Glucosamine is an amino sugar derived from the chitin of shellfish and is
used by the body to support healthy joint structures. Chondroitin
complements Glucosamine and works synergistically to provide optimally
There is no current recommended daily dosage for glucosamine, however, most
people do best when taking 500 milligrams to 1500 milligrams daily, whether
alone or in combination with other supplements (like Chondroitin, Omega-3s
or MSM supplements). Studies show the 500 to 1,500 dosage range helps:
lower inflammation and help reverse autoimmune reactions
preserve joint health
reduce joint pain and tenderness
protect and repair the gut lining
fight irritation to the stomach, bladder, and intestines
treat inflammatory bowel disease and leaky gut syndrome
rebuild tissue and stronger bones following fractures or injuries
What are Glucosamine and Chondroitin Sulfate?
Glucosamine and chondroitin sulfate are substances found naturally in the
body. Glucosamine is a form of amino sugar that is believed to play a role
in cartilage formation and repair. Chondroitin sulfate is part of a large
protein molecule (proteoglycans) that gives cartilage elasticity.*
Both glucosamine and chondroitin sulfate are sold as dietary or nutritional
supplements. They are extracted from animal tissue: glucosamine from crab,
lobster, or shrimp shells; and chondroitin sulfate from animal cartilage,
such as tracheas or shark cartilage.*
What do they do?
Past studies show that some people with mild to moderate osteoarthritis
(OA) taking either glucosamine or chondroitin sulfate reported pain relief
at a level similar to that of nonsteroidal anti-inflammatory drugs (NSAIDs)
such as aspirin and ibuprofen. Some research indicates that the supplements
might also slow cartilage damage in people with OA. Definitive results
about the effects of these supplements are expected from an in-depth
clinical study currently being conducted by the National Institutes of
What do I look for?
Because dietary supplements are unregulated, the quality and content may
vary widely. If you decide to take these supplements:
• Choose products sold by large, well-established companies that can be
• Read the product labels carefully to make sure the ingredient lists make
sense to you. If you have trouble, ask your pharmacists for help.
• Be sure to consult your doctor before deciding to try these supplements.
• Make sure that OA is the cause of your pain.
• Do not stop or reduce your current prescribed medications without talking
with your doctor.
How do I take them?
If you decide to take these supplements, consult your doctor about the
proper dosage. The amount used in studies of glucosamine was 1,500 mg per
day and in studies of chondroitin sulfate, 1,200 mg per day was used. You
can try the supplements along with your current medications for six to
eight weeks. If you don't experience any difference in your symptoms within
a few months, you probably will not get any relief from using the
Are there side effects?
The most common side effects are increased intestinal gas and softened
stools. If you experience these problems, you might want to try another
supplement brand before you stop using them altogether. More studies need
to be done to confirm the safety and effectiveness of the supplements. Be
sure to contact your doctor if you notice any unusual or new symptoms while
you are taking them.
• Children, women who are pregnant, and women who could become pregnant
should not take these supplements. They have not been studied long enough
to determine their effects on a child or on a developing fetus.
• Because glucosamine is an amino sugar, people with diabetes should check
their blood sugar levels more frequently when taking this supplement.
• If you are taking chondroitin sulfate in addition to a blood-thinning
medication or daily aspirin therapy, have your blood clotting time checked
more often. This supplement is similar in structure to the blood-thinning
drug heparin, and the combination may cause bleeding in some people.
• If you are allergic to shellfish, consult your doctor before deciding to
take glucosamine. In most cases, however, allergies are caused by proteins
in shellfish, not chitin, a carbohydrate from which glucosamine is
British Research study finds:
The purpose of this study was to examine the effects of oral glucosamine
supplementation on the functional ability and degree of pain felt by
individuals who had regular knee pain, most likely due to previous
articular cartilage damage, and possibly osteoarthritis.
Subjects were randomly supplemented with either glucosamine (G) (n=24) or
placebo (P) (lactose) (n=22) for 12 weeks at a dose of 1000 mg per day.
Over this period, four testing sessions were conducted, with changes in
knee pain and function assessed by clinical and functional tests, (joint
line palpation, a 3-meter "duck walk" and a repeated, walking stair climb),
two questionnaires (the Knee Injury and Osteoarthritis Outcome Score (KOOS)
and the Knee Pain Scale (KPS)) and participant subjective evaluations.
The clinical and functional test scores improved with time (main effects:
p<0.05, p<0.01) but there were no significant differences between the
two groups. The questionnaire results also recorded a significant main
effect for time (p<0.05), but the glucosamine group was found to have
significantly better KOOS quality of life scores at weeks eight and 12
(p<0.05), and lower KPS scores (p<0.05) at week eight than the
placebo group. On self-report evaluations of changes across the 12 week
supplementation period, 88% (n=21) of the glucosamine group reported some
degree of improvement in their knee pain versus only 17% (n=3) in the
These results suggest that glucosamine supplementation can provide some
degree of pain relief and improved function in persons who experience
regular knee pain, which may be caused by prior cartilage injury and/or
osteoarthritis. The trends in the results also suggest that, at a dosage of
1,000 mg per day, the majority of improvements are present after eight
