Sizes and counts

The range
Seventy-five to 950 mL across 157 containers, which covers a 30-count trial through a 180 or 240-count value size. That is a genuinely useful span for a supplement line.
Capacity does not map to count
A size 0 capsule, a size 00, a small tablet and a large softgel occupy very different volumes, and they pack differently. There is no milliliter figure that converts, which is why the answer is to fill and count.
So measure it once per product
Fill the candidate bottle with the actual dosage form to the level you intend, count it, and record the pairing. That table is what lets you choose a bottle for a count rather than guessing.
Headspace is the thing you are really choosing
Enough that the contents do not jam, little enough that they do not tumble and chip. Filler makes up the difference, and a bottle sized to the count needs less of it.
And the count decides the iron answer
Which makes this section and the iron rule section the same decision seen from two directions. Choosing a 180-count because the bottle looks better on shelf is choosing a package iron total too.
Wide necks across the range
89-400 on 69 containers and 70-400 on 40. A wide mouth matters for filling speed and for a customer reaching the last few capsules, and it is also where the child-resistant closure options are thinnest.
Cost the bottle per unit sold
Filling, sealing, labeling and the desiccant are close to flat per bottle, so a 30-count carries far more packaging cost per capsule than a 180. Decide what each size has to earn rather than reading one figure across.
