Tastes great and works very good.
Size: 200 Count (Pack of 1)
I take melatonin often and this has always been the brand and type I have used. It works great for me. Love that it is chewable - easy to take right before bedtime.

GOAT
Size: 200 Count (Pack of 1)
Welcome back to the world of sleep. This stuff is my holy grail - knocks me out gently after about 30 minutes. The flavor is wonderful and I look forward to taking it on nights where I have trouble falling asleep (most nights). It works better than any other brand I have tried and I have tried lots.

"Lozenges" are the new "Sublingual Tablets"
Size: 200 Count (Pack of 1)
This is going to be more a public service than a true review (read before complaining).... I just bought three bottles of these "orange sublingual tablets." I always check the mfr's. label to make sure that they are, indeed, sublingual tablets before opening them, in case I need to return a "wrong item." All three bottles stated "orange flavored lozenge" on the front of the label. The seller had stuck two (2) paper labels on the back, one (both?) of which stating "sublingual," but I'm thinking that there's something deceiving, possibly fraudulent, going on here. I tried to lift a label on one bottle, as someone before me tried to do (who apparently returned it). No luck; didn't want to destroy something that at that point I was going to return. I searched several places on the Internet for Source Naturals Melatonin Lozenges -- couldn't find that anywhere, even on Source Natural's web site. I took advantage of their "Contact (us)" link and briefly told them what I found. This was their reply, in its entirety:
"Source Naturals appreciates your time and interest. Our “Melatonin Sublingual” products are intended as dietary supplements and are regulated by the U.S. Food and Drug Administration (FDA). Recently, FDA stated to us its position that only drug products could use the term “sublingual” on product labels. As such, to make clear that our products are dietary supplements and not drugs, we are updating our product labeling to “Melatonin Lozenges” with instructions for each unit to be dissolved slowly in the mouth prior to swallowing. However, there has been no change in the formulation or effectiveness of our Melatonin products. If you have any questions concerning your use of a particular dietary supplement, please consult your qualified health care professional. Please keep in mind that Source Naturals provides a 100% satisfaction guarantee. If you try any Source Naturals product and are unsatisfied for any reason, you may take the product back to the retailer originally purchased for a refund, exchange, or credit."
So, there you go. Same product, different description, thanks to the FDA, who after 10+ years of "evaluating" a popular European sunscreen which is far more protective than what's available in the USA, finds time, instead, to screw around with this minor confusing, non-descriptive stuff that is essentially of no help to the public. It seems obvious to me that all sellers should update the photos of the bottle (purchasers are going to compare and then return their items if discrepancy is discovered; a lot of unnecessary time and expense wasted) and revise their product description that briefly summarizes what the statement from Source Naturals says. Anyway, I'm glad to learn that the "lozenges" are the same sublingual tablet we all love. (Please do not complain that this is not a true review; I don't care, and have no regret.)

Great results for over a year (as needed).
Size: 200 Count (Pack of 1)
This brand was recommended by a staff member at my local co-op; they generally know a good deal about their products. I've used it for a year and I get great results with the sublingual tablets. They dissolve under my tongue in 10-15 minutes. The orange flavor is nice, but remember to rinse all of the toothpaste from your mouth or it could affect the citrus taste. I have no "next day" sleepiness from these. This dosage is high, so I'd recommend starting at the 1 mg dose and go from there. Amazon offers a great price; I still shop at the co-op for fresh foods and spices, but I'll switch to Amazon for these tablets.
