Not many people know about magnesium L-threonate.
I think it’s arguably one of the most important forms of magnesium to address overall deficiency, although I never rely on just one form of magnesium. Taking a holistic approach and using both the oral and transdermal form is my jam.
More specifically..
Magnesium glycinate
Magnesium chloride
Magnesium sulfate
Magnesium taurate
What makes magnesium L-threonate particularly interesting is the effect it has on the brain, working memory, learning, so forth.
It’s a cognitive booster which is why I labeled it as a nootropic.
Magnesium L-threonate was developed by a team of neuroscientists at MIT and Tsinghua University in Beijing. They bound magnesium to L-threonate, a vitamin C metabolite.
Since then, it’s proven its excellence.
Passing The Blood-Brain Barrier
A hallmark of this form is its ability to bypass the blood-brain barrier.
Yes, this barrier is a crucial safety mechanism which evolved to protect your brain from various external invaders. But this form of magnesium is not toxic to the brain. It helps improves a number of mental metrics.
Increased Brain Plasticity
It’s been shown to increase brain plasticity which is fantastic for memory and learning.
Relatively New Creation
Magnesium L-threonate has only been around since 2010.
Potential To Treat Neurodegeneration
Low magnesium has always been linked to Alzheimer’s and dementia.
It can also prevent memory loss and mental decline in aging rats.
On Finding Magnesium L-Threonate Supplements
Few magnesium supplements on the market contain this form of mag unless you’re buying an option specifically dedicated for it.
You must check product labels carefully to make sure that your supplement contains it in adequate levels.
It’s available in its generic form, but there’s one brand name you can look for which is Magtein. This is a patented form of magnesium L-threonate that’s been well studied in animals.
It’s a raw ingredient included in magnesium formulations from a handful of companies like Magceutics, Jarrow Formulas, NOW, and Source Naturals.
Worth noting that this form of magnesium is more expensive.
My personal go to is Cymbiotika’s Magnesium L-threonate.
I’ve noticed an increase in mental performance, focus, and an ability to get into flow more easily while on their mag L-threonate. Highly recommend.
Dosage
There’s no set RDA for magnesium L-threonate.
Aim for 1500-2000 mg per day as a rule of thumb.
In the study linked above, subjects took 1.5-2 grams per day.
Only a fraction of mag threonate is elemental magnesium. 2,000 mg delivers only 144 mg of elemental magnesium which is why I don’t solely rely on it to fix general magnesium deficiency.
Getting your health in check can be overwhelming. I’ve seen many men buy a shit load of supplements, only for me to tell them most of it is useless.
