Life Extension - Vitamin D3 (3000 IU)

Quick Overview

Vitamin D3 is a fat-soluble vitamin that is responsible for your body's absorption of calcium and phosphorus. Having optimal Vitamin D3, calcium and phosphorus levels is important for building and maintaining healthy, strong and dense bones in humans. Vitamin D is used to prevent and treat certain bone disorders as well. In the Northern and Western part of the world, Vitamin D3 deficiencies are becoming more and more prevalent, hence why it is a great idea to supplement with it. You can stack your multivitamin supplement with Life Extension's "Vitamin D3" (3,000 IU) to obtain the optimal Vitamin D3 levels in your blood.

The Broad-Spectrum Health Benefits Of Vitamin D3

Maintaining healthy levels of Vitamin D within in the body can help mitigate cognitive decline, meaning that it can support the normal function of the brain even as we age. Many clinical studies also confirm that maintaining healthy vitamin D levels is important to experience broad-spectrum health benefits, i.e. bone density and immune system health. If you are already taking in 1,000–3,000 IU of vitamin D from your multivitamin supplement, Life Extension's "Vitamin D3" (5,000 IU) is the perfect choice for achieving optimal vitamin D levels.

Key Benefits Of Vitamin D:

  • It helps regulate the body’s calcium balance
  • It supports healthy cell differentiation and immune system function 
  • It promotes healthy blood pressure levels in individuals who are already within the normal range 
  • It supports healthy bone density
  • It is a perfect complement to multivitamins containing 1,000 IU to 3,000 IU vitamin D 

Vitamin D is fat-soluble and affects the expression of over as much as 200 genes within your body. It is completely essential for optimal health, and yet there is a widespread vitamin D deficiency that seems to occur more and more these days. You can bring the vitamin D in your blood to optimal levels through repeated exposure to sunlight. Sunscreens and darker times with less daylight in winter make that difficult to do. The general recommendation is that you should not try to obtain your Vitamin D through exposure to UV-rays via unnatural sunlight, like you would in a tanning bed for example.  This is exactly why supplementing with the right amount of vitamin D goes a long way towards fighting vitamin D deficiency, and Life Extension's "Vitamin D3" (5,000 IU) is perfect for that.

Vitamin D offers multiple health benefits.

When vitamin D3 is produced in the skin or absorbed from food, it gets converted to a metabolically active form in the body. This form is known as calcitriol and it does much more than simply regulate your body’s calcium balance. Vitamin D affects cell differentiation, immune system function, insulin secretion, blood pressure regulation, etc. All benefits that are crucial to your health and well-being.

Stack your multivitamin supplement with "Vitamin D3" (5,000 IU).
