What the research says about this formula's ingredients
Educational summaries of published research on L-theanine and magnesium (including magnesium bisglycinate), including honest null and mixed findings - these are ingredient-level summaries, not claims about this finished product. Orange Naturals L-Theanine with Magnesium's own claim is the authorized use under NPN 80077089: helping to temporarily promote relaxation.
Four weeks of 200 mg/day L-Theanine improved anxiety-trait and sleep-quality scores
In a randomised, placebo-controlled, double-blind crossover trial of 30 healthy adults, four weeks of 200 mg/day L-Theanine reduced Self-rating Depression Scale, State-Trait Anxiety Inventory-trait, and Pittsburgh Sleep Quality Index scores compared with placebo, alongside improvements in verbal fluency and executive function.
Human RCTA systematic review found 200-400 mg/day may help manage stress and anxiety
A systematic review of 9 human randomised controlled trials concluded that supplementation with 200-400 mg/day of L-Theanine may assist in reducing stress and anxiety in people exposed to stressful conditions, while noting that longer-term, larger studies are still needed.
Systematic reviewL-Theanine and L-Tyrosine were studied together against a virtual-reality stress drill
In a randomized trial of 80 young adults, ingestion of L-theanine and L-tyrosine was compared against placebo for markers of stress and cognitive performance during a mental stress challenge combining a Stroop task and a virtual-reality active-shooter training drill, building on earlier findings that each amino acid can reduce salivary stress biomarkers on its own.
Human RCTCombining L-Theanine with caffeine lowered anxiety while preserving performance in elite athletes
In a double-blind, placebo-controlled crossover trial of 12 elite wrestlers, caffeine alone increased anxiety and overstimulation, but a caffeine plus L-Theanine combination helped mitigate these side effects while supporting physical and cognitive performance - illustrating L-theanine's calm-without-sedation profile.
Human RCTA systematic review found L-Theanine reduced symptoms across several psychiatric conditions
A systematic review of randomized controlled trials found that L-Theanine, used adjunctively alongside antidepressants, antipsychotics and other psychopharmacological drugs, showed potential for enhancing symptomatic outcomes without the sedation associated with many calming medications.
Systematic reviewTheanine-rich matcha reduced stress in both animal and human studies, but the caffeine-to-theanine ratio mattered
Reviewing animal and clinical experiments, theanine (the major amino acid in green tea) showed a stress-reducing effect, but the effect was only observed in matcha when the ratio of caffeine and EGCG to theanine and arginine stayed below a certain threshold - a reminder that formulation balance affects whether a calming effect without overstimulation is achieved.
Animal + human studyA meta-analysis of 19 trials found L-Theanine significantly improved sleep quality
A systematic review and meta-analysis of 19 randomized controlled trials (897 participants) found L-Theanine significantly improved subjective sleep onset latency, subjective daytime dysfunction, and overall subjective sleep quality scores compared with placebo.
Meta-analysisA systematic review of dietary supplementation trials found L-Theanine can help support sleep
A systematic review of dietary supplementation trials concluded that L-Theanine's calming effects - aiding relaxation without sedation or impaired cognitive function - extend to supporting sleep in humans, building on earlier pre-clinical findings.
Systematic reviewAn honest null finding: theanine-rich matcha did not change objective sleep measures on EEG, though subjective well-being improved
In a placebo-controlled, double-blind trial, four weeks of daily matcha (containing 50.3 mg theanine) produced no significant difference from control in total sleep time, sleep latency, or sleep efficiency measured by electroencephalography - though a subjective wellbeing questionnaire showed a trend toward increased satisfaction, an honest split between objective and subjective outcomes.
Human RCTAn honest 2025 review: the mechanism is plausible, but the strongest human evidence is still limited
A 2025 review of L-Theanine's chemistry and biology confirms it is well absorbed and crosses the blood-brain barrier, and that some studies link it to increased alpha brain waves associated with relaxation - but the authors caution that rigorous human clinical trials remain limited and urge care in how strongly benefits are claimed, concluding 'the science does not yet match the hype.'
ReviewA safety review found L-Theanine reliable even at higher dietary intakes
A review of L-Theanine's metabolism, health effects and safety concluded that results of acute and chronic toxicity testing indicate L-Theanine is generally reliable, even when consumed in excess of typical dietary amounts.
Safety reviewAn honest null finding: a formulated nutritional blend including theanine showed minimal effect on next-morning athletic performance
In a randomized, placebo-controlled crossover trial of 17 trained adult males, a pre-sleep nutritional blend containing theanine (alongside carbohydrate, whey, tryptophan and 5'AMP) showed only minimal influence on objective and subjective sleep, next-morning physical performance, cognitive function or postural sway compared with placebo - an honest reminder that not every calming-ingredient blend produces a measurable next-day benefit.
