Dr. Mercola Magnesium L-Threonate

Every year comes with more candles on your birthday cake, more reasons to celebrate, and more memories to cherish. Yet even when we’re healthy, our bodily functions slow down with age — especially the ability to absorb and maximize nutrients. This is particularly true with magnesium levels!

Magnesium is an essential mineral, element, and electrolyte. More than 90 percent of your body's magnesium is kept in your bones and muscles; the rest remains in your blood. It plays a crucial role in muscle function, maintaining blood pressure, optimal brain health, balancing insulin levels, reproduction, and more.* In fact, your body utilizes magnesium for more than 300 essential processes!

  • Preserves muscle function*

  • Encourages better quality and duration of sleep*

  • Aids heart health and blood pressure*

  • Boosts brain function and eases occasional headaches*

  • Maintains insulin levels and detox processes*

  • Supports reproduction*

  • Enhances physical fitness and endurance*

  • Stimulates a healthy inflammatory response*

  • Reduces symptoms of occasional anxiety and depression*


Recent scientific studies have shown that approximately three-quarters of Americans may have a magnesium deficiency. Symptoms include headaches, weak bones, insomnia, poor absorption of nutrients, mood imbalances, or muscle weakness.* Most people experience extreme brain fog, fatigue, and sleep troubles.

Thankfully, there is a simple solution so you don’t have to suffer through a magnesium deficiency! An extra absorbable magnesium supplement like Dr. Mercola Magnesium L-Threonate is your ticket to health!


  • Benefit your bones with a steady supply of magnesium! After all, nearly all of your body’s supply of this mineral is stored in your skeleton.*


  • Calm your mind and body every night before bed by taking a daily magnesium supplement. This mineral naturally soothes a busy brain and tense muscles so you can fall asleep and stay asleep.*


  • A dietary supplement like Dr. Mercola Magnesium L-Threonate stimulates your body's natural detox pathways to remove toxins from your system.*


  • All of us could use an extra energy boost these days! Magnesium delivers more energy, starting at the cellular level.*


  • Relieve headaches and foggy thoughts by nourishing your brain cells with magnesium L-threonate. Unlike magnesium citrate, it has the special ability to cross the blood-brain barrier for advanced brain health.*


  • This magnesium supplement can even increase your antioxidant capacity! Your body requires magnesium to produce glutathione, "the master antioxidant."


  • Since magnesium also functions as an electrolyte, it stimulates and protects nerve health, nerve transmission, and nerve function.*


Dr. Joseph Mercola noticed how many magnesium supplements on the market were tough for the body to absorb and fully utilize. That’s why he formulated this high-quality mineral supplement! Many supplements will include “elemental magnesium,” which is actually quite difficult for the body to absorb. However, magnesium L-threonate outperforms all other types when it comes to absorption!

  • Contains 2,000 mg of magnesium L-threonate

  • Most absorbable form of magnesium*

  • Better ability to cross cell membranes and the blood-brain barrier*

  • Causes less digestive discomfort*

  • Does not cause laxative effects like magnesium citrate*

  • Does not include magnesium stearate

  • Superior non-GMO ingredients*


Many fortified foods from the grocery store include a variety of vitamins and minerals. However, it’s best to pair Dr. Mercola Magnesium L-Threonate with magnesium-rich foods for a healthy lifestyle balance! You can get magnesium from foods like:


  • Greens: Make Popeye proud by eating more meals with kale and spinach.


  • Herbs: Season your food with fresh cilantro, basil, or parsley.


  • Nuts and seeds: Munch on a nutritious snack of pumpkin seeds or cashews. Or sprinkle flaxseeds over your yogurt, salad, smoothie, or oatmeal bowl.
