Consult your healthcare provider before combining Thorne Melaton-3 with any prescription medications. Melatonin can interact with blood thinners, immunosuppressants, diabetes medications, and blood pressure drugs. While the NSF Certified for Sport label ensures purity, drug interactions still depend on individual circumstances.

Melatonin supplements are not recommended during pregnancy or breastfeeding due to insufficient safety data. Despite Thorne's high manufacturing standards, the safety of supplemental melatonin during pregnancy has not been established. Consult your OB-GYN before use.

Yes, Thorne Melaton-3 is NSF Certified for Sport, meaning it has been tested for over 200 substances banned by major sporting organizations. This certification makes it one of the safest melatonin options for competitive athletes subject to drug testing. It is trusted by US Olympic teams and professional sports leagues.

At the 3mg dose, possible side effects include drowsiness, headache, dizziness, or vivid dreams. Some users may experience next-day grogginess if taken too late. If side effects occur, you could try opening the capsule and taking half the powder to reduce the dose to approximately 1.5mg.

Short-term use up to 3 months is well-supported by research. Longer-term use has not raised serious safety concerns in studies up to 2 years. Thorne's clean formula with no fillers or unnecessary additives minimizes the risk of cumulative exposure to unwanted substances.

Take one capsule 30-60 minutes before your target bedtime. As a standard capsule, it requires time to dissolve and absorb. Consistency in timing is important — take it at the same time each night to help reinforce your body's natural sleep-wake cycle.
