Clinical References

The research behind every ingredient.

Every ingredient in CLARIA is backed by published, peer-reviewed research. We list every study so you can read it yourself.

CLARIA does not make medical claims. These references are provided so you can read the research yourself. The studies below are published, peer-reviewed research on the specific ingredients, forms, and doses used in the CLARIA formula. We have summarised each study in plain language — but we encourage you to read the originals.

600mg · KSM-66®

Ashwagandha KSM-66

Cortisol regulation · HPA axis modulation · Sleep quality

Double-blind RCT n = 64

Chandrasekhar, K., Kapoor, J., & Anishetty, S. (2012). A prospective, randomised double-blind, placebo-controlled study of safety and efficacy of a high-concentration full-spectrum extract of ashwagandha root in reducing stress and anxiety in adults. Indian Journal of Psychological Medicine, 34(3), 255–262.

A 60-day trial in 64 adults. The KSM-66 group (600mg daily) showed a 27.9% reduction in serum cortisol compared to placebo, alongside significant improvements in stress, anxiety, and overall wellbeing scores.

Double-blind RCT n = 150

Langade, D., Kanchi, S., Salve, J., Debnath, K., & Ambegaokar, D. (2019). Efficacy and safety of ashwagandha root extract in insomnia and anxiety: A double-blind, randomised, placebo-controlled study. Cureus, 11(9).

8-week trial in 150 adults with insomnia. KSM-66 at 600mg daily produced statistically significant improvements in sleep onset latency, total sleep time, sleep quality, and morning alertness versus placebo.

Double-blind RCT n = 60

Salve, J., Pate, S., Debnath, K., & Langade, D. (2019). Adaptogenic and anxiolytic effects of ashwagandha root extract in healthy adults: A double-blind, randomised, placebo-controlled clinical study. Cureus, 11(12).

Demonstrated KSM-66 at 240mg daily significantly reduced anxiety and cortisol in healthy adults — at a dose lower than CLARIA's formulation, confirming efficacy within our dosing range.

200mg

L-Theanine

Alpha brain wave induction · Stress response · Sleep quality

Controlled trial

Nobre, A.C., Rao, A., & Owen, G.N. (2008). L-Theanine, a natural constituent in tea, and its effect on mental state. Asia Pacific Journal of Clinical Nutrition, 17(S1), 167–168.

200mg L-Theanine significantly increased alpha brain wave activity within 40 minutes of ingestion — the relaxed, non-drowsy mental state that precedes natural sleep onset — without producing sedation.

Randomised controlled trial n = 30

Hidese, S., Ogawa, S., Ota, M., et al. (2019). Effects of L-Theanine administration on stress-related symptoms and cognitive functions in healthy adults: A randomised controlled trial. Nutrients, 11(10), 2362.

4-week trial at 200mg daily. L-Theanine significantly reduced sleep difficulty, anxiety, and stress-related symptoms compared to placebo in healthy adults.

300mg · Glycinate form

Magnesium Glycinate

GABA activation · Sleep onset · Cortisol modulation

Double-blind RCT n = 46

Abbasi, B., Kimiagar, M., Sadeghniiat, K., et al. (2012). The effect of magnesium supplementation on primary insomnia in elderly adults. Journal of Research in Medical Sciences, 17(12), 1161–1169.

Magnesium supplementation significantly improved sleep onset latency, sleep efficiency, sleep time, and early morning awakening, alongside measurable reductions in serum cortisol and increases in serum melatonin.

Systematic review 18 studies

Boyle, N.B., Lawton, C., & Dye, L. (2017). The effects of magnesium supplementation on subjective anxiety and stress — a systematic review. Nutrients, 9(5), 429.

Review of 18 studies concluding that magnesium supplementation shows consistent benefit for subjective anxiety in mildly anxious individuals and those under chronic stress.

