Along with supporting the immune system, brittle bones, bone pain, healthy cell division, and other age related issues, Life Extension Liquid Vitamin D3 may also provide support for low birth weight, daytime sleepiness, and certain types of cancer.

Vitamin D3 can be synthesized by humans in the skin upon exposure to ultraviolet-B (UVB) radiation from sunlight. But, due to the winter season, weather conditions, and sun block, the body’s ability to produce optimal vitamin D levels may be inhibited.70 In fact, it has been proposed that annual fluctuations in vitamin D levels explain the seasonality of influenza.71 All of these factors point to the value of taking a daily vitamin D supplement.

Vitamin D has long provided significant support for healthy bone density.72-77 However, scientists have also validated the critical role that vitamin D plays in regulating healthy cell division and differentiation, and its profound effects on human immunity.78-81 These findings link a deficiency of vitamin D to a host of common age-related problems.

The current RDA is only 600 IU. As a result of startling evidence of a widespread vitamin D deficiency, prominent nutritional scientists are calling on Americans to increase their vitamin D intake to 1,000 IU per day and higher. Currently, most experts in the field believe that intakes of between 1,000 and 10,000 IU for adults will lead to serum 25(OH)D levels above those indicative of vitamin D deficient levels, at approximately 80 nmol/L or 32 ng/mL.

Life Extension recommends that healthy adults supplement each day with at least 2,000 IU of vitaminD. Elderly adults may benefit from higher doses such as 5,000 IU daily up to 10,000 IU daily. The objective of taking a vitamin D supplement is to achieve an optimal 25-hydroxy vitamin D blood level of 50 ng/mL (and higher). Life Extension’s analysis of over 13,000 vitamin D blood tests reveals that the minimum intake for most aging people should be around 7,000 IU a day. Some individuals (such as those weighing over 180 pounds) may require higher potencies of vitamin D.

Even if we follow a good diet, it may be difficult to get enough vitamin D. Supplements may be required.1 Certain groups of people are more prone to low levels. They include:2

  • Older adults skin has a more difficult time making vitamin D from sunlight and their kidneys can't convert vitamin D to its active form very well.
  • Dark skinned people have skin that does not produce vitamin D from the sun easily.
  • Certain disorders such as Chron's disease, celiac disease, or others that have a difficult time with fat being absorbed as vitamin D requires it.
  • Overweight people have body fat that binds to the vitamin D instead of it getting into the blood.

Vitamin D helps the body to absorb calcium which is essential for bone formation. Vitamin D deficiency can cause rickets in children.1,2 Rickets is where bones become soft and bend.2 In adults, deficiency can lead to osteoporosis1 (fragile bones likely to break3) and osteomalacia2 (bone pain and weak muscles2).

Aside from bone disorders, studies suggest vitamin D may help protect against certain types of cancer such as colon, prostate, and breast cancers.2 Researches have also found that low levels of vitamin D in pregnant women may lead to a low birth weight which may cause concerns such as premature death of the baby or the developing of various chronic conditions such as heart disease, type 2 diabetes, and high blood pressure as they get older.4 Low levels of vitamin D have also been linked to daytime sleepiness. The study was done on people who were diagnosed with sleep apnea. Lower levels of vitamin D were associated with higher levels of daytime sleepiness.5
