L-theanine, an amino acid found in green tea, produces a pronounced feeling of tranquility in as little as fifteen (15) minutes. L-theanine increases the activity of GABA, a neurotransmitter (i.e. natural messenger in the brain) that promotes relaxation and reduces anxiety. L-theanine also stimulates the release of dopamine, a neurotransmitter responsible for confidence and a sense of well-being.
SEREDYN contains SunTheanine® brand L-theanine, the purest and most potent L-theanine available. Many other formulas sold as "L-theanine" actually contain green tea extract, not pure SunTheanine® brand L-theanine. As a result, these products provide only a small, ineffective dose of L-theanine and usually contain other compounds, including caffeine, that may actually increase anxiety. Only formulas containing pure L-theanine, such as SEREDYN, will effectively calm your nerves.
