Melatonin supplements often come with an expiration date, which serves as the manufacturer's assurance regarding the potency and safety of the product if consumed before the indicated date on the bottle or label. However, not all melatonin products are labeled with an expiration date. Further research is necessary to determine the safety of melatonin products beyond their expiration dates.
Melatonin is a naturally occurring hormone produced in the brain, regulating the body's sleep-wake cycle. Synthetic melatonin found in supplements is utilized by individuals to address various sleep-related issues such as insomnia, jet lag, and certain sleep disorders in children.
Between 1999 and 2018, there was a significant five-fold increase in the usage of melatonin among individuals. As more individuals contemplate the use of this supplement to improve sleep, understanding the expiration of melatonin can empower them to make informed choices regarding their sleep hygiene and health.
Melatonin Expiration Dates
In contrast to prescription drugs, the U.S. Food and Drug Administration (FDA) does not assess the safety or effectiveness of supplements or regulate their labeling.
In 1979, a law was enacted in the U.S. mandating that all drug manufacturers affix an expiration date on their products. This date serves as the manufacturer's assurance that the drug maintains full potency and safety until the indicated expiration date.
Given that the FDA categorizes melatonin as a dietary supplement rather than a drug, manufacturers are not obligated to imprint an expiration date on the bottle. Nonetheless, many supplement manufacturers opt to include expiration dates on their labels or bottles.
Individuals who prioritize the use of high-quality supplements may consider melatonin products approved by the United States Pharmacopeia (USP), an independent nonprofit organization. The USP establishes standards for healthcare products in the U.S. Products endorsed by the USP have met the organization's rigorous criteria for quality, purity, potency, labeling, and packaging.

Differences Between melatonin and zetia
Melatonin:
Melatonin is a hormone naturally produced by the pineal gland in the brain. It plays a key role in regulating the sleep-wake cycle and is commonly used as a supplement to treat insomnia, jet lag, and other sleep disorders.
Zetia (Ezetimibe):
Zetia is a medication used to lower cholesterol levels in the blood. It works by reducing the absorption of cholesterol from the diet in the small intestine. Zetia is often prescribed along with statin medications to further reduce LDL cholesterol levels.
Alternative to melatonin
Lifestyle Changes:
Making changes to your lifestyle and bedtime routine can have a significant impact on sleep quality. This includes maintaining a regular sleep schedule, creating a relaxing bedtime routine, avoiding electronic screens before bed, and ensuring your sleep environment is comfortable and conducive to sleep.
Is Expired Melatonin Safe to Take?
While some medications have undergone studies indicating their safety even after expiration dates, further research is required to ascertain whether this applies to melatonin. If you possess expired melatonin, it is advisable to consult with your doctor or a pharmacist before consuming it.
A potential issue with taking medications or supplements beyond their expiration dates lies in the possibility of alterations to their chemical composition over time. This alteration could lead to reduced efficacy due to diminished strength, or they may degrade into different substances that elicit varied effects.
How Long Does Melatonin Last in the Body?
After ingesting a dosage of 1 to 5 milligrams, the peak levels of melatonin in the body usually occur around 60 minutes, a common range for many oral melatonin formulations. Within eight hours, melatonin levels typically normalize.
The term "half-life" denotes the duration required for the body to eliminate half of the original concentration of a drug. For melatonin supplements, the half-life is approximately 20 to 50 minutes.
How to Properly Store Melatonin
Melatonin, like all supplements and medications, should be stored in a cool, dry, and dark place to maintain its potency effectively.
It is advisable to avoid storing melatonin in areas prone to heat and humidity, such as medicine cabinets or vehicles. Instead, store melatonin in its original container in places like kitchen cabinets, closets, or dresser drawers.
Always ensure that the lid of the melatonin bottle is tightly closed and store the supplement in an area inaccessible to children. It's important to prevent children from accessing medications and supplements, including melatonin, as they can be harmful if taken improperly.
In 2020, U.S. poison control centers received more calls related to children ingesting melatonin than any other substance. Keeping medications and supplements out of reach of children helps prevent accidental or intentional overdose.
If you have questions about the optimal storage of melatonin or any other dietary supplement, consulting with a pharmacist is recommended. Pharmacists can offer guidance on the proper storage methods for various medications, including melatonin.
How to Dispose of Expired Melatonin Products
There are several safe methods for disposing of expired melatonin products, including participation in drug take-back programs and at-home disposal procedures.
Drug take-back programs offer a safe means to dispose of supplements like melatonin outside of the home. These programs are often sponsored by local law enforcement, pharmacies, and community groups throughout the year. Pharmacists can provide information regarding drug take-back programs available in your community.
If a drug take-back program is unavailable in your area, you can still safely dispose of melatonin at home. Some supplements and medications can be safely flushed down the toilet or drain, as indicated on the product's packaging.
Another method involves mixing expired melatonin with used coffee grounds or kitty litter before placing the mixture in a plastic bag or container with a secure lid. Subsequently, seal the container or tie the plastic bag securely before placing it in the trash.
Responsible disposal of expired melatonin products helps prevent misuse by individuals of all ages, including pets.
Consulting with a pharmacist or healthcare provider is advisable if you have questions about the proper disposal of expired melatonin.
Conclusion
The safe disposal of expired melatonin products is crucial to prevent misuse and ensure public safety. Drug take-back programs offer convenient and secure options for disposing of supplements like melatonin, while at-home disposal methods, such as flushing or mixing with coffee grounds or kitty litter, provide alternative solutions where take-back programs are not available. By following proper disposal procedures, individuals can contribute to safeguarding their communities and environment from potential harm. Additionally, consulting with pharmacists or healthcare providers for guidance on disposal methods ensures responsible handling of expired melatonin and promotes overall wellness. Together, these efforts foster a safer environment and promote informed decision-making regarding medication and supplement usage.
