As you grow older, your body becomes less efficient in absorbing important vitamins and minerals. So, despite a healthy diet rich in fresh organic vegetables, you may still come up short in certain nutrients. One such mineral is magnesium. Experts believe that as many as 80% of Americans don’t get enough. Because there are no reliable lab tests for magnesium, you have no way of knowing where you stand. Fatigue and weakness may be your only clues that you’re low!

Magnesium is essential for building both your bones, DNA and genetic materials. It also supports the body’s normal detoxification process.*

Delivering 2,000 mg of patented Magtein™ magnesium L-threonate, our Magnesium L-Threonate is the preferred form over other types of magnesium for several reasons, including...

  • Having superior absorption characteristics of any form of magnesium.
  • Having high-cellular penetration characteristics, allowing it to cross your blood-brain barrier and penetrate cell membranes.*
  • Significantly reducing GI discomfort , unlike other forms of magnesium that can cause gastrointestinal discomfort and loose stools, magnesium L-threonate does not act as a laxative.*

Plus, Magnesium L-Threonate does not contain any genetically engineered (GE) ingredients nor does it contain magnesium stearate, a form of magnesium that I don’t recommend.

Don’t allow yourself to be one of the 80% who may be running low, and order your Magnesium L-Threonate today.

    I've been taking magnesium threonate for for some time, mostly just before bed to help with my sleep. I like that it doesn't have all the fillers that other supplements in the market has.

    I recently started taking this supplement, but it's been difficult for me because the capsules are huge, and most of the time, they stuck in my throat for hours... 😫

    I have used Mercola magnesium threonate for years. I have tried other brands but I always come back to my Mercola three a day. There are no unnecessary ingredients. This form of magnesium does not upset my colon. It is rather subjective but my thinking is clearer when I take Mag Threonate. Lastly, I do trust Mercola.com to produce a high quality product and I have never been disappointed.

  • Thankful for Magnesium

    I used to suffer from cramps in my legs, not just the calves but in even odd places in my legs. Plus my feet were affected and any cramp ruins your sleep. When I take Dr Mercola's Magnesium regularly I do not have a problem with cramps. I take two pills in the morning and two in the evening. Thank you for sound information about Magnesium and providing a supperior product.

  • Magnesium L-Threonate

    I have been using this product for quite some time now and just discovered that it was doing me harm. I would have returned it but I don't see that option. the top of my head, very often, feels hot and achy. I have been having a lot of nose bleeds some of them were quite scary. Only by chance did I discover that this magnesium was the source when I got off vitamins for a while and then the nose bleeds stopped. I took some magnesium, 3 capsules as per the instructions, and that day had a nose bleed again and also the next 2 days. I liked that this magnesium did not cause any digestion problems as other magnesium products do, but it is just not worth the worry.
