    What Is Vitamin D3 Good for?

    Vitamin D3 is a chemical synthesised in skin when we are exposed to ultraviolet light, and has a wide range of beneficial health properties. Without adequate levels of vitamin D3, we are more at risk of mineral deficiencies, bone deformities, poor immune function and depression.

    Mineral Metabolism

    Adequate vitamin D3 levels are required by the body for the proper absorption and utilisation of minerals such as calcium and phosphorous, which are important for the health of bones. Low levels of vitamin D3 may cause an increased risk of bone disease such as osteoporosis and rickets.

    Immune Activity

    Cells of the immune system, such as macrophages, which hunt the body for dangerous pathogens such as viruses, bacteria and cancer cells, have receptor sites for vitamin D3. As such, vitamin D3 may play a role in stimulating these cells to be more active in their hunt for disease-causing microbes.

    Mood Balance

    Vitamin D3 is required to maintain the balance and function of the parathyroid gland, which secretes hormones that, in very high levels, may cause depression. Low vitamin D3 levels may cause depression in some individuals.
