Vitamin D3 5,000IU

Maintaining healthy levels of vitamin D can help mitigate cognitive decline. Plus, clinical trials confirm the importance of maintaining vitamin D levels for broad-spectrum health benefits, such as bone and immune system health. If you are already getting 1,000–3,000 IU of vitamin D in your multivitamin, Vitamin D3 5,000 IU is perfect for achieving optimal vitamin D levels.

Benefits at a Glance

  • Vitamin D helps regulate the body’s calcium balance
  • Supports healthy cell differentiation and immune health 
  • Promotes healthy blood pressure already within normal range 
  • Supports healthy bone density
  • Perfect complement to multivitamins with 1,000 IU to 3,000 IU vitamin D 
  • Size: 5,000 IU - 60 softgels


Vitamin D is fat-soluble, and effects the expression of more than 200 genes in your body.1 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 preventing 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.3 Vitamin D affects cell differentiation, immunity, insulin secretion, blood pressure regulation, etc.4-33

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!
