There are big factors that define the difference. Our VitaliTea is grown in the high mountain regions of Vietnam where the soil is rich in volcanic ash, the humidity from the clouds is precise, and the altitude and temperature are distinctly defined. We only utilize the youngest buds from the plant because that is where the highest concentration of Antioxidants, Polyphenols, Vitamins and EGCG are found. VitaliTea is also preserved and packaged in a unique way that captures the highest amounts of nutrients possible. While all that is incredible the fact is VitaliTea is just the fist step in a three step system called AI³. This system increases the overall benefits of the VitaliTea over 50 fold.
