Vitamin D: Not Just for “Bones”

It is a common misconception to think, "Thailand is so sunny, how could anyone possibly lack Vitamin D?" However, the shocking reality is that over 45% of the Thai population suffers from "Vitamin D Deficiency."

Vitamin D is not merely a nutrient that helps absorb calcium for your bones. In modern medicine, it is classified as a "Hormone-like substance." It plays a critical role in the immune system, brain function, and cardiovascular health in ways you might not expect.

Beyond Strong Bones: The Powerful Benefits of Vitamin D

While its primary duty is calcium absorption to prevent osteoporosis and osteopenia, Vitamin D offers immense benefits to other body systems:

1. Boosts the Immune System: It stimulates white blood cells to fight pathogens and helps prevent allergies and autoimmune diseases (such as SLE).

2. Restores Mental Health: It helps reduce stress, fights depression, and improves sleep quality.

3. Controls Chronic Diseases: It aids in regulating blood sugar levels and blood pressure, thereby reducing the risk of cardiovascular disease.

4. Reduces Pain: It helps alleviate pain associated with rheumatoid arthritis.

5. Balances Hormones: It supports the normal functioning of the hormone synthesis system.

Check Now: Are You at Risk of Deficiency?

Even though the body can synthesize Vitamin D from sunlight (UVB) by 80-90%, modern lifestyles often prevent us from getting enough. You are at risk if you:

• Work in an office or stay indoors all day.

• Apply sunscreen regularly (which is necessary for skin protection, but blocks Vitamin D absorption).

• Live in a city where dust and pollution block sunlight.

Groups that should have their Vitamin D levels tested via blood work:

• The elderly (skin synthesis capability decreases with age).

• Working-age women who rarely get sun exposure.

• Individuals prone to infections.

How-to: Properly Replenish Vitamin D

Our bodies receive Vitamin D from two main sources: Sunlight (80-90%) and Food (10-20%).

1. Food Sources

Since we cannot fully rely on sunlight in today's environment, choosing the right food is essential. Focus on:

• Fatty fish: Salmon, Tuna.

• Cod liver oil.

• Egg yolks, mushrooms, grains, certain algae, milk, and dairy products.

2. Daily Requirement

The appropriate amount of Vitamin D depends on age and condition. Here is the recommended daily intake:

• Infants (less than 1 year): 400 IU (10 mcg) per day.

• General Public (1 - 70 years): 600 IU (15 mcg) per day.

• The Elderly (70 years and older): 800 IU (20 mcg) per day.

• Women planning pregnancy: 400 - 600 IU (10 mcg) per day.
