1. Side effects of teas

In our Comparison of the most famous types of tea you already get a good overview of the effects and special features of different types of tea. Here we would like to exclusively address the best-known and most common side effects of caffeinated teas.

1.1. Black tea side effects

Black tea For many people it is the more “aggressive tea” in contrast to green tea. You can find out how much caffeine is actually in black tea in our Comparison of effects and caffeine content.

Black tea works differently than unprocessed green tea due to the fermentation process of the green tea leaves. Oxidation destroys many antioxidants and other active ingredients. The caffeine content therefore increases in proportion. As with coffee, the caffeine is then largely unbound. This unbound caffeine leads to noticeable side effects, such as:

  • jitteriness
  • scattered thoughts
  • heart racing and
  • general malaise

The caffeine in black tea is largely bound to tannins, which are very healthy but bitter.

1.2. Green tea side effects

Green tea is considered the “milder tea”. It is said to be more pleasant than coffee and black tea and still have an invigorating effect. Green tea definitely has fewer side effects, but just like coffee and black tea, it is not the best when it comes to tolerance. Below we have summarized the most well-known side effects of green tea as bullet points.

  • Stomach tolerance: Green tea on an empty stomach is not a good idea if you are sensitive. You may experience discomfort and stomach pain.
  • Jitteriness: Despite being gentler than coffee, green tea quickly causes a kind of jitteriness that can be very unpleasant.
  • Erratic thoughts: Another side effect of green tea is erratic thoughts, which often arise from drinking green tea on an empty stomach or simply drinking too much.

In addition, with green tea, special attention must be paid to the brewing time, which is why we have a detailed guide for green tea fans Brewing time Have written.

1.3. Mate tea side effects

Mate tea, also called Yerba mate is also a well-known coffee alternative that is often sold as a “healthy energy drink alternative” for soft drinks. The fact is that these soft drinks are not significantly healthier, and even that pure Mate tea has some unpleasant side effects.

In our Comparison of natural energy drinksWe'll look at the best caffeinated energy sources.

Pure mate tea, on the other hand, like green tea and black tea, has some health benefits. We have told you what these are in our detailed article Mate tea effect provided. If you would like to find out more about the taste of mate tea, we also recommend the article “How does mate tea taste?“.

However, the side effects of mate tea are not without. Because the caffeine, like black tea, is predominantly bound to bitter substances, it has a rapid effect on the cardiovascular system and the head.

  • Nausea and other stomach problems
  • erratic thoughts without focus
