Oops. Less is more, it appears. The 39,000 women in the Iowa Women’s Health study delivered us some surprising results recently. The authors set out to measure reduction in mortality rates from different supplements but what they found instead was
an increase in risk of mortality.
After controlling for other factors, taking a daily multivitamin increased the absolute risk of mortality 2.4%. Here were the results for other supplements:
- Vitamin B6 4.1% absolute increase risk of mortality
- Folic acid 5.9% absolute increase risk of mortality
- Iron 3.9% absolute increase risk of mortality
- Magnesium 3.6% absolute increase risk of mortality
- Zinc 3.0% absolute increase risk of mortality
- Copper 18.0% absolute increase risk of mortality
About the only good news for supplements was a risk reduction of 3.8% with calcium supplements. Do I think taking a multivitamin will kill you? No. Do I think you need supplements if you have a balanced diet? No. Fish oil, calcium and vitamin D aside, it appears postmenopausal women don’t need supplements.

Life has a 100% risk of mortality. How do you blame deaths on vitamins?
Seems like something is really fishy with this study.

Unless you're suffering from Hashimotos Thyroiditis, in which case you almost certainly do, especially B12, Folic Acid, Zinc Selenium and Magnesium.
There's a backlog of information to the contrary of this one recent study, so I think people would be wise to be wary of it until it is corroborated.
