Juice is the only one that has the Spectral Signature!which, from ancient times, had been praised in legend.

In the same way that human fingerprints can be used to distinguish one person from all others on the planet, a spectrometer can detect even subtle differences between berries at the molecular level. This technique results in the generation of a graph; a unique fingerprint for whatever is being tested—a Spectral Signature.

Thanks to years of dedicated scientific research, FreeLife™ is the only company in the world to have developed a Spectral Signature to identify, isolate, and harvest only those special goji berries with the exact nutrient profile of the legendary goji from the Himalayas.
