RetraBurn Supplement Facts: Serving Size and Panel

Row	Amount per serving	% Daily Value
Calories	0	–
Chromium (as Chromium Picolinate)	7 mcg	20%
Proprietary Blend	15.47 mg	†

Serving size 1 ml. Servings per container 30. The dagger marks a row for which no Daily Value has been established. The chromium row’s Daily Value carries the panel’s own footnote marker, and that footnote reads: “Percent Daily Value (DV) are based on a 2,000 calorie diet.”

The 21 blend members, in the panel's own order. One declared weight covers all of them and no split appears between them.

10 entries carry the caret for a 20:1 concentrate, African mango alone carries the mark for a 10:1 concentrate, and 10 carry neither because they are not plant extracts.

Other ingredients, as printed: water, natural flavors, potassium sorbate, stevia, xylitol, citrus extract.

The footnotes, as printed:

• “Not a significant source of saturated fat, trans fat, cholesterol, sodium, dietary fiber, total sugars, added sugars, protein, Vitamin D, calcium, iron, or potassium.”
• “Percent Daily Value (DV) are based on a 2,000 calorie diet.”
• “Daily Value (DV) not established.”
• “Sourced from a concentrate with a 20:1 extract equivalent.”
• “Sourced from a concentrate with a 10:1 extract equivalent.”

A proprietary blend is a legal construction rather than a marketing one. The labelling rule for a Supplement Facts panel allows a manufacturer to group ingredients under a single name and declare one weight for the group, provided two conditions are met.

The members must be listed, and they must be listed in descending order of predominance by weight. The total weight of the blend must be declared. The regulation setting that out is public and short, and it is the reason a reader can learn anything at all from a row that looks like a wall of names.

This panel satisfies both. All 21 members are printed, in order, with their extract marks attached, and 15.47 mg appears in the amount column. What the rule does not require is the split between the members, and that is the figure this label keeps.

Two things follow for a reader. The order is information: maca is heavier than African mango, which is heavier than grape seed, and L-carnitine at the end of the list is the lightest thing in the bottle. And the total is a ceiling: no member can exceed it, which is what makes any comparison with published research possible without knowing the split.

Arithmetic from the panel's own two figures and its servings-per-container line. Nothing here is a dose recommendation.

Two of those rows are worth pausing on, because they are the figures a buyer actually spends money on.

Four hundred and sixty-four milligrams is the whole blend in a month, shared 21 ways. Even the six-bottle pack, which is half a year of daily servings, carries less than three grams of blend in total. Those are the numbers behind a purchase, and they are worth having in mind when the per-bottle price is being compared against a single-ingredient capsule.

Two hundred and ten micrograms is the chromium in a month. For scale, the Cochrane review of chromium picolinate pooled trials running at 200 to 1,000 micrograms a DAY, so a whole bottle of this carries roughly one day of the smallest dose that review assessed. That is a comparison rather than a criticism: the panel presents its chromium as a fifth of a Daily Value, which is exactly what it is.

Underneath the panel, in smaller type, the label prints: water, natural flavors, potassium sorbate, stevia, xylitol, citrus extract. Six items, and on a liquid product they account for almost the entire volume of the bottle.

That line is the difference between a supplement panel and a full ingredient list. The panel above it carries what the product is sold for. The line underneath carries what makes it a liquid a person will swallow: a base, a preservative, two sweeteners and two flavour components.

It is also the line to read first for anyone avoiding a specific substance, because sweeteners and preservatives appear here rather than on the panel. Xylitol is the one worth knowing about for a reason unrelated to the person taking it: it is seriously toxic to dogs, so a bottle belongs in a cupboard rather than on a low shelf in a house with one.

Three questions are settled by this panel outright, and one is left open. Stating which is which is the whole job of this section.

Settled: how much chromium, and in which form. 7 mcg as chromium picolinate, 20% of the Daily Value, arithmetic exact. Settled: which twenty-one things are in the blend and in what order of weight. Settled: how much blend there is in total, 15.47 mg a serving.

Open: how that total divides. Maca could be most of it or a tenth of it, and the label gives no way to tell. Every member's individual amount is therefore known only as a maximum.

What makes the open question workable is that the maximum is small enough to answer with. The trials behind these ingredients used 500 mg of forskohlii extract, 600 mg of gymnema, 300 mg of EGCG and two grams of carnitine a day, and none of them is reachable inside 15.47 mg however it is divided. So the split, while genuinely missing, does not change the conclusion. The full comparison is set out on the home page under honest dosage analysis.

The credit due here is real and is worth saying in the same breath. A label that declares its blend total, names every member in order and footnotes both of its extract ratios has given a reader more to work with than most of this category does, and it is the reason this page could be written at all.
