Customer Comments

"Thank you WWL for your prompt service. I live in Australia and I received my order within 6 days. Your melatonin is the best I have used and I have used several different brands before, no hang-over next day and I'm sleeping much better." - B from Sidney, Australia

"This is the second time to order this product for my grand father and my mother. They said, it has been really helpful for their sleep. And thank you so much for good products ,safe and fast delivery to Korea." - T.H.K., Korea

"Just a quick note of 'thanks' for great service. Found your site by chance when researching melatonin on line. My husband and I are totally satisfied with the product, just ordered 2 more. We have recommended your site to the folks at the office, and even though our orders are tiny, we appreciate you and wanted to let you know. Cheers, and thanks again." - J&B J., Canada

"A few years ago, my mother told me that your Melatonin solved all problems she'd suffered. Because S/H to Japan is expensive, I had to buy more to keep them in stock for my mother. 50 bottles are enough to live for about 5 years. She said that she would take them until she dies. ... She trusts your brand. Please note that you have a fan even in Japan." - U.Y., Japan
