Are glucosamine and chondroitin sulfate safe for me?
The most common side effects with these supplements are indigestion and nausea. Remember that dietary supplements such as these are not regulated the U.S. Food and Drug Administration so quality and content may vary widely. Children and women who are pregnant, plan to become pregnant, or currently breastfeeding should not take these substances. Patients allergic to shellfish should speak with their physician before taking glucosamine. Patients with diabetes should check their blood sugar more frequently if they choose to use glucosamine. Patients taking blood-thinners choosing to take chondroitin sulfate should have their prothombin (liver protein) time checked more often. Be sure to discuss with your physician before starting to take these supplements.
