I am 13 weeks pregnant. i have been taking cinnamon with chromium picolinate and just discovered it can be dangerous. have i done damage to my fetus?

Hard to know: While you need small amounts of chromium in your diet, its usually in your prenatal vitamin in sufficient amounts. Cinnamon bark in high doses has been associated with miscarriage, so if beyond 12 weeks you are probably fine. Chromium at the doses you may be taking are again not recommended it lowers blood sugar and inhibits growth of body fat (your baby dose need some of this).

Unlikely: Although chromium can be quite toxic, most of the problem has been with the hexavalent type. That is the kind used to make things shiny. The picolinate salt uses trivalent chromium. That kind is much safer. Cinnamon has not typically caused problems. The preferred agent for diabetes in pregnancy is insulin, though metformin is used sometimes. Work with your doctor for the best option for you

Not sure: Never take any substance unless your physician thinks you need it. I would discontinue it unless your Dr. prescribes it for you!
