Are you aware that 5-HTP – an amino acid supplement that supports serotonin levels – can raise cortisol levels and leave you feeling “wired-tired”? You may be able to relate to this if you’ve ever used 5-HTP to help with anxiety and insomnia and ended up feeling more anxious and more wide-awake despite your exhaustion and need for sleep. You feel “wired-tired” and it’s not pleasant at all.
Both 5-HTP and tryptophan, used as supplements, help to boost serotonin levels so you can feel happy, calm, sleep well and not crave carbs in the afternoon/evening. They also help with panic attacks and phobias, lack of confidence, depression, negativity, imposter syndrome, PMS, irritability, anger issues, pain/fibromyalgia, TMJ and anger. I typically have my clients with low serotonin symptoms start with a trial of tryptophan because I see such excellent results with this amino acid. That being said, some people simply do better on one versus the other and you may do better with 5-HTP.
However there is one big caveat with 5-HTP. I don’t recommend 5-HTP when a client has elevated cortisol levels because we know that it can raise cortisol levels in certain individuals. This can leave you feeling agitated, cranky, as well as wired and yet tired at the same time.
In this 2002 study, L-5-hydroxytryptophan induced increase in salivary cortisol in panic disorder patients and healthy volunteers
Salivary cortisol levels were measured in 24 panic disorder patients and 24 healthy volunteers, following ingestion of 200 mg L-5-hydroxytryptophan or placebo.
The experiment was carried out in the afternoon, “when basal cortisol secretion is more stable.” The first saliva sample was obtained at 1pm and the subjects ingested the 200mg 5-HTP at 2pm. Additional saliva samples were obtained at 2:30pm, 3:00pm and 3:30pm.
They report the following:
A significant rise in cortisol was observed in both patients and controls following ingestion of L-5-hydroxytryptophan. No such effects were seen in the placebo condition.
Here are a few additional comments and my thoughts:
- This study was done to find evidence for “serotonin receptor hypersensitivity in panic disorder” and not specifically to test for the effects of 5-HTP on cortisol levels but it serves this purpose rather nicely (and it’s one of many similar studies, some of which measure plasma cortisol levels)
- Keep in mind 200mg of 5-HTP is a large starting dose. It’s typical to start with 50mg so may be a factor to consider
- In this study they did not assess cortisol levels beyond the 1.5 hours from ingestion of the 5-HTP. It would have been useful to see when levels started to go down
- We would want to consider the ramifications of using 5-HTP for weeks (whether it’s 50 or 200mg). What impact would that have on cortisol and the adrenals? (I am not aware of a study like this having been done)
- I’m also not aware of a study being done with 50mg but if you feel worse and feel “wired-tired” with 5-HTP and switch to tryptophan (the equivalent starting dose is 500mg) and your anxiety and other low serotonin symptoms resolve then you have found your solution
- You may be wondering: “could I use 5-HTP to raise my low cortisol levels”? Theoretically yes and possibly very short-term. But I would question the timing since 5-HTP and tryptophan are best dosed mid-afternoon and later. This is when we would expect our cortisol levels to be on the downward slope as we end our day. I’d also want to nourish the adrenals with B vitamins and herbal adaptogen and remove the trigger/s that are leading to low cortisol.
If you suspect low serotonin symptoms and are new to using the amino acids and do not have my book I highly recommend getting it and reading it before jumping in to taking supplements: The Antianxiety Food Solution – How the Foods You Eat Can Help You Calm Your Anxious Mind, Improve Your Mood, and End Cravings.
There is a complete chapter on the amino acids and one for pyroluria, plus information on real whole food, sugar and blood sugar, gluten, digestion and much more. If you’re not a reader there is now also an audible version.
Here is the Amino Acids Mood Questionnaire from The Antianxiety Food Solution and additional information on Anxiety and targeted individual amino acid supplements: a summary
Please also read and follow these Amino Acid Precautions.
This lists The Antianxiety Food Solution Amino Acid and Pyroluria Supplements that I use with my individual clients and those in my group programs.
Have you used 5-HTP with success? Or have you used it and felt “wired-tired”? Have you correlated the success or failure of your 5-HTP use with your salivary cortisol levels?
If you switched from 5-HTP to tryptophan did you have success with that?
If you’re a practitioner is this something you see with your clients/patients and take into consideration?
Feel free to post your questions here too.
Sorry to hear that you have had some negative responses. You are one of my favourite people for information. In Canada, I have so far had difficulty finding GABA + Tryptophan. I am able to buy 5-HTP, & sometimes have had good results for relief of anxiety. I bought some GABA in the USA, but the dosage was too high, so I am trying to remove some of the powder from the capsule & take it sl, It doesn’t work all the time for me, so far. Thank you for all the information. Donna
Trudy, I cannot begin to imagine the number of people who have been helped
by your work and the incredibly valuable things you share. I’ve used holistic
practitioners for years and I know first-hand how valuable supplements can be.
Very grateful for your work,
Carol
5-HTP came to my attention about a month ago by a naturopath, after I asked about melatonin, I was told not to take melatonin as it wrecks the bodys melatonin making factory then I would have to take melatonin the rest of my life. I was sold a sleep aid that has 5htp in it and was told the 5htp helps out the body make melatonin, now I have run out of the sleep aid, I have gone back to the herb Valerian.
Because of mood issues, – dysthymia, irritability, negative thoughts, and low energy, my doctor recommended 5HTP. I started on 50 and have worked up to 200 daily (which I’ve been taking at bedtime for over 2 years now). On the occasions when I cut back, mood issues returned which does suggest to me it’s working. Lately I am experiencing problems with disturbed sleep, waking during the night which I had not associated with the 5HTP. Shall I switch to tryptophan?
Thank you so much for your blogs, book, lectures. You really make a difference Trudy!
Your posts do not stop amazing me! I have been diagnosed with hpa axis dysfunction with high cortisol at night, my psychiatrist had me on 200 mg of 5-htp and my sleep was getting worse and worse! I had to stop taking it because I was going to get the DUTCH test done by Geneva and noticed I slept much better without it…. I am so grateful for your posts!

