Peptides kept coming up in what I read about health and longevity. I’m into that world, though not as a fanatic, so I looked closer. Most of the peptides people take for recovery are injected, and the research behind them is mostly in animals, with very little in people. I wasn’t going to inject something I couldn’t check, and I didn’t see why anyone else should have to.
So I went looking for one that could go in food and had been studied in humans. Most can’t go in food at all. The one I found comes from fava bean protein, and it was tested in placebo-controlled human trials. It supports muscle strength and recovery.

Getting it into something you’d want to drink every day took longer. Protein shakes are crowded with big claims, and a cold, lightly sparkling can felt like a better, more refreshing alternative. Our first samples were too sweet. We worked with our team, including a former head of global R&D at a major beverage company, and came out with four flavors we like: Yuzu Lime, Mixed Berry, Mango Passionfruit and Blood Orange. All four are kept low on sweetness, with no artificial colors, flavors or sweeteners.
Spry is for people who train to stay capable, whether that’s a Pilates class, a gym session or a run club, at 25 or at 50. I’d like it to be the company that took studied peptides out of the vial and into everyday life. The first run is planned to ship in December, and founding members get it first.
Strong is a habit.
