Outcomes
What shoden 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.
Everyday pressure stops running your nervous system hot.
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.
Fewer days where health problems dictate what you can and cannot do.
Good days come more often and bad ones feel less heavy.
Shrinks the gap between hitting the pillow and actually sleeping.
Less of that heavy, worn-out feeling that makes simple tasks feel like a chore.
Fewer wake-ups and more unbroken hours of real rest.
Deeper, less interrupted nights that leave you recharged by morning.
Heart rate, sweating, and tension spike less under pressure.
The background noise of worry, irritability, and low mood gets quieter.
Names, conversations, faces, and details stick instead of dissolving.
Organize priorities, switch tasks, and catch mistakes more easily.
Conversations and everyday interactions feel more natural and fluid.
Higher one-rep max, stronger grip, and more force from every muscle group.
