How they're made
Made as a film.
Tested by the lot.
FlexFlash™ is our name for the patent-pending way every FlexRX strip is made: a single-layer film, cast to a fixed amount, sealed in its own foil packet, and tested by an independent lab before it ships.
What is in the film
Four things,
and no more.
- Pullulan film
- A neutral polysaccharide base, cast in a single thin layer. It is what makes the strip a strip.
- The actives
- Added by weight into the film before it is cast, so the amount in every strip is set at manufacture.
- Flavour
- One flavour per formula.
- Nothing else
- No dyes for the sake of colour and no fillers.
Testing
We do not grade our own work.
Every production lot is sent to an independent laboratory, which confirms the identity and purity of what is in it. The result is tied to the lot number printed on your carton, so the box in your hand traces back to a specific test rather than to a general promise. Nothing ships on an in-house result alone.
Manufacturing runs in a cGMP facility in the United States. If you want the paperwork for the lot you were sent, ask us and we will send it.
