Overall , intervention groups obtained higher 25(OH)D concentration than controls and there was obvious dose – response effect between intake dose and 25(OH)D concentration .
Baseline 25(OH)D concentration and age were significant indicators for 25(OH)D concentration .
Conclusions Regional- and age-specific recommended dosages of VitD supplements for population to achieve optimal 25(OH)D concentrations have been suggested
Background / Objectives Optimal doses of vitamin D ( VitD ) supplement in different population s are unclear .
We aim to evaluate the relationship between VitD supplementation and post-intervention serum 25-hydroxyvitamin D [ 25(OH)D ] concentration , to provide a recommended dosage of VitD for achieving an optimal 25(OH)D concentration for different population s .
Effects of Vitamin D and Exercise on the Wellbeing of Older Community-Dwelling Women: A Randomized Controlled Trial
Background : Evidence for the effects of exercise and vitamin D supplementation on quality of life ( QoL ) , fear of falling ( FoF ) and mental wellbeing in older adults is conflicting . Objective : To study the effects of vitamin D supplementation and multimodal group exercise on psychosocial functions of wellbeing , including QoL , mental wellbeing and FoF. Method : This is a 2-year , double-blind , placebo-controlled vitamin D and open exercise intervention trial with 409 older Finnish women ( 70 - 80 years of age ) r and omized to 4 treatment arms : ( 1 ) placebo without exercise , ( 2 ) vitamin D ( 800 IU/day ) without exercise , ( 3 ) placebo and exercise , and ( 4 ) vitamin D ( 800 IU/day ) with exercise . Exercisers participated in group exercise twice per week for 12 months and once per week for the subsequent 12 months , plus home exercises . Results : When comparing with the placebo without exercise group , there were no statistically significant differences between groups receiving either vitamin D , exercise or both treatments for changes in QoL or mental wellbeing ( although a slight decline was seen in mental wellbeing in those receiving vitamin D only , p = 0.044 ) . The initial slight reduction in FoF was significant in all intervention groups compared with controls ( p < 0.05 ) , but this was only temporary . Conclusion : Neither vitamin D nor exercise contributes to better QoL , FoF or mental wellbeing in community-dwelling healthy older women with sufficient vitamin D levels
