This is usually a rather hard to find and expensive supplement. This is the cheapest I've seen it. It is pure and it is the real deal and packaged in the U.S., so you know you're not getting fake stuff from China. L-Theanine is the stuff in tea that makes you feel calm and relaxed. I was once placed temporarily on Xanax for anxiety attacks that had no explanation. Then I looked up the side-effects of Xanax and found out how addictive that stuff was and how it has brought so many onto a downward spiral of misery. I started looking for more-friendly, all-natural alternatives, and that's when a web search revealed L-Theanine as an alternative to me. I didn't stop the Xanax cold turkey, but within two weeks, I was able to titrate and wean myself off of it entirely and replace it with L-Theanine. I then slowly reduced the amount of L-Theanine I was taking down to 100 mg. I now only take it because it makes me feel better during generally stressful situations, not because I need it. This a very powerful amino acid. It can also take the edge off of caffieine if you use that as a smart drug. L-Theanine + Caffeine = a feeling of clear focus without the crash or jitteryness. No daily recommended value has been established, but I would suggest taking 200 mg once to twice daily (400 mg max) and starting out from there. I've found that if I go over 400mg, I start to feel really drowsy and sluggish. Each person is different, so you may have to vary this amount for you. Also, if you want lucid dreams or have trouble sleeping, this is an excellent addition to melatonin. L-Theanine is for the most part non-toxic. There are no documented cases of anyone overdosing on it, but to be on the safe side, handle it like care like any other supplement. The package says on it, "Do not use if you are taking blood pressure medication." This does not necessarily mean that you can't use it. I am currently taking blood pressure medication for high blood pressure and I am doing just fine on L-Theanine. I have also never heard of anyone one high blood pressure medication having problems with L-Theanine. I believe this statement is just a warning so that the company can protect itself from liability in the rare event that someone does have a reaction. If you want to be 100% safe, talk to your doctor first. But, remember, this is pretty much a refined tea leaf-type extract without the caffeine stuff. If you drink lots of green tea, then you probably are already getting lots of L-Theanine in your diet. Review: As described, just a power. - I like this product to help me relax for sleep but it would be different reasons others may take it. ## Features - Item Category: Nutritional Supplement - Item Trademark: GENERIC - manufacturer: BulkSupplements ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00E7GESLA | | Age Range Description | Adult | | Best Sellers Rank | #78,765 in Health ( See Top 100 in Health ) #1,917 in Multivitamins Nutritional Supplements | | Brand | BulkSupplements | | Brand Name | BulkSupplements | | Color | green | | Container Type | Bag | | Customer Reviews | 4.5 out of 5 stars 1,615 Reviews | | Diet Type | Gluten Free | | Dosage Form | Powder | | Flavor | Unflavored | | Flavour | Unflavored | | Item Dimensions | 13 x 20.3 x 1.3 centimeters | | Item Form | Powder | | Item Weight | 100 Grams | | Item dimensions L x W x H | 13 x 20.3 x 1.3 centimeters | | Item form | Powder | | Item weight | 100 Grams | | Manufacturer | BulkSupplements | | Manufacturer Part Number | 4081062 | | Material Features | Antioxidant | | Material Type Free | Gluten_Free | | Model Name | BULKSUPPLEMENTS.COM L-Theanine Powde | | Number of Items | 1 | | Primary Supplement Type | L-Theanine | | Primary supplement type | L-Theanine | | Product Benefits | Antioxidant | | Special Ingredients | Amino Acid | | Specific Uses For Product | Laboratory | | Supplement Formulation | Individual Supplement | | Total Servings Per Container | 500 | | UPC | 849720005236 | ## Product Details - **Age range (description):** Adult - **Brand:** BulkSupplements - **Diet type:** Gluten Free - **Flavour:** Unflavored - **Item dimensions L x W x H:** 13 x 20.3 x 1.3 centimeters - **Item form:** Powder - **Item weight:** 0.02 Kilograms - **Primary supplement type:** L-Theanine - **Product benefits:** Antioxidant - **Special ingredients:** Amino Acid ## Images ![Pure L-Theanine Powder (100 grammes) - Image 1](https://m.media-amazon.com/images/I/61zl4p28-SL.jpg) ![Pure L-Theanine Powder (100 grammes) - Image 2](https://m.media-amazon.com/images/I/71mVKsrxxUL.jpg) ![Pure L-Theanine Powder (100 grammes) - Image 3](https://m.media-amazon.com/images/I/71eZntbGyqL.jpg) ![Pure L-Theanine Powder (100 grammes) - Image 4](https://m.media-amazon.com/images/I/71+LxzpjqUL.jpg) ![Pure L-Theanine Powder (100 grammes) - Image 5](https://m.media-amazon.com/images/I/71UcJzeABVL.jpg) ## Questions & Answers **Q: What is L-Theanine powder?** A: L-Theanine is a naturally occurring amino acid found in tea leaves, known for its calming effects without drowsiness. **Q: What are the benefits of the L-Theanine powder?** A: L-Theanine powder promotes relaxation, reduces stress, and enhances focus. **Q: How should I take L-Theanine powder?** A: Take 200 milligrams with 8-12 oz of water once daily.
