Melatonin Dosage Guide: How Much Should You Really Take?

Most people are taking far too much melatonin. Pharmacy aisles offer 3 mg, 5 mg, even 10 mg per serving, but research shows lower doses are safer and often more effective.

What Does Melatonin Do?

Melatonin regulates your circadian rhythm — telling your body when to sleep and wake. It is produced by the pineal gland in response to darkness.

The Problem With High Doses

Your body produces 0.1 to 0.3 mg naturally. Taking 5 to 10 mg floods your system with 15 to 100 times the natural amount. Side effects include vivid dreams, grogginess, headaches, and receptor desensitization that makes the problem worse over time.

Optimal Dosing Research

Studies show 0.3 to 1 mg is the most effective range. A landmark study found 0.3 mg was as effective as 3 mg with far fewer side effects. Melatonin works as a signal, not a sedative — a small clean signal is all your brain needs.

The Yu Sleep Approach

Yu Sleep uses a deliberately low melatonin dose combined with natural melatonin from tart cherry extract. With GABA, L-Theanine, and 5-HTP, the formula addresses sleep from multiple angles so you don’t need high melatonin alone. Try Yu Sleep risk-free.
