This site's own FAQ addresses this directly: take four sprays daily, directly into the mouth, preferably under the tongue or toward the back of the throat for better absorption.
Worth noting this site names two acceptable placements — under the tongue or toward the back of the throat — rather than a single fixed instruction, worth reading that as built-in flexibility for comfort.
This FAQ answer separately adds: use it at roughly the same time each day so support stays consistent — worth reading both the placement and timing instructions together as the complete routine.
