The evidence, cited

The science behind Daylight, cited in full.

We built Daylight active by active, choosing each one for a reason and reading the research before it went in. This page gives every ingredient its own section: what it is, why we chose it, and the real studies that explore it, linked so you can read them yourself. We name each active and its dose, and we let the research speak for itself. Developed in Sweden.

  • 11 actives, each with its own section
  • 30+ studies cited, linked by PMID
  • Third-party tested by Eurofins

The honesty key

How to read this page.

Every active below gets its own section, in the same shape: what it is, the reason we chose it, the research that explores it, and the dose and form we use. We link the studies so you can read them yourself. Throughout, we are describing what the research investigated, not promising what Daylight will do for you. The depth of research varies by ingredient, so each section carries a small marker, not as a verdict on the ingredient, but as a straight signal of how much human research exists today.

Well-established

Multiple good human trials, or a strong review, several at or near our dose. A deep, mature evidence base.

Actively researched

Real human trials are building, with promising signals. We summarise what they explored and link them in full.

Early and traditional

Long traditional use plus early, mechanistic, or higher-dose research. Chosen for the formula, with the science still emerging.

Research summary

The whole evidence base, added up and linked.

Some brands print a big "studies" number and leave it at that. We built ours from the actual reference list we keep internally, and we link the papers on this page so you can open them yourself. Every figure below is countable in our citations file. This is the real shape of the research behind the formula.

Chaga, MCT, bee propolis, and cacao. Long traditional use, with early and mechanistic research.

How we counted, in full. The marker on each ingredient reflects how much human research exists today, on a simple scale: well-established (multiple good trials or a strong review, several at or near our dose), actively researched (real human trials that are building, sometimes smaller or at a different dose), and early and traditional (long traditional use plus early, mechanistic, or higher-dose research). Counts are of cited references, not an inflated "total studies on the ingredient" figure, and one active can sit in more than one band. We describe what each study investigated rather than stating what the product does, because most of these actives have no authorised EU health claim; the only stated product benefits on this page come from the authorised niacin (vitamin B3) wordings. This is an educational research review, not medical advice.

The most direct human data

NR and NAD+, measured at our exact dose.

This is the most directly studied active in the formula, and it is why we chose nicotinamide riboside as our B3. NAD+ is a coenzyme found in every cell, where it takes part in metabolism and DNA-repair signalling, a description of its role in the body, not a statement about what our product does for you. In a double-blind trial of 140 adults, NR raised whole-blood NAD+ in a clear dose-dependent way. At the 300 mg dose we use, measured NAD+ rose by 51% over eight weeks.

The study

Conze, Brenner & Kruger, 2019, Scientific Reports. 140 healthy adults, 8 weeks, randomised double-blind. 300 mg/day raised blood NAD+ by 51%. PMID 31278280

300 mg/day, our dose+51% NAD+
8 weeks
1,000 mg/day in the same trial+142%
higher dose
100 mg/day in the same trial+22%

What we can say, and how: NR is a recognised form of niacin (vitamin B3), and at our 300 mg dose it clears the EU threshold for the authorised niacin claims. That lets us say, in the official wording, that niacin contributes to normal energy-yielding metabolism and to the reduction of tiredness and fatigue (subject to niacin being declared on the label). We make the energy point through the vitamin, not through NAD+: "raises NAD+", "cellular energy" and "longevity" are not authorised EU claims, so we report the NAD+ measurement as research and route the benefit through niacin.

The formula, one active at a time

Every active, and the reason it is in the cup.

Eleven actives, each chosen on purpose. For every one: what it is, why we put it in Daylight, the research that explores it, and the dose and form we use. We describe what the studies investigated and link them in full. We are not telling you what the drink will do for you, we are showing you the thinking and the evidence, and letting you read it yourself.


Every ingredient, in full

The complete write-up for each of the eleven actives, what it is, why we chose it, the trials that have explored it and the exact dose in Thunder Honey, lives on the ingredients page.

The dose difference

Same 5:1 and 10:1 extracts, ten times the dose.

This is the deep version of the comparison. We use a concentrated dual-extract, the quality standard the best brands use. The difference is how much goes in. Many products add about 100 mg of the concentrated extract, then print "1,000 mg" by quoting the raw mushroom it came from. We put a full 1,000 mg of the extract itself in every scoop, for each mushroom. This is a factual comparison of quantities, not a benefit claim.

Thunder Honey, per mushroom1,000 mg of extract
a full gram, in the scoop
Many "1,000 mg" brands~100 mg of extract

A full 1,000 mg of dual-extracted fruiting body per mushroom, the amount clinical studies use, third-party tested by Eurofins. We use the fruiting body, not mycelium grown on grain, and every milligram is in the scoop, not in a raw-weight figure on the front of the pack.

  • Fruiting body, not mycelium
  • A full gram, not 100 mg
  • Every mg is in the scoop

Quick tip. By law, ingredients are listed by weight, highest first. If a label lists a 300 mg ingredient before its mushroom, that mushroom is under 300 mg, whatever the front says. The order tells you the real dose. Read the full method on the dual-extracted mushrooms page.

Stimulant-dependent energy vs natural energy

The caffeine rollercoaster vs your natural rhythm.

A general illustration of two energy patterns people describe through a day, measured against their own natural baseline. One person leans on a stimulant, spikes hard, then dips below where they started, the cycle that has them reaching for the next cup. The other isn't dependent on a stimulant at all: their natural, stimulant-free energy rises gently in the morning, stays steady through the day, and eases back by evening, with no spike to crash from. The shapes are an illustration of those patterns, not measured data about what any product does to your body.

Illustration only. Not trial data, not a health claim.

  • Natural rhythmA person's own steady level through the day, the line everything else is measured against. Stimulant-free energy rises gently in the morning, stays steady through the day, and eases back by evening, no spike to crash from.

  • Caffeine-dependentA spike, then a dip many people feel below where they started, the cycle that has you reaching for the next cup.

  • Thunder Honey: no added caffeineMade without added caffeine, carrying only the trace found in cacao. Contains niacin, which contributes to normal energy-yielding metabolism and the reduction of tiredness and fatigue.1

Honest framing. An illustration of stimulant-dependent versus stimulant-free energy patterns. Not data from a trial of Thunder Honey and not a health claim. The lines show patterns people describe, not numbers from a study. We are made without added caffeine as a matter of composition, carrying only the trace found in cacao; we do not claim the product gives you energy. The one authorised energy-adjacent wording we can use comes from niacin (vitamin B3) via the nicotinamide in our NR, "contributes to normal energy-yielding metabolism", subject to the dose being declared.

How we formulate

Based on research, not trends.

How we approach formulation, stated as our process and not as a promise about results. The figures below describe how we built and test the product, not a clinical outcome you are guaranteed.

2 years, 28 formulations

We spent two years and 28 iterations getting the doses, forms and taste right, then locked the formula so every batch is the same.

11 actives, each named at its dose

Every active and its exact dose is printed on the label, no proprietary blends hiding small amounts behind a big front number.

Dual-extracted, full-gram mushrooms

A full 1,000 mg of dual-extracted fruiting body per mushroom, the form and dose the research uses, not mycelium-on-grain.

Third-party tested by Eurofins

Every batch is independently tested for purity and potency. Developed in Sweden, formulated to Nordic standards.
