    Check the strength

    Posted by Reviewer2454698 on Mar 18, 2009

    I've been using melatonin for my son (now 6) over a year now, and the good sleep has helped him learn better. I used to buy the Natrol in the smaller bottle, but the bigger is more economical. Just be aware that the larger bottle is 2-1/2x the strength. I had to make a few phone calls to get the dosage right (we use 1/2 tsp)

    Better than pills

    Posted by Reviewer1081242 on Oct 07, 2009

    Works about 50% of the time and seems to be more effective than the pills (I have tried 11 brands in pill form) and sprays. I have noticed that it is easy to lose the "window of opportunity" for actual sleep if I take it and decide to stay up a bit later to finish watching something on TV. It works but is very gentle and has never left me with a morning after feeling. I have chronic sleep problems and have found that it is best to switch out products because nothing seems to work for more than a week or two.

    HIGHLY recommended!!

    Posted by Reviewer2060946 on Jan 27, 2008

    I have severe trouble with insomnia, have tried many products (including prescription meds, herbal formulas, and even other brands of Melatonin) and this product really helps me to fall and stay asleep all night. What makes this work for me is that it is LIQUID and therefore more easily and quickly absorbed. HIGHLY recommended!!

    Works great, as always!

    We use it to nudge a hyper little boy into sleep. It makes it easier for him to drop off. Dr. had us start with a low dose and increase it until we found the lowest dose that had him asleep within 30 minutes. Too much gives our little guy vivid dreams and way too much gives him nightmares.

    Excellent and can be used for children

    Posted by Reviewer2266986 on May 14, 2011

    My daughter takes 2/3 of a tablespoon and sleeps great with this. No funny pre-sleep hyperactivity as we had with some chewable melatonin before. Highly recommended!

    Keeps me asleep.

    Posted by Reviewer2683170 on May 31, 2011

    I had chronic insomnia (due to chronic fatigue, depression and peri-menopause) for two years. I used the Natrol liquid melatonin in conjunction with the Natrol Sleep 'n Restore tablets. The tablets get me to sleep and this keeps me asleep. I've been using it for over a year now. After two years of NOT sleeping, the sleep I get from this product is bliss! Tastes nice too!

    It seems to help, but other times I cannot tell that it has been taken - the pediatric dr. prescribed this for my 2 1/2-yr old who is on the autism spectrum. It helps her fall asleep (sometimes) but we have not seen it help her stay asleep. But we have noticed it does help some! It doesn't make her groggy, we just use the regular dose at bedtime to help her get to sleep faster (which is very difficult for her).

    Too much preservatives

    Posted by 5062431782095574472 on Apr 15, 2015

    In was hoping to use the melatonin on my scalp. It has too much preservatives in it, and was to sticky when rubbed on scalp. Who sells melatonin with no preservatives in it? I want to use it as a hair growth treatment.

    Too Sweet

    Posted by Reviewer1698292 on Mar 12, 2014

    It is just too sweet, and 2.5mg is not enough for me. I switched to Solgar 10 mg Melatonin, which is super miracle!!!
