Sunscreen and Vitamin D: Separating Fact from Fiction

Living in a tropical country like Indonesia often means plenty of sunshine. But despite this abundance, many people still experience vitamin D deficiency. This can be due to avoiding sun exposure and using sunscreen. A common concern is whether sunscreen hinders vitamin D production. While it's true that sunscreen does block some UV rays, it's important to understand how this affects vitamin D levels.

Sunscreen and Vitamin D Production

Contrary to popular belief, regular sunscreen use doesn't significantly impact your vitamin D levels. Numerous studies have shown that sunscreen application has little to no effect on vitamin D concentration. While the US Food and Drug Administration (FDA) states that sunscreen can block vitamin D absorption when used excessively (more than an ounce), most people don't apply that much sunscreen.

Important Reminders

While getting vitamin D from sunlight is essential, too much exposure to ultraviolet (UV) rays can increase your risk of skin cancer.

UV exposure is linked to 80-90% of skin cancers.

Consistent sunscreen use is crucial for reducing your risk of skin cancer.

Alternative Ways to Get Vitamin D

Sunlight Exposure:

5-30 minutes of sun exposure per day, without sunscreen, is enough to produce vitamin D.

The best time to sunbathe is between 10 am and 4 pm, at least twice a week.

* Expose your face, arms, hands, and feet to the sun.

Food: Salmon, tuna, eggs, and mushrooms are some foods rich in vitamin D.

Supplements: Consider taking vitamin D supplements if you don't get enough from other sources.

Maintaining Vitamin D Levels

It's crucial to consult your doctor to determine the right vitamin D intake for you. A healthy balance of sun exposure, a nutritious diet, and, if necessary, supplements can help ensure you maintain optimal vitamin D levels for good health.
