What is thein?

How does the body react to the effects of the theine?

The action of theine includes stimulation of the central nervous system, which translates into greater alertness and better concentration.

Is thein harmful? 

This question comes up often, as the reaction to stimulants can be very individual. For most adults, moderate amounts of theine are safe, but it is worth paying attention to the signals sent by the body, especially when prone to insomnia, palpitations or feelings of anxiety.
