New research has shown a clear correlation to low Vitamin D levels and miscarriages (referred to below as recurrent spontaneous abortions or RSA.)
Previous studies had shown that there might be an association between serum vitamin D concentrations and the occurrence of recurrent spontaneous abortion (RSA). However, the conclusions remained controversial. The objective of this study was to systematically review the evidence for an epidemiological association between vitamin D and RSA. The literature search was performed in the following databases: PubMed, Web of Science, Embase and Chinese databases.
Conclusion: Patients with RSA had lower serum vitamin D levels than normal pregnant women, and pregnant women with VDD might be at higher risk for RSA.
I recommend a high-quality vitamin D+K, which work synergistically for better absorption. Click HERE or on the image to be taken to the Your Fertile Health store.
The dose one may need of Vitamin D is dependent upon your current levels. Please reach out to me if you would like to get a lab draw; the cash price of which is $36. This requires that you take the lab requisition slip I provide in .pdf form to bring with you to Labcorp (must be Labcorp, which acts as phlebotomy station for Professional Co-Op, the lab testing company). If you would like to know your Vitamin D levels, schedule an appointment with me HERE.
Which trimester is vitamin D most important?
Because calcium demands increase in the third trimester of pregnancy, vitamin D status becomes crucial for maternal health, fetal skeletal growth, and optimal maternal and fetal outcomes.
Can too much vitamin D hurt a fetus?
When taking vitamin D during pregnancy, be aware that excessive supplementation can occur with vitamin D, leading to toxicity. Hypercalcemia refers to a buildup of calcium in the blood and can happen to the fetus when too much vitamin D is ingested. The highest daily dose evaluated in pregnancy is 4,000 IU/day.
