Vitamin D-deficient diet led to decreased serum concentration of 25(OH)D3 in mice and increased body weight. The mice were given a diet that contained vitamin D (VD+) or lacked vitamin D (VD-) and were treated five days/week for two weeks with propylene glycol control, or with 100 μg/kg ß-caryophyllene (BCP) by oral gavage. a) Plasma 25(OH)D3 concentrations after treatment. Control groups: *p < 0.01; BCP groups: *p < 0.05. 25(OH)D3, 25-hydroxy vitamin D3, was used as a marker for vitamin D. b) Body weight after treatment. Control groups: *p < 0.05; BCP groups: *p < 0.01.
