Official title
Vitamin D Absorbance Study - A Decentralized, Randomized, Double-blind, Placebo-controlled Clinical Trial of the Pharmacokinetics of Vitamin D3 Absorption From Softgel Supplements Compared to Nano Liquid D3 Supplements in Humans.
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
