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: 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 - PROMOTES HEALTHY HAIR, SKIN & NAILS - Superior Source Biotin helps support Healthy Hair, Nails and Skin.

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 *by S***C on 19 September 2025* Along with the other well known benefits of L-theanine, this microlingual helps me sleep. 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. ### ⭐⭐⭐⭐⭐ Review *by A***R on 2 April 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? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/625695536-l-theanine-200-mg-brain-health-support-supplement-for-adults](https://www.desertcart.vn/products/625695536-l-theanine-200-mg-brain-health-support-supplement-for-adults) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-17*
