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 .
Effect of vitamin D supplementation on anthropometric indices among overweight and obese women: A double blind randomized controlled clinical trial.
AIMS The aim of this study was to investigate effect of vitamin D supplementation on anthropometric indices among women with overweight and obesity . METHODS This double blind r and omize clinical trial was conducted on 66 overweight and obese women . Those in intervention group received oral supplement of vitamin D 50,000 IU ( 1250 mcg ) per 25 day and in control group participants received placebo for 3 months . Anthropometric indices were measured before and after 3 months intervention . Before the intervention a 24-h dietary recall ( 3 days ) were used to assess dietary intake of individuals . Independent t test and multivariate repeated measure were used to data analysis . RESULTS The mean difference of anthropometric indices , serum calcium , 25 ( OH ) D3 and serum PTH between the intervention and control groups were significant ( P < 0/05 ) . However , no significant differences in serum phosphorus between the intervention and control groups were seen . CONCLUSION Supplementation with vitamin D 50 μg for each day for 3 months result ed in a significant reduction in anthropometric indices in women with obesity and overweight with normal primary 25(OH ) D3 serum levels
