Sleep Gummies (Blackberry Zen)

OLLY Sleep is one of the best-known melatonin gummies in US drugstores, big-box stores and on Amazon. A two-gummy serving provides 3 mg of melatonin, 50 mg of L-theanine and small amounts of chamomile, passionflower and lemon balm extracts in a blackberry-flavored gummy with a hint of mint.

The melatonin dose is the strongest part of the formula. At 3 mg it sits at the top of the 1-3 mg range that Johns Hopkins sleep specialists suggest, so it is more measured than the 5-10 mg gummies that crowd the shelf. The supporting ingredients are a different story: a 2025 systematic review found benefits for sleep with 200-450 mg of L-theanine a day, four to nine times what this serving provides, and the three botanicals are included at 16-17 mg each, far below amounts typically used in studies. Treat this as a melatonin gummy with a light calming garnish.

Quality is a genuine strength. OLLY Sleep is listed in NSF's certified dietary supplement database, which means NSF tests that the label matches the contents and screens for contaminants. The label also states that the gummies are made with higher active levels than listed to preserve potency through expiration, a common practice worth knowing about when you are dosing melatonin.

Buyers and creators on TikTok consistently praise the taste and say they fall asleep faster without a groggy morning; the recurring complaints are nausea or headaches for some users and split opinions on whether it is worth the price. Each serving has 2 g of added sugar and contains gelatin, so it is not suitable for vegetarians.
