Vitamin D isn’t called the “sunshine vitamin” for nothing — symptoms of deficiency can include unexplained fatigue, loss of focus, sleep disorders, weakness and even depression. But don’t worry if you haven’t been taking your multivitamins religiously — you can get plenty of vitamin D from food and even exposure to the sun. Here are a few ways to beat vitamin D deficiency:
  • Sunlight/Sun Lamps
A little light spurs the body to make vitamin D, but use caution: only about 20 or 25 minutes in the sunlight is helpful. Be mindful of prolonged sun exposure and make sure to use sunscreen if you’ll be out for any longer.
  • Foods
Fatty fish like mackerel, salmon, tuna and eel are all rich in vitamin D, along with mushrooms, fortified milks, orange juice and cereals, and egg yolks.
  • Supplements
Vitamin D3 supplements along with cod liver oil can help increase vitamin D levels. But note that vitamin D3 supplements aren’t vegetarian and some part of the production might occur outside the United States. One more point: supplements are not regulated by the FDA.
