The main ingredients in Osteo Joint Ease are glucosamine, chondroitin and methylsulfonylmethane; the most common side effects of these supplements are stomach problems, such as excess acid, diarrhea and heartburn, according to WebMD. Headaches, swollen feet and ankles, and skin irritation are also possible side effects, according to Drugs.com.
Since glucosamine is sourced from shellfish, people who are allergic to shellfish or iodine should not take glucosamine supplements, says Mayo Clinic. Those with diabetes, with asthma or at risk for bleeding should also use caution with glucosamine. Supplements, although not regulated as drugs, can interact with medications or medical conditions, so patients should consult with their doctors to verify that the supplement is safe.
The source of chondroitin is animal cartilage. Chondroitin has side effects similar to those of glucosamine, according to WebMD. High doses of chondroitin can contain too much manganese, which can cause nervous system damage. A doctor can recommend a safe dosage. As with any medication, pregnant or nursing women should consult with their doctors before taking the supplements.
Vegans or vegetarians avoid glucosamine and chondroitin because they are sourced from shellfish and animal cartilage, respectively. If diet, allergies or medical conditions do not allow the use of Osteo Joint Ease, patients can ask their physicians for information about suitable alternatives.
