“Glucosamine and chondroitin
2 are compounds that are naturally found in the cartilage that cushions your joints,” explains
Dr Suzanne Wylie, GP and medical adviser for
IQdoctor.
“They're often taken together in product form, as they’re believed to work synergistically to support joint health, especially in people with osteoarthritis.
“Glucosamine contributes to the production of glycosaminoglycans,2 which help build and repair cartilage,” she explains. “While chondroitin2 helps cartilage retain water and may inhibit enzymes that break it down, which could reduce inflammation and improve joint function over time.”
While some studies suggest this product duo might ease pain and boost mobility in people with mild to moderate osteoarthritis, Dr Wylie stresses that evidence3 remains mixed, so it’s hard to say definitively how well they work.
That said, she notes they’re generally safe for most people to take, but there are a few caveats to know.
“If you have a shellfish allergy, double-check the label, as some glucosamine is derived from shellfish,” she advises.4 “And if you’re taking blood thinners like warfarin, or you have diabetes, it’s important to speak with your GP before starting, as there may be interactions.”
Ultimately, when it comes to glucosamine and chondroitin, Dr Wylie affirms they’re low-risk options worth exploring, but should always form a part of a broader plan for managing joint pain and you should always discuss these options with your GP.
“Make sure to pair them with exercise, a good weight management plan and schedule regular check-ins with your doctor to monitor any changes,” she adds.
