Tea Caffeine Guide

How much Caffeine is in your tea?

The amount of Caffeine varies depending on the type of tea. Herbal Tea has no caffeine. Nor does Rooibos. Black tea has the most. Take a look at the chart below to get a rough idea of how much pep is in your cup.

The strength of your brew can also impact the actual amount. The chart above is based on an 8 oz cup of tea brewed according to the brewing instructions that come with each bag of Serene Tea.

Some Interesting Caffeine Nibs:

  • One theory claims that people with blood type A are more sensitive to caffeine than those with the other three blood types.
  • Some studies have shown that caffeine speeds up your metabolism and helps you burn fat 30% faster. Too much, however, can overstimulate cortisol production and actually causes carb cravings and triggers fat storage in the abdomen. (So if you are drinking 3-4 cups of coffee a day, consider switching out a couple of those for green or herbal tea.)
  • Caffeine can stay in your system for up to 8hrs.  Experts recommend you switch over to white or herbal tea after 2pm in the afternoon so you don't disrupt your sleep.
