Works through the night when you body need it and Sports Research has the highest quality supplements available. Review: [Supplement Sleuth] An authentic, clean-label approach to brain-permeable magnesium - While I review a significant number of supplements through the Vine program, this product is a long-standing fixture in my personal stack. Sports Research’s Magtein Magnesium L-Threonate strikes a great balance between ingredient quality, clean formulation, and overall value. ​1. The Blood-Brain Barrier Advantage What makes this product stand out is its use of Magtein, the patented form of magnesium L-threonate. Researchers have observed that this specific compound crosses the blood–brain barrier more readily than standard magnesium salts like citrate or oxide. For a "Sleuth," this is the primary reason to pay the premium for Magtein—it is specifically designed for cognitive and synaptic support. ​2. Authentic Patented Blend Sports Research uses the authentic, standardized Magtein blend. This ensures that the magnesium L-threonate is supported by the correct magnesium salts to achieve precise elemental dosing. This isn’t "filler"—it’s a necessary part of how the patented ingredient is manufactured to ensure consistent potency. ​3. Clean Excipient Profile One of my favorite features here is the clean excipient profile (the list of inactive ingredients used to make the capsule). These capsules use vegetable cellulose and avoid unnecessary additives like artificial binders or stearates. For a daily supplement, having a minimal, low-risk inactive list is a meaningful advantage for long-term health. ​4. Manufacturing and Value Sports Research routinely performs third-party testing for identity, purity, and potency. While Magtein is a more expensive form of magnesium, this version remains reasonably priced without compromising on the genuine complex. The capsules are easy to swallow, have no aftertaste, and represent a well-executed example of a high-tier magnesium supplement. ​Verdict: 5 Stars. It delivers authentic Magtein, clean ingredients, and dependable quality at a fair price. It's an excellent choice for anyone specifically looking for the cognitive benefits of magnesium L-threonate. ## Features - HIGHLY BIOAVAILABLE FORM: Magnesium L-threonate is the salt formed from mixing magnesium and threonic acid, a water-soluble substance derived from the metabolic breakdown of vitamin C. Easily absorbed, our magnesium L threonate capsules are used for their overall brain health benefits and may help support memory, focus, relaxation, mood, and cognition. - MADE WITH MAGTEIN: Magtein is a patented compound called threonic acid developed by a group of MIT researchers.

I’ve been taking another brand of magnesium L-Theronate for about a year with some benefit but not very noticeable. I recently switched to this brand, the difference has been very noticeable…like WOW! I take 3 with dinner and now I’m sleeping deeply through the night, waking up feeling refreshed. My mind feels sharper too, more alert during the day. So glad I found this brand, it’s a winner. ## Frequently Bought Together - Sports Research Magtein Magnesium L-Threonate Capsules - Magnesium Supplement for Memory, Focus & Cognition - Magnesium L Threonate Supports Brain Health, Sleep & Mood- 2000mg, 180 Capsules for Adults - Sports Research® Vitamin D3 + K2 with Coconut MCT Oil | Vegan D3 5000 IU with K2 100 mcg for Bone & Immune Health | Vegan Certified, Soy & Gluten Free - 120 Softgels - Sports Research Turmeric Curcumin C3 Complex - Softgels with Bioperine Black Pepper Extract & Organic Coconut Oil, Standardized 95% Curcuminoids - Non-GMO Verified & Gluten Free - 500mg, 120 Count --- ## 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/554072711-magnesium-l-threonate-capsules-2000mg-high-absorption-magtein-for-enhanced](https://www.desertcart.tn/products/554072711-magnesium-l-threonate-capsules-2000mg-high-absorption-magtein-for-enhanced) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-05*
