Overdose of multivitamins increases the risk of breast cancer, researchers

Researchers at Karolinska Institutet in Stockholm, Sweden have conducted a study over usage of multivitamins involving 35 thousand women aged 49 to 83 years, which lasted more than ten years. Over a decade of monitoring, 974 women were diagnosed with breast cancer. Specialists also took into account factors such as age, family history of breast cancer, weight, eating of fruits, vegetables and consumption of alcohol, physical activity and smoking. It was found that the women who regularly used multivitamins, had 19% more risk of breast cancer than among other study participants.

Experts believe that there is no need to mindlessly consume multivitamins on a regular basis and expect the solution of health problems, as claimed in the advertisement of the range of drugs. Over dose of vitamins causes a number of health problems. Moreover, synthetic vitamins are no substitute to natural ones, since they are absorbed by the body in different manner, explained the researchers.
