How to choose a combination supplement
- Key ingredient amounts — Compared with our single-ingredient guidelines: melatonin starting at 0.5–1 mg, 5 mg at most; elemental magnesium 200–400 mg; theanine 100–200 mg as in single products; ashwagandha withanolides 10–30 mg (KSM-66 300–600 mg). Points off for lots of token ingredients at 10–20 mg each
- Melatonin upper limit — Points off if the label dose is over 5 mg a day; 'Not recommended' at 10 mg. Also check whether you can take less (1 gummy or capsule, half a scoop of powder)
- Stacked calming ingredients — 'Not recommended' if melatonin is stacked with 2 or more calming herbs at meaningful amounts, like valerian, hops, passionflower, ashwagandha or California poppy. Valerian: take caution if you have liver problems
- Hidden amounts — 'Not recommended' if main ingredients are bundled in a proprietary blend that hides how many mg of each. If only small amounts of herbs are blended, it's noted in the reasons
- Better than buying separately? — If magnesium and melatonin are each at a proper dose, the plus is fewer pills. If it's mostly melatonin with a sprinkle of other ingredients, a melatonin-only product is better
- Cost per day — Price ÷ count × the label's max daily serving. Not used in the verdict, only noted in the reasons
- Label check — Products we could not verify in the NIH DSLD label database get 'Depends on your needs' at best (regardless of brand). Review counts and star ratings are not used in the verdict. OTC sleep aids (diphenhydramine, doxylamine) and homeopathic products are not supplements, so they're 'Not applicable'
