Study Arms (2)

Intervention: solubilized vitamin D3 in MCT

EXPERIMENTAL

The intervention dose and duration aims to correct their vitamin D deficiency to sufficient status (total serum 25(OH)D \>/=30 ng/mL or 75 nmol/L). According to an oral cholecalciferol (D3) loading dose guideline for vitamin D-deficient adults (van Groningen et al. 2010), cumulative dose of more than 200,000 IU solubilized vitamin D3 would be applied in current RCT, with make sure the sufficient supplement. Intervention group will receive 144,000 IU in week0 (W0) and then every 2 weeks of 72,000 IU for total 8 weeks (totally 5 times: 144,000 IU wk0/ 72,000 IU wk2/ 72,000 IU wk4/ 72,000 IU wk6/ 72,000 IU wk8), theoretically to achieve sufficient levels of vitamin D.

Dietary Supplement: solubilized vitamin D3

Placebo: MCT with same amount

PLACEBO COMPARATOR

control group will receive same volume amount of medium chain triglyceride (MCT).
