Vitamin A drops are used “for regenerative treatment of acute or chronically damaged nasal mucous membranes, for instance in the overuse of certain nasal sprays, for dry mucous membranes during winter months or where there is irritation…”
Vitamin A is thought to support the recovery of the delicate olfactory tissues that can help to restore the sense of smell in cases of post-viral smell loss, although doctors are still waiting for better evidence of the effectiveness.
The first study in Germany in 2017 found Vitamin A drops “beneficial”, however the sample size was small which is why more studies are needed. A research study at the University of East Anglia was initiated in 2021 to carry out further trials and we are awaiting results of this study.

Generally speaking, if you find that the nose oil is dripping down the back of your throat when your head is upright, you have used too much. You only need enough to coat the mucous membranes. It can be hard to judge how many drops you are using, so look at the pipette and make sure you don’t have it fully loaded before you apply.
Vitamin A can be toxic in high doses (much much higher than recommended here). Please do not over use as you will not experience any further benefit. You should use for one month, and then stop for at least a month.
