Women and vitamin D

We all need vitamin D to build and maintain strong, healthy bones throughout our lives, without it we can develop bone diseases like osteoporosis and osteomalacia.  Women, however, are at an ever higher risk of developing these diseases, because we have less bone mass than men and we lose bone density as we age and our estrogen levels naturally decrease.  These two factors make it especially important for women to maintain an adequate amount of vitamin D throughout their life, as well as eating foods high in calcium.

No bones about it

Vitamin D helps our bodies absorb calcium and phosphorus, so together these three nutrients work to maintain healthy bone mass.  A deficiency in vitamin D can lead to brittle, thin, misshaped bones, osteomalacia (a softening of bones), or osteoporosis (weakened bone structure), which can also contribute to weakened muscle mass.[1] Women are 4 times more likely to develop these bone diseases than men are, especially women over the age of 50, as menopause kicks in, and hormone levels decrease.[2]  Often times, bone disease is not even detected until after a fracture has occurred caused from the weakened and thinned out bones.  To help prevent this, women should aim to take in 600-800IU daily of vitamin D, however many studies have shown that taking 1,000 IU has even more beneficial and poses no harm[3].

Building a baby?

Vitamin D is very important during periods of rapid growth, such as pregnancy.  Vitamin D allows us to absorb calcium and phosphorous into our bones and teeth.  There is also a vitamin D receptor in almost every cell of our body.  When we think of how quickly a baby develops during gestation, vitamin D is an important nutrient during this time. It is best to check with your practitioner, and also review the amounts in your prenatal vitamins.

The best source of vitamin D is sunshine, however our sun time can be limited due to higher latitudes, the colder weather, and sunscreen.  So, it is important to make sure you are meeting your vitamin D needs through a healthy diet of salmon, tuna, eggs, mushrooms, and fortified dairy (for more ideas try these recipes).  But diet alone may still not be enough when it comes to vitamin D, so check out the Ddrops family of products and take a daily supplement.
