NAD+ is one of the most talked-about molecules in longevity. Thunder Honey Daylight delivers it the way the research does: not as NAD+ itself, but as its precursor, nicotinamide riboside. Here is what each one is, how they connect to niacin (vitamin B3), and exactly what 300 mg of NR does and does not do, with the real human studies attached.
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell. Biochemically, it is a helper molecule that shuttles electrons during metabolism and acts as a substrate for a family of repair and signalling enzymes. It is one of the most abundant and essential molecules in human biology, which is simply a description of its role in the cell, not a statement about what our product does for you.
Two facts about NAD+ are well established in the scientific literature and worth stating plainly. First, the body cannot usefully absorb NAD+ taken by mouth as an intact molecule, which is why supplements use a precursor the body can convert. Second, measured NAD+ levels in human tissue tend to decline with age. Both are observations from the research, described here for context.
Because intact NAD+ is not well absorbed orally, formulators use building blocks the body already uses to make its own NAD+. The most studied of these in humans is nicotinamide riboside (NR). This is a formulation choice grounded in pharmacology: NR has the human bioavailability data that intact NAD+ does not.
Nicotinamide riboside (NR) is a naturally occurring compound and one of the precursors the body converts into NAD+. In Thunder Honey Daylight it appears at 300 mg per serving, the same dose used in the human trial that tested it most directly. Chemically, NR is a member of the niacin (vitamin B3) family, which is an important factual point for what we are allowed to say below.
The coenzyme cells use in metabolism and DNA-repair signalling. Not absorbed intact when swallowed, so it is not what goes in the scoop.
A precursor the body converts into NAD+. Well absorbed orally, with human data. This is the 300 mg active in Daylight.
The vitamin family NR belongs to. Nicotinamide is a recognised form of niacin, which matters for what can be claimed.
Nutrient Reference Value. For niacin the EU NRV is 16 mg; a food is a "source of" niacin at 15% of that, i.e. 2.4 mg per portion.
In a randomised, double-blind trial of 140 adults, NR raised whole-blood NAD+ in a clear, dose-dependent way. Thunder Honey Daylight uses the exact 300 mg dose tested in that study, which is why we can describe the NAD+ rise factually rather than estimate it.
Conze, Brenner & Kruger, 2019, Scientific Reports. 140 healthy overweight adults aged 40–60, 8 weeks, randomised double-blind. Whole-blood NAD+ rose dose-dependently: +22% at 100 mg, +51% at 300 mg, +142% at 1,000 mg. PMID 31278280
Trammell et al., 2016, Nature Communications. Established the oral bioavailability of NR and a dose-dependent NAD+ rise in humans. PMID 27721479
Where we stop. That NR raises NAD+ is shown in humans. That a higher NAD+ level then makes you feel more energetic, perform better, or live longer is not proven in people: the functional trials below were null or non-significant. So we describe the NAD+ rise as a fact and make no energy or longevity promise from it.
It would be easy to imply that raising NAD+ delivers more energy or a longer healthspan. The honest reading of the human evidence is more careful. Trials that looked for downstream functional benefits, rather than the NAD+ rise itself, have largely come back null or non-significant.
Dollerup et al., 2018, American Journal of Clinical Nutrition. 2,000 mg/day NR, 12 weeks, insulin-resistant men. Safe, but no improvement in insulin sensitivity, body composition, or resting energy expenditure. PMID 29992272
Martens et al., 2018, Nature Communications. 1,000 mg/day NR. Raised NAD+; blood-pressure and arterial-stiffness changes did not reach statistical significance. PMID 29599478
Our position: we make the claim the trials actually support, that NR is a precursor and that the studied dose raised measured NAD+, and we do not borrow the energy or longevity story that the functional trials did not deliver.
In the EU, "boosts NAD+", "cellular energy", "anti-ageing" and "longevity" are not authorised claims and we do not use them. But the nicotinamide in our NR is a recognised form of niacin (vitamin B3), a vitamin that carries a full set of authorised EU health claims with fixed legal wordings. Where the niacin dose qualifies and is declared on the label, these exact wordings become usable. They are reproduced here verbatim from Commission Regulation (EU) No 432/2012.
"Niacin contributes to normal energy-yielding metabolism."The legal equivalent of an energy message, framed as the body's own metabolism.
"Niacin contributes to the reduction of tiredness and fatigue."The authorised tiredness and fatigue wording.
"Niacin contributes to the normal functioning of the nervous system."A legitimate nervous-system claim.
"Niacin contributes to normal psychological function."The authorised stand-in for a mind / mental-function message.
"Niacin contributes to the maintenance of normal skin."A real skin claim, sourced from the vitamin.
"Niacin contributes to the maintenance of normal mucous membranes."Authorised; rarely used in consumer copy.
Conditions of use. An authorised vitamin claim can only be used if the product is a "source of" that vitamin, at least 15% of the 16 mg niacin NRV, i.e. 2.4 mg niacin equivalents per portion, with niacin declared on the supplement-facts panel. Our 300 mg NR clears that bar comfortably on dose, but the declared niacin-equivalent figure must be confirmed by the formulator and a regulatory advisor before any wording goes live. The claim is sourced from niacin the vitamin, never from NAD+.
