Do not buy
Cheap, but tastes bad. I guess it worked but I tossed a big bottle of it and got the higher price Spring Valley 10 kg melatonin which works well. The taste is great (strawberry) and highly chewable.

not happy it said gummies that why l bought them
this product said that they were gummy’s but they’re actually chewable tablets. I can’t eat tablets. I’m very disappointed that it said gummy. That’s the only reason why I bought it.

Not as effective
I don't find the chewable as effective as the ones that dissolve. These don't seem to give me the same relaxing quality.

A Year’s Supply in One Bottle, But 10mg is Potent
I picked this up mainly for the value factor. Getting 360 tablets in one bottle means I don't have to think about reordering for a very long time, which is convenient.
The "fast dissolve" claim holds up well. You don't need water to take them; they break down quickly in your mouth without leaving a gritty residue. The berry flavor is decent—since it is naturally sweetened, it doesn't have that harsh chemical aftertaste that some sugar-free brands have, though it is slightly chalky compared to a gummy.
The main thing to be aware of is the dosage. 10mg is a heavy dose if you are accustomed to the standard 3mg or 5mg tablets. It definitely works to put you out quickly, but I found that 10mg can be a bit overkill for a standard night. The nice thing about the tablet form (vs. a capsule) is that they are easy to snap in half if you want to taper down to a 5mg dose to avoid feeling groggy the next morning. If you have a high tolerance, this is a great bulk buy, but beginners should probably start with half.
