Best Green Tea Supplements of 2025

"Taking these supplements is much easier than drinking tea. I can use them anywhere, anytime, with no mess. They really help with my appetite suppression and I love the benefits of green tea."

"These Green Tea Pills are a convenient way to add an antioxidant powerhouse to my daily routine. I've felt a subtle energy boost and appreciate the health support they provide. The capsules are easy to swallow and the bottle is compact for travel."

"I’m so glad I discovered these. After giving up coffee for medical tests, they were a godsend. They provided just enough caffeine to help me focus without side effects, and I could sleep soundly at night."

"In my opinion, this is a great product. Honestly, people should read the description before buying, as it contains a lot of helpful information. You can't blame the product if you didn't read the details. Overall, I think it's fantastic!"

"I bought this without checking the mg strength. The one I used for years was 1000 mg. After taking this, I felt very nauseous and experienced symptoms similar to a panic attack. It was awful, but I don't want to underrate the product because it was my oversight. If you're looking to boost your energy and suppress appetite, this might be the right dosage for you!"

"These are the second brand of green tea extract pills I've tried. The first one didn't work, but with this brand, I'm seeing results! I've been trying to lose those stubborn 5 to 8 pounds despite my plant-based diet and exercise routine, and I think I've finally lost weight thanks to these green tea pills. I would definitely recommend them!"

"I was a bit skeptical about this product, but after reading various reviews, I decided to give it a try. It's incredibly affordable and actually works! After about a month and a half of using it, I've lost about 8 pounds and 1.5 inches off my waist. I take one in the morning and another after lunch, and it gives me plenty of energy throughout the day. Just a heads up, avoid excessive caffeine while using it!"

"Now's Green Tea Extract is priced fairly and provides 400mg per tablet, so I only need one a day. I noticed a slight boost in energy and some help with anxiety due to the L-theanine it contains. After struggling for years with anxiety medications, I managed to reduce my dosage significantly thanks to this and other supplements. It’s been life-changing for me!"

"I've always trusted Now Foods products based on my past purchases, so I felt safe trying this Green Tea Extract. I have IBS and was concerned about caffeine effects, but I didn't have any digestive issues. Instead, I've experienced a nice energy boost that helps me keep up with my exercise routine after work. This product has definitely contributed to speeding up my metabolism."

"About 15 years ago, I lost 40lbs in 4 months with green tea extract as part of my regimen. It was one of the few supplements I could truly feel working, alongside caffeine. I definitely experience a boost in energy from it. After regaining weight over the years, I’m gearing up to exercise again and green tea extract is a top choice for my supplements. I appreciate that it includes vitamin C too!"

"I usually take one capsule at noon for an energy boost, which feels like having two cups of green tea. It keeps me energized until bedtime, but I avoid taking it late to prevent sleep disruption. This supplement is perfect for road trips or long drives, as it not only gives me energy but also supports my immune system. Occasionally, I might take more on weekends for projects requiring extra energy and focus. The capsule is not bitter or sour, but I still drink water with it for effectiveness."

"I ordered these green tea extract capsules to see if they could help suppress my appetite, similar to liquid apple cider vinegar. I don’t have time to make fresh green tea, but I know it offers great health benefits. Though it's still early to tell, I'm hopeful about seeing improvements in my appetite and overall health from these pills."

“I find these capsules great for an afternoon energy boost.”

“I would definitely recommend these; they've noticeably improved my immune health and cognitive functions. The added benefit of supporting heart health is a wonderful bonus. Knowing they have undergone quality control audits makes me feel confident about using them. Getting 1000 mg of green tea extract in a convenient capsule is fantastic for my daily routine.”

“I noticed a slight energy increase when I incorporate these into my daily vitamins, which makes me feel more motivated to get things done.”

"Not everyone enjoys the taste of green tea, but I find the benefits undeniable. I've been using green tea extract on and off for years, and when I take it, I definitely feel more energetic and notice an acceleration in my metabolism. It's a fantastic addition to my vitamin regimen!"

"I've been taking this supplement for years, and when I ran out last month, I really felt the change in my daily routine. I noticed my energy dropped and my junk food cravings returned. Once I reordered, my energy came back instantly, and I felt much better. It's a great quality supplement!"

"As an older guy, I find this product beneficial, but I do wake up a few times a night to use the bathroom."

"I have been using this product for about a year, after my functional medicine practitioner recommended it. It has strengthened my immune system."

"I appreciate this product because it provides the extract I need from green tea without the caffeine. It's easy to swallow!"

"This supplement was suggested by my dog's oncologist for his chronic lymphocytic leukemia. His cell count has remained steady or decreased since he started taking it, and he's doing great!"

"As a blood cancer patient, I recently began seeing a new oncologist who inquired if I was taking a green tea supplement, which I was. I used to take 3 or 4 capsules of 400 mg from another brand, so I find it much simpler to take just one 1800 mg capsule. I'm pleased with the product."

"I really appreciate these green tea tablets. They provide a good and safe amount of EGCG for various health benefits. I started with one capsule daily for a week before increasing to two. It's comforting to know that the 1,200 mg (2 capsules) with 45% EGCG gives me 540 mg of EGCG, which is a safe level to consume. Plus, I enjoy not having to drink so much tea!"

"I’ve noticed that I get energy from just one tablet a day, but I urge caution. If you have high blood pressure, a larger dose might elevate it. I had bought the larger 1800 mg tablets, and my blood pressure skyrocketed to 190/110. It's crucial to monitor your blood pressure while taking this supplement!"

“I’ve been struggling with belly fat since my mid-40s, but after taking the green tea extract, my weight dropped from 150.6 to 144.4 in just a week. It’s impressive, especially since it’s the only change I made recently.”

“I experienced nausea and sweating after taking this product on an empty stomach. It was uncomfortable, and I couldn’t go to work because of it. Just be cautious when trying it.”

“I love how I feel a boost from this product, even though I’m usually sensitive to caffeine. It’s a great addition to my routine!”

"I recently began taking Zenwise Green Tea Extract with EGCG & Vitamin C, and I’m incredibly impressed with its positive impact on my energy levels and overall well-being. This exceptional supplement deserves a 5-star rating for its effectiveness and quality. Its energizing properties provide a gentle boost without the jitters or crash, which has significantly improved my productivity and mood. The combination of green tea extract, EGCG, and Vitamin C creates a synergistic blend that promotes overall wellness."

"I've been taking this for a week and a half, primarily for the health benefits of EGCG and Vitamin C since I can't drink 7 cups of green tea daily. While I don't recommend it for drastic weight loss, I noticed by the second week that my appetite decreased. I take one capsule in the morning on an empty stomach for better absorption, which works well for me. Overall, I think this supplement is good for health benefits, even if you’re not trying to lose weight."

"I finished a bottle of these supplements, and while my appetite decreased at first, it didn't last. Unfortunately, I didn't experience any weight loss."
