Is Melatonin Safe? The Truth About the Popular Sleep Aid

The Short Answer

Melatonin is safe for short-term sleep reset, but the way it is sold and regulated is dangerous. Because it is categorized as a dietary supplement rather than a drug, the quality control is virtually non-existent.

A staggering 88% of melatonin gummies are inaccurately labeled, with some containing up to 347% more melatonin than claimed. If you need it for jet lag or occasional sleeplessness, stick to third-party tested brands and keep the dose under 3mg.

Why This Matters

Melatonin is a hormone produced by your brain's pineal gland, not an herbal extract like chamomile. Taking high doses of a synthetic hormone every night can disrupt your body's natural sleep-wake cycle. How Much Melatonin To Take

The supplement industry routinely pushes massive doses that far exceed what your body naturally produces. Most standard supplements offer 5mg to 10mg, which is up to 30 times the physiological optimal dose. This is why many people wake up feeling groggy or experience vivid nightmares.

The risk is even higher for children. Pediatric emergency room visits for melatonin ingestion have skyrocketed, with roughly 11,000 ED visits between 2019 and 2022. Kids are mistaking these inaccurately labeled gummies for candy, leading to accidental overdoses. Are Gummy Vitamins Bad For Kids

What's Actually In Melatonin Supplements

• Synthetic Melatonin — The active ingredient in almost all supplements is made in a lab. While bio-identical to your natural hormones, the doses are usually dangerously high.
• Cannabidiol (CBD) — A 2023 JAMA study found hidden CBD in several supposedly "pure" melatonin gummies. One gummy contained zero melatonin and 31.3mg of CBD. Supplements Contain Claims
• Serotonin Contamination — Poorly manufactured melatonin can sometimes contain serotonin as a byproduct, though reputable brands screen for this.
• Sugar and Fillers — Gummy formats are typically packed with corn syrup and artificial dyes to make them taste like candy.

What to Look For

Green Flags:

• USP or NSF Certification — It guarantees the bottle actually contains the exact dose listed on the label. Usp Verified Meaning
• Low Doses (0.3mg to 3mg) — Less is more when it comes to melatonin, and low doses prevent next-day grogginess.
• Tablet or Liquid Formats — These are significantly easier to manufacture accurately compared to gummy formats.

Red Flags:

• Proprietary Sleep Blends — Brands use these to hide cheap ingredients so you don't know the exact dose you are taking.
• Gummy Formats — Gummies are notoriously difficult to mix evenly, leading to massive dosage variations from batch to batch.
• Doses Over 5mg — Mega-dosing melatonin is unnecessary for sleep and increases the risk of side effects like nightmares.
