Science-led formulation

Every ingredient has a job. Every formula has a strategy.

We do not throw fashionable ingredients into a capsule and hope for the best. We start with the outcome, map the connected biological pathways, then choose ingredients that contribute distinct and complementary roles.

Why formulation matters

A list of ingredients is not a formula.

A real formula is a system: an anchor ingredient, supporting pathways and delivery choices that make sense together.

That is why we explain not only what is inside every EverBright product, but why it is there.

01

Stimulant-free metabolic support

Fat Metaboliser

Seven ingredients. Six connected pathways. One deliberate strategy for supporting how the body transports fat, processes macronutrients and maintains normal metabolic function, without caffeine.

Explore Fat Metaboliser →
Transport

Acetyl-L-carnitine supports the mitochondrial fatty-acid transport rationale.

Metabolise

Choline and chromium provide recognised nutrient functions for lipid and macronutrient metabolism.

Complement

Catechins, olive polyphenols, prebiotic fibre and piperine broaden the formula beyond one mechanism.

Mitochondrial pathway1,000 mg

Acetyl-L-carnitine

What it contributes

Carnitine helps carry long-chain fatty acids into mitochondria, the cell structures where those fats can be used for energy.

Why it earns its place

It is the metabolic anchor of the formula and the largest active amount. We chose acetyl-L-carnitine to make fatty-acid transport a genuine formulation pillar, not label decoration.

What research indicates

The carnitine family has been examined in multiple human studies of fatty-acid oxidation, body weight and body composition, with modest average effects reported in some populations.

Catechin pathway500 mg · 225 mg EGCG

Decaffeinated green tea extract

What it contributes

A concentrated source of green-tea catechins, including a disclosed 225 mg of EGCG, selected for their role in metabolic and fat-oxidation research.

Why it earns its place

Green tea is one of the most extensively studied botanicals in weight-management research. We remove the caffeine so the formula is driven by standardised catechins, not a stimulant buzz.

What research indicates

Multiple human trials have explored green-tea catechins in relation to fat oxidation and body composition. Results vary, but the body of research gives this ingredient a clear reason to be here.

Gut pathway500 mg

Chicory-root inulin

What it contributes

A fermentable prebiotic fibre that introduces a gut-microbiome pathway to a formula otherwise built around mitochondrial, botanical and micronutrient support.

Why it earns its place

Metabolic health is not a single-pathway story. Inulin adds fermentable fibre and gives the formula a broader nutritional architecture instead of repeating the same mechanism seven times.

What research indicates

Human studies at gram-level intakes show that inulin can selectively increase beneficial gut bacteria, including bifidobacteria. Here it plays a complementary role within the wider formula.

Lipid + liver pathway250 mg · 82.5 mg choline

Choline bitartrate

What it contributes

Choline contributes to normal lipid metabolism and to the maintenance of normal liver function, both central to how the body handles fats.

Why it earns its place

It gives the formula a recognised nutritional foundation. Rather than asking plant extracts to carry the whole metabolic story, choline contributes a defined nutrient function.

What research indicates

Choline is an essential nutrient with authorised UK health claims for normal lipid metabolism and normal liver function when supplied at a qualifying amount.

Polyphenol pathway250 mg · 75 mg oleuropein

Olive leaf extract

What it contributes

A standardised olive polyphenol source selected to complement the formula’s glucose-regulation and wider metabolic pathways.

Why it earns its place

We use an extract standardised to 30% oleuropein, so you know the active polyphenol contribution: approximately 75 mg per daily serving, not an unspecified olive powder.

What research indicates

A randomised human crossover trial using 51.1 mg oleuropein reported improved insulin sensitivity and pancreatic beta-cell responsiveness in overweight men. Our serving supplies a comparable oleuropein amount.

Macronutrient pathway200 µg · 500% RI

Chromium picolinate

What it contributes

Chromium contributes to normal macronutrient metabolism and to the maintenance of normal blood-glucose concentrations.

