This gummy delivers **Melatonin** at 3mg — solidly within the 0.5–5mg range used in clinical research for sleep onset and circadian rhythm support. That's the dose doing the heavy lifting here, and it's well-placed for helping you fall asleep faster.
**L-Theanine** at 100mg sits right at the bottom of the studied range (100–250mg), giving you a baseline dose for promoting relaxation before bed. The combination with melatonin makes sense — theanine calms without sedating, while melatonin signals your body it's time to sleep.
The herbal extras — **Chamomile**, **Passionflower**, and **Lemon Balm** — are each dosed at 16–17mg, which is a fraction of the amounts used in clinical research (chamomile studies use 500–1,500mg of extract, passionflower 250–500mg, lemon balm 300–600mg). At these doses, you're getting trace amounts that are unlikely to contribute meaningfully to sleep support. The melatonin and theanine are carrying this product.

Caramel ColorColor
Class III and IV caramel colors contain 4-methylimidazole (4-MEI), classified by IARC as Group 2B (possibly carcinogenic to humans) in 2011 (Monograph Vol. 101). California Prop 65 lists 4-MEI as a known carcinogen; products delivering >29 mcg/day require a cancer warning label. NTP TR-535 (2007) found 4-MEI caused lung tumors in mice. Major cola brands (Coca-Cola, Pepsi) voluntarily reformulated 2012-2014 to reduce 4-MEI below California thresholds. Because labels never specify Class I (sugar + heat only, safer) vs Class III/IV (ammonia-process, contains 4-MEI), consumers cannot verify which they're consuming. Combined with the additive's purely cosmetic purpose, the risk:benefit ratio is unfavorable for any supplement.
