This site's own routine guidance is written around a breakfast-anchored, once-daily schedule — worth considering what that means if you'd specifically prefer evening use instead.
This site recommends taking the capsule with breakfast and staying consistent at the same time each day — it does not specifically address or recommend evening use as an alternative in the materials reviewed.
Since this formula contains no caffeine or stimulants, per this site's own claims, the typical concern behind avoiding evening stimulant use may not apply the same way — worth checking your own bottle's specific label guidance rather than assuming either way.
