Teas enriched in GABA are consumed for their beneficial effects on blood pressure, stress and anxiety. These effects may involve actions of GABA on the central and peripheral nervous systems. The anaerobic procedures for the production of GABA-enriched teas increase GABA levels by 10–20 times. They also significantly alter the levels of other constituents that may interact with the actions of GABA. These include epigallocatechin gallate, caffeine and theanine. The possible interactions of these active constituents make the understanding of the effects of GABA-enriched teas complex. More data is needed to establish where and how GABA is acting following consumption of GABA-enriched teas. While there is considerable evidence that such GABA is acting on GABA receptors in the periphery, there is rather less evidence that is acting directly in the brain. Certainly, there is more to the action of GABA-enriched teas than GABA itself.

富含 GABA 的茶因其对血压、压力和焦虑的有益作用而被食用。这些影响可能涉及 GABA 对中枢和外周神经系统的作用。生产富含 GABA 的茶的厌氧程序将 GABA 水平提高了 10-20 倍。它们还显着改变了可能与 GABA 作用相互作用的其他成分的水平。这些包括表没食子儿茶素没食子酸酯、咖啡因和茶氨酸。这些活性成分之间可能的相互作用使人们能够了解富含 GABA 的茶的影响。需要更多的数据来确定在食用富含 GABA 的茶后 GABA 在何处以及如何起作用。虽然有相当多的证据表明这种 GABA 作用于外周的 GABA 受体，直接作用于大脑的证据较少。当然，富含 GABA 的茶的作用不仅仅是 GABA 本身。
