iHerb Customer Reviews

This product does not seem to work for me

Posted by iHerb Customer on Nov 10, 2017 | Verified Purchase

I have been taking this product for 1 months without any significant change, no better sleep so far, so not sure if it works.......

Thanks for your feedback!

This product really works and makes my life livable.

I have prostate cancer which causes urinary blockage, resulting in 2 or 3 visits to the toilet every night. This causes great difficulty in getting back to sleep again. However if I take 1 tablet every time I wake I quickly fall asleep again, and I get up reasonably refreshed the next day. Without them I would have bad insomnia and be unable to function. I don't notice any side effects. Melatonin is a natural hormone produced in the body, though perhaps not always in sufficient quantity as we get older. The tablets are small and easy to swallow with a sip of water. They are reasonably priced, and delivery from iHerb is fast to here in Australia. All in all an excellent product and I recommend it to all insomnia sufferers.

Thanks for your feedback!

Great Product

Posted by iHerb Customer on Jul 16, 2017 | Verified Purchase

I'm extremely sensitive to any tablets and often have horrible side effects. However this product is fantastic. No reactions of difficulties at all. Great product at a great price.

Thanks for your feedback!

Wrong Tablets

Posted by all animals not most dogs on Jul 12, 2017 | Verified Purchase

I ordered 5 mg but was sent 3 mg. I presume returning them would be expensive so will use them, just more tablets per dose. I hope my next order will be correct.

Thanks for your feedback!
