The safety and efficacy of supplements degrade over time. Gummies containing melatonin, like other medications and supplements, possess an expiration date indicating the period during which the manufacturer can still guarantee the products full potency and safety. Exceeding this date raises concerns about the compound’s effectiveness and potential changes in its chemical composition.
Consuming supplements past their expiration date may not result in noticeable adverse effects, but it is plausible that the melatonin content diminishes significantly, leading to reduced or nonexistent sleep-promoting effects. Historically, expiration dates were established to safeguard consumers from ineffective or potentially harmful substances, ensuring they receive the intended therapeutic benefit and minimizing risks from degradation products.
