Sponsor's own description

This randomized controlled trial (RCT) will compare the change in vitamin D status (25-hydroxyvitamin D nmol/L) after a 4 week intervention with 4 groups: 1. Vitamin D enriched (20ug) olive oil emulsion drink 2. Vitamin D enriched (20ug) coconut oil emulsion drink 3. Placebo emulsion drink 4. Vitamin D supplement (20ug) Participants will be randomized to 1 of 4 intervention group. Hypothesis 1: 25-hydroxyvitamin D concentrations are higher in the olive oil emulsion drink group compared to the placebo emulsion drink group post intervention. Hypothesis 2: 25-hydroxyvitamin D concentrations are higher in the olive oil emulsion drink group compared to the coconut oil emulsion drink group post intervention.
