View the Show Notes For This Episode:

Magnesium is a critical mineral that is responsible for more than 600 enzyme reactions in the body, yet most people are not getting enough of it. Magnesium is critical for your cells to make energy, for many different chemical pumps to work, to stabilize membranes, and to help muscles relax. Essentially, anything that is tight, irritable, crampy, or stiff—whether it is a body part or even a mood—can be a sign of low levels of magnesium, and magnesium deficiency has even been linked to inflammation in the body and higher CRP levels.

In today’s episode of a new series I’m calling Know Your Numbers, I dive deep into magnesium. I discuss why millions of people suffer with undetected magnesium deficiency, how conventional medicine misses the mark in measuring magnesium levels, how Functional Medicine treats magnesium deficiency, and much more.

You can test your magnesium levels with Function Health, a company I co-founded. It has been a lifelong dream for me. Function is the first-ever membership that includes 100+ lab tests and personalized insights from globally renowned doctors based on your results. Join Function at .

    I started magnesium glycinate 2 weeks ago because I have had insomnia for 4 yrs. I just developed low high blood pressure after my whole life having low blood pressure. I am taking 300 mg 1 hr before bed. I also live in chronic pain with a cut spinal cord & several herniated discs from a major car accident 25 yrs ago. Thanks for everything you do to bring us to optimum health!🙏🙏🙏

    I take a multi-magnesium supplement. I didn’t realize there were 8+ different types of magnesium. I do sleep like a baby when i take it at night.

  • @blessingcarnes3110 says:

    My magnesium test says 2.2… should I still take a supplement? And how much?

    Any thoughts on how magnesium deficiency can be exacerbated after traumatic brain injury? No one is connecting the dots between the symptoms that can’t be confirmed by imaging and nutrient deficits or nutrients not being bioavailable, I.e, can’t make it to the bloodstream and brain cells.,hypoxia..

  • @freyadog5665 says:

    Magnesium at night gives me insomnia, body is relaxed, mind is fully awake. So I take magnesium in the morning and some calcium at night. That way I sleep very well.

    • @jenniferleibig1901 says:

      Thanks for this information. I think I may have the same issue.

    • @freyadog5665 says:

      @@jenniferleibig1901 welcome, I’m glad I came across a video about Magnesium on the channel “Kick It Naturally”. Helped me find that out, after having trouble sleeping for like a half a year.

  • @lisahause8705 says:

    I had about 5 of those symptoms…4 of them went away, after taking magnesium , potassium & adding sea salt too! Need them electrolytes!!!🥳👍🏻

  • @arughaogisi2249 says:

    Thank you for this critical information you provided in this video as you always do in your video. Stay blessed.

  • @2Worlds_and_InBetween says:

    I’ve had quite a good response to taking a Magnesium (with vitB&C) supplement this last few weeks,
    I remember years back when I was eating processed /fake foods, having an 18:32 ok result with Mg for pins & needles in my hands and other things.

    but this time Im sort of shocked at what a week or two has done for my overall wellbeing/symptoms.

    I did think I would have been getting enough of it from my diet,
    but I wonder if I was very much lacking in Mg that all the processes its involved with were ready to go… just not having enough to kick start the regeneration processes into high gear
    getting it over the crest of the wave so to speak and allowing my body /cells to really get working as best they can.

    a perfectly timed video
    must say, I am grateful, cheers

  • @juliegerdman5063 says:

    I drink calm at night. Wondering if this is a sufficient magnesium supplement or should I take more?

  • @dfinite4089 says:

    Thanks for this video, too, on magnesium.

  • @Jg-ej8zs says:

  • @justdawndb says:
