2016 study: The relationship of serum vitamin D and Zinc

Post by jimmylegs » 1 year ago

glad to have seen this, finally. now i need the chicken/egg clarification.. i get the zinc finger connection where 1,25(OH)2vitamin d3 levels are concerned, but i'm still curious re zinc interactions with plain old 25(OH)vitamin d3.

The relationship of serum vitamin D and Zinc in a nationally representative sample of Iranian children and adolescents: The CASPIAN-III study (2016)

Background: Vitamin D (VitD) deficiency is a common worldwide problem. Some previous studies have shown that both Zinc (Zn) and VitD deficiency are prevalent in Iran. This study aimed to assess the relationship of serum Zn and vitamin D levels in a nationally representative sample of Iranian children and adolescents.

Methods: This case-control study was conducted as a sub-study of a school-based surveillance program entitled "the CASPIAN-III Study". An equal number of individuals with and without hypovitaminosis D including 330 participants aged 10 to 18 years were selected. The correlation of serum 25 hydroxy vitamin D (25(OH) D), cardiometabolic factors and Zn concentrations was determined. Statistical analysis was done using one-way analysis of variance (ANOVA), Pearson's correlation, linear regression, and logistic regression.

Results: The mean age was not significantly different in participants with and without hypovitaminosis D (14.74±2.52 vs. 14.74±2.66 years, respectively, p>0.05). The mean 25(OH) D level was 6.34±1.47ng/ml in the group with hypovitaminosis D and 39.27±6.42ng/ml in controls. The mean Zn level was significantly lower in the hypovitaminosis D group than in controls (1.15±0.26 vs. 1.43±0.32μg/ml, respectively, p<0.001). The Pearson's analysis showed a positive and significant correlation between Zn and 25(OH) D serum levels (p<0.0001). Odds ratios analysis for VitD level between various quartiles of serum zinc concentration for all participants showed that the odds of higher levels of VitD increased by higher levels of Zn.

Conclusion: We found significant associations between low serum concentrations of zinc and 25(OH) D. Food fortification or mineral supplementation should be considered in future health programs.


"Finally, conducting future studies to identify the factors affecting Vitamin D and Zinc deficiency in schoolchildren, their relationship and the real causes of simultaneous lack of VitD and Zinc is highly recommended."

yes pls. i still want to know for certain whether correcting my zn deficiency played a causative role in my tripled dose response to d3 supplementation. the timing is right but the lit i've found to date suggests greater impact resulting from the work i've done on magnesium status.
take control of your own health
pursue optimal self care at least as actively as a diagnosis
ask for referrals to preventive health care specialists eg dietitians
don't let suboptimal self care muddy any underlying diagnostic picture!
