We just wanted fiber without the fake stuff

Cour started with some bad gas.

Enter psyllium husk.

We were blown away by what it did for our poops and overall wellbeing.

But every fiber on the shelf was loaded with sweeteners, fillers, or other questionable ingredients.

So we started mixing our own — just organic psyllium husk and real fruit.

And when our friends wanted to buy it, we knew we were onto something.

An ✕ does not mean that no study or potential benefit exists. Blood-sugar evidence relates primarily to the post-meal response. Comparisons reflect research on the primary fibers, not head-to-head clinical trials of the finished products.
