Great product!
Size: 100 Count (Pack of 1), Style: Melatonin 1mg
This is the best melatonin if I have trouble waking up in the middle of the night, I take 1 mg. Under my tongue and I can fall back to sleep. Excellent product. It's good enough that I only take one. Much better than other brands I have tried!

Fast Working
Size: 100 Count (Pack of 1), Style: Melatonin 1mg
I have a hard time staying asleep. I took this product the first day and slept very well. I would recommend this highly. Dissolves Faunder the tongue and works sooner than capsules or pills.

I've bought this melatonin repeatedly for years. It works gently and naturally to help me drift off to sleep and wake rested and ready for the day. I always get the smallest dose 1 mg

So far it does help me with becoming drowsy for sleep
Size: 100 Count (Pack of 1), Style: Melatonin 1mg
So far this melatonin helps with making me drowsy, but I still take 1/2 a prescribed sleeping pill with it. Normally, within a half hour I am sleepy. I have not tried taking it by itself yet. I am a petite build, so I think my size factors in to how well it works for me. Flavor is okay. Easy to take melting it under my tongue. Price is okay. I like that it is sublingual and limited added ingredients. I don't usually take chamomile due to being sensitive to it in the past, but seems to be okay in this pill. It also seems to help me with staying asleep for a longer period of time.
