Many people believe that as long as their blood test shows "normal vitamin D levels," everything is fine. However, what truly determines the body's condition is often whether the vitamin D function is working properly at the cellular level . The following summarizes the risks of vitamin D deficiency, the consequences of deficiency, and key factors affecting absorption and efficacy.

1 ) Controversy and background of high-dose vitamin D
Brazilian physician Dr. Cobra has long studied autoimmune diseases and proposed the " Cobra Protocol ":
- Dosage range : 60,000–200,000 IU Vitamin D3 daily
- Objective: To overcome vitamin D resistance and allow autoimmune diseases to enter a remission phase.
- The success rate is said to be over 90%.
However, high doses of vitamin D also carry risks , the most common being hypercalcemia , which can lead to kidney stones .
2 ) The dangers of "vitamin D overdose" vs. "vitamin D deficiency"
- Excessive intake : Hypercalcemia, kidney stones
- Disadvantages : More susceptible to autoimmune diseases
Related diseases include: multiple sclerosis ( MS ), Graves' disease, lupus , rheumatoid arthritis, type 1 diabetes, vitiligo , and Hashimoto's disease (autoimmune causes of hypothyroidism), which ranks high.
Studies show that vitamin D is closely related to the immune system and participates in the regulation of more than 2,500 genes .
The recommended dose for maintaining immune function is approximately 8,000–10,000 IU/ day .
3 ) Vitamin D resistance
Many people cannot get enough vitamin D from sun exposure or diet alone . Common reasons include:
- Genetic differences : Some gene mutations can make people more susceptible to autoimmune diseases and less able to utilize vitamin D.
- Nutritional deficiencies : Low levels of magnesium, zinc, and vitamin K2 can impair vitamin D absorption and function.
- Viral effects : Some viruses can downregulate vitamin D receptors, leading to a decrease in immunity.
4 ) The "sun exposure - immunity" adaptation in the Stone Age and the gap with modern times
In ancient times, humans were exposed to sunlight for extended periods, resulting in a much higher intake of Vitamin D than we have today.
At that time, the body may even "shut down some genes" to avoid the negative effects of excessive UV exposure.
However, in modern times, the amount of sunlight exposure has decreased significantly, but the gene regulatory mechanisms have not changed accordingly, resulting in the widespread vitamin D deficiency and resistance today .
5 ) Methods to reduce the side effects of high-dose vitamin D
If a higher dose of vitamin D is required , the risk of side effects can be reduced in the following ways:
- Replenish Magnesium, Vitamin K2 , Zinc
- Limit calcium intake , especially avoid excessive dairy products.
This can effectively reduce the risk of high blood calcium.
6 ) Why is it not enough to just look at blood tests?
The commonly tested "blood vitamin D " level can only reflect part of the situation.
The real key lies in:
- Can Vitamin D function at the cellular level?
- Does it exist? Impedance, receptor downregulation, or nutritional deficiency
Even if the test result is "normal", the actual functionality may still be insufficient.
7 ) Key Points Summary
- Vitamin D deficiency is highly associated with autoimmune diseases.
- Involved in over 2,500 genes , it is the core of immune regulation.
- Vitamin D resistance is affected by genes, nutrition, and viruses.
- High-dose vitamin D should be taken in conjunction with magnesium, potassium (K2) , zinc, and calcium intake should be restricted.
- Blood test results alone are insufficient to reflect the true condition.
✨ Conclusion:
The truth about vitamin D is far more complex than simply "supplementing or not supplementing".
The key is not about impressive numbers, but about how to ensure that Vitamin D truly works at the cellular level to protect immunity and health.
