With Vitamin D3 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. However, applying sunscreens and fewer hours of daylight in winter means that it’s difficult for the body to produce all the Vitamin D that it needs. These factors emphasize the importance of taking vitamin D supplements, all year round.
Vitamin D3 can be produced by your skin if you are being exposed to sunlight continuously. Because winter offers fever hours of daylight, your body will produce less vitamin D in winter than in summer.
This can lead to a vitamin D deficiency and emphasises the need for taking vitamin D supplements regularly [1-33].
Vitamin D is a highly important vitamin for a variety of reasons. It has long been associated with supporting bone density [1-33] and has also been proven to play a role in regulating healthy cell proliferation as well as supporting the immune system.
Furthermore, it has also been shown to play a role in maintaining healthy cognitive function.
Life Extension® recommends that you supplement with vitamin D3 every day. Take a 25-hydroxy vitamin D blood test after three months to assess and adjust your dosage. The optimal blood levels are between 50–80 ng/mL year-round.
Studies reported that insufficient intake of vitamin D is associated with a higher risk of health problems that span all systems in the body . Even if we can make some amount of vitamin D in our bodies, we can benefit from extra amounts of vitamin D to maintain optimal blood levels.
This additional amount of vitamin D can come from our diet, or supplements .
Additionally, when vitamin D is ingested in the diet or produced in the skin, the liver and kidneys convert vitamin D to its active form known as 1,25-dihydroxyvitamin D .
Vitamin D is needed for you because vitamin D is essential for healthy bones, and promotes cardiovascular, immune and cognitive health. It´s also responsible for the regulation of genes that control cell growth and development 34].
Take one (1) softgel once daily with food. Individuals consuming more than 2,000 IU/day of vitamin D (from diet and supplements) should periodically obtain a serum 25-hydroxy vitamin D measurement. Do not exceed 10,000 IU per day unless recommended by your doctor. Vitamin D supplementation is not recommended for individuals with high blood calcium levels.
