The Science Behind Morning & Night: Clinical Trial Results Explained

From influencers peddling melatonin supplements to Fortune 500 CEOs scheduling meetings around their biological clock, circadian rhythm is reshaping how we think about optimisation. But circadian biology governs far more than sleep – your skin and systems undergo distinct metabolic shifts across the 24-hour cycle. Barrier function strengthens overnight, oxidative stress peaks during daylight and collagen synthesis follows temporal patterns dictated by cellular clocks. Energy metabolism, immune signalling, and neuroendocrine balance all operate on circadian schedules.

Despite the body's precisely timed biological programming, most nutritional interventions disregard chrononutrition – how our bodies react to nutrients delivered at various time points.


“The supplement was structured with both morning and night formulations, uniquely designed to meet the needs of the body at these two distinct time points.”


Morning & Night is different. Our gold-standard clinical trial, published in the Journal of Clinical and Aesthetic Dermatology, examined whether time-targeted supplementation – Morning formulation for defence and energy, Night for repair and recovery – would demonstrate superior efficacy compared to conventional approaches.

The data, observed over 12 weeks by board-certified dermatologists and researchers, suggest that aligning nutrition with circadian rhythm doesn't simply enhance results, it fundamentally changes them.

Skin, Sleep, and System Biology: A 24-Hour Perspective

Your skin isn’t just the canvas you slather in pricey serums and makeup, it’s the body’s largest, most dynamic organ. To frame skin purely as a cosmetic surface is to disregard its biological complexity – it is an immune, endocrine and metabolic organ, deeply integrated with systemic physiology – and, crucially, governed by circadian rhythm.

Across a 24-hour cycle, the body transitions between catabolic, stress-adaptive states (daytime) and anabolic, reparative states (nighttime). These shifts influence not only skin processes (such as barrier recovery and collagen synthesis) but also energy metabolism, immune signalling and neuroendocrine balance, all of which feed back into visible skin health.

Our gold-standard clinical trial published in the Journal of Clinical and Aesthetic Dermatology is notable precisely because it does not isolate skin from these systems. Instead, it evaluates a time-targeted nutritional intervention with both dermatological and whole-body endpoints.

Study Design: A Circadian-Timed Approach

Our independent, placebo-controlled, double-blind clinical study was conducted by a group of researchers and dermatology specialists and published in the Journal of Clinical and Aesthetic Dermatology. The lead investigators were Zoe Diana Draelos, Jennifer Linder and Anna Guanche, all of whom are board-certified dermatologists with experience in clinical research, particularly in cosmetic and aesthetic dermatology.

Researchers designed a gold-standard study:

  • 12-week, randomised, double-blind, placebo-controlled trial
  • 50 women, aged 35–65, with mild-to-moderate photoaging
  • Split-dose protocol: morning (defence/energy) and night (repair/recovery)

Outcomes included clinical grading, instrumental imaging and patient-reported measures spanning skin, energy, sleep, immunity and mood.

The Results Are In...

Week 4: Early Functional Shifts

By Week 4, changes were subtle but directional, primarily functional rather than structural.

  • Initial improvements in skin hydration and radiance (early barrier support)
  • Emerging increases in daytime energy, consistent with mitochondrial support ingredients
  • Early signals of improved sleep quality, suggesting alignment with circadian repair cycles

At this stage, the data reflects physiological priming – the groundwork for more visible changes.

Week 8: Statistically Significant Separation

By Week 8, the intervention group begins to diverge clearly from placebo across multiple endpoints:

Skin:

  • Hydration: ↑ (p < 0.001)
  • Dullness: ↓ (p < 0.001)
  • Firmness: ↑ (p = 0.035)
  • Overall appearance: improved (p = 0.010)

Systemic outcomes:

  • More consistent energy levels throughout the day
  • Noticeable improvements in sleep quality
  • Reported gains in mood and overall wellbeing

This phase marks a shift from subtle changes to clinically measurable improvements, particularly in barrier function and skin vitality.

Week 12: Structural and Multi-System Outcomes

By Week 12, results extend beyond surface-level improvements into structural and systemic domains.

Skin:

  • Sustained gains in hydration, radiance and firmness
  • Reduction in wrinkle breadth, confirmed via imaging (p = 0.018)
  • Improvements in texture, pigmentation, and overall skin quality


Whole-body outcomes:

  • Enhanced daytime energy (suggesting sustained mitochondrial efficiency)
  • Improved sleep depth and quality, supporting overnight repair
  • Indicators of stronger immune resilience, likely linked to reduced oxidative stress and inflammation
  • Continued improvements in mood and emotional balance


At this stage, the data suggests not just symptomatic change, but integrated, multi-system benefits.

Why Timing Drives Efficacy

The intervention’s design reflects principles of chrononutrition:

Morning (defensive / metabolic phase):

  • Antioxidants mitigate reactive oxygen species (ROS)
  • CoQ10 and acetyl-L-carnitine support ATP production and cellular energy

Evening (repair / regenerative phase):

  • Nutrients align with collagen synthesis, cellular repair, and immune modulation
  • Support for processes amplified during sleep (e.g., growth hormone release, DNA repair)

This temporal targeting enhances biological efficiency – delivering nutrients when the body is primed to use them.

An excerpt from the study summarises the unique benefit of our Morning supplement, designed to support cellular defence and energy:

“The morning formulation contained vitamin A, vitamin C , and vitamin E , which are important systemic and skin antioxidant vitamins. Vitamin D was also present for bone health and emotional well-being. The morning supplement also contained other trace nutrients, including iodine for thyroid health , the antioxidant ingredient selenium), and magnesium and zinc, which are found in matrix metalloproteinases. Flaxseed oil (1gm) was included as a phytoestrogen and a source of essential fatty acids (omega-3 and omega-6). Other antioxidant nutrients included l-cysteine and turmeric extract. Finally, the morning contained acetyl-l-carnitine and coenzyme Q10, which are important in cellular energy production. Acetyl-l-carnitine and coenzyme Q10 have been used in mature adults to decrease physical fatigue.”

And our Night supplement, designed to support cellular recovery and repair overnight:

“The night supplement was a different formulation designed to meet the needs of a body at rest.

It contained additional flaxseed oil, a phytoestrogen helpful in menopause-induced hot flashes, and l-cysteine. A variety of amino acids, such as lysine hydrochloride, l-glutamine, and l-arginine were also included. This combination of amino acids is purported to stimulate the pituitary gland to produce human growth hormone. Finally, alanine was incorporated for its ability to increase carnosine levels, which are important in glycation interference.”

From Routine to Rhythm

I’ve you haven’t ever considered (or even heard of) chrononutrition, now is the time to reframe supplementation as time-resolved rather than static. By aligning with circadian biology, Morning & Night demonstrates measurable improvements across:


Our main takeaway from our gold-standard study is to prioritise precision over excess in supplementation – results are linked more to when than how much.

The study wrote: “The studied supplement was not intended to correct nutritional deficiencies, but rather to provide targeted support through a carefully constructed set of nutrients, including amino acids, vitamins and minerals. For example, carnitine, iodine, magnesium, and coenzyme Q10 were intended to increase cellular energy production,” for measurable improvements to skin, sleep, energy, immunity, mood and more – after just a few weeks of use.

I have so much energy

My hair has stopped falling out, my skin is glowing and l am sleeping well and have so much energy... more than l have had in a long time. I am so pleased l don't have to take countless supplements a day anymore that were doing nothing for me. Just having Lumity is perfect for me and seeing the results so soon is a win!
