Why you need more vitamin D

You are almost certainly not getting enough vitamin D, according to the latest medical evidence.

Along with other health researchers in the field, I am concerned that most people have far too little vitamin D for their best health – especially in the winter.

Research shows that Vitamin D at an optimum level has many health benefits that include:

  • Reducing the risk of, and mortality from, certain cancers
  • Lowering the risk of dementia
  • Reducing asthma symptoms
  • Reducing the risk of bone fractures
  • Improving your immune defences
  • … and even increasing life span

The NHS now recommends that people at risk of deficiency should consider taking a daily supplement of vitamin D, particularly during autumn and winter.

However, a huge weight of evidence shows that just avoiding deficiency with ‘adequate’ levels of vitamin D is not enough. You need to reach optimum blood levels of vitamin D to obtain the major health benefits.

But what is an optimum level?

Unfortunately there is a lot of confusion of what constitutes ‘adequate’ and ‘optimum’ levels. The UK is in the unhappy position of having an official RDA (Recommended Daily Amount) that is half the latest Public Health England recommendation – and a third of the new US RDA levels! And far less again than the optimum level that experts recommend.

So I have prepared a short e-book on the optimum level of vitamin D you should aim for. You can download it as a pdf now.
