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.