Bioavailability study

Coudray, C., Rambeau, M., Feillet-Coudray, C., et al. (2005). Study of magnesium bioavailability from ten organic and inorganic Mg salts using a stable isotope approach. Magnesium Research, 18(4), 215–223.

Confirmed magnesium glycinate has significantly superior bioavailability compared to magnesium oxide — the form in most budget supplements, which showed approximately 4% absorption.

500mg · Montmorency variety

Tart Cherry Extract

Melatonin synthesis support · Sleep duration · Night waking

Crossover trial

Pigeon, W.R., Carr, M., Gorman, C., & Perlis, M.L. (2010). Effects of a tart cherry juice beverage on the sleep of older adults with insomnia: A pilot study. Journal of Medicinal Food, 13(3), 579–583.

Montmorency tart cherry significantly increased sleep time and sleep efficiency compared to placebo in adults with chronic insomnia, attributed to melatonin content and melatonin synthesis support.

Randomised controlled trial

Howatson, G., Bell, P.G., Tallent, J., et al. (2012). Effect of tart cherry juice (Prunus cerasus) on melatonin levels and enhanced sleep quality. European Journal of Nutrition, 51(8), 909–916.

Montmorency tart cherry consumption significantly elevated urinary melatonin levels and improved sleep duration and quality compared to placebo. This study used the Montmorency cultivar referenced in CLARIA's formulation.

300mg · Standardised extract

Lemon Balm Extract

GABA transaminase inhibition · Anxiety · Rumination

Pilot study n = 20

Cases, J., Ibarra, A., Feuillère, N., Roller, M., & Sukkar, S.G. (2011). Pilot trial of Melissa officinalis L. leaf extract in the treatment of volunteers suffering from mild-to-moderate anxiety disorders and sleep disturbances. Mediterranean Journal of Nutrition and Metabolism, 4(3), 211–218.

After 15 days at 300mg twice daily, 85% of participants reported improved sleep quality. Anxiety symptoms fell by 18% and insomnia by 42% versus baseline.

Controlled laboratory study

Kennedy, D.O., Little, W., & Scholey, A.B. (2004). Attenuation of laboratory-induced stress in humans after acute administration of Melissa officinalis. Psychosomatic Medicine, 66(4), 607–613.

A single dose of lemon balm extract significantly reduced stress and improved calmness in a controlled setting — providing mechanistic support for its effect on cortisol sensitivity and the stress response.

10mg · Pyridoxine HCl

Vitamin B6

Serotonin → melatonin conversion · GABA biosynthesis

Mechanistic study

Ebben, M., Lequerica, A., & Spielman, A. (2002). Effects of pyridoxine on dreaming: A preliminary study. Perceptual and Motor Skills, 94(1), 135–140.

Confirmed B6's cofactor role in the conversion of tryptophan to serotonin, and serotonin to melatonin — the biochemical basis for its inclusion in CLARIA's formula as the final link in the melatonin synthesis chain.

Mechanistic review

Dakshinamurti, K., Sharma, S.K., & Geiger, J.D. (2003). Neuroprotective actions of pyridoxine. Biochimica et Biophysica Acta, 1647(1–2), 225–229.

Documents B6's essential role in GABA biosynthesis — directly relevant to its inclusion alongside magnesium glycinate and lemon balm, all three of which support the GABAergic system through different mechanisms.

A note on reading this research

The studies listed here are published, peer-reviewed research available through PubMed, ResearchGate, and institutional databases. Some are large randomised controlled trials. Some are smaller pilots. We have tried to indicate the scale and type of each study so you can weigh the evidence appropriately.

Where we reference clinical research, we are not claiming that CLARIA replicates the conditions of any particular study. We are showing you the evidence base for each ingredient at the relevant dose and in the relevant form so that you can make an informed decision.

Supplements are not medicines. CLARIA is not a treatment for insomnia, anxiety, or any other medical condition. If you have a diagnosed sleep disorder or are under medical supervision, speak to your GP before use.

The research is provided because you have a right to see it.
