Sun exposure is the most natural way to get vitamin D. However, the amount of vitamin D produced from sun exposure varies depending on several factors, such as the time of day, latitude, skin pigmentation, and the use of sunscreen.
Vitamin D supplements are available in various forms, including capsules, tablets, and drops. They are particularly beneficial for individuals who do not get enough vitamin D from sun exposure or diet.
Certain foods are naturally rich in vitamin D, such as fatty fish (salmon, tuna, mackerel), egg yolks, and fortified foods like milk, cereals, and orange juice.

Vitamin D has anti-inflammatory properties and may help reduce chronic inflammation, which is linked to various health problems, such as heart disease, diabetes, and arthritis.
Melanin, the pigment that gives skin its color, also blocks ultraviolet (UV) rays from the sun, which are necessary for vitamin D production.
Certain conditions, such as Crohn's disease, celiac disease, and obesity, can interfere with vitamin D absorption.
Individuals who spend little time outdoors or live in areas with less sunlight are at higher risk.
As we age, the skin's ability to produce vitamin D from sunlight decreases.
Vitamin D deficiency can be diagnosed with a simple blood test. If you are found to be deficient in vitamin D, your doctor may recommend one or more of the following treatment options:
