7 Compelling Reasons to Supplement with Vitamin D, especially during Winter

Vitamin D is widely recognised as a key pro-hormone for optimal function of many body systems.

The Vitamin D sensitive conditions are:
1. Cardio Vascular Disease
2. Respiratory Infection
3. Respiratory Disease
4. Cancer
5. TB
6. Diabetes Mellitus

The supplementation:
7. Low cost and very low adverse reaction

The Dosage:

Research suggests that doubling the recommended Vitamin D levels from 55nmol/l (the level of Vitamin D in your blood) to 110nmol/l would have a significant reduction in all causes of mortality!

In Australia the recommended level is only 25nmol/l (so we could all do with a boost!)

Take daily - preferably combined with Vitamin C and Zinc - for maximum impact on winter immunity.

This article suggests that the optimal level is 100nmol/ml:

Other research suggests that levels over 60nmol/ml will offer the most benefits.

It is regarded as very hard to reach Vitamin D toxicity. A single dose of midday sun can have the skin produce from 10,000 to 25,000 IU of Vitamin D. (IU = International Units, the amount of Vitamin D in whichever supplement you are taking, usually available as 1000 IU per tablet/spray).

This article will allay your concerns about toxicity and dose levels:

The recommended daily dose is in the 4000 – 10,000 IU depending on your health status and the time of the year. In winter, if you have a healthy system disease that we know benefits from higher Vitamin D levels or you have a respiratory infection, the upper level of intake is recommended. So, if you're taking a tablet or spray of 1,000 IU, then between 4-10 doses per day.

Interesting data about Vitamin D:
Vitamin D is produced by the body from sun exposure in the middle of the day. The enzyme Enos will sulphate Vitamin D so that sulphur can be transported in the blood to the organs and tissues that need it. When the sun is at a low angle particularly above and below the 35th parallel the sun intensity is too low to trigger the production of Vitamin D. Leura in the Blue Mountains is on 33.7 degrees latitude which is just above the latitude that will severely reduce our natural Vitamin D production, so at high risk.

You may have heard that the majority of the COVID deaths have been in nursing homes world wide. There are a number of factors that all feed together, however, over 90% of nursing home residents have Vitamin D levels that are very low. This, in tandem with the data that shows that a percentage of nursing home residents were sent there from hospital when they are not well enough to go home again. This group of residents live between 6 and 12 months after they are discharged from hospital to a nursing home.

If we look at the data, it is evident that the populations above and below the latitude of 35 degrees have much lower Vitamin D in the winter months. For this reason it is highly recommended that we supplement with Vitamin D during Autumn and Winter.
