11 hours agoHow Much Melatonin Should You Be Taking? And Should You Be Taking It at All?
First of all, let's back up. What is melatonin? It's the hormone your brain produces naturally as part of its circadian rhythm, or the internal clock your body has to keep you on a natural, daily sleep schedule. Your pineal gland is in charge of making it, and sunlight signals it to slow down production so you can wake up and go about your day. Though your brain is already producing melatonin, the idea of taking a supplement is that it jump-starts your sleep cycle.
