Puritan'S Pride VitaminD3 1000IU , X100 Softgels

VitaminD is a fat-soluble vitamin that can be obtained through the diet or synthesized in the skin upon exposure to sunlight. VitaminD3, the form of vitaminD formed in the skin, is a potent and active form of the vitamin. VitaminD2 is a vitaminD analog formed in plants, mushrooms and yeasts during photosynthesis. While vitaminD2 is sometimes used in food fortification, Puritan’s Pride supplements provide the active form.

VitaminD plays a regulatory role in the growth, differentiation, and proliferation of different types of white blood cells.8** It is important to regulate these processes to maintain immune balance. Think of a thermostat set to 70degrees.

When the temperature falls below 70degrees the heat comes on but once the temperature is reached, the heat needs to turn off or else the temperature will continue to rise indefinitely. The same delicate balance is needed for our immune systems to maintain optimal health.

The T and B cells of the adaptive immune system are both regulated by vitaminD.** Many cells of the innate immune response also require vitaminD such as monocytes which need it to mature properly.** Adequate concentrations of vitaminD are also necessary for the synthesis of important proteins with immune-fighting properties
