How Does Vitamin D3 work?
Vitamin D3, also known as cholecalciferol, is a form ofvitamin D thatthe body manufactures when skin is exposed to UV radiation from thesun. It's converted from food sources and sunlight into its activeform, calcitriol, by the liver and kidneys.
Vitamin D is necessary for the maintenance of healthy calcium andphosphorous levels in the body. Calcium, the main structural element inbones and teeth, can only be absorbed by the body when vitamin D ispresent. Vitamin D is therefore essential for building and maintaininghealthy bones and teeth. It's also believed to contribute to increasedmuscle strength, which may help improve balance a

Vitamin D also plays a part in regulating cellular growth and keepingthe nervous and immune system functioning properly. A review article inthe September 2006 issue of Progress Biophysics Molecular Biology
It's estimated that a significant percentage of adults suffer fromvitamin D deficiency. Vitamin D deficiency is associated with a varietyof health complications, including rickets (in which bones are unableto properly calcify, or harden) in children, poor prostate health inmen and poor bone health in older adults.
The elderly, alcoholics and strict vegetarians (vegans) areparticularly at risk for deficiency and should consider regularsupplementation. Individuals with darker skin pigments may also be atincreased risk, as darker skin contains higher levels of melanin, whichmay inhibit the skin's ability to produce vitamin D from sunlight.Also, people with intestinal malabsorption, hyperthyroidism, liver orkidney disease, or pancreatic conditions may be at risk.
Vitamin D deficiencies are common among those with overactiveparathyroid glands. This gland is responsible for maintaining calciumlevels, which is vital for proper functioning of the muscular andnervous systems. One study found that insufficient levels of immunecells were produced in the thymus glands of laboratory animals withvitamin D deficiencies. However, a normal eight-week vitamin D intakeled to healthy levels.
Recent studies suggest that the current RDA/DV of vitamin D (200 IU forindividuals under age 50,400 IU for those between the ages of 50 and70, and 600 IU for those over the age of 70) may not be adequate. Infact, optimal levels are between 2,000 and 4,000 IU per day.indicated that vitamin D can also helpmaintain healthy blood pressure,blood sugar and overall cellular health¹
