Certainly vitamins are beneficial to health, but excessive consumption of supplements can bring unexpected risks with it.

shows that less than a quarter of supplements are taken with the recommendation of a health professional.

Most of them taken over the counter.

Survey indicates a tendency to switch from multivitamin pills to targeted supplements - mainly fish oil and vitamin D.



For most people this dietary fervor is harmless - except for a small hole in the pocket - and for anyone whose dietary composition is inappropriate or lacking in a special medical condition, dietary supplements can do wonders.





But it's also worth remembering that high doses that significantly exceed the daily dose recommended by, for example, the Institute of Medicine at the National Academy of Sciences of the United States, can be dangerous.









The study, A reminder of this can be found in a recent study linking vitamin B overdoses of some types with an increased risk of pelvic fractures.The study, published last May , examined the dietary habits of nearly 76,000 postmenopausal women who have been participating in nursing health research for several decades.





And surprisingly, they found that subjects taking high doses of vitamin B6 (35 mg and above a day), along with B12 (20 micrograms or more), were found to have a nearly 50 percent higher risk of pelvic fracture compared to those taking lower or no doses.

High doses of B6 alone increased the risk. The study corroborated similar findings from the large Norwegian survey published in 2017 and examined whether these vitamins and folic acid can reduce the risk of heart attacks and strokes in patients with atherosclerosis.





Unfortunately, they were found to be of no use at all, and much to the researchers' surprise, a link was found between high doses and pelvic fractures.





It is unclear why vitamins cause this effect.





There are two possible mechanisms, Excess vitamin B6 can be toxic to the nervous system, and therefore increase the risk of falling, followed by pelvic fracture.





The nurses taking high doses exceeded 30-20 times the recommended daily dose.





The dosages needed to get side effects would be much higher, but we don't know for sure.





Another possibility is that B6 competes with estrogen for binding to the steroid hormone receptors, thus disrupting the role of hormones in maintaining bone health.
