Boost vitamin D levels at home this winter

Taking supplements is one way to ensure you're getting enough vitamin D during the colder months

One of the more unenjoyable elements of modern life is that we spend so much time cooped up in offices. While we know this can wreak havoc on your posture (and probably doesn't do much for your mental wellbeing either), you might have a bigger issue to worry about - vitamin D deficiency.

In the year 2011-12 the Australian Bureau of Statistics found one in four Australian adults are deficient in vitamin D, which is essential for keeping teeth and bones healthy, regulating mood and improving resistance against winter bugs.

The best source of this vital vitamin is getting out in the sunshine; when the sun's UVB rays hit our skin, a reaction takes place that enables the cells to manufacture it.

The problem is, all those hours squirrelling away at your keyboard mean many of us rarely see daylight during the colder months. Booking a two-week holiday to the Bahamas would be ideal, but in reality, few of us have the time or money to jet off so close to Christmas.

Regardless, now winter's almost here, it means fewer sunny days, so you need to be extra-vigilant about getting enough of the good stuff. Here's how to combat bleaker days and up your vitamin D intake during the chill.


Next time you're stuck for ideas for a quick and healthy dinner, head to the fish aisle. Salmon, mackerel, herring, trout and kippers are all brilliant sources of vitamin D that many of us don't eat often enough. In fact, just half a fillet of salmon has over 1,000 IU of vitamin D, which is more than the daily recommended allowance for a person (according to government advice, we should all be aiming for 1000 IU in the winter months). Fresh fatty fish also supplies iron, zinc, niacin, vitamin B6 and vitamin B12, in addition to a whole host of other nutrients you need for good health.


Got milk? Then get swigging. According to research, an 200ml glass of whole milk contains at least 100 IU of vitamin D, a quarter of your daily optimum vitamin D intake. Not all milk products contain this essential vitamin, so make sure you're looking out for fortified varieties.


Dippy eggs and soldiers are more than just homely comfort food - they're also great for, you guessed it, vitamin D. All the goodness in an egg comes from its yolk, so it's important to use the whole egg and not just the whites. One egg will give you about 40 IU, which is a brilliant excuse to get stuck into this teatime treat.


In a similar way to humans, certain varieties of mushrooms can produce vitamin D when exposed to sunlight. Research has uncovered that shiitake 'shrooms are the best at mimicking the process. There are thought to be 40 IU in 120 grams of the potent fungi, which might not sound like a huge amount, but when it comes to staying healthy - every little bit helps.


Let's face it, we're all busy people, and one of the easiest ways to win at winter health is to simply take a supplement. Just don't snack on them like Fruit Pastilles; taking high doses of the vitamin for long periods of time can lead to excessive build up in the body, so keep a close eye on your numbers.
