Dr Mercola Magnesium L-Threonate

Dr Mercola

Dr Mercola’s Magnesium L-Threonate is a high-quality, high-absorption formula which delivers 2000 mg of patented Magtein‚ Magnesium L-Threonate, including 144mg of elemental magnesium, in 3 powder dose capsules.

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 be short in certain nutrients. One such mineral is that of magnesium. Magnesium is essential for building both your bones, and your DNA and genetic materials as well as helping your body detoxify.

With Dr Mercola’s Magnesium L-Threonate you can have a high-quality magnesium supplement with superb absorption that animal research suggests can cross the blood-brain barrier and penetrate cell membranes. It’s one of the most practical ways to help balance your overall intake of this vital mineral.

Contains Magtein, the only magnesium compound that has been shown to effectively raise the brain’s magnesium levels. It also significantly reduces GI discomfort unlike other forms of magnesium that can cause gastrointestinal discomfort and loose stools.

In addition Magnesium L-Threonate does not contain any genetically engineered ingredients nor does it contain magnesium stearate, a form of magnesium not recommended.

So why is Dr Mercola’s Magnesium L-Threonate so good?

  • Avoids magnesium stearate – Magnesium stearate is not a source of magnesium. Rather, it is an unnecessary processing aid with no nutritive value, so you should avoid it.
  • Delivers a high-absorption formula – It‚ is not just about the amount of magnesium found in the supplement. The formula must have high-absorption capabilities. Magnesium L-Threonate has superior absorption characteristics to any other form of magnesium.
  • Incorporates high-penetration characteristics – Absorption of magnesium is crucial but it‚ is also important that the nutrient is capable of penetrating key tissues and cells to be effective. It has high cellular penetration characteristics to allow it to cross your blood-brain barrier and penetrate cell membranes.
  • Helps avoid potential discomfort – Many magnesium products are used as laxatives and antacids. Since this is not the primary focus of what we consider the ideal magnesium supplement, we recommend avoiding any that are specific to stool-softening and so-called indigestion aids. This product significantly reduces GI discomfort, unlike other forms that can cause gastrointestinal discomfort.
  • Provides practical, easy-to-take servings – Supplement servings must be practical to fit into anyone’s busy schedule. Serving size should be straightforward with well-defined guidelines.

Why you don’t want to be short on magnesium:

  • It is the fourth most abundant mineral in your body
  • Exists in over 300 different bodily enzymes
  • Is found primarily in your bones (half of your total body magnesium)
  • Plays a role in your body’s detoxification processes
  • Aids your energy metabolism and protein synthesis
  • Helps guide a large number of physiological functions
  • Is required by glutathione (the “master” antioxidant) for synthesis
  • Is especially valuable for supporting your brain health

So how can you know if you are getting an adequate supply?

Some early signs of a potential lack of magnesium in your body include…

  • Loss of appetite and headache
  • Nausea and vomiting
  • Fatigue and weakness

As you can see, many of these symptoms are pretty general and can result from a variety of different conditions. If you suspect you are low in magnesium, your first course of action is to consult with a healthcare professional.

Suggested use – Adults, as a dietary supplement take three capsules daily, two at mid-day and one at night, 2 hours before bed.

If you are nursing, pregnant, taking medication or have a medical condition, consult your physician before taking this product.
