About this trial
This is an interventional basic science trial for Vitamin D Deficiency focused on measuring Vitamin D3, Vitamin D deficiency, estradiol, omega-3 fatty acids, menopausal
Eligibility Criteria
Inclusion Criteria:
- Premenopausal females
- Medical diagnosis of vitamin D deficiency (VD < 30 ng / ml)
Exclusion Criteria:
- Women previously diagnosed with any chronic disease such as kidney diseases were excluded from the study due to the effect of prolonged administration of VD3 on kidney stones formation. Women who are pregnant, breastfeeding or using hormonal contraceptives were also excluded.

5. Study Description
Brief Summary
The effect of vitamin D3 and omega-3 Fatty acids on estradiol levels.
Detailed Description
The data about effect of vitamin D3 (VD3) and omega-3 fatty acids (omega-3FA) on serum levels of estradiol (E2) are scarce and conflicting and nothing is published in the literature about the effect of the combination of VD3 and omega-3FA on the E2 levels.
This study was conducted to investigate effect of VD3 and omega-3FA alone and with each other on serum E2 levels in premenopausal females with vitamin D deficiency (VDD).
This randomized, placebo-controlled clinical trial was designed to test effects of 50,000 IU VD3 weekly and 300 mg omega-3FA daily for eight weeks, separately and with each other, on the mid-follicular serum levels of E2 and 25-hydroxy vitamin D (25OHD). This study was conducted during winter in 86 healthy premenopausal Jordanian females with VDD with a mean age of (32.8 ± 8.9) years. Fasting serum levels for 25OHD, E2, PTH (parathyroid hormon), calcium, phosphate, ALT (alanine aminotransferase), and urea were assessed at baseline and the end of the trial.
