Cheap, strawberry-flavored melatonin that melts on the tongue. The best-selling 5 mg strength is more than most adults need; the 1 mg or 3 mg version is a smarter start.

Pros and cons
Magnesi-Om
- Clearly disclosed dose of each magnesium form plus 112 mg L-theanine
- Sugar-free, monk-fruit sweetened; buyers consistently praise the taste
- Finished product retested by a third-party lab to California Prop 65 limits
- Several flavors plus an unflavored 'Naked' version
- About $1.47 per serving at list price, far more than comparable magnesium
- Two-thirds of the magnesium is citrate, and stomach pain and cramping are recurring buyer complaints
- 310 mg is close to the 350 mg daily upper limit for supplemental magnesium
- Sleep evidence for magnesium is weak, and L-theanine is below studied doses
Melatonin Fast Dissolve Tablets
- About $0.11 per tablet at the brand's list price for 150 count
- Single-ingredient formula with no proprietary blend
- Dissolves in the mouth without water; buyers consistently praise the strawberry taste
- The same tablet comes in 1 mg and 3 mg, making it easy to step down to lower, evidence-aligned doses
- Made under cGMPs with batch testing for potency, microbes and heavy metals
- 5 mg is above the 1-3 mg range sleep experts commonly suggest; headaches are the side effect buyers mention most
- Label lists wheat and soy, so it is unsuitable for celiac disease or soy allergy
- No USP, NSF or other named third-party certification, and no batch certificates of analysis on the product page
- Sweetened with xylitol, which is toxic to dogs, so store it out of pets' reach
Our verdicts
Magnesi-Om
Magnesi-Om is a pleasant, transparent and third-party tested drink mix, and some people clearly love it as a nightly ritual. But its magnesium is mostly citrate, the evidence for magnesium and sleep is weak, and the price is steep, so we see it as an overhyped, overpriced option rather than a sleep solution. If you want to try magnesium for sleep, a much cheaper magnesium glycinate is a better first step.

Melatonin Fast Dissolve Tablets
Natrol Fast Dissolve is an inexpensive, transparent and pleasant way to take melatonin, and buyers largely report that it helps them fall asleep. Our reservation is the dose: 5 mg is more than most adults need, so we would start with Natrol's 1 mg or 3 mg tablets and only move up if a lower dose does nothing. Skip it if you avoid wheat or soy.
