Does tart cherry juice actually induce deep sleep or is it just another expensive placebo?

I have been reading so much lately about the purported benefits of tart cherry juice for sleep quality. My local health store clerk swore up and down that drinking a glass before bed helped her reach deep sleep faster because of the natural melatonin content. I tried it for a week, and while it definitely tasted good, I couldn't tell if my deeper sleep was due to the juice, the placebo effect, or just the fact that I was exhausted from work. I find myself wondering if the concentration of procyanidins in these bottles is even enough to influence the human circadian rhythm significantly. Has anyone here experimented with this or other herbal hacks like Valerian root or Chamomile tea? I’m really curious if you’ve found genuine success with natural alternatives or if I’m just wasting my grocery budget on overpriced fruit juice. What is the one natural remedy that actually made a measurable difference for your sleep cycle?
