Most people feel something the first day, within about 30 minutes of taking your gummy. It's subtle, not dramatic. That's by design.
Within four weeks, the bigger shift shows up. Reishi is an adaptogen it builds with consistent daily use and this is where most people say it clicks: staying level through the parts of the day that used to get to them.
From there, consistency is doing the work. Keep taking it daily and steady stops being a good day and starts being your baseline.
