Label arithmetic
What a capsule can actually hold
A capsule holds roughly 500 to 800 milligrams of powder. A two-capsule serving is therefore about a gram and a half, and if a proprietary blend claims 1000 mg of actives across nine ingredients, each one gets an average of 111 mg. That single sum tells you which ingredients on a label can be present at a studied dose and which are names printed for effect.
The question nobody asks at the shelf
Pick up any multi-ingredient supplement and read the front. It will name several ingredients, often impressively many. Now ask the question almost nobody asks: where, physically, is all of that supposed to fit?
It is not rhetorical. A capsule has a fixed internal volume, the powder that goes in it has a measurable density, and the space is small enough to do arithmetic on. Once you know roughly how small, half the supplement market becomes easy to read.
What is actually in a capsule
Working from the outside in, a typical botanical capsule contains:
- The shell — gelatin or a vegetarian cellulose alternative. Structure, not formula.
- A filler — rice powder, microcrystalline cellulose or maltodextrin. It takes up whatever space the actives do not.
- A flow agent — magnesium stearate, usually well under one percent. It stops the powder jamming the filling machine.
- The actives — whatever is left after the above.
The product this site sells lists its other ingredients as Gelatin Capsule, Rice powder, Magnesium Stearate Vegetable Grade. That is shell, filler and flow agent: a completely standard set, and a useful reminder that a capsule's contents are not all formula.
A size 0 capsule — the common one — holds somewhere between 400 and 700 mg of powder depending on density. A size 00 holds more. Nobody publishes which size they use, so you are estimating, but the order of magnitude is not in dispute.
The capacity table
This is the useful part. Compare what each ingredient is studied at against what a shared blend can hold.
| Ingredient | Studied at | Fits at 111 mg? | Why |
|---|---|---|---|
| Vitamin D, B12 | Micrograms | Easily | Micrograms are trivial to deliver |
| Chromium | 200-1000 mcg | Easily | Small mineral doses fit comfortably |
| Standardised botanical extract | 100-600 mg | Sometimes | Only if it takes a large share of the blend |
| Cinnamon powder | 1-6 g | No | A gram is the whole blend |
| Bitter melon | 2-6 g | No | Not alongside eight other ingredients |
| Garcinia HCA extract | 1-2.8 g | No | More than the entire blend weighs |
| L-lysine | 1-3 g | No | Even as the whole blend it falls short |
| Apple cider vinegar | 15-30 ml liquid | No | A different format entirely |
The rule this produces
Minerals and vitamins in a capsule: an excellent idea, because the doses are small enough to deliver honestly. A gram-dose ingredient inside a shared blend: a name on a label. If a formula lists cinnamon, bitter melon or garcinia among nine ingredients under one 1000 mg total, assume each amount is small — because the arithmetic leaves no alternative.
We sell a nine-ingredient blend and we publish this anyway
Six of the nine ingredients in the product this site sells are studied above the average share of its blend. That is on the home page, the ingredients page and this post, because a reader who works it out afterwards has been sold something.

Where extracts genuinely change the answer
Having made the case against long lists, here is the strongest counter-argument, and it is a real one that deserves stating properly.
A standardised extract concentrates the active fraction of a plant. A 10:1 extract means ten parts of raw material produced one part of extract, so 100 mg of extract corresponds to a gram of the original herb. Applied honestly, this is how a capsule can carry a meaningful dose of something normally measured in grams, and it is why “the trials used 6 grams” is not always the knockout argument it appears to be.
The condition attached
It only works if the ratio is printed. “Cinnamon extract” with no ratio tells you nothing: it could be 10:1 or it could be dried bark ground finer than usual. A label that has gone to the trouble of standardising its extracts almost always says so, because it is a selling point. A label that does not print ratios has usually not paid for them.
Of the seven botanical ingredients in the blend this site sells, the number with a published extract ratio is zero. That does not prove they are unstandardised. It means you cannot tell, which for a buying decision amounts to the same thing.
The long-list problem
Here is where capacity gets misused. A long ingredient list sells: nine names look like more value than two. But nine names sharing 1000 milligrams means each gets a fraction of what one alone could have had.
| Formula | Blend total | Average per ingredient |
|---|---|---|
| One ingredient | 1000 mg | 1000 mg |
| Three ingredients | 1000 mg | about 333 mg each |
| Six ingredients | 1000 mg | about 167 mg each |
| Nine ingredients | 1000 mg | about 111 mg each |
| Fifteen ingredients | 1000 mg | about 67 mg each |
Those are averages, and the descending-order rule guarantees the later entries get less than the average rather than exactly it. The shape is what matters: every name added divides the same small space. A two-ingredient formula with published amounts is usually a stronger product than a fifteen-ingredient one without.
How to check in ten seconds
Count the actives on the front
More names is not more product. It is more division.
Turn the bottle over
Find the Supplement Facts panel and look for an amount column with individual numbers in it.
If it is a blend, divide
Total divided by the number of ingredients. That is your average share, and your ceiling for the last-listed ingredient.
Look up one gram-dose ingredient
Cinnamon, bitter melon, garcinia, lysine. If it is in there without an amount, you now know roughly what it cannot be.
Check the serving size
Two capsules a serving doubles the actives — and halves how long the bottle lasts.
Decide what you are paying for
Breadth has genuine value for some people. Just make the trade knowingly.
When a blend is the right choice
Three situations where a multi-ingredient capsule is the sensible purchase rather than the naive one.
When the ingredients are small by nature
A blend of minerals and vitamins can deliver every one at a studied dose inside a single capsule. The arithmetic only bites when gram-dose botanicals are involved.
When adherence is the real problem
A product taken four days out of seven is being sampled, not tested. One bottle you actually finish beats four you rotate between and forget.
When you genuinely want breadth
If the goal is to touch several ingredients at modest amounts rather than one at a researched dose, a blend does that and does it cheaply. It is a legitimate goal; it is just not the one the front of the bottle usually implies.
And the general rule: the best supplement is the one you keep taking, at a dose that means something. Those two conditions pull in opposite directions more often than the industry admits, and a nine-ingredient gram is what that tension looks like when it is resolved in favour of the label.
Two capsules is not twice the information
A serving size of two capsules doubles the amount of blend and changes nothing about what you know, which is a distinction worth holding onto.
Panels are written per serving. A blend printed as 1000 mg at two capsules a serving is 500 mg per capsule; the same product relabelled as 500 mg at one capsule a serving looks half as impressive and is identical. Serving size is the easiest lever in supplement labelling and the one buyers check last.
On this product the lever is pulled in an unusual direction: the directions allow one capsule or two, so the buyer chooses their own serving without guidance. That is the only place we have seen a label hand that decision over, and it means the same bottle can be a 30-day supply or a 60-day one depending on a choice the label declines to make.
Read the panel, then the front
In that order, on every bottle you ever pick up.
