“What vitamins to avoid during the second trimester?”

Half way there!
Unless you have any medications/supplements prescribed by your OB/GYN, just continue taking your daily prenatal vitamin.

Thank you for your question. First, I wish to congratulate you on this pregnancy. Hopefully you may be beyond the morning sickness often associated with early stages of pregnancy. Regarding advice for what to take & what not to take during one's pregnancy is best discussed with your prenatal care provider. Such matters can be associated with your underlying health factors & that of your baby. Best wishes to you for a happy & healthy pregnancy. With your next prenatal visit, or ask this question of your provider with a call to the office whichever is sooner. GABrowne MD. FRC
