  • Description

As you get older, your body becomes less efficient at absorbing important vitamins and minerals. So, even when you eat a healthy diet rich in fresh organic vegetables, you may still come up short on some important nutrients. One such nutrient is magnesium.

Experts believe that as much as 80% of Americans don’t get enough of magnesium. Yet, this mineral is essential for vibrant health, playing a key role in the body’s normal detoxification processes. Your bones need it, your muscles need it, your nerves need it and your brain needs it.*

Delivering 2,000 mg of patented Magtein® Magnesium L-Threonate, Magnesium L-Threonate is the preferred form compared to other types of magnesium for several reasons:

  • It has superior absorption compared to other forms of magnesium.
  • It has the ability to cross your blood-brain barrier and penetrate cell membranes.*
  • It can reduce gastrointestinal (GI) discomfort. Unlike other forms of magnesium that can cause GI discomfort and loose stools, magnesium L-threonate does not act as a laxative.*

Magnesium L-Threonate offers many benefits to your mind and body, including support for your bone and joint health, nerve health, clear thinking and healthy sleep. Plus, our formula is made without genetically modified organisms (GMOs).

  • Constipation

    Found it caused me and my wife constipation. Stopped it and the constipation went away... Will have to try doing one more time to see if it happens again.

  • Better than other brands

    I purchased another brand when this was out of stock. It had the same type and dosage of magnesium. I started getting bad nightly leg cramps and having problems sleeping. I switched back to mercola magnesium and the problem was instantly resolved. This product is worth every penny not to get woken up by stabbing leg pains.

  • Odd Mildew Odor!

    Very disappointed as the bottle once opened had an odd odor... smelled like mildew. I did try them but decided best not to continue due to the foul smell. I expected much better from Dr. Mercola and would like a refund. I purchased th 270 capsule bottle.

  • Hard to swallow

    My husband finds these very hard to swallow. They either stick to the back of his tongue or gets stuck in his throat and water doesn’t always wash the capsule down so he has to cough it back up. Not sure if it is because of what the capsule is made of but he doesn’t have any trouble with any other supplements he takes in capsule form.

  • Love it!

    One of the best supplements you can take. I started taking this with B complex few months ago and for the first time since I was a toddler stopped biting my nails. Now my nails are long and strong and I have no desire to bite them. Still in shock!

  • Magnesium L-Threonate

    I've taken other Magnesium supplements from other manufacturers with little to no results. I have to say this supplement is pretty dang good. I sleep better at night too....and haven't had any leg cramps. Unfortunately, it's out of stock now....so not too thrilled about that. I hope it comes back in soon, because I hate migraines!!!!

  • Dr Mercola magnesium

    I have gone thru one bottle already. I can only say, it is pretty amazing, not to wake to excruciating legs cramps. I have taken other types of Magnesium that did not help me. Couple of times I could not walk, had to crawl to my bathroom in the night, to retrieve pain cream it was frightening. Now I use only Dr Mercolas products. Period.
