difference between vitamin d & sunlight

Vitamin D, often called the "sunshine vitamin," can be obtained from both sunlight exposure and dietary supplements. Sunlight triggers vitamin D production in the skin, supporting bone health, immune function, and mood regulation. However, factors such as geographic location, skin tone, sunscreen use, and lifestyle can limit natural vitamin D synthesis, making supplements an essential option for many people.

This article explores the benefits of sunlight versus vitamin D supplements, including absorption rates, health effects, and safety considerations. Understanding the balance between the two can help optimize your immune system, hormone regulation, and long-term wellness.
