Horbäach5HTP 400mg Capsules | 120 Count | Extra Strength Supplement | Non-GMO, Gluten Free | 5 Hydroxytryptophan

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.

Exactly what I was looking for. If you have a sensitive stomach I will say, I usually never have problems. But these give me a slight tummy ache for about 30min. If you have a sensitive stomach these might not be for you.

I probably suffer from stiff neck muscles due to possibly undiagnosed fibromyalgia which I have actually been carrying around for about 20 years. About 3 years ago I discovered 5HTP and I must say that it saved me from this crippling problem. My advice is to start with the 200mg capsules, since initially, for the first 10 days, taking 5HTP can cause nausea and dizziness. Don't give up, I simply opened the capsule and took half in a glass of water, and gradually increased the dose.You will have to find the right dose because the same amount may not work the same for everyone.

I originally bought this for appetite suppression but it didn't work for that. I'm in perimenopause and have had trouble staying asleep for at least 1 year.I remembered that I had these supplements and started taking them at night. It's only been a few days but I'm sleeping so much better. And when I sleep well, I don't have a crazy appetite like I do without enough sleep.

They work.

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...

Good

Most people need a lower dose than this. I was wondering why i was was experiencing nausea and having nightmares. Now I know that this dose is 4 times what is typically needed. Here i am at 1:30 am writing this review. You need certain nutrients to absorb this such as b vitamins and folate, so if you aren't deficient in those things then I see no reason why you would use this high of a dosage.
