Many Thais Are Deficient in Vitamin D

Most people assume that living in a tropical country like Thailand means there’s no need to take extra Vitamin D—just getting sunlight should be enough. However, data from Bumrungrad International Hospital reveals a different story.

Studies show that residents in Bangkok have significantly lower Vitamin D levels compared to those in other regions. Over 60% of Bangkok residents and nearly 50% of people in urban areas across Thailand suffer from Vitamin D deficiency, at a higher rate than those living in rural areas.

Why Sunlight Alone Isn’t Enough

Although the body can synthesize Vitamin D from sunlight, modern lifestyles have changed how we spend our time:

• Staying indoors with air-conditioning for long hours

• Avoiding direct sunlight

• Reduced sunlight exposure during the winter season

• Post-COVID lifestyle shifts, with fewer outdoor group activities

All of these factors reduce the chances of getting sufficient Vitamin D naturally from the sun.

The Benefits of Vitamin D for the Immune System

One of the key roles of Vitamin D is to support the immune system.

Research published in Frontiers in Nutrition found that Vitamin D helps activate white blood cells, which play a vital role in eliminating harmful pathogens that enter the body. This makes Vitamin D a crucial nutrient for maintaining strong immunity.

Vitamin D Works Better with Vitamin C and Zinc

The same research also highlighted that Vitamin D works synergistically with Vitamin C and Zinc. Together, they help strengthen the proteins that connect and protect cells, reducing the chance of pathogens invading the body.

In contrast, a deficiency in these nutrients may weaken cell linings, leaving the body more vulnerable to infections.

How to Boost Your Vitamin D Intake

Vitamin D can be found in foods such as salmon, tuna, and shiitake mushrooms. However, the amount from food alone is often insufficient to meet the body’s daily needs.

That’s why many people turn to Vitamin D supplements or fortified beverages. One convenient option is “Hi!
