Everyone’s talking about Vitamin D and how important it is to health (and fighting off the winter blues). In fact, there’s an epidemic of Vitamin D deficiency among Americans — Scientific American states that nearly 75% of all American adults and teens are suffering from not enough Vitamin D.

But did you know that Vitamin D is also essential to fertility? It turns out it is, and you should discuss this with your infertility specialist. Here’s why.

What is Vitamin D?

Vitamin D is the essential vitamin that helps us process critical minerals like calcium and magnesium, which are essential for bone health. Vitamin D deficiency during childhood can result in rickets—a condition where the bones fail to harden as they develop. In adults, Vitamin D deficiency can cause impaired bone mineralization and osteomalacia (bone softening), as well as a variety of symptoms ranging from fatigue, slow healing, depression, back pain, and more.

Not all Vitamin D is equal, and in fact, the term Vitamin D actually refers to a group of fat-soluble chemical compounds called secosteroids that our bodies produce naturally, and can be found in some foods. But our most important source for Vitamin D comes from something we’re often in short supply of this time of year, the sun.

In other words, you need to get plenty of Vitamin D to be happy and healthy. In fact, early research has shown that lack of Vitamin D might even contribute to cardiac health and your risk of cancer, so it’s important to make sure you get enough.

What is the Link Between Vitamin D and Infertility?

Vitamin D is critical to your fertility, and is also integral to the production of sex hormones in the body. Women who have sufficient Vitamin D levels (above 30 ng/ML) are both more likely to become pregnant and to produce high-quality embryos, compared with women with lower Vitamin D levels.

There’s also evidence to suggest that Vitamin D supplementation can reduce the symptoms of PCOS (see studies below), and PCOS is a major cause of female infertility. PCOS often goes hand-in-hand with a metabolic condition called Insulin Resistance (often called “prediabetes”) in which the organs cannot properly utilize the insulin released after eating food, causing weight gain and impacting ovulation significantly. Vitamin D helps regulate your insulin levels to help you ovulate, which naturally increases your chances of getting pregnant.

Vitamin D is a Critical Nutrient in ConceEVE ™

It’s for these reasons we’ve added 5 mcg of Vitamin D to our ConceEVE. This means with ConceEVE, you get 29% of the USDA recommended daily allowance. If you combine this with a healthy diet and sufficient exposure to sunlight, Vitamin D supplementation may help increase the chances for conception, increase the chances for healthy embryos, and increase the chances for live births. It also may  help promote menstrual regularity and reduce the symptoms of PCOS.

If you’re struggling with infertility, consider adding ConceEVE ™ to your regimen. If your reproductive endocrinologist recommends Vitamin D supplementation, ConceEVE is your ideal source of vitamin D along with other clinically proven ingredients to increase your chances of a healthy conception! Good luck!

“In women undergoing in-vitro fertilization, a sufficient vitamin D level (≥ 30 ng/mL) should be obtained. Vitamin D supplementation might improve metabolic parameters in women with PCOS. A high vitamin D intake might be protective against endometriosis.”

“Likelihood for live birth was reduced by 44% for women if the 25OHD level was < 30 ng/mL. In women with PCOS, serum 25OHD was an independent predictor of measures of reproductive success after ovulation induction.”
