Why I Have a Vitamin D Deficiency? is a video looking at vitamin d deficiency and how much vitamin d is needed in order to be healthy. It is a topic with much confusion behind it as to exactly what is needed to be healthy and have sufficient vitamin D levels. Vitamin D side effects are often a concern but the reality is most people are not at high enough levels to have an issue. Vitamin D supplements are the ideal way to improve your vitamin D scores.

    High Dose Vitamin D Treats Incurable Diseases? https://youtu.be/dTNXqXWhxpI

  2. @henrikmadsen2176 on April 12, 2025 at 11:52 am

    Most of us are probably also deficient in Potassium. Rather high RDI, and most foods does not contain loads of potassium.
    I would love to know your opinion on this Dr. Nick 🙂🙏

    • @bobvalley2221 on April 12, 2025 at 3:32 pm

      The things that most people are deficient in are the things that are made almost impossible to get in modern times. Potassium, Magnesium, Vitamin D. So many normal health problems could be avoided if people understood this.

    What about liver oil?

    Most things I read said to take separate D3 and K2 supplements.

    I have always wondered why vitamin recommendations are not based upon the consumer’s body weight. Obviously a 100 Kg person would need twice as much of anything compared to a 50 KG person

    • @bkrpb3DDa4G3kzELoQGt on April 12, 2025 at 5:17 pm

      That’s because body weight is not the only factor. Vitamin D3 conversion to active Vitamin D (calcitriol) happens mainly in the kidneys. So kidney function is a factor. But the biggest issue is VDR blockage (Vitamin D Receptor).

      Many things can cause a person to have VDR blockages like infections, as well as genetic variances (SNPs) which cause some people to have less absorption of active vitamin D.

      So if someone’s conversion of D3 to calcitriol is LOW for some reason, then that person will need higher daily amounts of D3 to compensation for the lower conversion.

      So a 200 lb man may be put on 50,000 IU daily of Vitamin D3, while a 100 lb woman may be put on 100,000 IU daily if she has poor VDR function, etc.

      Dr. Coimbra uses 1000 IU per kg of bodyweight when prescribing his High Dose Vitamin D3 treatment, but that must be accompanied with a low calcium diet to prevent hypercalcemia during the treatment. And PTH and calcium levels must be monitored regularly.

      High dose Vitamin D3 can produce almost miraculous results with those people who’s root cause problem is vitamin d insufficiency.

      I wish people wouldn’t depend on institutes and studies, yet do what makes you feel good. Organizations trying to grade everybody on a curve is insanity.

    I find when I take Vit D it gives me acne.

  9. @chrisferretti7020 on April 12, 2025 at 1:13 pm

    I lost my gallbladder due to gangrenous cholecystitis; does this impaired my ability to absorb vitamin D? I never heard this before.

    • @dr.nickzyrowski on April 12, 2025 at 4:28 pm

      Vitamin D is a fat soluble vitamin. The gallbladder helps you absorb fats.

    • @bkrpb3DDa4G3kzELoQGt on April 12, 2025 at 5:27 pm

      The liver makes bile, which is then stored in the gallbladder. The bile emulsifies the fats so that they are more easily absorbed. Your liver still produces bile, but it slow drips it all day long, instead of being able to have a large amount at-the-ready like when you had your gallbladder.

      Without a gallbladder, you’ll need digestive support in the form of ox bile, with every fatty meal.

    • @lisd2999 on April 12, 2025 at 6:06 pm

      I have no gallbladder and my level is 108ng
      I take between 5 and 10k a day. Along with K 2 and mag

  10. @blahizake on April 12, 2025 at 2:10 pm

    I know everyone is different, but my vitamin D status is strong without supplementation:

    – working out daily in the sun with only board shorts
    – taking cod liver oil
    – eating egg yolks, liver, sardines, mackerel, raw dairy, etc.
    – cholesterol-rich foods in general, contributing to the pool of 7-dehydrocholesterol in my skin

    • @jm72309 on April 12, 2025 at 2:57 pm

      According to Weston Price Foundation, you should take 35 units per pound for your base. Add additional 2000 to increase if you are deficient

  11. @teresahunt5521 on April 12, 2025 at 2:16 pm

    Working in medicine is terrible for vitamin D levels. I’m literally never outside. I take 5-10k IU daily. I write rx for 50,000 IU weekly on a regular basis. . I still need to add some fat along with it. Thanks for the reminder.

    • @dr.nickzyrowski on April 12, 2025 at 4:25 pm

      Yes… I have the same problem. 12 hour days indoors.

  12. @Neil555-11 on April 12, 2025 at 2:23 pm

    Ive read that not only k3 but you need additional magnesium when taking large doses of vit D due to the interaction of vit D and Mg

  13. @bobvalley2221 on April 12, 2025 at 3:29 pm

    How is the optimum level of vitamin D determined? If it’s so important wouldn’t higher blood levels be even better? If you lived like our ancestors and basically spent all day every day in the sun what would your level of vitamin D be?

  14. @Sheryl-s8q on April 12, 2025 at 3:43 pm

    When you are low and have been tested for vit d and winter no sun to soak up low vit d , perimenopause you need vit d daily , and if you are low your body will let you know

  15. @user-dx7gq8yg3e on April 12, 2025 at 3:53 pm

    …..besides K2, there is also a relationship between Vitamin D and Vitamin A, Magnesium, and Calcium levels. Deficiency in these nutrients could also impact the efficacy of Vit D.

  16. @mindfulmaximalism on April 12, 2025 at 4:36 pm

    I grow and weed a big garden in my bathing suit. My neighbors think I’m a hippy, but I get my vitamin D (in addition to a lot of organic food).
