Surprising Findings
Higher vitamin D intake (4 IU/g) did not reduce fat mass or leptin, despite increasing lean mass.
Many assume vitamin D helps with fat loss or appetite control; this study shows it can boost muscle without touching fat or hunger hormones.
Practical Takeaways
Ensure adequate vitamin D intake during growth phases (e.g., adolescence, pregnancy, recovery) to potentially support lean tissue development.
