Caffeine Teas – The Little Tea Boutique

Caffeine Teas

We believe Tea is one of the healthiest beverage you can drink on a daily
basis. There are several types of teas that have caffeine in them. Caffeine level in tea can be affected by many factors like brewing method, parts of the tea plant, fermentation and roasting procedure, and finally the kind of tea. On my previous job, I personally rely on caffeine based drinks as I need to keep active an awake during a graveyard shift. I did that for many many years and I realize that too much caffeine is not really good for our body.

On the other hand, caffeine has a positive effect on our body as well. It will make you energetic, stimulate metabolism and help weight loss. After drinking tea, caffeine usually reaches our brain through the blood within ten minutes, thus it makes people feel refresh and active. Caffeine directly stimulates the colon muscles, which promotes bowel movements. At the same time, caffeine also stimulates the gallbladder muscles and reduces the possibility of gallstones problem.

How Much Caffeine is Safe?

For adults like us, less than 400mg should be fine. For children that are 12 years old and younger, maximum daily in take should be 2.5mg per kilogram. For pregnant women, please take no more than 200mg. Exceeding 500mg is bad for your health, may cause miscarriage, or low weight of the new baby.

Caffeine Excretion in your Body

Caffeine can be detected in your urine as early as half an hour after drinking. After 18 hours, the caffeine content will be completely excreted from your body. Usually, caffeine will start to kick in after 1-2 hours of drinking. Therefore, drinking tea with caffeine 1-2 hours before going bed is not a good idea unless you're working late or finishing a drama series on Netflix.

Here are some types of teas with high caffeine level. We hope this list will help you decide what type of tea you need for your next tea time.
