Definite noticable difference when I take it and don't. Couldn't recommend enough. I have around 2 with my dinner, and one before I sleep. Sometimes one during the day if I am feeling extra stressed! Review: Would recommend... - For long term cognitive and sleep benefits... I bought this for my younger brother, unable to mention how it is working as this is not something to use for the short term. High quality magnesium nonetheless ## Features - ✔️COGNITIVE SUPPORT INCLUDING LEARNING, MEMORY, MOOD, RELAXATION & SLEEP. Having sufficient levels of circulating magnesium in the brain is critical to cognitive health. Magtein Magnesium can effectively raise these levels resulting in improved recall, reduced age-related memory issues, and relaxation. - ✔️SUPERIOR BIOAVAILABILITY. Many forms of magnesium are poorly absorbed by the body. Magtein Magnesium is the only high absorption, clinically studied magnesium of its kind, shown to effectively raise concentrations in the brain. What isn’t used by the brain is distributed to various areas of the body, where it assists in regulating heart and lung function, muscular contractions, hydration, and more than 300 other vital processes. - ✔️MAXIMUM POTENCY 2100MG MAGTEIN MAGNESIUM PER 4 CAPSULE SERVING. Our Magtein Magnesium supplement has the highest level of active ingredient on the market containing 2100mg per 4 capsule daily serving. - ✔️RECOMMENDED BY EXPERTS. Leading neuroscientists including Dr. Andrew Huberman recommend consuming this specific form of Magnesium to help with initially falling asleep and for a deeper sleep. Magtein Magnesium is one component of the 'sleep cocktail' alongside Apigenin and L-Theanine, three supplements that work synergistically to improve sleep quality. - ✔️GENUINE MAGTEIN MAGNESIUM, 100% VEGAN WITH NO FILLERS, BINDERS OR ADDITIVES. At Time Health we believe in clean nutrition which is why you won’t find any nasty stuff in our products including any binders, fillers or additives. Buyers should be aware Magtein is a very expensive ingredient and should therefore exercise caution before purchasing much cheaper alternatives. Verification can be made through the official distributor list published by Magtein. - ✔️UK MADE TO HIGH QUALITY GMP STANDARDS, NEXT GENERATION NATURAL & ECO PULLULAN CAPSULES. Our Magtein Magnesium supplement is manufactured in the UK to GMP standards, ensuring the highest quality. Many cheaper supplements use capsules made from hypromellose which goes through heavy processing and produces non-environmentally friendly, harmful bi-products. Pullulan is the next generation in encapsulation, derived from tapioca and processed with water. - 🌳OVER 100,000 TREES PLANTED AND COUNTING. We are proud supporters of Ecologi’s reforestation projects and contribute a portion of each sale to tree planting efforts in the UK and abroad! We also contribute to rewilding efforts and carbon dioxide removal by funding the development of new blue carbon sinks. - Please note: packaging may vary. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B3F6YQPC | | Age Range Description | Adult | | Benefits | Brain Health Support, Sleep Support | | Best Sellers Rank | 1,826 in Health & Personal Care ( See Top 100 in Health & Personal Care ) 39 in Magnesium | | Brand | Time Health | | Brand Name | Time Health | | Country Of Origin | United Kingdom | | Customer Reviews | 4.5 out of 5 stars 1,082 Reviews | | Diet Type | Vegan | | Flavour | Unflavoured | | Item Form | Capsule | | Item Weight | 168 Milligrams | | Item form | Capsule | | Manufacturer | Time Health | | Manufacturer Part Number | 5060808511219 | | Model Number | 5060808511219 | | Number of Items | 1 | | Primary Supplement Type | Magnesium | | Primary supplement type | Magnesium | | Product benefits | Brain Health Support, Sleep Support | | Unit Count | 120 count | | Unit count | 120 count | ## Product Details - **Age range (description):** Adult - **Brand:** Time Health - **Diet type:** Vegan - **Flavour:** Unflavoured - **Item form:** Capsule - **Item weight:** 168 Milligrams - **Number of items:** 1 - **Primary supplement type:** Magnesium - **Product benefits:** Brain Health Support, Sleep Support - **Unit count:** 120 count ## Images ![Magnesium L-Threonate - Highly Bioavailable - Cognitive & Sleep Support - Image 1](https://m.media-amazon.com/images/I/61JRJzO377L.jpg) ![Magnesium L-Threonate - Highly Bioavailable - Cognitive & Sleep Support - Image 2](https://m.media-amazon.com/images/I/71Iy6SxrWhL.jpg) ![Magnesium L-Threonate - Highly Bioavailable - Cognitive & Sleep Support - Image 3](https://m.media-amazon.com/images/I/71yrkEPzDCL.jpg) ![Magnesium L-Threonate - Highly Bioavailable - Cognitive & Sleep Support - Image 4](https://m.media-amazon.com/images/I/71Oa+vWy3vL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Hi there, how much elemental magnesium is in each capsule (not serving but per capsule ???** A: 50g of mag l threonate per capsule 38g of magnesium per capsule.

These are really great for relaxing the mind at bedtime & deep sleeps.. *by E***T on 10 June 2026* Took just 3 to 4 nights of consistently taking, (one capsule before bedtime) for these to begin to kick in & do it's thing.. Wow! Haven't slept as well as this since I was a baby.. Now middle aged & just really appreciating a quality deep sleep each night! Wake up feeling I've had a deep restorative sleep as opposed to a wrestless bad night's sleep. Whatever these Magtein Magnesium Threonate capsules are doing to my brain each night is wonderful for a great night's sleep.. they really help you switch off in mind at bedtime & relax your brain/mind into a deep sleep. Don't wake up even once during the night, just blissfully sleep all the way through till morning.. You won't know until you try out these particular capsules! Yes they're rather pricey, however think of it as it's almost 120 night's of excellent quality deep sleeps...zzz Worth the money for me personally. Would highly recommend. ## Frequently Bought Together - Magtein® Magnesium – 120 Capsules – High Strength 2100mg – Pullulan Capsules – UK Made to GMP & HACCP Standards – Zero Additives - New: L-Theanine - Natural Green Tea Extract (Decaf) - 120 Capsules - 300mg L-Theanine per Serving - Sleep & Relaxation Support - Mental Clarity - Non-Synthetic Theanine - UK Made - Zero Additives - Apigenin - 50mg x 120 Capsules - 98%+ Purity - Optimal Dose for Sleep & Relaxation Support - NAD+ Booster - Grapefruit Source - UK Made - GMP Standards - Zero Additives (120 Count (Pack of 1)) --- ## 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.jp/products/443944616-magnesium-l-threonate-highly-bioavailable-cognitive-and-sleep-support](https://www.desertcart.jp/products/443944616-magnesium-l-threonate-highly-bioavailable-cognitive-and-sleep-support) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-08*
