Could some of your infertility stress/depression be related to vitamin D deficiency? Quite possibly according to a 2011 study (1) on more than 81,000 women. The study showed that those with the highest intake of vitamin D from their diet had a significantly fewer symptoms of depression. The researchers concluded:

"Our results support an inverse association of vitamin D intake from foods and the occurrence of depressive symptoms in older women."

Prior studies have shown that vitamin D deficiency is prevalent in infertile women, and that vitamin D deficiency may reduce the likelihood that IVF will succeed. Vitamin D it seems may have a powerful effect upon your fertility and your brain, helping neurotransmitters such as dopamine and norepinephrine function in a more balanced way (1):

"Vitamin D may affect the function of dopamine and norepinephrine, which are monoamine neurotransmitters that are likely involved in depression. Furthermore, vitamin D may modulate the relation between depression and inflammation."

Optimizing your vitamin D levels could be a great way to buffer yourself against infertility stress while upping your chances of conceiving. Vitamin D is known to reduce inflammation in the body too and this may be another mechanism whereby vitamin D helps infertility; some forms of infertility especially endometriosis have been linked to excess inflammation.

Vitamin D also seems to reduce many forms of auto-immune diseases and an over-aggressive immune system has been implicated in various forms of infertility, implantation failure and recurrent loss. The immune calming effect of vitamin D could be yet another key way that the sunshine vitamin may help speed conception.

If you are suffering from infertility - and depression - you may find benefit physically mentally and emotionally from spending more time in the sun - without sunscreen - and asking your physician about taking a vitamin D3 supplement daily. In the wintertime the noontime sun is most likely to up your vitamin D levels naturally.

A connection between vitamin D and depression has been discovered before; in 2006 a study evaluated the vitamin D levels of eighty people and assessed their mental health. It was discovered that those with the lowest levels of vitamin D were eleven times more likely to be depressed than those with higher vitamin D levels.

Although the current RDA for vitamin D is a scant 600 IU per day some studies suggest that many adults may need almost ten times this amount of vitamin D3 daily to get their vitamin D levels in the middle of the reference range. The reference range - for the 25 OHD test - in current use is 30 - 100 ng/ml and it is thought to be ideal to raise your vitamin D levels to the mid-range, ideally between 50-70 ng/ml.

As vitamin D is a fat-soluble vitamin it is best taken with a fat-containing meal to maximize absorption and vitamin D3 is thought to be the best form of the vitamin to supplement with. A prescription vitamin D is also available which many physicians prescribe when levels fall too low. Be sure to ask your physician for a vitamin D test and for further monitoring to check your progress if you choose to supplement.
