Melatonin by Superior Source
Size: 100 Count (Pack of 1), Style: Melatonin 1mg
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.

My favorite Melatonin supplement
Size: 100 Count (Pack of 1), Style: Melatonin 1mg
I have used this for a few months and really like it. I had previously used a spray that for some reason had added B6 (>2000% RDA) and I developed toxic levels of Vitamin B6 so had to switch. I love that this doesn't have any added garbage including no added flavors, artificial sweeteners or artificial dyes. The taste is fine. It's not candy and isn't supposed to taste like candy. It is just a bland taste that I hardly notice. Dissolves quickly and easily. Love it.
