The Hydration Science of Natural Salts
The New Frontier of Hygiene
How FEND Works
Fend is the only nasal mist comprised of calcium chloride at a salt concentration similar to sea salts, and with a droplet size designed to deposit not only in your nose, but in your sinuses, and in your windpipe, too.
Once deposited, FEND salts draw water from surrounding tissue to keep your airways moist and cleaning the air for up to 6 hours. Over 7 peer-reviewed publications in leading science journals.
A Trace of Magnesium
Magnesium is an important cation in your airways that is often lower in concentration than it should be, since our bodies are often low in magnesium levels.
FEND has a very small amount of magnesium, just enough to add to top off your airway magnesium levels. Like calcium, magnesium stays longer in your airways than sodium (the cation of normal saline), since it gets into our tissues by going around airway cells, and not through them.
"Hydrating the airways daily is the missing link in what we’ve considered till now effective whole-body hydration."

David’s work on airway hygiene spans decades – beginning shortly after his pioneering work on inhaled insulin, to his scientific work today that explores immediate and long-term benefits to airway hydration.
