Repose Ease · the ingredients

Ten ingredients. Three pathways.
Every dose trial-aligned.

Every gram in Repose Ease is dosed to match the clinical trial it points back to — not the FDA minimum, not the cheapest fill. Here is each ingredient, what it does, and the published research behind it.

L-Theanine
L-theanine · green tea leaf
01 · GABA / alpha-wave support

L-Theanine.

A free amino acid found almost exclusively in tea leaves.
400 mg per serving

L-theanine crosses the blood-brain barrier and increases alpha-wave activity — the EEG signature of relaxed, alert wakefulness. It also supports GABA function (the nervous system's primary calming neurotransmitter) without sedating. Replicated trials at 200–400 mg/day show acute anxiety reduction without sedation.

The science
Hidese S, et al. Nutrients, 2019.
200 mg/day of L-theanine for 4 weeks reduced stress-related symptoms (sleep disturbance, anxiety, depression) and improved verbal fluency and executive function in healthy adults.

KSM-66 Ashwagandha
KSM-66® ashwagandha root
02 · HPA-axis modulation

KSM-66® Ashwagandha.

Withania somnifera — standardised full-spectrum root extract.
600 mg per serving

Ashwagandha lowers serum cortisol — the stress hormone the adrenals release in response to perceived threat. KSM-66 is the specific full-spectrum root extract used in the high-quality clinical trials. Not generic ashwagandha. The exact extract the studies used, at the 600 mg dose Chandrasekhar replicated.

The science
Chandrasekhar K, et al. Indian Journal of Psychological Medicine, 2012.
64 adults with chronic stress received 300 mg of KSM-66 twice daily for 60 days. Serum cortisol dropped 27.9%, and scores on PSS, GHQ-28 and DASS stress scales improved significantly versus placebo.

Affron Saffron
Affron® saffron stigmas
03 · Serotonergic mood

Affron® Saffron.

Crocus sativus stigma extract, standardised to Lepticrosalides 3.5%.
30 mg per serving

Saffron's active compounds — crocin and safranal — act on both serotonin and dopamine pathways. Affron is the patented saffron extract studied directly in randomised trials at 28–30 mg, with measurable improvement in mood, anxiety, and stress-related symptoms. Meta-analyses show effect sizes comparable to first-line SSRIs in mild-to-moderate cases.

The science
Lopresti AL, et al. Journal of Affective Disorders, 2018.
14 mg twice daily of Affron for 8 weeks produced significant improvements in youth-reported anxiety and depressive symptoms versus placebo.

Magnesium Glycinate
Magnesium glycinate · chelate
04 · NMDA modulation

Magnesium Glycinate.

A highly bioavailable chelated form of elemental magnesium.
150 mg per serving

Magnesium is a cofactor in more than 300 enzymatic reactions, including GABA receptor function and NMDA receptor regulation — both of which influence the nervous system's stress response. We use the glycinate chelate because it absorbs cleanly and doesn't cause the GI symptoms that magnesium oxide and citrate often do.

The science
Boyle NB, Lawton C, Dye L. Nutrients, 2017.
Systematic review of 18 studies found suggestive evidence for a beneficial effect of magnesium on subjective anxiety in anxiety-vulnerable samples, with strongest signals at 150–450 mg/day.

Daily magnesium supplementation produced clinically significant improvements in depression and anxiety scores within two weeks, with effects independent of baseline magnesium status.

Glycine
Glycine · inhibitory amino acid
05 · Inhibitory neurotransmitter

Glycine.

A non-essential amino acid that doubles as an inhibitory neurotransmitter.
1,000 mg per serving

Glycine acts directly on inhibitory receptors in the brainstem and spinal cord. At 1 g it supports sleep-onset, reduces sympathetic arousal, and is particularly useful for anxious people who fall asleep easily but wake at 3am with a racing mind.

The science
Kawai N, et al. Neuropsychopharmacology, 2015.
Glycine administration before bed lowered core body temperature and improved subjective sleep quality, with effects mediated through NMDA receptors in the brain's circadian centre.

Inagawa K, et al. Sleep and Biological Rhythms, 2006.
3 g of glycine taken before bedtime significantly improved subjective sleep quality and reduced daytime fatigue in self-reported poor sleepers.

Lemon Balm
Melissa officinalis leaf
06 · GABA-ergic + parasympathetic

Lemon Balm.

Melissa officinalis — standardised leaf extract.
300 mg per serving

Lemon balm increases GABA availability in the brain by inhibiting the enzyme that breaks GABA down (GABA transaminase). In acute-stress studies it has reliably reduced laboratory-induced anxiety while improving cognitive performance — useful when staying calm and staying sharp need to happen at the same time.

The science
Kennedy DO, et al. Psychosomatic Medicine, 2004.
Acute lemon balm (300 mg or 600 mg) significantly reduced negative-mood effects of a laboratory stressor and improved calmness ratings versus placebo within 1–3 hours.

L-Lysine + L-Arginine
L-lysine + L-arginine
07 · Trait anxiety · HPA attenuation

L-Lysine + L-Arginine.

An essential and a conditionally-essential amino acid, paired.
500 mg + 500 mg per serving

A specific pairing studied by Smriga and Jezova for trait anxiety and HPA-axis attenuation in stressed adults. The combination reduces basal cortisol and lowers subjective trait-anxiety scores in people with chronically elevated stress, at the doses studied.

The science
Smriga M, et al. Biomedical Research, 2007.
L-lysine (2.64 g) plus L-arginine (2.64 g) reduced state and trait anxiety scores and lowered basal cortisol in a placebo-controlled crossover trial of healthy adults.

Vitamin B6
Pyridoxal-5-phosphate
08 · Cofactor for neurotransmitter synthesis

Vitamin B6.

Pyridoxal-5-phosphate — the bioactive form of B6.
25 mg per serving

B6 is the essential cofactor that converts amino acid precursors into serotonin and glutamate into GABA. Without enough of it, the rest of the formula can't fully do its work. A 2022 trial found that high-dose B6 alone significantly reduced self-reported anxiety in young adults.

The science
Field DT, et al. Human Psychopharmacology, 2022.
100 mg/day of B6 for one month significantly reduced self-reported anxiety and depression scores in young adults, with measurable effects on visual GABAergic processing.

Vitamin B12
Methylcobalamin crystal
09 · Methylation support

Vitamin B12.

Methylcobalamin — the activated, methylated form of B12.
500 mcg per serving

B12 is required for methylation — the biochemical process that produces SAM-e, the body's universal methyl donor and a precursor for serotonin, dopamine, and noradrenaline synthesis. We use methylcobalamin (not the cheaper cyanocobalamin) so people with MTHFR variants still absorb it cleanly.

Wald DS, et al. American Journal of Clinical Nutrition, 2014.

Zinc
Zinc glycinate
10 · Cofactor / receptor modulation

Zinc Glycinate.

A chelated form of elemental zinc bound to glycine.
15 mg per serving

Low zinc is repeatedly found in anxious populations. Zinc modulates the glutamate-NMDA system and supports serotonin synthesis as a cofactor. The glycinate chelate is well-absorbed and gentle on the gut.

The science
Sayyah M, et al. Progress in Neuro-Psychopharmacology & Biological Psychiatry, 2012.
In a randomized trial, zinc augmentation produced significantly greater anxiety-score reductions than SSRI alone over 8 weeks.
