Lauren shared her struggle with sugar cravings that started after chemotherapy, asking her question on a recent tryptophan/DPA cravings blog post:
If I try the tryptophan or the 5-HTP and one or the other works, how long will I need to take them for the sugar cravings to stop?
Back in 2021 I had been off sugar for 2 years and it was easy to get off by slowing eliminating sugar. The last elimination was from my coffee and then it was easy to stay away from sugar.
I had chemotherapy for 6 months in 2022. I have not been able to get off sugar since then. After chemo ended, I had the cravings and don’t know how to end the cravings.
Any advice from you would be appreciated.
The good news is that if you have cravings that are caused by low serotonin and you find your ideal dose of tryptophan or 5-HTP, you will notice reduced sugar cravings immediately and they will be further reduced with consistent use, typically a few times a day.
The key is to figure out if your cravings are caused by low serotonin and then it’s a matter of doing a trial of either tryptophan or 5-HTP (if you get results and other low serotonin symptoms improve it’s a clue you’re on track). And then you need to figure out the ideal dose for your unique needs. I share more about all this below and additional information about other types of cravings caused by neurotransmitter imbalances (and the respective amino acids that help).
Since her cravings struggles started after chemotherapy I also discuss possible impacts on neurotransmitters and also candida (sugar cravings are very common with the candida). Read on for my response to the above question from Lauren.
Sugar cravings caused by low serotonin: tryptophan or 5-HTP may offer immediate results
As I mentioned above you will notice reduced sugar cravings immediately with either tryptophan or 5-HTP if your cravings are caused by low serotonin. A big clue with low serotonin-type sugar or carb cravings is that they are more intense in the late afternoon and evening.
A good place to start (as always) is with the symptoms questionnaire. If there are other low serotonin symptoms such as feeling more anxious, worried, fearful with a low mood and irritability etc, that further confirms it’s worth doing a trial.
Some folks do better with one than the other but I have clients start with tryptophan and then switch to 5-HTP if their results are not as expected. In both instances we open the capsule or use powders or a chewable to get instant feedback on the benefits. So in that first session Lauren should be able to say “wow my cravings have reduced from 10/10 to 5/10” within 5-10 minutes. She may also report she feels more optimistic and less worried.
It is possible that her cravings are not caused by low serotonin or that they are a combination of a number of factors.
Sugar cravings caused by other neurotransmitter imbalances, and other amino acids to the rescue
We also look at sugar cravings caused by low GABA (stress eating because of physical tension), low endorphins (comfort eating or emotional eating), low dopamine (eating for an energy boost or improved focus) and low blood sugar (eating due to crankiness and irritability).
Lauren would know if any of the above may be factors based on her scores on the symptoms questionnaire i.e. scores for cravings and other symptoms. This offers further clarification:
- If you eat sugar or carbs to feel happy (and especially from late afternoon into the evening) then your sugar cravings are likely due to low serotonin, and tryptophan (or 5-HTP) stops the cravings and boosts mood and reduces anxiety
- If you stress-eat your sugar cravings are likely due to low GABA, and GABA will stop the stress-eating and calm you down
- If you are a comfort-eater then it’s likely due to low endorphins and DPA will stop that feeling of “I deserve-it” kind of reward-eating or comfort-eating and also give you a hug-like mood boost
- If you eat sugar for an energy boost or to give your focus then it’s likely due to low catecholamines and tyrosine will stop those cravings and give you a mood and energy boost, and help with mental clarity
- If you have to eat sugar when you haven’t eaten in awhile it’s likely low blood sugar and glutamine on the tongue stops the sugar desire almost immediately and also helps with the low blood sugar symptoms of shakiness and irritability
As you can see there is an amino acid for each of these imbalances and it’s a matter of doing a similar trial for each one. With the correct dose, Lauren can expect quick results too, provided she finds the ideal dose for her needs.
This is the blog post Lauren posted her question on: Tryptophan and DPA (d-phenylalanine) for cravings and sleep issues (and a concern about 5-HTP and nightmares).
It’s one of many posts on the site about amino acids and sugar cravings so I encourage you to use the search feature of the blog.
Chemotherapy: impacts on serotonin and dopamine
Because chemotherapy has an impact on serotonin and dopamine, this may be where Lauren needs to start when considering which amino acids to trial. Here is some additional information on “chemobrain” or chemotherapy-induced cognitive impairment:
… a medical complication of cancer treatment that is characterized by a general decline in cognition affecting visual and verbal memory, attention, complex problem solving skills, and motor function. It is estimated that one-third of patients who undergo chemotherapy treatment will experience cognitive impairment.
Alterations in the release and uptake of dopamine and serotonin, central nervous system neurotransmitters that play important roles in cognition, could potentially contribute to impaired intellectual performance in those impacted by chemobrain.
And this may offer an explanation as to why she hasn’t been able to quit sugar since chemotherapy.
Chemotherapy, candida albicans and sugar cravings
If none of the above approaches reduce her cravings or if they do help to some extent but are not quite enough, we have to keep looking for root causes.
A big clue is that Lauren had been able to quit sugar using willpower in the past but has struggled since chemotherapy. It’s important to consider the role this may be playing. In cancer patients who have gone through chemotherapy there is increased susceptibility to Candida albicans, “a fungal commensal and a major colonizer of the human skin, as well as of the gastrointestinal and genitourinary tracts.” This is reported to be caused primarily by “chemotherapy-induced depression of innate immune cells and weakened epithelial barriers, which are the body’s first-line defenses against fungal infections.”
Sugar cravings are very common with candida and in some cases can be so severe that no amino acids will work until the candida is addressed. Interestingly, in one candida study, short exposure to serotonin resulted in antifungal activity so it’s possible that tryptophan or 5-HTP helps.
I don’t have my candida symptoms questionnaire on the blog but you can find a mini version on page 93 of my book, The Antianxiety Food Solution and additional information and my dietary/nutrient protocol in chapter 5 of my book.
The full candida questionnaire can be found in William G. Crook’s excellent book, The Yeast Connection and Women’s Health (my Amazon link).
Additional resources when you are new to using amino acids as supplements
As always, I use the symptoms questionnaire to figure out if low low serotonin or other neurotransmitter imbalances may be an issue.
If you suspect low levels of any of the neurotransmitters and do not yet have my book, The Antianxiety Food Solution – How the Foods You Eat Can Help You Calm Your Anxious Mind, Improve Your Mood, and End Cravings, I highly recommend getting it and reading it before jumping in and using amino acids on your own so you are knowledgeable. And be sure to share it with the practitioner/health team you or your loved one is working with.
There is an entire chapter on the amino acids and they are discussed throughout the book in the sections on gut health, gluten, blood sugar control (this is covered in an entire chapter too), sugar cravings, anxiety and mood issues.
The book doesn’t include product names (per the publisher’s request) so this blog, The Antianxiety Food Solution Amino Acid and Pyroluria Supplements, lists the amino acids that I use with my individual clients and those in my group programs.
If, after reading this blog and my book, you don’t feel comfortable figuring things out on your own (i.e. doing the symptoms questionnaire and respective amino acids trials), a good place to get help is the GABA QuickStart Program (if you have low GABA symptoms too). This is a paid online/virtual group program where you get my guidance and community support.
If you are a practitioner, join us in The Balancing Neurotransmitters: the Fundamentals program. This is also a paid online/virtual program with an opportunity to interact with me and other practitioners who are also using the amino acids.
Wrapping up and your feedback
I appreciate Lauren for posting her question on the blog so I can share and we all can learn.
Now I’d love to hear from you – does any of this resonate with you? If yes, what approach helped reduce your sugar cravings after chemotherapy?
If you’re a practitioner have you seen these approaches work well with your clients/patients?
Feel free to share and ask your questions below.

