5-Hydroxytryptophan, or 5-HTP, is an amino acid naturally produced in the body from the essential amino acid L-tryptophan. As a precursor to serotonin, a neurotransmitter involved in mood, sleep, and appetite regulation, 5-HTP has garnered significant interest for its potential therapeutic applications.

First isolated from the seeds of the African plant Griffonia simplicifolia in the 1960s, 5-HTP has since been studied for its effects on depression, anxiety, sleep disorders, and other conditions related to serotonin imbalance[1]. As a nootropic, 5-HTP is often used to support mood, emotional well-being, and stress resilience.

Benefits of 5-HTP

Mood Enhancement and Depression

One of the primary reasons people turn to 5-HTP is for its potential mood-boosting effects. As a serotonin precursor, 5-HTP may help alleviate symptoms of depression by increasing serotonin levels in the brain. While research is mixed, some studies suggest 5-HTP may be as effective as certain antidepressants, with fewer side effects[2].

Appetite Suppression and Weight Loss

5-HTP may also support weight loss efforts by reducing appetite and increasing feelings of fullness. In one study, overweight women who took 5-HTP consumed fewer calories and experienced greater satiety compared to a placebo group[3].

Fibromyalgia Symptom Relief

Fibromyalgia, a condition characterized by widespread pain and fatigue, has been linked to low serotonin levels. Some research suggests 5-HTP may help alleviate fibromyalgia symptoms, including pain, morning stiffness, and sleep disturbances[4].

Migraine Prevention

5-HTP has shown promise as a natural migraine preventative. Several studies have found that daily supplementation with 5-HTP may reduce the frequency, intensity, and duration of migraines in both adults and children[5][6][7].

Sleep Improvement

As a precursor to both serotonin and melatonin, 5-HTP may positively influence sleep quality and duration. Animal studies suggest 5-HTP can reduce sleep latency and increase REM sleep[8]. Learn More: Best Nootropics for Sleep

How 5-HTP Works in the Brain

To understand how 5-HTP influences brain function, let’s take a closer look at its role in the serotonin synthesis pathway:

  • L-Tryptophan, an essential amino acid obtained through diet, is converted into 5-HTP by the enzyme tryptophan hydroxylase.
  • 5-HTP is then converted into serotonin by the enzyme aromatic L-amino acid decarboxylase (AAAD).
  • Unlike L-tryptophan, 5-HTP can cross the blood-brain barrier, allowing for more direct serotonin synthesis in the brain[9].

Once synthesized, serotonin interacts with various receptor subtypes to influence mood, cognition, sleep, appetite, and pain perception. Learn More: Serotonin

It’s important to note that while 5-HTP can increase serotonin production, it may also influence other neurotransmitters, such as dopamine. Maintaining a balance between these neurotransmitters is crucial for optimal brain function. Learn More: Dopamine

5-HTP Dosage and Usage

The optimal 5-HTP dosage varies depending on the specific condition and individual factors. Here’s a general overview of common dosage ranges:

ConditionDosage RangeDuration
Depression150-300 mg daily2-6 weeks
Fibromyalgia100 mg 3-4 times daily2+ weeks
Migraines400-600 mg daily2-3 months
Weight Loss250-300 mg 30 min before meals2-12 weeks
Sleep100-300 mg before bedAs needed

When starting 5-HTP, it’s best to begin with the lowest effective dose and gradually increase as needed and tolerated. Some people may benefit from cycling 5-HTP, taking breaks every few weeks to prevent tolerance and maintain effectiveness.

5-HTP Side Effects and Precautions

While 5-HTP is generally well-tolerated, some people may experience side effects, including:

  • Nausea
  • Diarrhea
  • Stomach discomfort
  • Headache
  • Dizziness

More serious side effects, such as serotonin syndrome, can occur when 5-HTP is combined with certain medications that also increase serotonin, such as SSRIs, MAOIs, or migraine drugs like triptans. Symptoms of serotonin syndrome may include agitation, confusion, rapid heart rate, high blood pressure, and muscle rigidity. If you suspect serotonin syndrome, seek immediate medical attention.

To minimize the risk of interactions and adverse effects, always consult with a healthcare provider before starting 5-HTP, especially if you have a pre-existing medical condition or are taking medications.

5-HTP Discussions on Reddit

The nootropic community on Reddit offers valuable insights and personal experiences with 5-HTP. Here are some notable discussions:

Experiences with 5-HTP for Mood and Sleep

Many Reddit users report positive experiences with 5-HTP for improving mood and sleep quality. However, individual responses can vary:

I wouldn’t even notice effects from that dosage. I take 8500 mcg L methylfolate for dopamine production and 200 mg time release 5-htp for serotonin usually with my lunch. I can say this combination has greatly increased the quality of my life. Spells of depression, anxiety, and anhedonia are MUCH less prevalent.

5-HTP and Neurotransmitter Balance

Some users caution against the long-term use of 5-HTP, citing concerns about potential dopamine depletion:

You want to feel good? Increase dopamine, decrease serotonin. 5-HTP fucked me up back when I didn’t know better and I listened to nootheads on this sub giving themselves serotonin syndrome because they’ve been fed lies about serotonin being good for mental health.

u/wickedheat in discussion “5-HTP gives me depression but why?”

To maintain neurotransmitter balance, some recommend combining 5-HTP with dopamine precursors like L-tyrosine. Learn More: NALT

High-Dose 5-HTP Safety Concerns

Opinions on the safety of high-dose 5-HTP vary, with some users reporting tolerance with doses up to 600 mg daily:

I’ve taken 400-600mg of 5HTP for years now. I’ve been a-okay. There are stretches of time where it’s pretty clear it’s driven my norepinephrine levels down, but I manage it pretty easy by reducing 5HTP intake and introducing a stimulant like pseudoephedrine or atomoxetine for a bit to bring balance back.

However, it’s crucial to approach high doses cautiously and only under the guidance of a healthcare professional. Thorough personal research and careful monitoring of individual response are essential when experimenting with any nootropic.

Where to Buy 5-HTP

When shopping for 5-HTP supplements, prioritize quality and safety by considering the following factors:

  • Look for reputable brands that adhere to Good Manufacturing Practices (GMP) and undergo third-party testing for purity and potency.
  • Choose products with minimal fillers or additives, focusing on pure 5-HTP or synergistic combinations with vitamins like B6 and B12.
  • Opt for natural sources like
