Caffeine Anhydrous
138 mg · the one amount that is large
The only ingredient here at a dose nobody has to argue about. The FDA puts 400 mg a day as the figure that “is not generally associated with dangerous, negative effects” for healthy adults, and describes that as two to three 12-ounce cups of coffee. This capsule is about a third of that, before you count your own coffee.
Green Coffee Bean Extract
130 mg · closest to a studied dose
Printed with its species, its plant part and its standardisation: <i>Coffea robusta</i>, seed, 50% chlorogenic acids. The NIH's weight-loss review describes trials giving 180 or 200 mg a day of green coffee extract, so 130 mg is genuinely in the same order of magnitude — the only ingredient here of which that is true.
Garcinia Extract
130 mg · 15 to 43 times under
<i>Garcinia cambogia</i>, fruit, 50% HCA — so 65 mg of hydroxycitric acid. The NIH records studies using <b>1,000 to 2,800 mg a day of HCA</b>. It also records 10 cases of liver toxicity in people taking garcinia-containing products, resulting in one death and two liver transplants, while noting causation could not be established.
Raspberry Ketone
130 mg · no human evidence to compare with
The NIH's position on this one is short: it has been “studied only in combination with other ingredients” and there is “insufficient research to draw firm conclusions”. There is no dose to compare 130 mg against, because there is no single-ingredient human trial to draw one from.
Green Tea Extract
130 mg · just under the studied band
The best-specified line on the label: 98% polyphenols, 75% catechins, 45% EGCG, under 3% caffeine. That is 97.5 mg of catechins and 58.5 mg of EGCG. The NIH describes trials using catechin doses from 141 to 1,207 mg, so this sits just below the bottom of that range — closer than anything else here except the green coffee.
Chlorogenic acids
65 mg · the compound behind the green coffee
Half of 130 mg, because the label states the standardisation. This is the arithmetic a standardisation exists to permit: without it, 130 mg describes a weight of powder rather than a quantity of anything.
HCA
65 mg · the compound behind the garcinia
Also half of 130 mg. Set beside the 1,000–2,800 mg a day the studies used, this is between a fifteenth and a forty-third of a studied dose. The label printed the number that makes that visible, which is to its credit.
EGCG
58.5 mg · well inside ordinary practice
45% of 130 mg. Green tea extract has a documented liver-injury signal at high intakes — NCCIH notes injury has been reported “primarily [with] green tea extracts in tablet or capsule form” — and 58.5 mg is a long way below the intakes that signal is associated with. On this one the smallness is a safety margin.
Hypromellose
capsule shell
The only other ingredient on the label. A vegetable capsule, named, which is more than several products on this desk print. No fillers, no flow agents, no anti-caking agent.
“Contains Caffeine”
printed on the label
A plain-language caffeine statement directly under the other-ingredients line. It is not required by regulation in the way an allergen statement is, and printing it anyway is a small piece of good practice worth naming.
