Natrol is one of the most popular manufacturers of melatonin supplements, and their fast dissolve formulas are among their best known. But as I outlined in my review of Natrol’s fast dissolve melatonin, there are some definite issues beyond the fact that I didn’t find it particularly effective. And it all comes down to ingredients.
As far as standalone, single active-ingredient melatonin supplements, I much preferred Life Extension’s timed release formula (read my full review on that here). These are also vegetarian tablets without so many mystery ingredients.
For me, the gimmick of quick-dissolve tablets isn’t worth it when there are other supplements that help me get significantly better rest.
