    This product makes my heart race - literally!

    Posted by Reviewer2603395 on Oct 22, 2009

    I LOVE I-HERB and I like the Source Natural product line, but I've tried these tablets twice now, and both times I experienced a short term heart rhythm elevation - very scary. I got it slowed down with deep breathing, but apparently melatonin can have side effects. Also at the full dosage - 3 mg - I felt druggy for two days. I then took 1/4 of the full dosage a second time and didn't get to sleep at all. I'm not saying this formulation would create the same reaction for everybody - it may be that my body is hyper-sensitive to increased levels of melatonin, but I did not like this product. Used two tablets - then tossed it. Calm Forte was recommended to me by a friend - will try that next.

    My 10 year old has always had troubles relaxing at night enough to fall to sleep, even as an infant. She was advised by her holistic healer last year that this would help her to relax and get the rest she needed so we tried it. Ever since she started taking this product there hasn't been a problem and we are so pleased to find something non narcotic. Because it is sublingual she takes it 20 minutes before bedtime and by the time she hits the pillow she is out and wakes up feeling refreshed and not groggy.

    No sleep problems when we use this nice tasting sublingual shortly before bedtime.

    I must be sleeping very soundly after taking these because I wake up in the morning and I feel great all day!

    Tired from, not of, this product!

    Pleasant taste. I took only one tablet and was surprised at how quickly I felt sleepy (about 30 minutes). Source Naturals Melatonin in now part of my nightly routine.
