To test the efficacy of different vitamin D delivery methods on serum 25(OH)D. Participants randomly assigned to one of seven groups - three placebo groups and 4 active supplement groups receiving 100,000IU vitamin D3
Various delivery methods of vitamin D supplementation are available to consumers but there have been no studies providing evidence of whether one delivery method is superior to others. The researchers wanted to compare the delivery of 100,000IU vitamin D3 by three methods on serum 25(OH)D levels. Two methods of oral supplementation (pill [prolonged release] and liquid [immediate release]), and delivery through the skin (with and without a penetrator enhancer. Placebo groups were pill, oral liquid and skin applied oil

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
