Outcomes
What chondroitin sulfate actually does, by outcome
Each row is one outcome with effect size, evidence base, the dose that worked in trials, and time to first effect. Magnitude tiers come from native-unit MCID where available, Cohen's d otherwise.
Bathing, dressing, climbing stairs, and daily tasks stay within reach.
Your joints stop being the first thing you notice every morning.
Lower intensity, fewer flares, and longer stretches of relief.
Less pain, less stiffness, quieter inflammatory signals inside the joint.
Fewer days where health problems dictate what you can and cannot do.
