Most of us are aware of vitamin D being essential for maintenance of teeth and bone health, and it does this by supporting the incorporation of calcium, and reducing the loss of calcium from the teeth and bone structure. However, lack of vitamin D has been related to anxiety and depression. This makes sense, seeing as we tend to have the winter blues through the darker months with less sun. So in this blog, we undcover the relation to vitmain D and anxiety.
For the typical well known benefits, the RDA level of 5µg per day is normally adequate. Recently however, there have been enormous levels of publicity surrounding major scientific studies performed over the last 30 years which strongly indicate that higher levels of vitamin D are potentially very beneficial in a wide range of other health issues. In particular, vitamin D appears to assist our cells in regulating their function so that they remain normal.
On 21st July 2016, the UK government published recommendations based on a review by the Scientific Advisory Committee on Nutrition (SACN) stating that everybody in the UK should supplement 10mcg (micrograms) of vitamin D every day throughout the Autumn and Winter months. This is equivalent to 400iu. In addition, the government stated that people who do not spend substantial time outdoors (for example, old or institutionalised people) and those who wear clothes that cover most of their skin whilst they are outdoors, should supplement vitamin D daily all year round. The recommendations have been applied to babies 0-3 and children aged 4-11 as well as older children and adults - 10mcg or 400iu is the recommended dose for all of these age groups.
We usually measure the strength of Vitamin D using micrograms and IU's. A microgram is the measurement by weight of a nutrient. It is usually abbreviated as mcg or ug, these are the same thing. The IU is an International Unit, usually used to measure fat soluble vitamins including Vitamin A, D and E.
