Can I Take glucosamine and chondroitin Together?

SUMMARY:

Glucosamine and chondroitin are commonly combined for joint support and are generally considered safe to take together for most people when used as directed. People taking anticoagulant medications, those with shellfish allergies, diabetes, or other medical concerns should check with a clinician before combining supplements.

ADDITIONAL NOTES:

Both are dietary supplements often used together for osteoarthritis/joint symptoms. Common adverse effects are mild gastrointestinal upset and headache. There are reports that glucosamine (and to a lesser extent chondroitin) can affect anticoagulant (warfarin) activity and may increase bleeding risk—monitoring is advised if you take blood thinners. Glucosamine is commonly derived from shellfish shells and may be a concern for people with shellfish allergy; discuss safety with your provider. Use caution in diabetes and other chronic conditions and review all supplements with clinicians or pharmacists.
