Vitamin D Caution You Need to Know


I am so excited to share this Facebook Live and THESE POWERFUL PEARLS with you.  At SAFM we are always revising our content in light of research findings.   Vitamin D, HDL cholesterol, Zinc, Vitamin C… There are many positive substances that savvy practitioners know about and emphasize. But More of a good thing is not Better!  And might be harmful.

Check out this video to get some clinical pearls you can use right away.  You’ll learn:

  • Why high Vitamin D can be dangerous (you will be surprised!)
  • What critical cofactors must be taken along with Vitamin D
  • Why high-dose supplementation may be counter productive
  • Surprising research insights into vitamin D and optimal levels
  • Weekly mega-dose or daily moderate dose: does it matter?
  • Why blood levels may not budge after supplement use

Please add a comment below to share what most resonated with you in this video, I am very interested in what you think.

Thanks very much for joining in the fun and learning! Congratulations to Anna Bush for winning the free seat to our next Core 101 Semester starting in January (a $2,200 value) we gave away after the video. Woohoo!


With warmth, love, and gratitude to you for sharing your gifts with so many –

      Thanks for your interest! Alas, the video and this page are indeed working fine. Your issue is likely an issue with your internet browser. We recommend you open a new browser window, maximize it, so the video frame is fully within the window, and click play. The volume icon is at the far right corner of the frame footer.

    I also want to add one more link that is a meta-analysis, but it’s a powerful one to help us begin to question whether low 25-OH Vitamin D is actually a *marker* of disease (that is an outcome) vs. a driver of disease. This is a key concept for us to consider!
    So much of today’s clinical research conclusions (and headlines! which highly influence our patients and clients) are those derived *via association* and not by deterministic study . 1-25-OH Vitamin D is the final active form, but we measure its precursor 25-OH Vitamin D in nearly all labwork because it’s a more stable and convenient marker to assess. However, I believe the next decade will show much more research into the concept that higher conversion of 25-OH to 1,25-OH Vitamin D (which leaves lower levels of 25-OH measurable in the blood) is a tenet of disease. We shall see! But at the very least, we should be casting a critical eye on the headline-driven assumption that “more and more is better” for Vitamin D. Indeed, my experience is that this hypothesis is actually *never* true in the human body. We are always seeking balance within our organism that is highly evolved with astoundingly complex feedback and regulation systems.

    Hi Tracy,
    This is great information and makes lots of sense.
    Are there any links to research or articles that discuss this?

    Both my daughter and so in law are suffering from valley fever. They live in Phoenix Az. We are going to do the organic honey and garlic, b complex, vitamin c, and whatever else I can find. They are in Az. Do you think they need to supplement with vitamin D or just add magnesium??

      Indeed, there is no way to gauge what you ask via a general reference. Alas, living in a very sunny place with lots of regular sun exposure does not mean one isn’t actually deficient in Vitamin D. In cases like these, it’s critical to get labwork to understand what a unique body needs. I recommend Vitamin D, Vitamin A, and RBC Magnesium blood markers.

    Thankful for all these videos. My take away pearl today was how magnesium needs to be sufficient in order for Vitamin (hormone) D to be effective.

    As always, you always learn new things with tracy:)
    Even though I am student, and have learnt many key points discussed in this video, I still keep on learning. I learnt the following: before you begin to supplement with D make sure the Mg is in good standing. Make sure to take D3+k2 +mg and if taking Ca as well because they all work together- Always check the levels before you begin supplementation. Make sure that they are digesting their fats properly or else they will not be absorbing vit. D or its cofactors so look into that properly. I loved the new RR makes a lot of sense 40-50. Something I will begin to keep a look out for. If someone has an AI then we should boost to 60-70-80 for triage but then lower it down(no one ever mentioned that before) because it suppresses the innate immune system. We should look into other factors of bacterial imbalances that might be playing a role as well so we want to give the immune system a chance to fight vs. suppress it with high D levels. .
    To avoid the blues in countries that don’t have sun, one should supplement w D and fish oils but always when you supplement you should titrate the quantity gradually and not give it in one big dose to open up the receptors to receive it vs. flood the system . Remember that Vitamin D is an actual hormone in itself so it will effect estrogen- so be aware of the dynamics at play.
    Lots of pearls tracy- Thank you

    Excellent and interesting information as always. I tried the link…but it wasn’t working for the few hours I tried last night. You’re team wrote me to send this new link…so hope I can still be entered into the drawing. I learned that high doses of Vit D decrease autoimmune responses and suppresses our innate immunity. Happy Holidays and keep them coming!

    Great information about vitamin D.
    Two things I did not know was due to the angle of the sun in the wintertime, vitamin D absorption is difficult or very weak.
    Also, high levels of vitamin D are not good for people with autoimmune disorders.

    Good Info!!

    Hi I tried to comment on the video on vitamin D but it didn’t go through, I would love to have another opportunity to get a chance to win a subscription. I really like tou work and take on health thats different that other practitioners and courses. Thanks so much for everything you do we need this in our community.
    All the best

    Excellent information as always! Many pearls: Vitamin D is important for regulating the absorption of Calcium from the GI tract, cofactors to consider – Vitamin D and A work in tandem, We are not what we eat: we are what we digest and absorb, Vitamin D is fat soluble. Thank you again for a great presentation and valuable information.

    This was my first webinar, Thank you! Great information.
    Thank you for sharing most recent research indicating
    That Vitamin D should be raised gradually so as not tonegetiveky
    Affect immunity.
    Looking forward to hearing more!

    I always wondered about the link between magnesium and Vit D, but the other part I found very interesting is the connection with excessive Vit D and how it suppresses the immune system which would cause improvements in autoimmune conditions. However, it makes complete sense as to why you need to determine if parasitic infection, fungal, viral infections etc. may be the link as to why an individual may have the autoimmune condition to begin with. Therefore, the excessive Vit D in the short term may appear to cause improvements in overall health, but in the long run won’t. Thank you so much for sharing this. I found it extremely helpful!

    Hi Tracy, As a fellow reader of Life Extension cover to cover, I’ve been keeping my Vit D blood levels around 80.
    I will now aim for 40 to 50, thank you!!!! Sharen Becker

    Heidi Hudson says:

    Curious to find out if any Vitamin D2 at all gets converted to the correct usable form?

  17. 144

    Thank you for this! I found two areas particularly interesting – use of short term higher levels of D to triage auto-immune and dropping to deal with infectious processes. Could ask so many questions… also the link between increasing D and hot flashes. Have seen some young women (20s) with flashes and have another area to think about now with so much supplementation.
    Wondering what you think about the IFM hand out with specific levels, now thinking about one size does not fit all?

    Monica Medrek says:

    I learned some pearls! Excessive vitamin D can suppress the immune system. I didn’t realize this. Also one with autoimmune issues may need to decrease vitamins D levels to fight the infection.

    Heidi Hudson says:

    Loved the informative video about Vitamin D! I thought it was really interesting to learn that Vitamin D supplementation for someone with low or fluctuating estrogen levels vs someone that is estrogen-dominant can have such opposite effects on hot flashes. I also found it fascinating to learn about the co-nutrients that are involved in keeping our Vitamin D levels at the correct level.

    Wondering if too much Vitamin D can cause kidney stones?

    Would love to win the tuition!

    I find it fascinating that excess Vitamin D can suppress the immune system. The entire lectures was just so interesting and so educational. I would love the chance to study more topics like this. Thank you Tracy for the opportunity!