Thanks for sharing and glad you have made the connection. Keep in mind too that 200mg 5-HTP is considered a relatively high dose (certainly as a starting dose). I start clients on 50mg and increased based on symptoms. If the 5-HTP is making things worse we switch to tryptophan, also starting low and increasing based on need.
This is such a great article. I am a Gut Health Dietitian and the company I work for test 11 gut-realted metabolites to help us understand how well the gut is doing the variety of processes it supports. Among the 11 metabolites we test tryptophan, serotonin and tyrosine. I recently started working with client who was recommended 5THP and they reported having headache and poor sleep after taking it. Our assessment shows that he also has above normal tryptophan levels as well. We are trialing a smaller dose of 5HTP, but I am not sure recommending L-TRP would be a great next step due to his high TRP. THoughts?
Rachel
Thanks for the feedback. Too much 5-HTP can do this and it can also happen if it’s not needed. Also some do better on tryptophan vs 5-HTP.
I am curious to learn about the metabolites you test and their interpretation. Do they correlate with symptoms i.e. do you find low serotonin on the test correlates with low serotonin symptoms?
If you are new to the amino acids (and other anxiety nutrition solutions like gluten/sugar/caffeine removal, blood sugar control, gut health, pyroluria etc) my book “The Antianxiety Food Solution” is a great place to start. More here https://www.everywomanover29.com/store/aafsbook.html

