Green Tea Extract Product Buyer’s Guide (updated July 2024)

Information About Green Tea Extract Products

Green Tea (Camellia sinensis) Extract is a concentration made of dried tea leaves that has attracted many consumers due to its antioxidant-rich nutrient profile. Antioxidants are often regarded as the main component necessary for a strong and functioning immune system. However, not all antioxidants are created equal. There are many types of antioxidants that fulfill different roles. Likewise, antioxidants can come from different sources and those sources are not equal. Green Tea Extract is one of the superior sources of antioxidants.

Green Tea Extract contains polyphenol antioxidants that contain an antioxidant class called catechins. One of those catechins is referred to as epigallocatechin gallate, EGCG for short. EGCG has been widely studied for its health benefits which include enhancing the body’s natural antioxidant processes, protecting against oxidative stress, increasing thermogenesis (burning calories), reducing the risk of cardiovascular diseases, and supporting neuroprotective processes. These are just some of the benefits that Green Tea Extract has to offer. 

Not all Green Tea Extract supplements work the same way because they are all made differently. There are many Green Tea supplements out there that don’t actually work. Nevertheless, given the right formula, from a quality manufacturer, you can experience the incredible benefits of a Green Tea Extract supplement. A higher percentage of EGCG will deliver more powerful results. In writing this, our goal is to give you the tools to determine whether or not a Green Tea extract is high quality and whether or not you should purchase it.

Key points to consider when choosing a Green Tea Extract supplement

When choosing a Green Tea Extract supplement, you should look for a company with a strong reputation that sells a wide range of natural nutritional supplements. An effective supplement will be formulated using high-quality Green Tea Extract that has been standardized to contain a high percentage of 90+% polyphenols, ~80% catechins, and 50% EGCG. Some Green Tea Extracts have caffeine while others have been decaffeinated so you should be sure to check the label to take that into account. Lastly, it’s important that any supplement you buy be made in an FDA registered laboratory that complies with the cGMP guidelines.  Having a safe facility is the first step to engineering a safe product and you don’t want to purchase from anyone who compromises on safety.

If you come across a company selling Green Tea Extract supplements using strong marketing terms or slogans, or if they are endorsed by famous celebrities, you should stay clear. If the company and product formula don’t speak for themselves, then nothing else should.

Now Foods Thermo Green Tea™

Promoted as a health product to scavenge free radicals and support thermogenesis, Now Foods Thermo Green Tea is our next product up for review. This product contains a 700 mg serving which is a higher dosage than the other Now Foods Green Tea Extract which contains only 400 mg but is otherwise not a very different product.

Rather than giving percentages and leaving you to do the math, Now Foods gives the significant numbers in mg. For example, Thermo Green Tea is not decaffeinated and contains up to 7 mg of caffeine. Additionally, it contains 350mg EGCG which would equal the desired 50%. However, there is no bioavailability enhancer in this formula to increase nutrient absorption and results.

Now Foods uses only pure ingredients that have been tested for purity. The manufacturing facility is FDA recognized and complies with the Good Manufacturing Practices (GMP). Continue reading our review for a more in-depth look at this product.

True Veda Organic Green Tea Extract

This product states that it is for helping support your immune system and promoting natural metabolism. It contains only 1 active ingredient, as can be expected. Any Green Tea Extract product should only contain Green Tea without any additives or preservatives. True Veda Organic Green Tea Extract is standardized to a 2:1 Herb to extract ratio. The complete concoction contains only 50% polyphenols. Additionally, it doesn’t seem to be decaffeinated as it contains “less than 10% caffeine” which could be quite a lot.

This product is manufactured in a GMP compliant facility and third-party tested. This product is on the cheaper side in terms of price but the lower dosage and standardization justify the price. Unfortunately, True Vida does not offer any satisfaction guarantee and refunds are only available for unused products that are still in the original packaging. This lack of a guarantee or helpful refund policy can be understood as a reflection on the company’s faith in their product. If they truly believed in its effectiveness, they would stand behind their product with a money-back guarantee.

Despite its testing and lack of unnecessary ingredients, there were a few matters that knocked this product down into third place. This product might not be as strong as you need it to be and we noticed a few inconsistencies. With only 50% polyphenols, how much EGCG is actually in each of these capsules?
