What is Gaba? It is gamma-aminobutyric acid (GABA). It is responsible for attention and work performance. In the late 1980s, the Japanese developed a technology for processing tea leaves without oxygen, which increased the content of GABA. This is how Gaba appeared! Nowadays, it is trendy and has a mild and dense taste with natural hints of fruits, flowers, berries or chocolate and a delicate, sweet fragrance. It relaxes the body and helps to concentrate the mind.