Hi, this is interesting, I have read about quite a few people who have experienced averse events such as increased anxiety, heart rate, and insomnia when taking 5-htp. They say things like, it must be “serotonin syndrome”, or too much serotonin, but I think they are mistaking it for a rise in cortisol.
“Severe serotonin syndrome is rare, and almost exclusively caused by SERT inhibitor + MAO inhibitor co-treatment [67]. 5-HTP has never been associated with serotonin syndrome in humans. In published reports, > 250 humans have been dosed with 5-HTP + a SERT inhibitor, with no serious adverse events [35–37, 57–59, 68–70].” https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5728156/
I have been experimenting with tryptophan and 5 htp. I made the mistake of starting high at first. My first night, I tried 1000mg of tryptophan, I felt calm at first, and then later very wired, anxious, and could not sleep. The next night I tried 500mg, same thing. I then tried 250mg, same thing where I feel calm at first, and then wired. Next day I tried 100mg of 5-htp, felt sweaty, wired, and anxious again. Next day I tried 50mg of 5-htp in the morning… and I found it to be tolerable… the lower dose seems to makes a big difference.
So… is it common that starting at a low dose, prevents the adverse events, and that most people can gradual increase the dosage until the intended benefits becomes effective? With SSRIs research shows short term use can increase cortisol, yet long term downregulates HPA activity and lowers cortisol. Would 5-htp work in the same way? Do you find this lines up with peoples experiences in using it?
Cody
Your comments about serotonin syndrome may well be true in some instances.
We always start at a low dose and go up from there until all benefits are seen.
I’m not aware of 5-HTP doing this long-term.

Well then perhaps your statement isn’t correct: ” 5-HTP and tryptophan are best dosed mid-afternoon and later” might be wrong for some individuals. Perhaps your statement doesn’t fit everybody: blanket statements aren’t always correct. Since your don’t back up that statement with whatever reason you have for stating it, unfortunately it isn’t useful.
Some people could be considering using 5htp for OTHER reasons that are NOT “to avoid carb cravings in the evening”. Not all women have that evening carb craving problem. I certainly don’t. Some of us have different problems altogether: problems with MORNING cortisol not being high enough. Yes, not high enough. Lowering it would make health worse for these people. Yup, this problem does really exist for some people. No, everybody doesn’t need to “lower their cortisol”; some folks certainly might, but some need to do quite the opposite.

All this is very true and apologies if this wasn’t clear. There is no one-size fits all for everyone, not everyone has all the low serotonin symptoms and many folks have low cortisol at various times of the day.
Keep in mind these blogs are add-ons to what I cover in my book so if you are new to the amino acids (and other anxiety nutrition solutions like gluten/sugar/caffeine removal, blood sugar control, gut health, pyroluria etc) my book “The Antianxiety Food Solution” is a great place to start.

Hi Trudy, I’ve been following you for awhile and love your deep knowledge. I appreciate your sharing and doing so much work for so many of us. My question is, if 5htp can cause cortisol elevation, could Tryptophan also cause cortisol elevation? Isn’t 5-HTP a precursor to serotonin, and so is tryptophan? Is there some mechanism or something that makes 5HTP raise the cortisol, but not the tryptophan on the way to the serotonin?
If I still feel tired and wired on the tryptophan, even without the 5HTP, but do seem to benefit moodwise (so I’d like to continue taking the tryptophan), would I try only taking tryptophan in the day, but stop at a certain time of day to avoid any bumping of cortisol?
Thank you so much.
Jan
It’s possible but I have yet to see it happen clinically and there is no research to support this. It’s always a good idea to shift timing of amino acids so as to find the best benefits. If wired-tired symptoms continue we do look for high cortisol and low GABA.

Is vitamin b a good idea in the morning when taking 5HTP at night? Thanks
I typically have my clients use a B complex in the morning so as not to affect sleep
I have bad insomnia and have started taking GABA and tryptophan which help a little but I still only get 2-3 hours of sleep due mostly to anxiety I think. In the last 10 days it has been really bad and I wake up usually after 2 hours, mostly because I have to urinate….after that, I can’t get back to sleep, despite deep breathing and meditation. The last week I have tried 5 http and it’s been way worse. I guess I’m one of the unlucky ones who get that “wired/ tired buzz.
Do you have any suggestions? I’m really not feeling very well.
