We all know about Vitamin D – the “sunshine vitamin” which is so good for your bones and teeth.  And, what better way to get Vitamin D than from a glass of fortified milk!

Yessiree – I am all set.

But, I bet that you didn’t know that Vitamin D deficiency is becoming more prevalent in our society.  Estimates suggest that it affects over 40% of adults. And, women are more prone to Vitamin D insufficiency. Why? Partially because we have limited outdoor activities (or wear sunshine religiously). And, our diet is in dire need of improvement.

What are some of the symptoms of Vitamin D deficiency?

  1. Gum disease –  you may notice that you have more bleeding of the gums.
  2. Mood swings or feeling down-  Vitamin D is important in the production of serotonin which is a neurotransmitter that regulates mood, appetite and sleep.
  3. Sleepiness – as I mentioned Vitamin D is important in the production of serotonin. Low levels of serotonin are associated with sleepiness.  Also, serotonin is converted to melatonin – and low levels of melatonin can also impact your sleep cycle.

  1. High Blood Pressure – although the exact mechanism is not well understood. There is evidence that people with high blood pressure have lower levels of Vitamin D.
  2. Muscular and bone weakness – we’ve all heard about how Vitamin D is essential for strong bones, but it is also implicated on muscle weakness as well.

There are many other symptoms – so it worth getting your tested when you go see your physician.

What are some ways to increase your intake of Vitamin D? 

  • Well, obviously you can take Vitamin D3 capsules (generally no more than 4,000 IU / day – unless advised to increase it by your physician). Vitamin D3 is the active form of the nutrient / hormone. The best way to take this is with a meal as it is fat soluble.
  • So, why doesn’t fortified milk work? Well, almost all milk in the US is fortified with 400 IU of Vitamin D (per quart) – which mean to get the necessary amount of Vitamin D – you would have to drink 10 quarts of milk!

I like milk – but, not that much!

  • Eat more fatty fish like salmon (360 IU/3.5 ounce serving). Again, you would need to eat quite a few servings.
  • I think the best way is to get 15- 30 minutes of sun exposure about 3 times a week. If you are fair skinned – it is estimated that, with the midday summer sun, your body can produce about 10,000 IU in just 10 minutes. If you have darker skin – it takes longer.  And, because it is fat soluble – your body stores it for future use as well.


So, check with your doctor if you have any of these symptoms. If you go the supplementation route – it is important to know how much of the vitamin you will need.
