Who is OPA Nighttime Formula for?
It's for adults who'd rather take one evening formula than line up several separate bottles. It may suit you if you want:
- A melatonin capsule you take 20–30 minutes before bed
- Melatonin together with L-theanine, chamomile, lemon balm and passion flower
- A capsule instead of a gummy, powder or tea
- A caffeine-free evening supplement
It isn't the right pick if you're avoiding melatonin, St. John's Wort or 5-HTP, or if you're under 18, pregnant or nursing.
