The most common type of vitamin D is vitamin D3, which is present in food and dietary supplements as well as in the skin. Vitamin D2, which is prescribed, is vitamin D. In general, studies reveal that vitamin D3 is metabolised by our bodies more quickly than vitamin D2. Most people can produce all of the vitamin D they require if given enough time in the sun. To maintain a normal amount of vitamin D throughout the year, many women do not, however, receive enough sun exposure. It is also challenging to obtain enough vitamin D from your diet because few foods are naturally high in the vitamin. The level of vitamin D is also impacted by other factors. If you are overweight or have dark complexion, for example, you may be at risk. There is conflicting evidence about the relationship between vitamin D and both success and natural fertility. According to several research, having enough vitamin D levels increases the likelihood that in vitro fertilisation and the transfer of frozen donor egg embryos would be successful. That relationship has not been proven by other investigations. Although the evidence regarding vitamin D and fertility is inconclusive, it might be worthwhile to request testing from your primary care physician. According to numerous studies, women who have vitamin D blood levels of at least 30 ng/mL are more likely to become pregnant.2-5 In two investigations, it was discovered that Caucasian and non-Hispanic white women were disproportionately more likely to become pregnant through IVF if their vitamin D levels were normal.
