Overview
Melatonin is the hormone that signals darkness to your body. Supplementing can help with sleep onset, jet lag, and shift work. It's one of the most commonly used sleep aids worldwide.
Our take
Less is more with melatonin. Most products are way overdosed—0.3-0.5mg is often more effective than 5-10mg. Use it for timing, not sedation. Great for jet lag, less ideal for nightly use.
