Vitamin D and K for military healthcare workers
Part of Hormones & metabolism clinical trials.
This study tests whether taking vitamin D3 and K2 supplements can improve health in military healthcare workers who have low vitamin D levels. If you qualify, you will stop any current vitamin D or K supplements and take the study supplement for 4.5 months.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Your vitamin D level must be 30 ng/mL or lower (confirmed by a blood test within the past few months).
- You must be willing to stop taking any vitamin D or K supplements for the 4.5-month study period.
- You need to be a military beneficiary (active duty, retired, or a dependent of one).
