## Description

Product description Sports Research Mag LT with Magtein Magnesium L-Threonate is the only form of Magnesium that effectively crosses the blood-brain barrier, increasing magnesium levels in the brain critical for improving cognitive function.* Made with Magtein Our formula contains Magtein, a patented form of magnesium developed by MIT researchers and clinically proven to cross the blood-brain barrier.* A Superior Experience 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.*

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.
