Magnesium and Heart Palpitations

Posted Oct 25 2008 4:48pm 1 Comment


Dr Ben -

I see that your site offers a variety of magnesium supplements.  I am currently pregnant and have been experiencing heart palpitations.  My midwife told me to take magnesium.  I have been taking [Brand X] 250mg pills, but I don’t think I’m absorbing as much as I should because I am still having palpitations before my next dose.  So, my question is which of your products will best suit my needs?  Thanks so much for your time.  I look forward to hearing from you.



Magnesium is a tricky one and companies typically use poor forms of magnesium as it is less expensive to produce. The magnesium supplement you are taking contains poor ingredients. Magnesium Oxide , Cellulose Gel , Croscarmellose Sodium , Magnesium Stearate.

Magnesium Oxide is the worst form of magnesium to take as it has the least absorption. To make it worse, Nature Made magnesium is in tablet form making absorption even less.

You may consider doing a few things to enhance absorption:

  • Mag Phos 6x 1000 tab cell salt works on a more cellular level than the typical magnesium supplement. It is easiest to put 25 tablets in 1 liter of water and drink throughout the day - every day. This way you are getting water and magnesiumm - both key to proper health.
  • Low electrolytes may cause numerous symptoms and taking the full range may assist in reducing palpitations. The recommended dosage of E-Lye Electrolyte Concentrate is ½ an ounce of concentrate to 8 oz. of water, or 8 ounces into 1 gallon of water or milk. Drink an 8 oz. serving 1-2 times daily, or as directed by your physician or HCP.Add this to the 1 liter of water and drink throughout the day along with the Mag Phos cell salts making it easier for you to remember.
  • Taking additional Magnesium of one type will likely lead to diarrhea or GI upset. So it is recommend to take a product with 3 forms of magnesium in it for optimal absorption. Tri-Magnesium offers this. Recommend dose is 1-2 caps per day.

I would use this product over the [Brand X] product. I would actually throw the [Brand X] one in the trash. I do not see how it can provide much benefit given the ingredients and tablet form.

These three may reduce your heart palpitations if it is due to a magnesium deficiency.

One thing to keep in mind:
Magnesium and Calcium compete with each other. So make sure you are consuming products high in Calcium - like Organic dark leafy greens and Chia Seeds. Just two ounces of Chia seeds contain 600 mg of Calcium, compared with 120 mg for milk.

If you’ve further questions, please do inquire.

Have a healthy pregnancy and enjoy your little one when they arrive :)

In health,
Dr Ben
