Vitamin D3 - 5000 IU

Article: 11253

Health Benefits:
Vitamin D3 is widely recognised for its roll in bone health, and positive influence on heart and arterial health, immune system function, maintenance of healthy glucose levels, and cognitive function.

Recent research suggests that Vitamin D3 dosages of 5,000 - 10,000 iu for adults according to body weight may provide significant health benefits including immune support during the darker months.

Although these levels are far higher than the current, recently raised recommended daily allowance, even these levels fall well below the level of over 20,000 iu your body will produce daily when exposed to the summer sun.

Vitamin D3's hormone- like action make is a most powerful nutrient for improving overall health. It controls phosphorus, calcium, and bone metabolism as well as neuro-muscular function.

Principally manufactured by sunlight, Vitamin D3 deficiency has reached pandemic proportions due to our indoor lifestyles. It is suggested in the medical literature that the current recommended daily intake is insufficient to protect against many of the diseases it is known to have a protective effect against at higher dosages of at least 2,000 iu daily.

Zinc and Iron are often found to be poorly regulated or even deficient in Vitamin D deficiency. Vitamin D enhances the activities of Vitamin A, and Zinc reduces the toxicity of Vitamin A, while Iron reduces the toxicity of Zinc. These four are seen as part of the pathology of Alzheimer's, Parkinson's and some peripheral neuropathies including Restless legs syndrome.

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 aging.

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 millimoles 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

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 may lead to serious health conditions.  It is highly recommended that you monitor your blood vitamin D levels.
