Outcomes
What curcumin 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.
Less pain, less stiffness, quieter inflammatory signals inside the joint.
Thinner, less red, and less widespread patches over time.
Your joints stop being the first thing you notice every morning.
Mornings start with movement instead of waiting for your joints to thaw.
Shrinks the gap between hitting the pillow and actually sleeping.
Less cramping, rumbling, and unease throughout your gut.
Lower intensity, fewer flares, and longer stretches of relief.
The background hum of worry that colors everything gets quieter.
Quiets the health worries and body tension that build with age.
Quiets the overthinking that hijacks execution right before you compete.
Joints move more freely, especially after rest or first thing in the morning.
Less upper-stomach heaviness, burning, and acid discomfort after eating.
Quiets the nervous-system overdrive that keeps you wired at bedtime.
