9 Signs of Magnesium Deficiency & Quick Fixes – Dr Mandell

Magnesium is the most important major mineral that is needed by your body.  In order to function correctly and efficiently, your body needs many nutrients.  However, if it is deficient in magnesium, there are over 350 biochemical reactions that either will not occur at all or will occur very inefficiently.

    Yes, I started taking Magnesium Citrate along with Zinc for Menopause Symptoms. I have to say, it works absolutely bloody brilliantly. I get the odd flushing but I’m good!

  • Steven Cartwright

    Can magnesium be taken through the skin (externally), as in bath salts?

      Iluv Merengue : Simply because soaking in Mg Sulphate is detoxing, whereas we use Mg Chloride “oil” to rub into our skin, the body’s largest organ, in order to increase our Mg levels. Many people prefer not to absorb that which they’ve just detoxed from. Both forms are good, just preferably not simultaneously. Only about 5 forms of Mg are not beneficial. Citric acid depletes ceruloplasmin.

      Steven Cartwright, Epsom salts is one of the ABSOLUTE BEST ways to get magnesium. It is absorbed directly into the bloodstream through your skin!! Magnesium is a great way to lower cortisol, destress and relax. It also helps dislodge aluminum and other toxins from your cells..2 molecules of magnesium to dislodge 1 partical of aluminum. Just make sure that you use a chelating type of herb/plant….kelp for example, in your diet to help pass it out of the body…otherwise, your intestines will just reabsorb the toxins/aluminum. 🙂

    I wish you had a very brief write up about the symptoms and solutions for magnesium deficiency. Some people are just lazy to watch a nineteen minute video. I’ll put in the effort to translate that into Arabic, and broadcast it to my whatsapp contacts. Very informative and eye opening. Keep it up, doc

  • Kimberly Flaherty

    Thanks for such an informative video!

  • Joanne DeHerrera

    My husband has high blood pressure, but he craves bananas like women on their monthly crave chocolate.


      He probably has low potassium….tell him to eat an avocado instead of bananas….they have almost 3 x as much potassium as a banana. We need 4700 mg of potassium per day. 98 percent of americans are LOW potassium.
      3 avocados per day will do the trick but watch other carbs in that case. Each avocado has 12 gms of carbs..

    I’ve seen studies that show it’s good for after concussions as in car accident under a Dr supervision to help with ringing in the ears. Wish I knew that sooner but it has seemed to help lower the ringing volume in my ears.

  • Kimberly Flaherty

    I love the product called “Calm” ……it’s a magnesium supplement that my daughter turned me on to when I was suffering terrible cramps. I would usually have them at night…..in my calves, feet/toes and the worst ones were under my ribs. I NEVER get them anymore as long as I take Calm. Another great thing I noticed is that it keeps me regular!

  • Hileni Ndapewa Tjivikua

    If black beans give you gas just cook them with ample cumin. It counteracts it. I sneak beans into my boyfriends food, he has no idea…but if we eat beans at a restaurant or somewhere without cumin he bloats really badly. It works!

  • Martin Pickering
