Is Glucosamine Safe to Use During Pregnancy?

A study published in the Journal of Women’s Health concluded that there is little currently available data to suggest that glucosamine causes risks for adverse fetal effects during pregnancy.  However, the currently available data is very limited.  It would be advisable to avoid the use of glucosamine during pregnancy regardless.

“CONCLUSIONS: These limited data suggest no increased risk for major malformations or other adverse fetal effects following the use of GLS during pregnancy. “
