Understanding Vitamin D's Role and Sources
Vitamin D is often categorized differently from traditional vitamins because the body can synthesize it from sunlight, although many individuals do not obtain sufficient sunlight exposure. Sources of natural vitamin D include fatty fish like salmon and tuna, with significant amounts also found in UV-exposed mushrooms and fortified products like plant-based milks. For example, three ounces of salmon provide about 570 international units of vitamin D. Due to varying exposure and dietary sources, relying on supplements may be necessary to achieve adequate levels.
