Vitamin D Scientific Studies
Vitamin D is currently being studied for its roll in helping prevent many of our most serious and challenging illnesses.  For information about the most recent scientific studies please visit

In addition to being vital for a fully functional immune system, vitamin D is well documented for increasing absorption of calcium and phosphorus from the small intestine.  This helps explain why children who do not get enough vitamin D in their diets are at increased risk of developing rickets resulting in poor bone and tooth quality. Adults with low levels of vitamin D are more likely to develop osteomalacia (similar to rickets) or osteoporosis which is the loss of bone density.

Insufficient Vitamin D may contribute to insomnia, nervous system deregulation, type 1 and 2 diabetes, bone and muscle pain and many degenerative diseases.

Vitamin D from the Sun
Sunlight is the best source of vitamin D, as it will never lead to vitamin D toxicity.  One should expose as much skin as possible to the sun, without risking sunburn.  Sunscreens however will stop you from producing vitamin D.  95% of vitamin D production is eliminated with a cream of sun proof factor (SPF) 8. It is also important to know that it takes about half an hour for the vitamin to be absorbed into the blood stream.  So do not shower for at least 30 minutes after sun exposure.

For maximum benefit, only expose yourself to the sun long enough to turn the skin the palest shade of pink.  There is no additional benefit after this point, and you will only be contributing to oxidative stress and skin ageing.

Who Needs Vitamin D Supplementation?
It is estimated that 80% of people in Northern Europe and America are vitamin D deficient.  The low angle of the sun, combined with the amount of time now spent inside, make it almost impossible for people to produce sufficient of this vitamin with its vital, hormone-like properties. Because there are relatively few foods that contain vitamin D to support us, especially through winter, it may be wise to rely on a vitamin supplement to meet your daily needs.

Vitamin D reserves are stored principally in the liver, where they halve, roughly every two months, even without use.  It is therefore now postulated that colds and flu, together with SAD (seasonal affective disorder) strike during the winter months simply because these reserves have depleted and our immunity, brain and nervous functions begin to suffer.

Vitamin D Supplementation Dosage
Currently Vitamin D blood concentrations of 50 to 60 milimoles per liter are thought to be optimum, although there is discussion as to whether this should be revised to 80 - 100 millimoles.  Toxicity is only thought to be reached at levels well over 200 mm/l.

According to the Journal of Nutrition March 2009; 139(3):540-6  supplementation dosages during the autumn and winter months are:

Vitamin D Dose Recommendations
Age Dosage
Below 5 35 units per pound per day
Age 5 - 10 2500 units
Age 18 - 30 5000 units
Pregnant Women 5000 units

There is no way to know if the above recommendations are correct. The ONLY way to know is to test your blood. You might need 4-5 times the amount recommended above. Ideally your blood level of 25 OH D should be 60ng/ml

Recent discussions and appreciation of the importance of Vitamin D have lead to increases in the recommended daily allowance, which now stands at 1000 iu per day for adults

It is advised that you do not take over 1000 IU of vitamin D daily without doctor supervision.  Too much vitamin D may cause nausea, weakness, constipation, irregular heartbeat, weight loss, seizures, and irritability.

Doses of 1,800 IU units a day can cause stunted growth in infants and young children. Too much vitamin D can lead to birth defects, coma, or even death.
