Product Overview


  • Non GMO Validated
  • Dietary Supplement
  • For Occasional Sleeplessness

Melatonin is a neurohormone produced in humans by the pineal gland. A favorite of travelers, it governs the body's circadian rhythms, helping the body ease into restful sleep. Melatonin is also a potent antioxidant.

Source Naturals Timed-Release Melatonin is formulated to allow for a gradual release of the active ingredient during an approximate six hour period. This provides the body with a more even absorption of melatonin.

1 to 3 tablets at bedtime. Do not take more than 5 tablets daily unless recommended by your physician.

Dibasic calcium phosphate, microcrystalline cellulose, stearic acid, magnesium stearate, and silica.

Seems to work

Posted by 4942806512380612584 on Dec 02, 2016

Purchased for my anxious 22 yo daughter who often has trouble getting to sleep and periodically has bouts of insomnia. She has taken 2 before bed on several occasions and slept well. Seems to work for her. I believe her circadian cycle is regulating better.

Very helpful to induce sleep

Posted by 4938553114271656822 on Nov 30, 2016

I bought melatonin as I was having many sleeplessness nights. I am a bit cautious when I start a having a supplement, so I ordered the minimum dosage. I have one tablet when needed. Occasionally I may need two tablets. My aim is to bring my sleep under control by re-educating my body to sleep from 10.30pm tp 6.30am. My sleep routine has improved a lot. although I still wake up in the middle of the night to go to the bathroom, but I go back to sleep immediately!

Helped my restless mind to calm before sleeping.

Posted by 5346856791636060959 on Nov 29, 2016

I originally purchased this for my husband to try to relax him before bed in the hopes that he may snore less. It sadly didn't help with this purpose, and we're still struggling to diagnose why he's snoring. But I decided to give this a try myself, to try to calm myself before bed. I have a particularly stressful lifestyle but I don't do well with things like meditation or yoga as I'm restless and overthinking a lot of the time. This helps to stop my racing mind enough to drift off into a deep enough sleep to get proper rest. I start with 1 and it wasn't enough but 2 on nights when I have no other option tends to do the trick. I deducted a star because these are fairly pricey for only 1mg dose. I bought 1mg knowing I could add if it wasn't enough. I suggest starting at 2mg/3mg and breaking in half if needed. These might be great for teens or older folks who don't have as much of a tolerance, though. Overally happy, just not a very big dose for the price.

Great for Sleep!

I've been having trouble sleeping recently, and my circadian rhythm was all over the place. So I've been trying this product for a few weeks, and with just one tablet, I'm peacefully sleeping without any grogginess when I wake up.
