food and nutrition, male fertility, supplements, lactation, vitamins during pregnancy

Q: My husband and I are into weight lifting. We usually take supplements like creatine and a protein drink. Are those safe when we TTC and during pregnancy?

A: There is no data evaluating the safety of creatine supplements or other athletic performance drugs on male fertility, pregnancy, lactation, or childhood. Like with any food or supplement in question, it's best to check directly with your doctor or midwife.
