Top Reviews from the United States
Great deal for 200 mg
"I am really happy with the double strength 5 htp. I previously had been taking two of the regular Now 100 mg, and decided that the double strength was a better deal. I was nervous that it wasn't going to really be the same dosage, but I have felt wonderful taking these over the past couple months without any complaints. I was skeptical at first because these 200 mg pills are the same size as the 100 mg pills, but the double strength pill is clearly more full than the regular. I informally tested this by squeezing both pills, the 100 mg gave way a lot while the double strength was very firm, which suggests to me that there is truly more product in the double strength pill."
Do not mix with SSRIs!
"I'm giving 5 stars because I dont wanna hurt their reviews with my mistake. Taking this product with SSRIs resulted in serious stomach pain and the need to "evacuate" until your bowels are completely empty. Take my suffering as a lesson. I tried it twice just to ensure I hadnt eaten something bad. (my scientific method) I learned through pain so you don't have to. When taken after a three day lapse of medication I had no adverse effect."
