Vitamin D deficiency is a key factor in immune imbalance.
Many Hong Kong people believe that vitamin D is only related to bone health, but Dr. Eric Berg points out that the most common and severe nutritional deficiency in patients with autoimmune diseases is vitamin D3 .
He cited the Coimbra Protocol , developed by Brazilian physicians , pointing out that high-dose vitamin D therapy can help many patients with immune imbalances recover their health. However, the key is not just "how much" to eat, but whether the body can truly absorb and utilize vitamin D.

Why are your vitamin D supplements ineffective? The key lies in "vitamin D resistance".
Many people have normal vitamin D levels but still experience immune problems, which may be known as " vitamin D resistance " —meaning that you take vitamin D but it cannot effectively enter cells and exert its effects .
Dr. Berg points out that by simultaneously testing the levels of parathyroid hormone ( PTH ) and vitamin D , it can be determined whether the body is truly absorbing the nutrients. If vitamin D is high but PTH is still high, it indicates that the body has developed resistance.
The causes of resistance include:
- ** Genetic polymorphism (gene defect) ** leads to abnormal vitamin D receptor function;
- Insufficient sunlight (especially for those with darker skin, older age, high stress, or those who spend long periods indoors);
- Chronic infections and pathogens (such as Lyme disease) can reduce vitamin D receptor expression by up to 60 times ;
- Heavy metals, environmental toxins , and chronic inflammation can also inhibit receptor function.
In other words, many people are not actually not eating enough, but rather not having enough to eat.
How can we ensure that vitamin D is truly effective?
To overcome vitamin D resistance, Dr. Berger suggests:
- Supplement with sufficient D3 and monitor PTH levels to decrease to the lower normal range.
- Combined with vitamin K2 (it is recommended to use 100 µg K2 for every 10,000 IU D3 ), it helps calcium to properly enter the bones and prevents calcification of arteries and joints .
- Supplementing with magnesium and zinc , these two minerals help vitamin D convert into its active form.
- Avoid contamination, processed foods , and exposure to heavy metals to reduce receptor damage.
- Get plenty of sunshine ( ideally before 10 am or after 4 pm ) to allow your skin to naturally synthesize vitamin D.

Stop focusing solely on numbers and truly care about "absorption capacity".
In Hong Kong's urban environment, characterized by insufficient sunlight and a stressful lifestyle, vitamin D deficiency is actually quite common. Many office workers may find that vitamin D is ineffective even when they take supplements daily due to bodily resistance or malabsorption .
If we can simultaneously monitor changes in parathyroid hormone levels and supplement with essential nutrients such as K2 and magnesium, vitamin D can truly exert its immune-regulating and anti-inflammatory effects, building long-term protection for the body.
