Screening for Optimal Vitamin D When Supporting Fertility and Pregnancy

Vitamin D plays a critical role in reproductive health, and emerging research continues to highlight its importance in both fertility and pregnancy outcomes. For individuals trying to conceive, assessing vitamin D levels can be a valuable first step in a comprehensive, naturopathic approach to care.

​At Dalhousie Health & Wellness in Port Dalhousie, St. Catharines, naturopathic doctor Dr. Natalie Stradiotto focuses on fertility and reproductive health, helping patients optimize key biomarkers—including vitamin D—to support healthy conception and pregnancy.

Vitamin D and Fertility Outcomes

Vitamin D supplementation has been shown to positively influence fertility and pregnancy rates. Research indicates that optimizing vitamin D levels may improve outcomes, particularly when combined with fertility treatments.
For example, studies have demonstrated:
    •    Improved ovulation rates in individuals with PCOS when vitamin D is added to treatment protocols
    •    Higher vitamin D levels associated with increased live birth rates
    •    Lower vitamin D levels linked to reduced fertility success
In one study, each 2.5 nmol/L increase in vitamin D levels corresponded to a 2% increase in live birth rate. Individuals with vitamin D levels above 112 nmol/L experienced up to a fourfold increase in live birth rates compared to those with lower levels.
Conversely, vitamin D levels below 75 nmol/L were associated with a 44% reduction in live birth rates.

Vitamin D and Miscarriage Risk

The relationship between vitamin D and miscarriage risk is particularly significant.

Research shows:

• Individuals with vitamin D levels above 95 nmol/L had an 82% decreased risk of               miscarriage
  
• For every unit increase above 75 nmol/L, miscarriage risk decreased by approximately 1%

These findings suggest that maintaining optimal vitamin D levels may be an important factor in supporting early pregnancy and reducing complications.

A Naturopathic Approach to Fertility

Fertility is complex and influenced by many factors, including hormones, nutrition, stress, and overall health. Naturopathic medicine takes a comprehensive approach by assessing multiple aspects of your health—including vitamin D status—to help identify and address underlying imbalances.
Working with a naturopathic doctor can help ensure you are supporting your body with targeted, evidence-informed strategies tailored to your individual needs.

Start with a Prenatal Screen

If you are trying to conceive or looking for support on your fertility journey, starting with a prenatal screening can provide valuable insight into your health.
Testing vitamin D levels is a simple but powerful step toward optimizing fertility and supporting a healthy pregnancy.
