Vitamin D Supplements May Help Women Conceive, New Study Claims

vitamin D and fertility

An association between Vitamin D and fertility and conception rates has been identified in a new study. Women undergoing fertility treatment were shown to have an increased chance of success when their Vitamin D levels were adequate, compared to those who were lacking in the Vitamin.

Now, researchers are asking for a randomised clinical trial to be carried out, in order to investigate Vitamin D’s role in boosting live birth rates.

Understanding the results of the study

The review and meta-analysis carried out at the Birmingham University, delved into the live birth success rate of women who had undergone Assisted Reproduction Treatment (ART). The results, published within the Human Reproduction journal, revealed those with adequate Vitamin D levels, were one third more likely to deliver a healthy, live baby.

Data for 2,700 women undergoing fertility treatment such as IVF, was analysed during the study. It was discovered that a staggering three out of four women who were trying to conceive, had insufficient Vitamin D levels. Just 26% were deemed to have sufficient Vitamin D.

The link was discovered via blood tests. The researchers were keen to stress that they hadn’t looked into the effectiveness of using Vitamin D supplements to increase fertility. However, the discovery does support the fact that many women find it easier to conceive during the summer months.

Vitamin D supplements are also recommended by medical experts during pregnancy. So, it does now seem the vitamin is proven to have beneficial effects both for conception and for a healthy pregnancy.

What is the relationship between Vitamin D and fertility?

At present, little is known as to why Vitamin D plays a role in increased fertility and live birth rates. There is a theory that it could boost embryo implantation success, or it could simply be an insight into the overall health of the woman which helps.

There has also been a study carried out on mice which revealed those with insufficient levels of Vitamin D had trouble forming normal, healthy, mature eggs. They also showed to have an underdeveloped uterus.

Women should be wary of rushing out for Vitamin D supplements

Although a clear link has been revealed, experts are warning women not to rush out and stock up on Vitamin D supplements. Further research needs to be carried out to determine whether supplements could be a safe, effective way to boost fertility.

The trouble is, it is possible to overdose on Vitamin D and this could cause numerous health issues. In particular, an excess level of the vitamin could cause excessive calcium build-up, which in turn can damage the kidney’s and heart, as well as cause the bones to weaken.

So, while the new research does seem to suggest Vitamin D supplements could prove useful in boosting fertility in women, clinical trials will need to be carried out. In the meantime, those experiencing difficulties conceiving have numerous fertility treatment options available. Book a consultation today to see which treatments could prove most effective for you.
