- Reasons for low response to vitamin D
Examples for migrants getting injections include: low Magnesium, Smoking, Cola drinks, Genes, poor health, liver problems - Response to a large dose of vitamin D (80,000 IU) typically varied by 2 X – June 2016
Note: some had poor responses, but none had negative responses
- 78 percent of pregnant immigrants in Sweden had less than 10 ng low vitamin D – Nov 2013
- Immigrants and refugees had lower vitamin D levels – Jan 2013
- Immigrant vitamin D deficiency in Europe – May 2011
- Overview Vitamin D Dose-Response includes many graphs, such as the following
Note that virtually all had a good response fo a large dose - Vitamin D injection lasts longer and has bigger response than weekly oral – Jan 2017

In a cross-sectional screening programme, we assessed serum vitamin D levels in adult Eritrean refugees recently arrived in Switzerland. Median vitamin D level among 107 participants (95 males and 12 females) was 27 nmol/l (interquartile range 23–42 nmol/l), 86% had insufficient vitamin D levels (≤50 nmol/l) and 36% severe deficiency (<25 nmol/l). In 29 participants who received single-dose intramuscular vitamin D substitution (300 000 IU), median vitamin D levels increased from 25 to 35 nmol/l after 3 months (p = 0.005); only 11 (38%) reached sufficient vitamin D levels.
Eritrean migrants should be routinely screened for vitamin D deficiency. Single-dose intramuscular supplementation appeared to be insufficient to achieve optimal levels in the majority of participants.
