Introducing Chris Masterjohn Lite

Magnesium is needed for literally everything in the body. When you don’t have enough, the most common problems are twitching, muscle cramps or spasms, heart palpitations, and weakness, plus other signs and symptoms discussed in the video. In this episode, I teach you how to look for its deficiency, how to use three different lab measurements to monitor your magnesium status, and how to fix a problem if you find one.

  1. Hi Chris, thank you for this post. I take upwards of 1 to 2 grams bis glycinate mg a day.. low when not working physical and the higher end when working during summer months. I used to be a heavy drinker. Stopped 10 yrs ago. Muscle cramps at night started 3 yrs ago. My naturopath did hair analysis showing lower calcium than mg status this year. Any tips on helping absorb mg? Seems like a bottomless pit I’m trying to fill.

  2. Hi Chris,
    I’m trying to figure something out. Will there ever be a physiological reason for why everytime I eat a food even moderately high in magnesium I get a headrush? It feels like I’m bottoming out like low blood sugar and I get panicky. I am a healthy 34 year old woman who likes to run and I am at a normal body weight. I just don’t know which direction to go because I know I’m probably severely deficient because of all the muscle twitches I get all the time. Thank you for anywhere that you can point me, I really trust your advice.I’m about to go to the doctor and ask them if they can test my magnesium and then ask them exactly the same thing but I’m not sure if they are as well versed in the biochemical reasons for certain reactions.

  3. Awesome stuff! I have a question if you don’t mind. I have a magnesium supplement that contains “Magnesium bisglycinate/Magnesium oxide 560 mg Providing Elemental Magnesium 100 mg.” Not sure how to dose this, go by the first number or the elemental number? Thank you!

  4. My 11yo son has had benign rolandic seizures for the past 2 years. (It’s not epilepsy, it happens only during sleep, and you outgrow it by 15.) After observing him for the first year, I noticed his seizures *always* come after sleep deprivation. He wakes up at 7am no matter what, so if he stays up past 9:30, he will have a seizure either that night (if he stayed up way too late) or the next (if he stayed up a little too late both nights). The seizures almost always come between 5 & 6am. He has seizures on average once a month, but much more often when we don’t work really hard to help him have enough sleep.

    After taking notes for another year, I noticed he always has a migraine the next morning (and never otherwise) for about 6 hours, his description of what precedes the seizure is exactly like a migraine aura, and he also almost always has leg cramps on those days, as well. I decided to supplement him with magnesium citrate that we had on hand, and he’s been taking 1T daily for the past month. Last week he was up till almost 10 every night, and one evening he was in a physically low mood (often precedes seizures), couldn’t sleep from 2-3 or from 5-5:30 and still didn’t have a seizure the next morning. I was shocked. He was up till almost 10 again that night and still no seizure the next morning.

    Do you think there is any possible mechanism by which magnesium can prevent seizure activity, or Mg deficiency can lead to seizures? His pediatric neurologist asked him a lot about migraines because he thinks there may be a correlation in some children, but he didn’t seem to know about kids where migraines happen immediately following the seizure, that is, where there is a direct cause-and-effect relationship between migraines and seizures.

    Second, I’m thinking of switching to magnesium glycinate when I run out of Mg citrate. Is there any reason one or the other would be better?

    Thank you!

    1. Certainly, deficiencies of any of the major electrolytes would produce seizures if they are very extreme. Follow my MWM class, I’ll be doing a few episodes on seizures soon.

      1. I would love to see your seizure episodes. I have a teenage friend who is having them, with headaches, but the docs could not find anything wrong.

        1. I’m working on them for MWM right now. It will be a month or so before they are all together and they’ll be up first on MWM Pro and then come out for free at the end of the year.

  5. I hope my doctor will use this information to investigate my need for large doses of MgO plus requip (ropinerol) to control restless legs and other unwelcome muscle activity.

    Thank you very much.

  6. Thank you for the information! I was so depleted of magnesium at one time, (stress), that I couldn’t function. Everything shut down.