Thank you Trudy for all your knowledge that you share.
I am interested in the Amazing Amino Acid course, but have time restraints at the moment. When I buy it do I have it for life? Can I take my time to work through the course at my convenience or do I have to complete it in 8 weeks and then the information is withdrawn?
Thank you

Right now access is indefinite so you’ll have time to work through it at your convenience. I can share that for most folks once they get started they keep going because the results they experience are so good.
Lisa Reed says
I just got done with 4 months worth of chemo. After each treatment I would go into crying spells which turned into anxiety and then depression. My doctors wanted me to take Cymbalta but I didn’t want to go that route. I have sporadically used a small dose of Xanax to come down which helped so much. Now that I’ve had my last treatment I’m still having the emotional breakdowns. Are these feelings due to gut issues? My doctor says it’s a combo of chemo, steroids and loss of my ovaries. Can you suggest what I should use? I’ve used Gaba and L-tryptophan in the past but not regularly. Thanks

I’m sorry to hear you’re struggling. I can’t make recommendations via the blog but can share that I have clients do the symptoms questionnaire https://www.everywomanover29.com/blog/amino-acids-mood-questionnaire-from-the-antianxiety-food-solution/ and we do trials (one at a time) based on their symptoms. With crying spells and emotional breakdowns we often start with a trial of DPA for endorphin support. When someone shares that Xanax has helped that indicates that GABA may help too and we trial that too. If it’s helped in the past that’s a clue too.
Candida can also trigger mood issues so we explore and address this too if need be. Keep in mind chemotherapy also disrupts the microbiome (https://onlinelibrary.wiley.com/doi/full/10.1111/apt.13302) so addressing gut health and leaky gut is important.
If you’re new to the amino acids my book is a good place to start. More here https://www.everywomanover29.com/blog/the-antianxiety-food-solution-by-trudy-scott/
Finding a functional medicine practitioner for hormone support is key too.
