Green Tea X-tract is a great product so far so good. Has given me a boost in energy without that jittery feeling when you drink too much coffee. I have heard that green tea is also good for weight loss. So far it seems like it is helping me all over. I have lost 4. 5 pounds so far.It does seems to be helping me be more mentally focus as well. This green tea has Vitamin C that is packed with natural antioxidants , it will help boost the immune system and I sure need help with that. My immune system needs to be boosted big time so I will take that. Also helps with free radicals and it is loaded with polyphenols to fend off diseases. These have no caffeine in them and are made in USA, which I like we need more companies to make their products in the USA.
