What is a dropperful?

A dropperful is the amount of liquid that fills the glass tube of a dropper after one full squeeze and release of the bulb. This differs from a full dropper or the entire glass tube. Dropperful is commonly used as a measurement when dosing liquid tinctures. The liquid may not fill the whole tube, but the amount drawn with a standard squeeze is considered a dropperful.

With one full squeeze of our Vitamin D3 & K2 with MCT Oil, the bulb will draw up approximately 0.75 mL of oil, which is the product's suggested usage amount.
