Better Sleep Gummies are made with TruCBN™, the CBN ingredient studied in this trial. For 4 weeks, adults looking for better sleep were randomly assigned one of three TruCBN™ doses, 4 mg melatonin or a placebo. The 50 mg dose, the same amount of CBN in each Better Sleep gummy, significantly improved sleep quality compared with placebo, with no significant difference from melatonin.*
