Vitamin D3 supplementation in women practicing orthodox religious and intermittent fasting: A controlled study with formulation-specific effects
A daily regimen of oral vitamin D3, administered as either drops or tablets, is effective in significantly improving vitamin D status and reducing PTH concentrations in women adhering to intermittent fasting religious practices. These findings support targeted supplementation strategies in at-risk fasting populations, particularly those with vitamin D deficiency, regardless of the form of oral supplementation.
