5HTP 400mg Capsules | 120 Count | Extra Strength Supplement | 5 Hydroxytryptophan | Non-GMO, Gluten Free

I'm going through menopause. These have taken away the rage and calmed me down. But they make me nauseous and put me to sleep. THIS IS NOT THE 5 HTP FOR ME BUT I GAVE IT 5 STARS BECAUSE I'M GUESSING THAT THIS IS WHAT ITS CUSTOMERS ARE LOOKING FOR. Unfortunately for me I prefer the other brand I bought off Amazon a few years ago which was actually 750 mg not 400 mg. I recommend this product for anyone going through menopause if they have a problem with sleeping.

I came to 5-HTP through The Craving Cure by Julia Ross, which uses amino acid therapy to address neurotransmitter deficiencies at their root. My pattern was classic low serotonin: racing thoughts at bedtime, late-night cravings for something sweet, and broken sleep. I’d tried melatonin for years — it got me to sleep but left me feeling foggy and heavy every morning, sometimes for hours. The protocol I follow is simple: one capsule (200mg) on a completely empty stomach, 45 minutes before bed. Within an hour, the mental chatter that typically runs at full volume after 10pm just stops. The calm is real but not sedating. What surprised me most was the end of what I call “night hunger” — I no longer wake at 2am with an urgent craving for something sweet. That alone made this worth it. One honest note: this is not an overnight fix. I saw mild improvement in the first week, but the full effect took about two weeks to settle in. Give it time. If your sleep problems come from physical discomfort, pain, or a medical condition rather than anxious or racing thoughts, this formulation addresses the serotonin pathway specifically — it may not be the right tool for you. Four months of consistent use, zero grogginess, and a mind that actually quiets at bedtime. Five stars because it delivered exactly what melatonin never could.

This stuff is a life saver for people that are not very responsive to SSRIs. I use it daily and take it at night since it is tryptophan after all. Helps encourage sleep no doubt and only has a mild grogginess of you take it too late and wake up too early. Mild stomach upset if on empty tummy so I suggest taking w a cracker or two. Otherwise I highly recommend for anyone struggling w mood imbalances or even after a weekend vacation of partying just to have as a stabilizer. This has replaced pharmaceutical need for me thank goodness. But please always talk to a doctor first before trying to replace any medications as it can be dangerous to just stop meds but know this can also be coupled w meds, w dr approval, to help assist a prescriptions intent. ***Never just stop any prescription based on a randoms review!*** Lol.

The first one I took made hot and nauseous I had to induce puking because I was feeling sick after that I felt better and took a shower because I was sweating everywhere, I found out later you have to start with 50 mg then 100 and so on,I didn't wanna feel nauseous the next time so I split the capsule , I'm using this because I couldn't fall sleep or wake up at night so this I noticed made me sleepy earlier and I wake up maybe once at night but still wake up around 7am then get sleepy around 10-11 so I can't get a job in the morning but it's helping

I deduce that it is affective. However, after taking 2 pills followed by dinner, I came to the strong conclusion of rather: Take 1 pill, twice daily. For me, two pills (800 mg) altered my sense of normalcy. I suggest 1 pill at a time first....

I use 5-HTP in the evenings to relax and head towards a night of sleep. It has a moderate relaxing effect, which is enhanced if taken with Valerian. If you have problems with sleep, or need some mild relaxant, the 5-HTP may help. There are many manufacturers. I use this one because it says that it is lab tested and follows GMP (good manufacturing practice). This gives some assurance of quality that not every manufacturer provides.

Quality or concentration has dropped significantly, this is not the same product I have been taking for over a year. My last order from February is lacking concentration or is just ineffective. I take this for migraines and old bottle of this brand (200 mg dose) actually works, while taking this new bottle supplement is like taking a sugar pill - no effect despite being higher dose (400 mg). Was my first choice for HTP 5 for a few years, switching to NOW as this Amazon/Horbach brand has lost my trust. I saw another recent review by someone who takes htp5 for muscle cramps, and they too question if there is any htp5 in the pills they tried in 2025 - other brands work, this one does and I think it's because they changed concentration or supplier and new batches are just not effective. If I had more money I would send in a lab to get it tested to see just how much htp 5 is there now vs older bottles from previous orders placed in 2024. Do better! I can't return as window passed, wish I could get a replacement to see if my bottle was just a bad batch...

Seems to be a high quality product and works well.

Lo compré por recomendaciones de amistades que tienen problemas para dormir y conciliar el sueño. La verdad que es muy bueno, te da bastante sueño y en la mañana despiertas bien descansado sin ningún efecto secundario como somnolencia, aturdimiento, cansancio que los somníferos generan

Lo uso como complemento alimenticio indicado para los trastornos de la menopausia

Es un buen producto para generar serotonina y elevar su cantidad
