The Science Behind [day/night]
Real doses. Real research. Real results. Backed by what your body actually needs to feel a difference.
Most Supplements Fail. Here's Why.
Most supplements fail for one simple reason: pixie dosing.
'Pixie dosing' is when a brand puts a clinically meaningful ingredient into their formula, BUT at a tiny, sub-therapeutic dose. It looks impressive on the label. It does nothing in your body.
We built [day/night] to solve this. Every active ingredient in our blends is included at the full clinically studied dose, the amount actually shown in research to produce a measurable effect.
That's why one scoop of [day] or [night] can replace 20+ separate supplements: it's not just what's in it, it's how much.
Our Formulation Principles
Functional Dosing
Every active is included at the dose studied in peer-reviewed research. No pixie dosing. Ever.
Bioavailable Forms
Magnesium glycinate (not oxide). Methylated B vitamins (not synthetic). Chelated minerals.
Synergy Over Stack-Chasing
Ingredients selected to work together, not just to look impressive on the label.
Australian Made
Formulated and manufactured in Australia at a GMP-certified, TGA-compliant facility.
Third-Party Tested
Every batch independently tested for purity, potency, and contaminants. COAs available on request.

Research Library
A selection of peer-reviewed research supporting key ingredients in our formulas:
Effects of L-Theanine Administration on Stress-Related Symptoms and Cognitive Functions in Healthy Adults: A Randomized Controlled Trial — 200 mg/day for 4 weeks; improved verbal fluency, executive function, and reduced stress-related symptoms.
Effects of l-Theanine on Cognitive Function in Middle-Aged and Older Subjects: A Randomized Placebo-Controlled Study — 200 mg/day; reduced reaction time on attention tasks and improved working memory.
Magnesium Bisglycinate Supplementation in Healthy Adults Reporting Poor Sleep: A Randomized, Placebo-Controlled Trial — 250 mg elemental magnesium/day; significantly reduced insomnia severity scores vs. placebo at Week 4.
The Effect of Magnesium Supplementation on Primary Insomnia in Elderly: A Double-Blind Placebo-Controlled Clinical Trial — 500 mg/day for 8 weeks; improved sleep onset latency, sleep efficiency, and serum melatonin.
A Prospective, Randomized 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 — 300 mg twice daily (600 mg total); 27.9% reduction in serum cortisol vs. 7.9% in placebo group.
An Investigation into the Stress-Relieving and Pharmacological Actions of an Ashwagandha Extract: A Randomized, Double-Blind, Placebo-Controlled Study — 240 mg/day; significant reductions in cortisol, anxiety scores, and perceived stress.
Tyrosine Improves Cognitive Performance and Reduces Blood Pressure in Cadets After One Week of Combat Training — 2 g/day; improved memory and tracking task performance under sustained psychosocial and physical stress.
Tyrosine Improves Working Memory in a Multitasking Environment — 150 mg/kg; significantly enhanced accuracy on working memory tasks under high cognitive demand.
Antifatigue Effects of Coenzyme Q10 During Physical Fatigue — 100–300 mg/day for 8 days; 300 mg group showed significantly greater physical output and reduced fatigue vs. placebo.
Effectiveness of Coenzyme Q10 Supplementation for Reducing Fatigue: A Systematic Review and Meta-Analysis of Randomized Controlled Trials — Meta-analysis of 13 RCTs (n=1,126); CoQ10 showed statistically significant fatigue reduction, with greater benefit at higher doses.
The Effects of Glycine on Subjective Daytime Performance in Partially Sleep-Restricted Healthy Volunteers — 3 g before bedtime; significantly reduced fatigue and sleepiness, improved psychomotor vigilance the following day.
The Sleep-Promoting and Hypothermic Effects of Glycine Are Mediated by NMDA Receptors in the Suprachiasmatic Nucleus — 3 g before bedtime; shortened NREM sleep latency via core body temperature reduction, demonstrating a clear mechanism of action.
