Dosing a Liquid Supplement Correctly

Liquid dropper supplements introduce a measurement problem that capsules do not, and most of the confusion comes from one ambiguous term.

Dropperful versus drop versus millilitre

A dropper on a typical supplement bottle holds around one millilitre when the bulb is squeezed and released once, which usually fills the pipette to roughly the halfway mark rather than to the top. A full dropperful in common usage means that single-squeeze fill, not a pipette filled to the brim. A drop is much smaller and varies with viscosity and dropper design. Labels that specify millilitres are clearer than those specifying dropperfuls, and where a label uses the latter, checking the graduation marks on the pipette resolves it.

Getting a consistent dose

Squeeze the bulb fully, release, and let the liquid settle before reading against the marks. Hold the dropper vertically. Do not top up by squeezing again, as this introduces air and inconsistency. If your bottle's pipette is unmarked, a small oral syringe from a pharmacy gives an accurate measure and costs very little. Consistency between doses matters more than precision to the tenth of a millilitre.

Common errors

Not shaking the bottle, which matters where ingredients settle. Storing in direct light or heat. Touching the dropper to the tongue and returning it to the bottle, which introduces contamination. Assuming a bigger dose works faster or better, which is not how any of this works and increases the chance of adverse effects. And taking it inconsistently, which makes it impossible to evaluate whether the product is doing anything.