Human RCTA systematic review found magnesium suggestive of a beneficial effect on subjective anxiety in vulnerable groups
A systematic review of 18 studies found evidence suggestive of a beneficial effect of magnesium supplementation on subjective anxiety in samples with an existing vulnerability to anxiety (mildly anxious, premenstrual, and hypertensive groups), while noting the overall evidence quality was poor and well-designed trials are still needed.
Systematic reviewA review linked magnesium status to depressive and anxiety symptoms across mental disorders
A systematic review of 32 articles on magnesium in mental disorders found that reduced plasma magnesium correlated with depressive symptoms in multiple studies, and that magnesium supplementation was associated with improved outcomes in some anxiety and depression studies, while calling for dedicated clinical trials to confirm efficacy.
Systematic reviewA systematic review found magnesium generally improved anxiety and sleep outcomes with minimal side effects
A systematic review of 15 interventional trials found the majority demonstrated improvement in at least one sleep- or anxiety-related outcome with supplemental magnesium, with minimal side effects reported, though the authors noted heterogeneity across studies and called for larger, better-designed trials.
Systematic review250 mg of magnesium bisglycinate modestly reduced insomnia severity in a placebo-controlled trial
In a randomized, double-blind, placebo-controlled trial of 155 adults reporting poor sleep, four weeks of 250 mg elemental magnesium as magnesium bisglycinate produced a significantly greater reduction in Insomnia Severity Index scores than placebo, with a modest effect size and larger benefits seen in those with lower baseline dietary magnesium intake.
Human RCTA human trial found chelated magnesium diglycinate better absorbed than magnesium oxide
In a double-blind, randomized crossover trial in patients with ileal resection, isotope-labelled magnesium diglycinate (chelate) showed substantially greater absorption than magnesium oxide in those with the most impaired magnesium absorption, and was better tolerated by all patients, supporting absorption in part as an intact dipeptide.
Human RCTA mouse study found tissue magnesium uptake varied across different organic magnesium compounds, including glycinate
In a mouse study comparing four organic magnesium compounds - citrate, malate, acetyl taurate and glycinate - at three doses, tissue magnesium uptake patterns differed by compound: magnesium acetyl taurate consistently raised brain magnesium levels, while magnesium citrate raised muscle and brain magnesium in a dose-independent manner; the authors note further research is needed on long-term administration.
Animal studyA magnesium plus L-Theanine (green tea) combination reduced chronic stress scores in a placebo-controlled trial
In a randomized, placebo-controlled trial of 100 chronically stressed adults, 28 days of a combination supplement containing magnesium, B vitamins, rhodiola and green tea/L-Theanine significantly reduced DASS-42 stress scores compared with placebo, with improvements in sleep-related quality-of-life parameters also observed.
Human RCTA 2026 review positions a magnesium-L-Theanine complex as a multi-target relaxation strategy
A 2026 review of a novel magnesium-L-Theanine (MgT) complex summarizes converging human evidence for anxiolytic, antidepressant and sleep-promoting benefits from magnesium and L-Theanine supplementation, alongside preclinical findings on stress-related gut and metabolic pathways, supporting the translational rationale for combining the two ingredients.
ReviewA nutraceutical combination including L-Theanine and magnesium reduced OCD symptom severity in a pilot study
In a 20-week open-label pilot study of 28 people with treatment-resistant OCD, a combination of nutraceuticals including L-Theanine, magnesium, zinc and N-acetyl cysteine produced a significant reduction in Yale-Brown Obsessive-Compulsive Scale scores over time, with the authors noting the finding needs confirmation in a placebo-controlled trial.
Human studyL-Theanine plus vitamin B6 reduced tics and anxiety in children with Tourette syndrome
In a pilot trial of 34 children with Tourette syndrome or chronic tic disorder and co-occurring anxiety symptoms, supplementation with L-Theanine and vitamin B6 was significantly more effective than psychoeducation alone at reducing tic severity, with reductions in anxiety symptoms also observed.
Human RCTA chamomile and L-theanine beverage reduced menstrual pain and improved mood and sleep in young women
In a randomized, double-blind, placebo-controlled trial of 30 young women with primary dysmenorrhea, a chamomile and L-theanine beverage taken around menstruation significantly reduced pain intensity and several menstrual symptoms compared with a chamomile-only control, alongside improvements in mood and daytime sleep dysfunction.
Human RCTA walnut peptide and theanine combination improved chronic stress-induced sleep disruption across three species
A translational study combining zebrafish screening, a chronic-stress mouse model, and an eight-week randomized placebo-controlled human trial found a walnut peptide and theanine combination restored slow-wave sleep architecture, lowered stress-hormone signalling, and improved subjective sleep quality scores in adults with sleep disturbances.
