Vitamin D Deficiency
Conditions
Brief summary
Vitamin D is a commonly available essential prohormone humans need to regulate blood calcium and has recently emerged as potentially helpful in combating severe COVID-19. Despite its importance, some studies estimate as much as 40% of the US population is deficient in vitamin D. Most available vitamin D supplements have little absorption data and are nearly all softgels or capsules. This clinical trial is designed as a preliminary pharmacokinetics study to assess the absorbance of a nano liquid D3 supplement that can be taken as an oral spray once daily. Preliminary evidence suggests that this nano liquid D3 may be absorbed more readily than commercially available softgel dosage forms of D3. This randomized, double-blind, placebo-controlled trial will compare nano liquid D3 to commonly available D3 oral softgels and a placebo control group over the course of a thirty-one (31) day study period.
Interventions
DIETARY_SUPPLEMENTSoftgel Vitamin D3
5000IU vitamin D3 taken as single oral softgel once daily for 30 days
DIETARY_SUPPLEMENTNano Liquid Vitamin D3
5000IU vitamin D3 taken as liquid oral spray once daily for 30 days
DIAGNOSTIC_TEST25(OH)D Blood Serum Test
A sample of blood is drawn off and processed for 25(OH)D levels at baseline, after 15 days of supplementation, and after 30 days of supplementation
OTHERPlacebo Control
Liquid oral spray once daily for 30 days. Solution identical in smell, taste, color, and production process to Nano Liquid D3, but containing no Vitamin D3.
