Which unique micronutrient can the human body synthesize when exposed to sunlight?
Answer
Vitamin D
While most vitamins and minerals must be obtained entirely through diet because the body cannot manufacture them, Vitamin D stands out as a notable exception. The human body possesses the inherent capability to synthesize Vitamin D when specific wavelengths of sunlight interact with the skin. However, the efficiency of this natural production process is not universal; it is subject to external variables, including geographical location and individual factors such as skin color, which can influence how much Vitamin D is produced endogenously.
