Green Tea Extract Supplements Guide

Green tea is composed of the leaves of the Camellia sinensis which is primarily grown in Asia. However, don’t mistake black tea as the same as green tea since it tends to be over processed. Green tea, on the other hand, is processed very little which helps preserve nutrients in the leaves.

Green tea has been used for centuries in China and Asia due to its list of health benefits. Soon after, it grew to other parts of the world and dominated the market of all-natural medicines.

What is Green Tea Extract?

Green tea extract is a type of prepared supplement made entirely from green tea leaves. Primarily speaking, there is no major difference between eating or drinking green tea since they offer the same health benefits and results.

The main reason behind the overhaul of health benefits that come with green tea extract is from a chemical called polyphenols. This type of chemical is used to help protect the plant from microorganisms that cause disease and decay, as well as protection from various types of radiation.

Although there are many types of polyphenols that are contained in the green tea plant, the most important one is called catechin. This type of polyphenol contains the highest health advantages when consumed. In addition to the polyphenol, the majority of green tea supplements also include small doses of caffeine since they too have benefits. However, if you’re against the use of caffeine, there are also decaffeinated types of supplements but less research has been conducted on them.


There are certain side effects associated with taking green tea extract supplements. Some people experience headaches, dizziness, upset stomach, nausea, and diarrhea. If you experience any of these effects or they worsen, you should refrain from taking the supplement and see your doctor.

There are a few more, less common side effects that some people may experience. This includes restlessness, trouble sleeping, tremors, increased or irregular heartbeat, mood changes, and seizures.

Some people also experience allergic reactions to green tea extract, although this is very rare. If you notice any of the symptoms of an allergic reaction, such as rash, dizziness, swelling, and difficulty breathing, you should get medical help immediately.

You may also give a second thought to using green tea extract supplements if you experience certain disorders.

If you have any allergies, you should talk to your doctor before taking this extract. Even if you are not allergic to green tea, it contains inactive ingredients that can cause an allergic reaction.

You should also not take green tea extract supplements if you have any of the following health issues:

  • Bleeding problems
  • Heart problems
  • Anemia
  • Liver problems
  • Intestinal or stomach problems
  • Glaucoma
  • Bone problems
  • Mental or mood disorders
  • Low calcium levels

If you experience any of these issues, you should speak with your doctor before doing so.

When taking the liquid version of this supplement, speak with your doctor and proceed with caution. This form can contain sugar or alcohol, which can be harmful for people with liver disease, alcohol addiction, or diabetes.

If you are pregnant or breastfeeding, you should also talk to your doctor before beginning to take this supplement. Green tea contains caffeine, which pregnant women should not consume a lot of.

Always speak with a medical professional or doctor before taking any supplements. Always read the product label for instructions and directions.

Taking Green Tea Extract Supplements

Green tea extract supplements can be taken in a number of forms. This includes liquid, powder, and capsules.

The recommended dosage of green tea powder is between 250 and 500 mg daily. Your ideal dosage may depend on your age, weight, height, and the reason why you are taking the supplement.

It will also be dependent on the strength of the supplement and its overall quality. This recommended dosage is based on a high quality green tea extract supplement with a 95% or more purity.

To get a more personalized dose, speak with your doctor or refer to the instructions on the back of the supplement.

Things to Look for in a Good Green Tea Extract

There are a few things you should consider before purchasing your green tea extract supplement.

1. Form

Green tea extracts are available most commonly in powder, liquid, and capsule form. If you have difficulty swallowing pills, you should consider purchasing the liquid form.

2. Levels of Caffeine

Almost all green tea extract supplements will contain some amount of caffeine, though some have more than others. Even decaffeinated supplements contain trace amounts of caffeine of between 0 and five mg per capsule. If you are trying to limit your caffeine intake, try to find a supplement with the lowest levels possible.

3. The Percent of Catechins

Catechins are the antioxidant in green tea that provides the most benefits. Look for a supplement that has the highest percentage of catechins. This will give you the most healing power and the best value for your money.

4. EGCG Levels

EGCG is a type of catechin that is extremely beneficial. Look for a green tea extract supplement that contains a high percentage of EGCG.

5. Dosage Size

Check on the label to determine the suggested dosage. Some capsules are stronger than others. So, a weaker supplement may be able to offer the same amount of green tea extract in three pills as a stronger supplement can provide in one pill. Try to find one that meets all of your needs.
