This site states these two specific figures directly: 1 capsule a day, 30 capsules per bottle.
Worth confirming the simple math: 30 capsules at 1 per day equals exactly a 30-day supply, consistent with this site's own stated bottle-count language elsewhere on the page.
This site separately recommends taking the capsule with breakfast at the same time each day — worth reading that routine guidance alongside this basic daily-count fact.
