#1 Vitamin Deficiency in ALL Autoimmune Conditions

0:48 Parathyroid hormone and calcium
3:18 The Coimbra protocol
3:35 Vitamin D resistance
6:05 How to prevent high calcium levels in the blood

In this video, we’re going to talk about the critical roles of vitamin D and parathyroid hormone in helping to prevent autoimmune diseases. Many people with an autoimmune disease have had success with the Coimbra protocol, which involves taking high doses of vitamin D.

The Coimbra protocol checks parathyroid hormone levels produced by the parathyroid gland, which is intimately involved in calcium regulation. If you have low calcium, the parathyroid gland pulls calcium from your bones and distributes it into the blood. Vitamin D helps with the absorption of calcium by a factor of 20x!

Vitamin D resistance occurs when the body does not absorb vitamin D. You can have normal vitamin D levels in the blood yet still be deficient in vitamin D. Parathyroid hormone levels can tell you if that's happening.

If you are not getting enough vitamin D, you will have trouble with calcium absorption. The parathyroid gland will have to overcompensate to combat vitamin D resistance.

Usually, if you have high vitamin D, you’ll have low parathyroid hormone levels. Low vitamin D and high parathyroid hormone levels can signify vitamin D resistance.

If you have vitamin D resistance, the solution is to take more vitamin D! The Coimbra protocol involves adjusting vitamin D until the parathyroid hormone lowers to a low to normal level.

Vitamin D resistance is typically caused by a problem with vitamin D receptors or a genetic issue known as polymorphism.

Other barriers to vitamin D absorption include:
• Low sun exposure
• Darker skin complexions
• Old age
• High stress
• Location
• Air pollution

Pathogens have strategic methods of downgrading vitamin D receptors. Pathogens from tick bites can downgrade your receptors by a factor of 60x!

Cancer cells, especially those affecting the colon and bones, downgrade vitamin D receptors to survive. Heavy metals can also downgrade vitamin D receptors.

Magnesium and zinc can protect against high calcium levels in the blood, but your best defense is vitamin K2.

    I had high calcium in my blood and the resident at the hospital where I went in to the ER thinking that I was having heart issues told me I needed to look into it. I went online and started researching it and found the Norman Parathyroid Clinic in Tampa FL. Long story short, I went to their facility and found that I had developed a parathyroid tumor, and they did a minor surgery, and I now take K2 and Vitamin D together daily and all of my labs are back within the low normal range on my labs. I had not been feeling well ( lots of stress at work ) and death of parent and so grateful the resident pointed me in the right direction!

And this is the first time hearing about this. The video didn’t really say how much Vitamin K to to actually take and I’m worried that I might take too much vitamin D which can lead to hypo or hypercalcemia but I guess maybe if you take enough vitamin K the calcium doesn’t get stuck is the point? I know you’re not a doctor so I won’t hold your responsible, but I was just wondering in your case whatyou think is a good amount to take and for how long. Thanks.

    I keep commenting on this because I hope it will help others. My mom avoided the sun for years. She wore wide brim hats, long sleeve shirts, and sunscreen.

    Later in years, she developed Sjogren’s Syndrome (SS), an autoimmune disease, that triggered Multiple Myeloma (MM), an incurable slow growing cancer. She also suffered from Osteoporosis, Raynauds, bone & brain tumors. Not one case of MM has ever been cured by chemo. Chemo k*l led her, not the cancer.

    Following her lead, I too avoided the sun. I also have Sjogren’s Syndrome. If I knew what I know today about diet and supplements, my mom may have had a better quality of life or at least avoided triggering cancer. She did eat organic most of her life, but sadly it was all high carbs. During the summer each year, we would eat pounds of fruit from local orchards and berry farms each day.

    Great info! Far too many people are unaware of the importance of proper parathyroid function. So many, in fact, that there is basically a place close to where I lived in Atlanta, GA that does parathyroid tumor removals every day, all day long, on an outpatient basis. I was one such patient.
    My doctor kept saying my calcium was normal at 11.2 and Vitamin D was low at 8. So she gave me a Vitamin D prescription, and my calcium continued to climb, so I stopped the D and went straight to an endocrinologist/surgeon.
    I asked that he do blood tests himself, and he suggested expensive imaging tests instead. I told him to please do the imaging depending on the bloodwork. Results were the same: Dangerously low Vitamin D to safeguard the body against dangerously high calcium. Apparently, the human body is well-aware of what too much calcium can do and treats excess like a poison by eliminating vitamin D.
    He said, “And here it is,” pointing to a spot on the computer image. “This won’t look like much of anything to you, but you have a good-sized parathyroid tumor.”
    Rogue parathyroid glands strip calcium from the bone all day long. They go haywire after a very long period of Vitamin D deficiency (working in a cubicle), straining and stressing themselves to provide the blood with enough calcium, until at some point, they get stuck in a switched-on position.
    The surgeon told me the only option, at that point, is surgery. They don’t shrink back down after a decade of growth like mine had. The procedure is very simple, and chances of a second tumor occurring are less than 10%.
