🧠 What Is Magnesium L-Threonate?
Magnesium L-Threonate is a magnesium compound formed by binding elemental magnesium to L-threonic acid — a metabolite of vitamin C. The compound was developed and patented by researchers associated with MIT in 2010, originally branded as Magtein®. Generic magnesium L-threonate is the non-branded version of the same compound supplied without the patented Magtein® marketing license.
L-threonate is one of several available magnesium chelate forms, alongside:
- Magnesium Glycinate — chelated with glycine. Common for general use.
- Magnesium Citrate — bound to citric acid. Common for digestive comfort.
- Magnesium Oxide — basic inorganic form. Low absorption.
- Magnesium Malate — chelated with malic acid. Used in energy formulations.
- Magnesium Taurate — chelated with taurine.
- Magnesium L-Threonate — the form supplied in this product.
Each capsule of this product contains 650mg of magnesium L-threonate, providing approximately 58.5mg of elemental magnesium (based on a 9% elemental content typical for the L-threonate form). The remaining mass is the L-threonic acid component of the chelate.
🛍️ First-Time Buyer Guide
If you're new to magnesium L-threonate, here's what to know:
- L-threonate ≠ glycinate. If you've taken magnesium glycinate, citrate or oxide before, L-threonate is a different form entirely.
- Elemental content is lower. 650mg of magnesium L-threonate provides ~58.5mg elemental — lower than glycinate per gram.
- Many users take 2–3 capsules daily. Most published research uses doses in the 1–2g range of L-threonate per day.
- UK safe upper level applies. Don't exceed 400mg supplemental elemental magnesium per day in total.
- This is generic L-threonate — not the patented Magtein® form. Buyers seeking specifically Magtein® branded products should source separately.
Elemental magnesium is associated with the following UK authorised health claims under the GB NHC Register (only when consumed in sufficient quantity):
- Contributes to normal functioning of the nervous system
- Contributes to normal psychological function
- Contributes to normal muscle function
- Contributes to normal energy-yielding metabolism
- Contributes to electrolyte balance
- Contributes to normal protein synthesis
- Contributes to the maintenance of normal bones and teeth
- Contributes to the process of cell division
- Helps to reduce tiredness and fatigue
Each capsule of this product provides ~58.5mg elemental magnesium (~15% NRV). Authorised claims apply when daily intake reaches significance against the NRV (240mg). No authorised claims exist specifically for the L-threonate form or for memory or cognition.
🔬 Understanding Magnesium L-Threonate
Magnesium L-threonate is formed by binding elemental magnesium to L-threonic acid, a metabolite derived from vitamin C. The result is a magnesium chelate with distinct physicochemical properties from other magnesium forms.
Magnesium L-threonate is the magnesium form most commonly associated with academic research into magnesium and memory, cognition, and the nervous system. References to peer-reviewed studies are listed in the PubMed section further down this page.
650mg of magnesium L-threonate provides approximately 58.5mg of elemental magnesium (~9% by weight). The remaining mass is the L-threonic acid component of the chelate structure.
This product supplies generic, non-branded magnesium L-threonate — the unbranded compound. Magtein® is a registered trademark for a specific patented form of magnesium L-threonate manufactured under licence. Buyers seeking Magtein® specifically should source it separately.
Single-ingredient capsule containing only magnesium L-threonate inside a vegan HPMC capsule shell. No fillers, no flow agents, no magnesium stearate, no excipients, no bulking agents.
