Green tea is traditionally enjoyed by straining the leaves in hot water. In recent times, companies have started to extract the active chemicals in this plant to produce supplements.

Green tea extracts have been scientifically proven to produce several health benefits in the human body. The main active chemical in the extract is known as EGCG, which is a potent antioxidant.

They have also been shown to act as an anti-anxiety compound. These extracts also boost the metabolic rate in the human body and may also cause energy expenditure to increase.

There are a lot of green tea extract supplements available today. Not all of these give you the dosage needed to benefit from the active chemicals truly. We share the best options you should consider in this post.

How We Ranked These Products

We did extensive research in order to filter through many supplements that contain green tea extracts. To bring you only the best options you can choose from, we looked at specific factors to filter out the products that will not provide you with value for your money. You will discover the specific elements that we looked at to find the top green tea extract supplements that you can buy right now.

Catechin Content

One of the first things to look at is the concentration of catechins that the green tea extract supplement contains. The concentration tells you how potent the formula is. A higher concentration means you are likely to experience more benefits provided by the green tea extract. A standard concentration for catechins is 40%. There are some of these supplements that will contain a higher or lower concentration, however.

Green Tea Extract Dosage

The dosage of green tea extract is another important factor to look at. Even when the concentration of catechins is high, a low dose will reduce the impact that the supplement will have on your health. Look for a product that can give you an adequate dose – most people find that about 400 mg and upward tend to offer them with appropriate results. A more potent dose of green tea extract may be needed if you do not experience significant benefits with such a product – but this does increase the amount of caffeine you obtain per serving.

Added Ingredients

Some of the green tea supplements on the market contain added ingredients. The idea behind these ingredients would usually be to give you a more potent effect and to offer more health-related benefits. Look closely at the added ingredients and evaluate whether these are truly necessary.

Wrapping Up

Green tea is known for its ability to boost metabolism, which could assist in weight loss. These supplements may also improve mental functioning and might also be useful as a way of reducing the risk of certain cancers. We analyzed quite a few green tea extracts on the market to bring you the top options worth considering if you want to experience the full benefits of the active chemicals.
