Vitamin D is a fat soluble vitamin that our body stores. There are two types of D Vitamin:

Vitamin D2 – ergocalciferol

• Vitamin D3 – cholecalciferol

D2 is the food source. D3 is synthesized in the skin after exposure to the sun. For more detailed information on Vitamin D please click here (this will open a new window)

It is a known fact that supplementation of Vitamin D can effectively treat rickets. Rickets is seen mainly in children and is characterized by soft pliable bones and deformities such as bowlegs, muscle pain, enlarged skull, spinal curvature, enlargement of the liver and profuse sweating. Because of the increased use of sunscreen, rickets is now being found more and more in adults. Vitamin D needs to be supplemented with Calcium and Phosphorus.

Fanconi Syndrome

Physical Performance Enhancer

There has been no evidence to prove that Vitamin D increases muscle strength in those that are deficient.


This disorder is a softening of bone. What follows is fractures, weakness, weight loss, pain and anorexia. This is caused by a lack of calcium and phosphorus needed by the bones and may be caused by a lack of Vitamin D.


Vitamin D has been labelled a proven natural medicine in the prevention of bone loss in postmenopausal women. To decrease the further risk of fractures, supplementation needs to include calcium.


Vitamin D has not been proven to prevent Type 2 Diabetes.

High Cholesterol

Even though it has been shown that people with low Vitamin D levels are more likely to have high cholesterol, supplementation does not significantly reduce total cholesterol.

PMS Premenstural Syndrome

Vitamin D supplementation is not effective for preventing the development of PMS. I can however, tell you what does help PMS.

RA Rheumatoid Arthritis

If you have a high intake of Vitamin D then you may have a lower risk of developing rheumatoid arthritis. In a new study where the results were announced at EULAR 2010, the Annual Congress of the European League Against Rheumatism in Rome, Italy, the results consistently showed that RA sufferers were all low in Vitamin D. However, the study also showed that when those in the study were supplemented with 800-1000IU per day, their Vitamin D levels did not rise to a normal healthy level. More research is being done to asses the viability of increasing the daily dose.

Sources of Vitamin D

Your best and cheapest way to source Vitamin D is to stand out in the sunlight for 15 minutes a day. However, exposure can vary according to where you live. If you live in the northern hemisphere for example, Canda, then you may go for months during winter, without any sunlight. This is when you need to supplement.

Our body does store Vitamin D, so we have the ability to provide our body with enough D to last 49 days without sunlight. It is interesting to note that if you are dark skinned or tanned, then exposure to the sun needs to be longer because Vitamin D competes with the skin pigment melatonin. Conversely, a fair person may only need to be in the sun for about 15 minutes a day. For darker people, the time may be 30 minutes.
