A dropper bottle is convenient but less forgiving than a capsule. Here is how to store liquid botanicals, how long they last once opened, why doses drift and how to measure one dropper accurately.
Why Liquids Degrade Faster
Plant extracts in water or glycerin are exposed to oxygen, light and microbes each time the bottle opens. Amber glass blocks light, preservatives and low pH slow microbes, but the clock starts at first opening. Potency of light-sensitive compounds such as catechins declines over weeks in poor conditions.
Storage and Shelf Life
Keep the bottle capped, in a cool cupboard away from the stove and window, or in the fridge if the label allows. Most liquid botanicals are labelled for 60–90 days after opening; a 30-day bottle used daily is within that comfortably. Discard if the liquid clouds, separates in a new way, smells off or shows any growth at the dropper tip. Never let the dropper touch the mouth and then return to the bottle.

Read the Olivaro ReviewDropper Accuracy
A 'dropper' is typically about 1 mL when the bulb is squeezed once and released, but droppers fill to between 0.6 and 1.0 mL depending on technique and the viscosity of the liquid. Many droppers have a 1 mL mark; fill to the line for consistency. Drops themselves vary in size with the tip and the liquid, so counting drops is less reliable than the line.
Dose Discipline
Take the labelled dose at the same time daily. Shake first, since some ingredients settle. If the label gives a range, start low. A 30 mL bottle holds about 30 single-dropper doses; using two droppers halves the supply, which matters for cost comparisons between pack sizes.
Where Olivaro Fits
Olivaro comes in a 30 mL amber dropper bottle with a one-dropper morning dose and a label range of one to two. Our review page recommends starting with one, shaking first and taking it in water or under the tongue, and notes the 30-day supply at one dropper.

Key Takeaways
- Liquids degrade with light, air and microbes after opening.
- Cool, dark storage; most last 60–90 days opened.
- Fill to the 1 mL line; drop counting is unreliable.
- Shake, same time daily, start at the low end of the range.
Frequently Asked Questions
Should I refrigerate liquid supplements?
If the label allows, refrigeration extends life; otherwise a cool, dark cupboard is fine.
Why does my dropper fill differently each time?
Squeeze technique and liquid viscosity vary; use the 1 mL mark rather than the bulb.
How many doses are in an Olivaro bottle?
About 30 at one dropper a day; roughly 15 at two.
