Life Extension Vitamin D3 3000iu 120 Softgels

For you, if you are looking for an optimal dose of immune health-supporting vitamin D3

The active ingredients in Vitamin D3 can:

  • Support bone density
  • Contribute to the immune system and bone health
  • Support cell differentiation and blood pressure regulation


Don’t accept deficiency of Vitamin D during the winter months. Vitamin D in Vitamin D3 can help you maintain normal vitamin D levels.

With Vitamin D3, 3000 IU you can get the multitude of health benefits that vitamin D is known for providing, from supporting bone density to contributing to the immune system. Vitamin D3 is produced in the skin from exposure to sunlight, but sunscreens and low light conditions in the winter make that difficult. These factors emphasize the importance of taking vitamin D supplements, all year round.

Why it Works:

Vitamin D3 can be produced by your skin if you are being exposed to sunlight continuously. During winter time your body’s ability to produce enough vitamin D may be hindered, which can lead to Vitamin D deficiency, and in turn emphasise the need for taking vitamin D supplements on a regular basis [1-33]. Vitamin D has long been associated with support for healthy bone density [1-33]. Vitamin D has also been proven to play a role in regulating healthy cell proliferation as well as supporting the immune system and playing a role in maintaining a healthy mental wellbeing. Moreover, research findings have also linked deficiency of vitamin D to many common age-related problems [1-33].

Life Extension recommends that you supplement with 5,000 IU to 8,000 IU of vitamin D3 every day. Take a 25-hydroxy vitamin D blood test after 3 months to assess and adjust your dosage.  The optimal blood levels will be between 50–80 ng/mL year-round.

The Science Behind the Product:

Studies reported that insufficient intake of vitamin D is associated with higher risk of diseases that span all systems in the body [34]. Even if we are able to make some amount of vitamin D in our bodies, we often still need extra amounts of vitamin D in order to function normally. This additional amount of vitamin D can come from our diet, sun or supplements [34].

Additionally, when vitamin D is ingested in the diet or produced in the skin, liver and kidneys convert vitamin D to its active form known as 1,25-dihydroxyvitamin D [34]. Vitamin D is needed for you because vitamin D is responsible for regulation of genes that control cell growth and development, immune function and metabolic control [34].

It was reported in the studies that people who are deficient in vitamin D  can have an increased risk to develop numerous of chronic disorders [34]. These disorders are type II diabetes, infections and cardiovascular, autoimmune and neurological diseases [34].
