Introduction

Vitamin D deficiency is widespread, even in developed countries. Certain populations are more vulnerable due to lifestyle, biology, or environment. Understanding who is most at risk can help target prevention strategies.

High-Risk Groups

Introduction

Beyond bone strength, vitamin D plays a key role in regulating the immune system. In recent years, interest has grown in how vitamin D status affects susceptibility to infections and chronic diseases.

Vitamin D and Immune Function

Introduction

Sunlight is the most natural and efficient source of vitamin D. However, balancing safe sun exposure with protection against skin damage is critical. Excessive exposure increases the risk of skin cancer, while inadequate exposure can lead to vitamin D deficiency. Here are evidence-based guidelines to help maintain optimal vitamin D levels safely.

Understanding Vitamin D

Vitamin D, often referred to as the “sunshine vitamin,” is a fat-soluble nutrient that plays a critical role in human health. Unlike many vitamins, the body can synthesize vitamin D endogenously when the skin is exposed to ultraviolet B (UVB) radiation from sunlight. Despite this unique ability, vitamin D deficiency is common worldwide and is associated with a wide range of health concerns.
