Dietary Sources: While limited, certain foods contain vitamin D, including fatty fish (salmon, tuna, mackerel), egg yolks, and fortified milk and dairy products.
Supplements: Vitamin D supplements can be beneficial for individuals with limited sun exposure or those with dietary supplements restrictions. However, it's essential to consult your doctor before starting any supplements.
