Rated 5 out of 5 by from Happier these Days This is the supplement that I preferred over SAM-E, St. John's Wort, L-Tryptophan & Valerian for my mental boost every day. The serotonin level up helps me maintain a clearer focus. I just wish I could get more for the price. Otherwise, this stuff kicks butt!

Rated 5 out of 5 by from aids in sleeping We started using this item to help get a good night sleep. We were getting up three to four times each night. We saw a difference immediately. Now we only get up once a night.

Rated 5 out of 5 by from Best Price I have found I started taking the 5HTP from Natrol prior to menopause, and at the same time having to travel back and forth to Atlanta. I found that my mood swings were less and my moods were more even keel, I wasn't as hungry all the time, and it helped me sleep better at night. I ran out for about a week and I could feel myself getting agitated over the littlest things and I wasn't able to sleep as well. I will not be with out it again. I love this product and would recommend this to every one

Rated 5 out of 5 by from great for focus and the blues Most people use this to stave off depression or the Blue's but I have noticed that when I taking a small 50mg dose of this in the Morning with a Panax Ginseng product it really improved my focus and attention span! I can't take it at night because it causes me to sleep walk and then feel like it was a dream the next day-kinda scary when you live alone! Anyway, great product!
