If you want to fall asleep faster or reset your schedule after travel, this delivers a well-studied dose. **Melatonin** at 3 mg per capsule sits right in the middle of the 0.5–5 mg clinical range — enough to meaningfully support your sleep-wake cycle without pushing into the higher doses that tend to cause next-day grogginess.

The formula is minimal: just melatonin, rice flour, and a veggie capsule. No added sleep herbs, no fillers to worry about. If you already know melatonin works for you, this straightforward approach means you're getting exactly what you need without extras that may or may not help.

Research suggests that lower doses (0.5–1 mg) can be just as effective as higher ones for many people. If you find 3 mg leaves you groggy in the morning, you might actually respond better to a lower dose — more isn't always more with melatonin.

Rice FlourFiller

Rice-based ingredients carry risk of inorganic arsenic contamination (FDA and Consumer Reports). Rice accumulates arsenic from soil at higher rates than other grains. Used as a cheap filler — adds nothing beneficial.
