Magnesium L-Threonate

2g

Structure / Function

This is magnesium in a special form called L-threonateThe special carrier form of magnesium in this product — it's the one shown to raise magnesium inside the brain.. Regular magnesium does a lot of good work in your body. But most forms don't reach your brain very well. This one is the form shown to reach the brain. So it supports the everyday things magnesium does — calm, clear thinking, and restful sleep — while topping up your body's overall magnesium.

Magnesium is a mineralA basic nutrient your body can't make on its own and has to get from food or a supplement. your body uses as a helper for hundreds of jobs. It helps make energy from food. It helps your nerves send their signals. And it helps your muscles work. In the brain, magnesium helps brain cells talk to each other and stay calm and balanced. The L-threonate form is the one shown to raise magnesium inside the brain. That's why it's chosen here for clear thinking and a settled, calm feeling.

Evidence · 3 studies
  • One study followed 100 healthy adults for 6 weeks. They took 2 grams a day of this exact magnesium form. It supported better memory, focus, and reaction time. Lopresti & Smith 2026, Frontiers in Nutrition (PMID 41601871); corroborated by Zhang & Wang 2022, Nutrients (PMID 36558392), an RCT in 109 healthy adults.PubMed →
  • This magnesium form was also tested for sleep. At a lower 1-gram dose, people kept steady sleep quality. They also got more deep and REM sleep. At the 2-gram daily dose in this product, people had better daytime focus and alertness. Hausenblas & Gu 2024, Sleep Medicine: X (PMID 39252819), a 1 g/day trial; sleep-related impairment improved at 2 g/day in Lopresti & Smith 2026 (PMID 41601871).PubMed →
  • Many adults don't get enough magnesium from food. This form helps top up your everyday magnesium. Your body uses this mineral for normal energy, nerve, and muscle function. Workinger, Doyle & Bortz 2018, Nutrients (PMID 30200431); Fatima & Hadi 2024, Cureus (PMID 39539878).PubMed →

What makes this magnesium different from a regular magnesium pill?
It's a special form called magnesium L-threonate (Magtein). Most magnesium forms don't reach your brain very well. This one is the form shown to reach the brain. That's why it's chosen for calm, clear thinking, and restful sleep — on top of the everyday magnesium your whole body needs.
What might I notice when I take it?
In studies, people had clearer thinking and better focus, and reported more restful sleep. Many also describe a calmer, more settled feeling. Everyone's different, and a supplement supports your body's normal function — it isn't a quick fix. Give it steady, daily use and notice how you feel over a few weeks.
Will it make me sleepy during the day?
It's meant to support calm and clear thinking, not to knock you out. In the sleep study, people kept good daytime function. If you're wondering about the best time of day to take it, your practitioner can help you fit it to your routine.
How much do I take, and when?
This product gives 2 grams in a 2-capsule serving, which matches the dose used in the studies. For how it fits you — timing, or if you take other things — check with your practitioner. They can tailor it to you and your other care.
Is this safe for my kid, or while pregnant or nursing?
Please don't guess on this one. Talk with your practitioner first. They know your child or your situation. They can tell you whether it's a good fit and what amount makes sense.
Can I take this with my other supplements or medicines?
Maybe — but it depends on what else you take. Some things can interact. Bring your full list to your practitioner and let them check it over before you start. That's the safe way to do it.
