Suntheanine is a patented form of L-Theanine that derives from green tea and is used to promote focus, mental clarity, and relaxation without causing side effects like drowsiness. At least, these are the promises made by the manufacturer. The upper mentioned component is the major ingredient in Dr. Murray's Stress Relax Suntheanine L-Theanine, chewable tablets that received the "Food Ingredient Research Award" at the 1998 Food Ingredients Europe and were called the "Best New Product of 2000" at Nutracon. It should be noted that Suntheanine is produced via a proprietary enzymatic process providing pure L-Theanine for better results. It is said to be protected by more than forty U.S. and international patents.

Before moving further let's take a look at what is known about the manufacturer of the product. This supplement is made by Natural Factors, an American company that can be contacted at 14224 167th Ave. SE; Monroe, WA 98272. The company also offers a number of other dietary supplements. Suntheanine is available through some online stores, as well as at health food and vitamin shops. However, the official website says too little about the ingredients used in the supplement. It is only mentioned that the product contains a pure form of L-Theanine. According to the clinical research conducted by the company, 50 mg to 200 mg of Suntheanine can help to produce alpha waves in the user's brain, which can relax and alert your mind. This ingredient is promised to promote memory and learning, prevent jitters caused by caffeine, and reduce nervousness.

Ingredients of Suntheanine - Does It Really Work? Is It a Scam?

Based on our research, Suntheanine contains 200 mg of Suntheanine L-Theanine. It is the only active ingredient in this stress reliever. As it was already mentioned, this is a patented and pure form of L-Theanine. It derives from green tea, thus it is a natural compound. It has got accolades from Nutracon and the 1998 Food Ingredients Europe. The manufacturer claims on the official website that Suntheanine is clinically proven to promote relaxation and mental clarity. Suntheanine l-theanine contains 100% suntheanine, which an award-winning brand of theanine. Even though it has been a part of many human clinical trials and safety studies, this ingredient may be the reason of side effects and adverse reactions. As far as it is known, l-theanine is synthesized in the tea roots and transported to the leaves of plants, comprising about 2% of the total dry weight of the leaves. This ingredient is responsible for both the relaxing effects and the taste of green tea. L-theanine is known to be able to cross the blood-brain barrier within thirty minutes of intake and exert its effects on the brain.

Other ingredients of Suntheanine include xylitol, organic cane sugar, stearic acid, natural fruit flavor (banana, pineapple, pomegranate, passion fruit, and mango), silica, magnesium stearate (vegetable grade), and citric acid. The supplement comes in the form of tropical fruit flavoured chewable capsules. It is recommended to take 1-2 tablets, three times a day or as your doctor has prescribed to you. There is no information about possible side effects of the supplement on the official website, but this does not necessarily mean that the product is safe for human health. Besides, there is lack of clinical research showing that it can support the immune system, improve sleep, and relieve stress and symptoms linked to premenstrual syndrome. Let us take a look at potential side effects of the product and at what real users are saying about their experience of using this supplement.

Customer Reviews - Does It Have Any Side Effects?

This product is on the FDA regarded as safe list (GRAS), and it is well-tolerated in relatively healthy users above 18 years of age. However, Suntheanine is still associated with a number of side effects, based on reputable websites. The most common ones include headaches, irritability, insomnia, heartburn, and diarrhea. Do not overdose the supplement to decrease the risk of side effects. There is also a concern that this nootropic should not be used in combination with cholesterol lowering medications, sedatives, drugs used to treat anxiety and depression, as well as blood pressure lowering medications. If you are on any of these drugs, talk to a doctor before starting to take Suntheanine or any other nootropic product.

There are many customer reviews about the product on third-party websites but not all of them are as possible as desired. Many customers report seeing no difference when taking the supplement. One woman writes that she too it for her ADHD and did not notice any changes in her mood, memory, behavior, or brain functioning. It is more beneficial to have a daily exercise regimen and mindfulness meditation to reduce stress. Another complaint related the side effects that may be really awful. Some users share their experience of sleeping badly at night and feeling more anxiety during the day. One reviewer said that he tested the product and found out that there was no l-theanine in it, but just rice powder. Let us take a look at some of the actual customer reviews.

"I tried Suntheanine and just like many other supplements of the kind, this did nothing for my anxiety and mood. And I was taking the recommended dosage every day for many months. I am not someone who simply gives one star to any supplement that doesn't work. I have used the product for a long period of time. In addition, it gave me a weird, feeling that I didn't like."

"I was hoping that suntheanine would calm my nerves, but unfortunately it didn't. On the contrary, this product caused headaches and made me feel incredibly drowsy. I like to be relaxed but theanine leaves me in a state when I constantly want to sleep. At present, I just take it right before going to bed."

"Suntheanine is junk that almost wrecked my life. I just wanted to relieve my anxiety but instead it made me wake up at night with panic attacks. I became more nervous and anxious than before. It killed my appetite too. I have lost some body weight. My wife had the same issues with this product."

Where To Buy Suntheanine?

The supplement is not available on the official website of the manufacturer. You can buy it on some retail stores online. Amazon offers one bottle of 90 Veggie Caps from $13.37. There is no money-back guarantee on this product.

My Final Summary

Suntheanine has a number of weaknesses the major one of which is low effectiveness of this stress reliever. It's no surprise because the supplement as no solid clinical evidence of its safety and effectiveness. The manufacturer does not offer free samples, so you will not be able to try the product before buying a full bottle. A money back guarantee is not offered either. Another concern of ours is the chance of experiencing side effects when using this supplement. The product cannot be purchased on the Natural Factors website. It is available on such retail stores as Amazon. These capsules are also available in health food and vitamin shops. The manufacturer does not provide any results of clinical trials on their website. There is high chance that Suntheanine will not work for you well, so there is no sense to buy this product. The modern market offers a wide array of remedies for the treatment of depression and anxiety. With all this in mind, Suntheanine cannot be recommended to usage.

Affordable Alternative

Many modern health specialists are sure that the problem can be perfectly solved by another product known as ProVanax and I completely agree with them because study many products of the kind. I recommend you reading my ProVanax review. You'll be pleasantly surprised.
