Improve your brain function with Magtein® L-Threonate, proven to increase synaptic density which helps memory, attention and learning focus.  Methyl-Life® brings you Magtein® in its purest form, without a single additive, an odorless and tasteless powdered form of magnesium.  We’ve hand-picked this innovative and highly bioavailable version of magnesium designed to enhance brain function in four different ways:  1) attention  2) working memory (executive function)  3) long term memory and  4) short term (or episodic) memory.  Magtein® crosses the blood brain barrier and has shown stunning results in human as well as animal studies.  It is protected by 8 US & international patents.

Magtein® recently demonstrated remarkable results in a human clinical study on dementia & Alzheimer’s published in the Journal of Alzheimer’s Disease.   It showed a meaningful increase of memory-related functions in the brain which represented a 9 year age improvement when subjects supplemented with Magtein® (5).  The study revealed that less synaptic density actually means more memory loss, which is why the mechanism of action for Magtein® seems to be so critical.  Magtein® essentially makes more synapses for the brain to use.  Synaptic density improves recall functions in the brain.  The findings concluded that as long as the nutrient was present, cognition got better, however, when Magtein® was removed from the participants’ daily regimens, the synaptic density was reduced and the memory impairments returned.

The main side effects were a substantial reduction in stress and anxiety.  In an animal model, it was noteworthy to learn that Magtein® enhanced the control of fear-stress memory – the brain regions known to control stress and fear actually improved with the nutrient (prefrontal cortex/hippocampus) (3,4).  In a rat study Magtein® was also shown to increase the learning ability of young rats in addition to improving their working, short and long term memories (1,2).

Methyl-Life® is very excited to bring you this revolutionary new magnesium for your own cognitive enrichment!

WARNING How much is right for you to take? Talk to your doctor about what’s best for you.

We spent a great deal of time on our formulations and believe they are optimal for a couple key reasons:

  • Superior form – We chose the pure powder form specifically to ensure the consumer could obtain a 100% additive-free product.  This form can be easily stirred into liquid (water, milk or juice).  It’s virtually odorless and tasteless, making it very easy to give to anyone.
  • Perfect ingredient – Our search to find an effective nutrient for improving cognition landed on this revolutionary mineral.  We have been impressed not only by the study results but also by its effectiveness in our own personal lives.
SUGGESTED USE:  take 1/2 rounded teaspoon stirred into liquid or as your healthcare provider recommends.
Serving Size: 2 grams (approximately 1/2 teaspoon)

check_mark_gray  What is the right dosage for me?

Most studies have found that 2 grams per day is effective for improving brain health by increasing memory recall, attention and learning functions.  And instead of having to swallow 3 capsules today, we’ve produced a form of the nutrient that you can easily stir into a liquid (and that has absolutely no additives whatsoever, it’s just pure, 100% Magtein® only).

check_mark_gray   Has Magtein® been proven effective?

Check out the published study in the Journal of Alzheimer’s Disease [Guosong, L., et al., Journal of Alzheimer’s Disease 49 (2016) 971–990].  There’s great science showing how this nutrient affected cognition and memory function equivalent to a 9 year age improvement.
