Six weeks in and the shift in my general mood is genuinely noticeable. There was a flatness to most days that I hadn't fully registered until it started to lift. I feel more like myself. Really happy with this.

Mood
Direct serotonin support from 5-HTP. Clinically researched for mood elevation, anxiety reduction, and improved sleep — works within the central nervous system where most mood supplements don't reach.

- Elevates brain serotonin — 5-HTP crosses the blood-brain barrier and converts to serotonin within the CNS
- Reduces anxiety — higher serotonin tone quietens amygdala reactivity and lowers the background stress response
- Improves sleep — serotonin is the direct precursor to melatonin, supporting sleep onset and deep sleep architecture

The Experience
What You'll Feel
Hours 1–4
Serotonin Loading
5-HTP begins converting to serotonin within the brain. No dramatic shift yet — the nervous system is adapting to higher, more consistent serotonin availability with each dose.
Days 5–10
Mood Stabilisation
early serotonin normalisation begins. Many notice improved emotional resilience — less reactivity to daily stressors and a slightly more even emotional baseline throughout the day.
Weeks 2–3
Sleep Improvement
serotonin is the direct precursor to melatonin. Sleep onset becomes easier and slow-wave deep sleep more consistent — you may wake feeling more genuinely rested.
Week 3
Anxiety Softens
sustained serotonin support reduces the amygdala's reactivity to stressors. Social situations feel more manageable. The background hum of anxiety begins to quieten noticeably.
Week 4
Emotional Shift
mood is more consistently positive. The low-grade emotional heaviness that felt normal starts to lift. Energy and motivation improve as serotonin's broader neurological effects accumulate.
Weeks 5–6
Full Support
consistent mood, reduced anxiety, better sleep, and reduced carbohydrate cravings are all established. The compound effect of steady serotonin is now operating across every system it influences.
Month 2+
Your New Baseline
mood, sleep, anxiety, and appetite regulation are all operating with full serotonin support. What once felt like good days is now simply how you feel — this is your new emotional baseline.
The Formula
Why Our Mood
Most mood supplements work indirectly — adaptogens, herbs, stress modulators. Mood works at the source. 5-HTP is a direct serotonin precursor that crosses the blood-brain barrier independently, converting to serotonin within the CNS without competing with other amino acids for transport.
The 200mg dose sits at the upper end of the range used in peer-reviewed clinical trials. Calcium Carbonate supports the synaptic release step — without it, serotonin can't be released into the synapse regardless of how much is synthesised. Two ingredients, one complete pathway.
The Science
Evidence-Based Formulation
5-HTP is one of the most studied natural mood compounds in the world — a direct serotonin precursor with decades of peer-reviewed research supporting its use for mood, anxiety, sleep, and appetite regulation.
01
5-HTP significantly reduces depression scores — comparable to prescription antidepressants in clinical trials
Double-blind trials comparing 5-HTP to standard antidepressants found equivalent reductions in depression scores with a favourable tolerability profile. 5-HTP bypasses the tryptophan hydroxylase step to convert directly to serotonin — producing faster, more predictable serotonin elevation than dietary tryptophan.

5-HTP Inhibits Anxiety-Driven Panic Responses — Double-Blind Placebo-Controlled Study
A double-blind RCT found 5-HTP supplementation significantly reduced anxiety scores over 8 weeks versus placebo. The mechanism involves serotonergic modulation of the amygdala — higher serotonin tone reduces the amygdala's sensitivity to stressors, producing a calmer, less reactive baseline.

5-HTP improves sleep quality via the serotonin-to-melatonin conversion pathway
Serotonin is the direct precursor to melatonin — the hormone governing sleep onset and architecture. 5-HTP increases central serotonin availability, supporting melatonin synthesis in the pineal gland. Clinical studies show significant improvements in sleep onset time, total sleep duration, and slow-wave deep sleep quality.

5-HTP reduces caloric intake and carbohydrate cravings via serotonergic appetite regulation
A double-blind, placebo-controlled trial found 5-HTP significantly reduced daily caloric intake — particularly from carbohydrates — without voluntary dietary restriction. Serotonin is a key regulator of satiety in the hypothalamus, and elevated serotonin tone reduces the drive to seek out carbohydrate-dense foods.

5-Hydroxytryptophan: A Clinically-Effective Serotonin Precursor from Griffonia simplicifolia
Griffonia simplicifolia seeds contain 5-HTP at concentrations up to 20% dry weight — the highest of any plant source. Unlike tryptophan, 5-HTP crosses the blood-brain barrier independently with near-complete CNS uptake, without competing with other amino acids. Standardised seed extract ensures consistent potency.

Calcium is essential for synaptic neurotransmitter release and neurological signalling
Calcium ions trigger neurotransmitter vesicle fusion at synaptic terminals — without adequate calcium, serotonin cannot be released regardless of synthesis levels. Research links calcium deficiency to mood disturbance and anxiety. The 328mg per serving contributes 25% of daily intake, directly supporting serotonin signalling.

How to Take It
01
2 Capsules Daily
Take 2 capsules daily. Taking with a small meal reduces the chance of mild nausea that some individuals notice on an empty stomach.
02
Evening is Optimal
Taking 30–45 minutes before bed aligns with the serotonin-to-melatonin conversion pathway — supporting both sleep quality and next-day mood baseline.
03
Allow 3–4 Weeks
5-HTP works through accumulation. Give your serotonin system 3–4 weeks to recalibrate to consistently higher levels before assessing the full effect.

Anxiety has been a background noise for years. Within about three weeks of starting this the volume has turned down noticeably — still there but much more manageable. The 5-HTP mechanism makes complete sense.
I take it an hour before bed and sleep has improved significantly — falling asleep faster, waking up more rested. The serotonin converting to melatonin pathway is real and you feel it working.
Good product. I'd say it takes three to four weeks before anything is clearly noticeable — if I hadn't committed to giving it time I might have stopped too early. The mood improvement is real once it builds.
200mg is the right dose — the 50mg products I tried before did nothing. This one works. Mood is better, sleep is better, and emotional reactivity is noticeably lower. I feel more stable overall.
The evening cravings have reduced alongside the mood improvement — I wasn't expecting that. Less snacking, fewer sweet cravings, more even moods. The serotonin effect on appetite is apparently real.
My doctor mentioned 5-HTP as something to consider before a prescription route. A month in and I'm genuinely glad I tried this first. Mood and sleep both meaningfully better.
Consistency is what makes this work — you can't take it occasionally and expect results. Four months in on subscription and mood is the most stable it's been in years. Worth committing to.
