As doctors assure, a person is not recommended to use more than 100-200 mg of caffeine at a time and not more than 1000 mg per day. Otherwise, there may be problems with the cardiovascular system. It is
easy to calculate the amount of caffeine used, but note that the figure is not accurate. For example, black tea contains 40 mg of caffeine per 100 ml of drink, green – 20 mg per 100 ml, red – 30 mg per 100 ml, and tea with interesting name Oolong – 25 mg of invigorating substance per 100 ml of boiling water .
Of course, drinking the amount of drink that will exceed all allowable norms for caffeine content is simply unrealistic. For comparison, brewed coffee contains 60 mg of caffeine per 100 ml, and soluble slightly less — 45 mg.
Pregnant and lactating women, as well as those who periodically increase blood pressure, white tea will be optimal. It contains a minimum dose of caffeine, which is just 5mg per 100ml of the drink. This variety of tea has a wonderful taste and an unforgettable aroma.
People who are not recommended to drink drinks containing caffeine will be suitable for herbal or fruit tea – they do not contain a gram of tonic substance. But they are just as perfectly thirst quenching and energizing as black or green tea. It’s related to the presence of vitamins.
Consult a therapist if you doubt whether you can drink tea. After examination, the specialist will give the exact answer Well, you will only stick to the general recommendations.
