HOW IT WORKS
Step 1
Floss like normal
Pick up an ARO Floss pick just like any other. Slide the vitamin-coated floss between your teeth — the same motion you already do every day.
Step 2
Vitamin release
As the floss moves through the tight spaces between your teeth, the vitamin coating is gently dislodged — depositing directly into the gingival crevice (the tiny gap between your tooth and gum).
Step 3
Your body absorbs
The vitamins absorb through the junctional epithelium — specialized tissue inside the gumline that creates both a systemic response (into your bloodstream) and a local mucosal response. It's a delivery route that bypasses the stomach entirely.
BENEFITS
Direct Delivery
Vitamins go straight into your system through the gum tissue — not your stomach, where absorption is hit and miss.
Zero Extra Time
You're already flossing. ARO Floss adds zero extra steps to your day — your vitamin routine is now built into something you do anyway.
No Pills to Swallow
There is nothing to choke down, just floss, and done. ARO Floss even comes in several delicious flavors — a cherry on top.
The Science
Beneath the Gumline
Most delivery routes — your cheeks, tongue, even your gut — are protected by thick, tightly sealed tissue designed to keep things out. The Junctional Epithelium (JE) is different. It’s a thin, naturally "leaky" tissue at the very base of the gingival sulcus — the tiny groove where your gum meets your tooth.
Think of it as the body's hidden gate. Unlike the thick barrier of your cheek lining, the JE has wide intercellular spaces and minimal tight junctions — making it exceptionally permeable to molecules placed directly into the sulcus.
When ARO Floss deposits vitamins into that groove, they absorb straight through the JE into richly vascularized connective tissue — entering your bloodstream without ever touching your stomach. Published in Nature Biomedical Engineering, 2026.
