Don’t assume that dietary supplements “can’t hurt, might help.” An example of this fallacy is a recent study in JAMA Network Open, which found that high intakes of vitamins B6 and B12 were associated with increased risk of hip fractures.
Researchers looked at more than 75,000 women in the Nurses’ Health Study, who were followed for two decades. The increased fracture risk was seen in women taking at least 25 milligrams a day of vitamin B6 (about 15 times the daily RDA) and those taking at least 25 micrograms a day of B12 (about 10 times the RDA).
Dietary intake of the vitamins, without supplement use, was not associated with increased fracture risk.