Why it earns its place

It connects the formula to the metabolism of carbohydrate, fat and protein, complementing choline’s lipid and liver functions and the botanical components.

What research indicates

These functions are supported by authorised UK health claims. We use the picolinate form and disclose the full 200 µg daily amount.

Absorption support5 mg · 4.75 mg piperine

Black pepper extract

What it contributes

A standardised source of piperine included as formulation support, because what happens to ingredients after swallowing them matters too.

Why it earns its place

Piperine has been used across human pharmacokinetic research to influence the absorption or blood levels of selected compounds. It earns its place as part of the delivery strategy, not as another headline metabolic active.

What research indicates

Human studies have reported bioavailability effects in specific pairings, including curcumin and coenzyme Q10. That supports piperine as a considered formulation tool, while the effect still depends on the compound and dose.

02

Healthy-ageing formulation

Timeless

Three focused ingredients built around NAD+ availability, cellular housekeeping and polyphenol signalling. Each takes a different route; together they create a coherent cellular-support system.

Explore Timeless →
Replenish

Nicotinamide riboside provides the precursor at the centre of the NAD+ pathway.

Renew

Spermidine adds a distinct cellular-housekeeping and autophagy rationale.

Signal

Trans-resveratrol brings a complementary polyphenol and energy-sensing pathway.

NAD+ pathway300 mg

Nicotinamide riboside

What it contributes

An orally available precursor used by the body to make NAD+, a coenzyme involved in cellular energy production and many metabolic reactions.

Why it earns its place

NR is the clear anchor of Timeless. The 300 mg amount was selected to sit within the range directly examined in human bioavailability research, rather than appearing as a token inclusion.

What research indicates

Human studies show that oral NR can raise circulating NAD+ metabolites. A published pharmacokinetic study included a 300 mg dose, the same daily amount used in Timeless.

Cellular renewal pathway300 mg extract · 3 mg spermidine

Spermidine-rich wheat germ extract

What it contributes

A dietary polyamine selected for its relationship with autophagy, the cell’s internal recycling and housekeeping process.

Why it earns its place

It complements NR through a distinct cellular-maintenance pathway. The wheat-germ extract is standardised to a transparent 3 mg of spermidine, so its contribution can be assessed.

What research indicates

Spermidine is supported by a growing body of mechanistic, observational and early human research around healthy ageing and cellular maintenance. It is an emerging field, which is why we pair it with better-established NAD+ biology.

Polyphenol signalling100 mg trans-resveratrol

Liposomal trans-resveratrol

What it contributes

The polyphenol component of Timeless, selected for research around metabolic signalling, cellular stress responses and energy-sensing pathways.

Why it earns its place

We specify the trans isomer and use a liposomal delivery format because conventional resveratrol is rapidly metabolised. It completes the formula’s three-part strategy alongside NR and spermidine.

What research indicates

Resveratrol has been tested in many human studies, including trials near this dose, although results are mixed. The delivery format is a deliberate formulation response to its known oral-bioavailability challenge.

How we formulate

Built backwards from purpose.

Science-led does not mean finding one exciting paper after the formula is finished. It means making a chain of deliberate decisions before an ingredient earns its place.

01

Define the goal

Start with the biological question and the customer need, not the latest fashionable ingredient.

02

Map the pathways

Identify the connected processes that make the outcome more than a single-mechanism story.

03

Select with purpose

Choose the form, standardisation and amount that give each ingredient a defined role.

04

Build the system

Combine complementary jobs, remove duplication and make every active amount visible.

A note on the evidence

Confident, not careless.

The research above explains the scientific rationale for selecting each ingredient. Where we say “multiple studies indicate”, we mean research on that ingredient or nutrient, not a claim that the finished EverBright formula produced every reported result.

Effects depend on the ingredient form, amount, population and study design. Our finished formulas have not yet been tested in published clinical trials, so we do not call them “clinically proven”. We show the sources because informed customers deserve more than vague science language.
