Recent research on vitamin D

How to obtain vitamin D

Sunlight is the easiest way to obtain vitamin D, but it is hard to estimate how much time you should spend in the sun as it’s dependent on your skin type. For example, those of African and Asian heritage may need to spend longer in the sunshine to obtain enough vitamin D. It’s also important to take care not to burn.

Some research on this matter has been done in Spain. Researchers from the University of Valencia  analysed ultraviolet solar irradiance - or the time it takes for the skin to redden - in Valencia. Rays were monitored for one month of each season between 2003-2010.

The results show that the average person (skin type III) should not spend more than 29 daily minutes in the city's direct sun during July.

In January, the same individual can remain exposed for 150 minutes to get enough of the nutrient. 

Vitamin D is also found in fatty fish, like tuna, mackerel, and salmon, beef liver, cheese and egg yolks.

Should we supplement vitamin D?

The latest advice from Public Health England is that adults and children over the age of one should consider taking a daily supplement containing 10mcg of vitamin D, particularly during autumn and winter.

People who have a higher risk of vitamin D deficiency are being advised to take a supplement all year round.

So what's the latest thinking on vitamin D?

The CPD Nutrition MATTERS aims to bring medical professionals up to speed with the latest information on this valuable vitamin and will feature case studies on Vitamin D deficiency and Osteoporosis and well as management of nutrition medicine and conditions

Other speakers include Professor Sam Lingam and Dr Philip Hawes and there will be opportunity for a question and answer session for the experts.
