You may have heard that "vitamin D overdose can lead to poisoning," but did you know that the real danger might be "vitamin D deficiency" ? Dr. Eric Berg provides an in-depth analysis of the safety, absorption problems, and synergistic effects of a daily intake of 10,000 IU of vitamin D with other key nutrients.

Vitamin D : Every cell needs it
- Every cell in the human body has a vitamin D receptor.
- Vitamin D is involved in immune regulation, anti-inflammation, mood stabilization, and blood pressure control.
- Most people are in a state of "latent lack," which leads to:
- Autoimmune diseases
- arthritis
- Depression
- hypertension
- Increased risk of infection
Vitamin D toxicity vs. Vitamin K2 deficiency
- Vitamin D toxicity is extremely rare, and it usually requires long-term intake of more than 100,000 IU to occur.
- The symptoms of toxicity are very similar to those of vitamin K2 deficiency , for example:
- Calcium is deposited in soft tissues such as arteries, joints, kidneys, and lungs.
- Osteoporosis and increased risk of fractures
Solution: Supplement with vitamin K2 ( MK-7 type) to carry calcium back from the blood vessels to the bones and teeth.
The Myth of IU Units
- IU (International Unit) is not a measure of weight or volume, but rather a "functional standard".
- 10,000 IU of Vitamin D ≈ 0.25 mg, sounds like a lot, but it's actually quite little.
- The recommended intake ( 600 IU ) is only sufficient to prevent rickets and is insufficient to address common immune and metabolic problems in modern people.
Factors that hinder vitamin D absorption
- Darker skin tone → decreased ability to absorb ultraviolet rays
- Older age → Reduced synthesis ability
- Obesity, insulin resistance → Vitamin D is blocked by fat
- High stress and genetic defects hinder transformation and absorption.
- Geographical location and season → insufficient sunshine
- Poor liver or gallbladder function → inability to produce bile for the absorption of fat-soluble vitamins
- Intestinal inflammation → decreased absorption
Best detection method
- Blood Spot Test : Simple and convenient blood collection at home.
- It is recommended to test the concentration of 25(OH)D in the blood :
- Ideal values: 35–40 ng/mL or 90–100 nmol/L
Vitamin D' s immune function
- Support T helper cells in distinguishing between "self" and "non-self".
- Prevention of autoimmune diseases (such as lupus and rheumatoid arthritis)
- Regulate immune response to prevent over- or under-regulation.
- It helps with lung health ( COPD , asthma)
- High doses (such as 50,000 IU ) can be taken for a short period of time to combat influenza or the common cold.
The contradiction between sun exposure and skin cancer
- Despite people's fear of sun exposure, skin cancer continues to rise.
- Vitamin D has a protective effect against melanoma.
- Long-term sun protection may actually lead to vitamin D deficiency and increase the risk of cancer.
How to safely supplement vitamin D ?
- Combine with Vitamin K2 ( MK-7 ) : Prevents calcium misplacement
- Supplementing with magnesium and zinc helps activate and metabolize vitamin D.
- Drink more than 2.5 liters of water daily : to prevent kidney stones
- Regularly monitor blood concentration to avoid over- or under-concentration.
In conclusion: Instead of worrying about overdosing, first check if you are deficient in anything.
Hong Kong residents often work indoors for long periods, receive insufficient sunlight, and have refined diets, making vitamin D deficiency potentially more prevalent and dangerous than you might imagine . A daily intake of 10,000 IU of vitamin D , combined with K2 , magnesium, zinc, and adequate hydration, is safe and beneficial for most people .
Starting tonight, stop being afraid of the sun and start supplementing with Vitamin D to build a strong foundation for your immune system!
