Glucosamine and Pregnancy: An Introduction
Is Glucosamine Safe for Pregnant Women?
Even though glucosamine is a dietary product available without a prescription, this does not automatically imply that it is safe for use during pregnancy. It should never be assumed that a supplement is safe for pregnant women just because it is a "natural" product.
However, there is one small study that suggests glucosamine may be safe for use during pregnancy. Women who took the supplement did not have a higher risk of problems, compared to women who did not take it. However, this study was quite small, perhaps too small to discover potential problems.
Because it is not known for sure if glucosamine is safe during pregnancy, it might be wise for a pregnant woman to avoid this supplement until more information is available.
If you are pregnant, it is always a good idea to ask your healthcare provider before taking any medication or supplement. If a natural medicine practitioner recommends that you use glucosamine during pregnancy, it would be wise to check with another healthcare provider, just to be safe (and to get a second opinion).
