Saira Salmon Nutritionist talks about us losing Vitamin D

We’re Losing our Vitamin D……

For the next 6 months!  We’re almost at the autumn equinox, and the sun is falling lower and lower in the sky.  Not only is winter on its way, but living where we do in the Northern hemisphere our body has all but lost its ability to convert sunlight to Vitamin D.  For the next 6 months we are going to have to live off what we have stored up over the summer months…..and studies clearly show that most of us are well and truly deficient even in the summer months.

Why does this matter?  Because almost every single cell has a Vitamin D receptor, and needs Vitamin D to thrive.  The more we learn about it the more we understand that not only does it help us keep our skeleton and teeth strong, but good levels help prevent numerous degenerative diseases taking hold – things like depression, Parkinsons, sleep disorders, heart disease, autoimmune disorders, arthritis, birth defect, asthma, immune function and even Chron’s disease.  It has also been shown to be of benefit in over 17 different types of cancers, and sports people find a deficiency impairs their performance.

So as you can see, its important.  Indeed, some scientists are getting so excited about the potential health benefits of Vitamin D that there are calls for widespread Vitamin D supplementation to brought in.  For example, Robert Heaney, Professor of Medicine at Creighton University, Omaha called for an ‘immediate improvement in Vitamin D status of the general population’. [1] Given the list above, it is quite dizzying to think of the potential benefits that might be reaped by the general population from just supplementing adequate amounts of Vitamin D.   Lack of vitamin D has not been a major problem for most of the human race for much of our evolution, as we spent most of our time outdoors –those who didn’t got rickets.  Now with cosy houses, televisions, computers, office jobs and cars the majority don’t often get outside even when the weather is good.

So, taking a Vitamin D supplement daily is something of a no-brainer for us poor sun-starved Brits.  The next question is how much should you take?

Well, experts calculate that minimum levels for health should be AT LEAST 10 times the government-set RDA, which most experts agree is wholly inadequate.  In fact, many of the leading Vitamin D researchers such as Dr John Cannell, Dr Michael F Holick, and Reinhold Veith all believe daily intake of 5,000 IU is needed and perfectly safe.  And I have to say, they’ve got me convinced because this is where I aim for most of the year.  We may see Government guidelines updated but it usually takes years for them to catch up with research.  That’s a long time to wait to get the best ‘official’ advice if you are ill, so always do your own research and that way you’ll be ahead of the curve.

Don’t forget the older you are the more you need, and also dark skinned people are likely to be even more deficient than light skinned.

It’s too important to leave to chance or just hope that you have sufficient sun exposure during the summer to see you through the winter.  I use a sublingual spray which delivers a whopping 3,000 IU per spray.  Very easy and safe to use.  If you’re interested contact for more info.
