"I have tried many different brands of 5-HTP, but I keep coming back to this one. I take 1 upon rising and 1 at dinner. I can tell the difference in how I sleep with this product. I value every hour I get and this product helps me sleep soundly (without waking up to hear my husband snore... :-)))"
"I have used Jarrow 5HTP for years and have found it to be the best quality and recommended by my Dr. Ordering this product from Vitacost has saved me quite a bit of money over walking into a health food store or a retail outlet carrying Jarrow products."
"I tried another brand of 5-HTP a few months ago and didn't notice that it was doing anything to help me sleep. I tried Jarrow's and am sleeping soundly. My husband is having the same results. This is a great product."
"I am had trouble sleeping for sometime and have tried all the natural sleep aids on the market today. Jarrow's Formula 5 HTP gets me to sleep every night. Glad to have found something that works so well."
