Increase your brain’s magnesium levels to promote optimal cognitive function*


  • 1000 mg of the only type of magnesium that has been scientifically shown to significantly raise magnesium levels in the brain


Supports a healthy brain and memory*

In multiple randomized, double-blinded, placebo-controlled clinical trials, subjects aged 50–70 who took Magnesium L-Threonate showed improvements in overall cognitive ability compared to those who took placebo. Overall cognitive ability is a brain function score based on the individual’s memory (ability to learn and remember), attention and executive function (decision making and planning abilities).*

May facilitate learning and a relaxed mood*

Clinical trials have shown that Magnesium L-Threonate can increase synaptic density, which has profound implications on our ability to learn. As the brain stores new information by building networks of neurons and synapses are the connections that let the neurons talk to each other. Strengthening them (increasing the density) is critical to maintain the ability to learn at any age.*

Supports bone health and nervous system functions*

Magnesium is critical for your body to absorb the calcium required to fortify your bones. Its ability to increase synaptic density is vital to nervous system functions as it strengthens the communication network starting in the brain.*


About half the US population is deficient in magnesium. Modern agricultural practices deplete soil of magnesium, leading to less magnesium in the foods you eat. Many common medications also deplete magnesium levels. Multivitamins often contain less than 1/4 of the RDA and absorption varies greatly based on the form of magnesium in the supplement. If you aren’t critically low on magnesium, you only absorb about 30–50% of dietary magnesium. Your colon eliminates the rest, which is why magnesium is often used in laxatives.

Magnesium L-Threonate is the only compound shown to significantly raise magnesium levels in the brain and encapsulating it in liposomes helps more of this water-soluble nutrient absorb into your cells where it’s needed to support learning, memory, and relaxation. The phosphatidylcholine that makes up the liposomes combined with Magnesium L-Threonate is a powerful way to support brain health.*

Using patented technology, we wrap the Magnesium L-Threonate in double-layered spheres (liposomes) that protect the nutrient through the digestive system and transport it into the bloodstream for absorption in the cells.



1000 mg Essential Phospholipids

  • The same material that makes up your cells
  • Assimilates into cells with Magnesium L-Threonate intact
  • Derived from non-GMO soy lecithin

500 mg Phosphatidylcholine

  • Vital to healthy cardiovascular, reproductive, immune, and nervous systems*
  • Required to synthesize neurotransmitters for proper brain function*
  • Fortifies cell membranes to protect cell contents*


As a dietary supplement, take one packet 1 to 2 times per day or as directed by a healthcare practitioner (Magtein® recommends 2 packets per day in divided doses).

  1. Take on an empty stomach

  2. Tear packet at the notches

  3. Squeeze the entire contents of the packet into 1–3 oz. of a cool beverage

  5. Wait at least 15 minutes before eating

  6. We recommend consuming a full glass of water after taking the product

  7. Contents of packet will not dissolve

Do not mix the Lypo-Spheric® Magnesium L-Threonate with hot beverages or in a blender as this could damage the liposomes.

Store at room temperature. Do not freeze or place the Magnesium L-Threonate in direct sunlight for extended periods of time.

If you open a packet and do not consume all of it, place the packet in an airtight bag or plastic wrap and refrigerate up to 24 hours.


Magtein® may induce sleepiness, drowsiness or headaches. This may indicate a magnesium deficiency and is temporary. Reduce the dosage, consult a doctor, or discontinue use if condition persists for more than one week. Keep out of reach of children.

Brain booster

Definitely relaxes you and improves the brains ability to process more complex topics. It has same effect as being in ketosis to me.. I put gel on a spoon and wash down with water.

Great Stuff

I love this magnesium so much! It helps me sleep sounder. I am very magnesium deficient and feel like all of the other supplements out there do not absorb into my system. This stuff actually makes me feel good and there are no crazy additives either

The first time I tried these products felt amazing 😉

Yes I have Hperthyrodisum

I like this product a lot, but noticed that it has soy, Im not a huge fan of soy anything. I will try for 30 days and see how I feel. I eat many asian foods, mainly because my husband is Japanese and he loves to cook authentic Japaneses dishes. So far I noticed my thyroid is calmer and I sleep soundly and deeply, also my heart rate is not racing, as much.

I am alert and the brain fog is gone. I continue to ride my bike, swim and exercise better.

And I just turned 65.

Amazing affect on Parkinson's

After taking for just a couple days I felt a sense of calm come over me. The severe Ness of my restless leg diminished by about 70%. Much of my shakiness was completely gone. My stiffness and rigidity relaxed immensely and as I was walking my arms were swinging better than they had in years. I have not been sleeping for more than 2 1/2 hours at a clip for years I actually slept a couple of times for four hours and did not work with severe restless leg issues it was much much lighter and later. The only issue I had which cost me to stop taking it for a couple days is a severe drop in blood pressure which was already a problem. I am going to start taking it again but just about a third of a package. If you have any ideas on how better to do this please advise. Thank you so much for the relief. It truly is a godsend
