Vitamin D is fat-soluble, and effects the expression of more than 200 genes in your body. It is essential for optimal health, and yet there is a widespread vitamin D deficiency. You can bring blood vitamin D to optimal levels2 through repeated sun exposure.
But sunscreens and low light in winter make that difficult, and the American Academy of Dermatology has reaffirmed that vitamin D should not be obtained from unprotected exposure to ultraviolet (UV) radiation from the sun or indoor tanning devices. Therefore, supplementing with the right amount of vitamin D goes a long way towards inhibiting vitamin D deficiency.
Vitamin D has multiple health benefits
Once vitamin D3 is produced in the skin or absorbed from food, it’s converted in the body to a metabolically active form known as calcitriol that does far more than just regulate your body’s calcium balance. Vitamin D affects cell differentiation, immunity, insulin secretion, blood pressure regulation, etc.
Perfect complement to multivitamins with vitamin D
We recommend that you supplement with 5,000 IU to 8,000 IU of vitamin D3 daily. And take a 25-hydroxy vitamin D blood test after 3 months to assess and adjust your dosage so your optimal blood levels will be between 50–80 ng/mL year-round. So maintain optimal levels of blood vitamin D effectively and inexpensively with Life Extension® vitamin D supplements!
