I'm also sort of a naturalist and very anti-pharmaceutical. I don't care what anyone says, but this country is driven by "quick fixes" and "happy pills," which of course NEVER solve the problem. I can honestly say that this supplement has saved me in every way that I needed to be saved.I could not for the life of me figure out why my anxiety got worse as an adult where I started having panic attacks and then fearing that I would have panic attacks which brought on more panic attacks. I won't be a hypocrite. I have a script for Xanax but I RARELY take it. When used on occasion, it is a brilliant med, but I don't want to need to take it.I first tried 5-HTP and I'm a very happy person so when I started getting really agitated, I knew something was weird. Then, I read a bunch of reviews where you aren't supposed to drink within 6 hours of taking it and you shouldn't take Ibuprofen. So, essentially, you aren't supposed to live a real life or get cramps or headaches because just have to suffer through them. If I received major benefit from it, I would have gone ahead and taken it. After getting moody, I look again at the reviews for L-Tryptophan.I can honestly say that this has CHANGED ME! No more panic. Sleeping amazingly. I'm not stressed. I hardly have any anxiety. Where have you been all my life, L-Tryp... seriously???I have friends that are on SSRI's AND Benzos daily and they STILL have panic attacks. If ALL of that medication isn't at least getting rid of your issues, why the hell would you continue to take it and say to yourself, "This seems very wrong..."After having anxiety daily and panic attacks often and literally beginning to question doing things because I didn't want to have panic, I knew that I needed to find SOMETHING to help me or I would literally be nuts by the time I was 40.Friends, this seriously have saved me. I have tried a LOT of stuff (I mean A LOT), but in getting to the root of my stuff (OCD/anxiety), I figured that low serotonin was the bottom line. It would seem then that raising my serotonin levels naturally would be key.I cannot say enough how amazing this product has been. I wish I could give it 10 stars and an Academy Award!Thank you, Source Naturals for making an excellent product. I will be buying a lifetime supply!UPDATE: it's over a month later and I haven't had a panic attack or taken Xanax once!! I think it's a combo of working with your thoughts as well but I really do believe in this product. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Skeptical of this kind of thing, but wow... *by H***E on Reviewed in the United States on July 12, 2011* TL;DR Version:I'm incredibly skeptical of alternative medicine, but it works.Long Version:I've been wrestling with severe PTSD for years, including depression, anxiety problems, and sleep disorders. But getting treated for PTSD is difficult and I hate the side-effects of psychiatric Rx's. Still, I've bordered on major mood problems that made me desperate for something. I was willing to check myself into an institution, except my insurance provider wouldn't cover enough of the expense.Now let me say right up front that I am a skeptic. I don't put much stock in alternative medicine, as a rule. Yeah, okay, Valerian works, opioids and certain other "herbs", but most of the effective ones are Schedule-narcs, making it irrelevant for the don't-want-to-go-to-jail type of person. But I did my research and found some medical literature supporting the use of L-Tryptophan for my symptoms, so I thought I'd give it a try. But I wasn't hoping for anything. In fact, I explicitly expected this NOT to work.Wow, I was wrong. This works so wonderfully that I wonder when the big pharma co's are going to catch on and forced the FDA to take this off the OTC market.Regimine:Three capsules (500mg) first thing in the morning on an empty stomach (this is important)Two capsules mid-day an hour before lunch.Two capsules an hour before dinner.I also take melatonin supplements before bed. This helps, but don't overdo it or it can be counter-productive.Effect:It is very subtle at first. It took me a couple of weeks before I realized that I was actually feeling fine for a change. That might not sound like a big deal, but if you're suffering with PTSD, trust me: feeling "fine" is a joy. I am able to deal with life without getting freaked out and spiraling down the rabbit hole. Things just don't upset me the way they used to. I can handle the regular life "stuff"; everything doesn't become Instant Crisis Freakout. In fact, it's rather hard for me to get upset about anything. If that sounds like heaven to you, then this is the supplement you want.When I came to my PMS week, I was worried I'd find out that I was just imagining the effect, but nope -- I made it through that week with only a slight mood swing. Nothing serious.I ran out about a month ago and didn't bother to re-up because one of the features of my PTSD that this does nothing for is the procrastination (note that; this won't fix everything). It was a week or so, and I started noticing my stress returning. In another week, it was bad again, so I bought a new bottle. It's been a week, and I'm feeling good again.People seem to take this for a lot of reasons, and I can't speak to any other than anxiety and depression. It did not do anything for my insomnia directly. It was more of an indirect effect of making me chill enough that I wasn't going to sleep rigid with worry. Still, it doesn't put me out or anything. For that, I use the melatonin.Note: If you're trying to make up your mind whether to take this or 5-HTP, go with this. It's the precursor for the stuff in 5-HTP, and works a lot better. You might try combining this with Emergen-C (not just regular Vitamin C capsules) and a B-6 liquid supplement for even better effects. I noticed a difference with those, but YMMV.All in all, I'm very happy with this. ### ⭐⭐⭐⭐⭐ 朝のんでます *by マ***サ on Reviewed in Japan on July 27, 2022* 薬のサイズ(カプセル)が大きくてのみにくいですがコスパはよいです朝ドーパミンを出すために飲んで出勤してます人によっては夜飲んで睡眠の質を高めるために使用するかたもいるとのこと効果としては自分にはあってるかなと思います --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/10015062-source-naturals-l-tryptophan-500-mg-90-caps](https://www.desertcart.sn/products/10015062-source-naturals-l-tryptophan-500-mg-90-caps) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-05-25*
