Movement beats rest
The instinct with a sore knee is to rest it. For most everyday joint stiffness that is the wrong move — cartilage has no blood supply and depends on movement to circulate synovial fluid.
Weight matters more than any supplement
Every kilogram of body weight puts roughly four kilograms of load through the knee when walking. Losing five kilos removes about twenty from each step.
The supplement evidence, fairly stated
Glucosamine and chondroitin show modest benefit in some trials and none in others. Boswellia and turmeric have better short-term comfort data. None of it works quickly; eight to twelve weeks is the honest timeline.
Do not forget vitamin D and calcium
Joint pain and bone health are separate problems that often arrive together. Low vitamin D causes muscle and bone aching that is easy to mistake for joint pain.
When to see a doctor
Swelling, heat, redness, morning stiffness lasting over an hour, or pain that wakes you at night. Those are not supplement problems.
