3 Side Effects Of Green Tea You Should Know

Green tea is a healthy powerhouse that has taken the world by storm. It was first used in China as a medicinal herb and now consumed by millions of people around the world.

‍Even though it is considered one of the safest and healthiest beverages to consume, there are still a few side effect most of which are experienced by individuals who are sensitive to caffeine or tannins.

Stomach-related Problems

Green tea may cause stomach irritation when brewed too strongly or consumed on an empty stomach. Also, it contains tannins that can increase the amount of acid in your stomach. Excess acid can lead to digestive issues including constipation, acid reflux, and nausea.

Also, the caffeine in green tea produces a laxative effect as it stimulates the colon muscles to contract and release more frequently. This results in more frequent trips to the bathroom and can cause an upset stomach.

Headaches

Green tea can cause headaches in certain individuals since it contains caffeine. People who suffer from migraines can consume green tea occasionally. However, you should avoid drinking green tea every day if you suffer from daily headaches. If you have a caffeine sensitivity, avoid drinking green tea.

Anaemia and Iron Deficiency

Green tea contains antioxidants that hinder the iron absorption in the human body. A meta-analysis showed that this side effect can be particularly dangerous for people who suffer from anaemia or other diseases where iron deficiency is present. To avoid this side effect, add lemon to your tea. The vitamin C in lemon promotes iron absorption, counteracting this side effect.
