Let two dissolve UNDER THE TONGUE every night and get the sleep you have been missing! Who knew that a simple amino acid could be so powerful to allow you to sleep, and calm the brain so you can get BACK to sleep after getting up to use the bathroom! I used to take drugs to sleep 7-8 hours. No longer need them! I have these on auto-ship! Review: A Favorite Sleep Aid - Along with the other well known benefits of L-theanine, this microlingual helps me sleep. The one objection I have to purchasing it on desertcart is the large FNSKU sticker placed on the box. This happens with other supplements I have bought on desertcart as well. And they are stuck fast so that removing them, removes the information under it. ## Features - L-Theanine Supplement Aids Relaxation: L-Theanine 200 mg is a health supplement for adults, crafted to support natural relaxation and concentration - Supplement Formula Aids Better Sleep: Our L-theanine supplement supports sleep quality naturally and aids relaxation for a restful night - Brain Health Support: L-Theanine 200 mg aids brain health by supporting concentration and the regulation of neurotransmitters - Health Supplement for Energy: Each serving of this L-theanine supports energy as well as appetite and alertness, supporting overall health and vitality - About Us: Superior Source has been formulating sublingual vitamins since 1998 in our family-owned manufacturing facility ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071CLQMMD | | Age Range Description | Adult | | Allergen Information | Non-GMO | | Best Sellers Rank | #82,148 in Health & Household ( See Top 100 in Health & Household ) #93 in OTC Medicinal Sleep Aids | | Brand | Superior Source | | Brand Name | Superior Source | | Color | White | | Container Type | Bottle | | Customer Reviews | 4.5 out of 5 stars 118 Reviews | | Dosage Form | Tablets | | Flavor | Unflavored | | Item Dimensions | 1.5 x 1.5 x 3.5 inches | | Item Form | Tablet | | Item Weight | 0.08 Pounds | | Manufacturer | Continental Vitamin Company, Inc | | Manufacturer Part Number | 90045 | | Material Features | GMO Free | | Material Type Free | Magnesium Stearate Free, No Artificial Colors, No Artificial Flavors | | Model Name | L-Theanine 200 mg, Under The Tongue Quick Dissolve Sublingual Tablets, 100 Ct, Promotes Relaxation & Facilities Restful Sleep, Non-GMO | | Number of Items | 1 | | Primary Supplement Type | Lactose, L-Theanine, Stevia and Gum Arabic | | Product Benefits | Sleep Support | | Specific Uses For Product | Supports Healthy Energy & Growth | | Total Servings Per Container | 100 | | UPC | 076635900459 | | Unit Count | 100 Count | ## Product Details - **Age Range (Description):** Adult - **Brand:** Superior Source - **Flavor:** Unflavored - **Item Form:** Tablet - **Item Weight:** 1.28 ounces - **Item dimensions L x W x H:** 1.5 x 1.5 x 3.5 inches - **Package Information:** Bottle - **Primary Supplement Type:** Lactose, L-Theanine, Stevia and Gum Arabic - **Product Benefits:** Sleep Support - **Unit Count:** 100 Count ## Images ![Superior Source L-Theanine 200 mg - Brain Health Support Supplement for Adults - Supplement Formula Aids Better Sleep & Daily Energy - Supports Concentration Naturally - 100 Instant Dissolve Tablets - Image 1](https://m.media-amazon.com/images/I/817ktYd3OmL.jpg) ## Questions & Answers **Q: Are these manufactured in USA?** A: Yes, SuperiorSource is a Manufacturing company based in California. **Q: Will this work for everyone ?** A: I using every night to sleep, it helps but I won't buy again. **Q: what are the ingredients?** A: L-Theanine 200mg.

The one objection I have to purchasing it on Amazon is the large FNSKU sticker placed on the box. This happens with other supplements I have bought on Amazon as well. And they are stuck fast so that removing them, removes the information under it. ### ⭐⭐⭐⭐⭐ Ride the tiger. You can see his stripes so you know he's clean. Oh don't you see what I mean?! *by A***E on April 2, 2025* Does it do what it says? I dunno. Does it taste good? Yes. Does it dissolve easily? Again I dunno, because if it doesn't melt away in two seconds I start chewing `em. I don't eat Jolly Ranchers or jawbreakers for the that same reason. These might melt in three seconds and absorb a half second later, but who has that kind of time, amIrite?!?!?!? I am fond of this brand in general and use their Iron and b vitamin supplements as well. ## Frequently Bought Together - Superior Source L-Theanine 200 mg - Brain Health Support Supplement for Adults - Supplement Formula Aids Better Sleep & Daily Energy - Supports Concentration Naturally - 100 Instant Dissolve Tablets - Superior Source GABA 100 mg, Quick Dissolve MicroLingual Tablets, 100 Count, Brain Health Support, Promotes a Relaxing Effect & Positive Mood, Stress & Sleep Support, Non-GMO - Superior Source 5-HTP 50 mg - Natural Supplement Aids Restful Sleep & Neurotransmitter Functions - Brain Health & Function Support - 5-Hydroxytryptophan Supplement - 60 Instant Dissolve Tablets --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/74303787-superior-source-l-theanine-200-mg-brain-health-support-supplement](https://www.desertcart.tn/products/74303787-superior-source-l-theanine-200-mg-brain-health-support-supplement) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-24*
