In the following study, we mainly investigate the effects of static magnetic field (SMF) (128 mT, 1 hr/day during 5 consecutive days) on 25-hydroxyvitamin D3 and calcium homeostasis.
Wistar male rats, weighing 50-70 g, were randomly divided into four experimental groups:
- control,
- SMF-exposed rat,
- co-exposed rats (the last day and after exposure rats received a single dose of vitamin D per os) and
- supplemented with vitamin D group (without exposure to SMF).
Exposure to SMF induced a decrease of plasmatic 25-hydroxyvitamin D3 level (P<0.001). While, calcium and phosphorus levels were not affected (P>0.05).
The same treatment failed also to alter body, relative liver and kidney weights. Interestingly, oral supplementation with vitamin D corrected hypovitaminosis D induced by SMF.
Likewise, the same treatment failed to alter calcium homeostasis.
More studies are needed to evaluate how SMF induces hypovitaminosis D.

Rats got about 1/10 Tesla for 1 hour per day for 5 days
Vitamin D levels dropped from 22 ng to 14 ng
Patients getting MRI receive 0.5-3.0 Tesla for about 1/2 hour, thus about 10X as intense, but perhaps only 1/10 of body
MRI also used to diagnose:
- Concussions (traumatic brain injury) getting big press coverage, vitamin D might be both a cause and a solution
- Overview MS and vitamin D
- Alzheimers-Cognition - Overview
- Knee surgery reduced vitamin D by 40 percent in 2 days – May 2011 was it the surgery or the MRI which reduced the vitamin D levels?
Passengers in magnetically levitated trains get about 1/20 Tesla (Note: this study, while made in Wisconsin, was published in Japan)
