Vitamin D3



Vitamin D3 5000 IU - Get a Little Sunshine for Your Gut

When it comes to gut health, not many vitamins are more important than Vitamin D3. Vitamin D is responsible for regulating various functions in the gut that help with lowering inflammation, among other effects of leaky-gut1.

Another aspect of vitamin D is it’s immune boosting capabilities. Among its many tricks, vitamin D is able to increase autoimmune function2—your body’s ability to self-regulate balanced health. Autoimmune conditions like Diabetes are usually the first things to flare-up when the gut is compromised.

Taking Vitamin D3 - 5000 IU is perfect for boosting your levels, adding support to a multivitamin, and providing an overall increase in your well-being that was affected due to vitamin D deficiencies.3  




Vitamin D3 - 5000 IU

Maintaining healthy levels of vitamin D can help mitigate gut 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


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 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.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!
