Our science
How we think
Science at AMINAH VITAL starts with a simple belief: supplementation should be clear, intentional and grounded in research — not trends, noise or excess. Below are the principles behind every formula we make, and the research behind AMINAH DAY.
01 Transparency
Trust is built through clarity. Every active ingredient we use is named with its exact amount. No proprietary blends, no totals that hide individual doses, no ingredient listed without its quantity.
Transparency is not a feature of our marketing. It is the condition for everything else we say. What you see is exactly what you take.
02 Meaningful doses
Naming an ingredient on a label is easy. Including enough of it to matter is the real work of formulation.
When we formulate, we aim for amounts in line with those used in human research, wherever the formulation and the evidence allow. And where an amount falls short of what has been studied, we say so openly — you will find the comparison, ingredient by ingredient, in the research below.
03 Purpose, not decoration
A long ingredient list can look impressive, but the number of ingredients says little about the quality of a formula. We do not add ingredients to make a label look more complete.
Each ingredient needs a clear reason to be there and a defined place within the whole: the right ingredient, in the right form, for a clearly defined purpose. We think of a formula as one considered design — not a collection of separate parts.
04 Quality over quantity
More ingredients do not automatically make a better formula. More claims do not make a better product. More complexity does not make it more effective.
We would rather make fewer, deliberate choices — and be able to explain every one of them.
05 Science with purpose
Our formulas are developed by experienced scientists and research professionals. We look first to peer-reviewed human research, and we choose each ingredient for what it does — not for how it looks on a label.
Evidence guides the decisions that matter most in a formula, including the form of each nutrient, from chelated minerals to methylcobalamin. Where the research is limited, we treat it as limited.
06 Evidence without overpromising
A study observing a result is not a promise. We are careful not to turn research into claims it cannot support, and we do not present supplements as miracle solutions.
Our language should never run ahead of the evidence. Clarity over exaggerated promises — always.
07 Simplicity without compromise
We want to make supplementation simpler — one considered formula instead of a shelf of separate products. But simple should never mean superficial: you see a simple daily ritual, and behind it sits careful formulation.
Wellbeing is built over time, not overnight. That is why we design for real life — something easy to take every day, consistently — rather than for quick fixes.
08 Informed choice
We do not rely on people knowing little. We want you to understand what you are taking, why you are taking it, how much it contains and what role each ingredient plays.
We do not hide complexity. We explain it, simply — which is why the full formula, every dose and the research behind it are published for anyone to read — the formula on our ingredients page, the research below.
The evidence
The studies behind each ingredient in AMINAH DAY — what was studied, in whom, at what amount and what was found. Reported as the research reports it, without overstatement.
How to read this research
A clinically relevant dose is an amount in line with what has been used in human research. For every ingredient, we compare the amount in AMINAH DAY with the amount studied.
Where our amount sits within that range, we say so. Where it does not — or where the research used a different form or extract — we mark it as under review. We would rather show you the gaps than hide them.

What was studied
An 8-week randomised, double-blind, placebo-controlled trial in healthy overweight adults, testing 100, 300 and 1,000 mg of nicotinamide riboside chloride a day.
In AMINAH DAY
200 mg
Amount studied
100–1,000 mg/day
Our 200 mg sits between the 100 mg and 300 mg doses tested, in the same form.
What was found
All three doses raised whole-blood NAD+ levels in a dose-dependent way — by 22%, 51% and 142% — within two weeks, and were well tolerated.

What was studied
A meta-analysis of 13 randomised controlled trials (1,126 participants, healthy and with various health conditions), and a small crossover trial in 17 healthy volunteers who took 100 or 300 mg a day for 8 days.
In AMINAH DAY
100 mg
Amount studied
100–300 mg/day
100 mg matches the lower dose tested in the crossover trial; there, the effects were seen with 300 mg. The meta-analysis found larger effects at higher daily doses.
What was found
In the meta-analysis, CoQ10 reduced fatigue scores compared with placebo, with larger reductions at higher daily doses and longer durations. In the crossover trial, the effects on fatigue and performance during an exercise task were seen with 300 mg.

What was found
We have not yet found human research at an amount comparable to the 1,000 mg in AMINAH DAY, so no study is cited here.

Research on citicoline in healthy people.
What was studied
A randomised, placebo-controlled trial in 75 healthy adolescent males (250 or 500 mg a day for 28 days), and a 12-week randomised, double-blind trial in 100 healthy adults aged 50–85 with age-associated memory impairment (500 mg a day).
In AMINAH DAY
250 mg
Amount studied
250–500 mg/day
Our 250 mg is the lower of the two doses tested in the first trial. Both studies used Cognizin®, a branded form of citicoline.
What was found
In the first trial, citicoline was associated with better attention and psychomotor speed than placebo. In the second, it improved episodic and overall memory scores compared with placebo.

L-theanine (Puretheanine®, from Camellia sinensis leaf)
In AMINAH DAY200 mg
About this ingredient →What was studied
A 4-week randomised, placebo-controlled crossover trial in 30 healthy adults (200 mg a day), and a systematic review of randomised controlled trials.
In AMINAH DAY
200 mg
Amount studied
200–400 mg/day
Our 200 mg matches the amount used in the trial and sits at the lower end of the range in the review.
What was found
In the trial, L-theanine reduced scores for stress-related symptoms and improved sleep-quality scores and some measures of cognitive function. The review concluded that 200–400 mg a day may help reduce stress and anxiety in people exposed to stressful conditions, and called for larger and longer studies.

Root extract, standardised to 3% rosavins and 1% salidroside
In AMINAH DAY300 mg
About this ingredient →What was studied
A systematic review of 11 controlled trials, and a 14-day trial in 80 mildly anxious adults — without a placebo group — using 400 mg a day of a specific extract.
In AMINAH DAY
300 mg
Amount studied
400 mg/day (different extract)
The studies used specific extracts that differ from ours. We are reviewing the evidence for our extract and amount.
What was found
The review found some evidence that Rhodiola may help with physical performance and mental fatigue, but described the research as contradictory and limited by methodological flaws. In the 14-day trial, the extract was followed by lower self-reported anxiety and stress.

About this ingredient →What was found
Most research on butyrate concerns what gut bacteria produce in the colon. Human studies of oral calcium butyrate in healthy people are limited, so we have not cited a study here yet.

The research summaries describe what was observed in the studies cited — in the people, forms and amounts that were studied. They are not claims about the effects of AMINAH DAY. Where a study was funded or co-authored by an ingredient’s manufacturer, we note it. Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.
