A study by Cambridge University found that an average 1 in 10 men and women aged 40 to 80 were vitamin D deficient – probably because they were spending too much time indoors.
Spending a lot of time indoors during the summer months can contribute to deficient levels. Think about your lifestyle. Do you spend all day in an office? Do you travel by car? Do you use suncream of factor 15 or above when out in the sun? Do you socialise indoors? All of these factors prevent us naturally producing vitamin D from the sun.
As we head into winter though, we can’t even get the vitamin D we need from the sun, it simply isn’t strong enough in the northern hemisphere. The easiest way to top up your levels during the darker, colder months is supplementation. It is only possible to get 10% of what you need from your diet, for example you would have to drink 80 glasses of milk a day!
So how much should you take?
The NHS measures vitamin D in nanomoles per litre (nmol/L). You should aim for levels between 75nmol/L and 150nmol/L, this level is understood to be optimal for improved health.
As a guideline maintenance dosage we recommend taking 1000IU of vitamin D for every 25kg of body weight. For an adult living in the UK this normally equates to one spray of D3000 vitamin D oral spray daily.
If your levels are below optimal then you may need a higher dose initially to boost your vitamin D.
Wondering how you know?
Living in the UK you will most likely need to work on increasing your levels of the sunshine vitamin. You can confidently take D3000 daily to help boost your levels, however you may want to use our simple home testing service to find out exactly what you need.
