Weekly calcifediol may help maintain vitamin D levels in deficient women

According to NutraIngredients, a new study in Nutrients found that weekly calcifediol (vitamin D3) supplementation can raise and maintain vitamin D levels in women with a deficiency over 12 months.

The authors say the regimen may be useful for both premenopausal and postmenopausal women across different BMI groups. They describe it as a practical approach to correcting the deficiency.

The findings rest on a single source. The announcement does not provide details of the sample, dosage or methodology, so the results should be read within the scope of the described study.
