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
Sleep Gummies (Blackberry Zen)
- 3 mg melatonin per serving, within the range sleep experts commonly suggest
- Listed in NSF's certified dietary supplement database for label accuracy and contaminants
- Every ingredient amount disclosed, with no proprietary blend
- Buyers and TikTok reviewers consistently praise the blackberry flavor and easy chew
- L-theanine (50 mg) and botanicals (16-17 mg each) are far below studied doses
- About $0.56 per serving at the brand's list price, roughly five times a basic melatonin tablet
- Some buyers report nausea or headaches, and buyers are split on value for money
- Contains gelatin and 2 g added sugar per serving
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.

Sleep Gummies (Blackberry Zen)
OLLY Sleep is a well-made, third-party certified melatonin gummy with a reasonable 3 mg dose, and most buyers find it pleasant and effective. The L-theanine and herbal extracts are too small to add much, so you are mainly paying for melatonin in a tasty, convenient form at several times the price of a basic tablet.
