So for all the above groups who don't want to give up their tea break, tea without theine is the solution. Finally, people with heart or stomach problems may be advised to remove theine from their diet. Also children, whose lower bodyweight increases the theine concentration in their body, and also slows its elimination. Doctors generally recommend that they reduce their consumption to two cups of tea per day.

Another group that could seek to reduce their theine consumption is that of pregnant women. The stimulation felt, the rate of absorption of theine, and the tolerance is specific to each person. This is the case for people sensitive to theine, who worry they will have trouble falling asleep. While the stimulating and energising effect of tea is sought after for its considered benefits, others may wish to avoid this effect. There are also great disparities between the different types of tea : black tea is the richest in theine (in particular because it releases it more quickly), ahead of green tea and white tea, reputed to be the "lightest". The theine found in tea leaves is released when they are immersed in hot water. Just enough to stay awake and alert when meditating, say some Buddhist monks. This explains the reason why coffee has an exciting effect, while tea has simply a stimulating effect. The difference between the world's two most consumed hot drinks is that coffee contains much more: three to four times more than in a cup of tea. While thought to be different for a time, theine and caffeine is one and the same molecule.
