We took saffron-based stress support to another level — because that's what it takes to actually feel calmer.
Daily stress support needed real testing. We did it.
Most stress and mood supplements aren't tested in real life — they're sold on vibes and pharmacy aisle real estate. We weren't satisfied with the existing data around saffron-based stress support, so we built SF3® around the clinical research that actually exists.
Today, every SF3® batch ships with third-party testing on identity, purity, and active levels. Our formula isn't guessing with saffron — it pulls from over a decade of published trials so you can trust that what's on the label is what's in the gummy.
Guaranteed results, or your money back.
We're confident in the formula because it's built on saffron clinical research — the same active that's been shown to support mood and stress markers in published studies. If SF3® doesn't work for you in 30 days, we'll refund you.
With SF3®, feel calmer in 30 days — or your money back.
SF3® uses standardized saffron extract dosed at the level used in published mood-support research — not a token sprinkle. Every gummy delivers the same active load, so the routine stays consistent day after day.
Saffron is one of the most adulterated spices on Earth. We work directly with verified growers and require certificate-of-analysis on every lot before it touches the formula.
Many stress supplements make baseless claims. We back ours with real research.
Our formula references over a decade of peer-reviewed clinical studies on saffron, L-theanine, and rhodiola — not in-house marketing claims. Every active in SF3® is tied to published research on mood, stress, or sleep markers.

An informed hypothesis
SF3® starts each formulation cycle with a systematic review of saffron, L-theanine, and rhodiola clinical literature — then sets a target outcome before touching the formula.
Real-world trials.
Every formula iteration is tested on real users over a 30-day window with structured questionnaires on mood, stress, sleep, and focus markers — not just self-reported vibes.
Analyze and iterate.
At the end of each trial we analyze the data, hold the formula to the published research, and only roll the next batch if it clears both bars. Product development is continuous.
We're devoted to continual improvement.
Our process is driven by two questions: why, and how. We're constantly re-evaluating every decision we've made, and asking new questions in search of better outcomes for the people who trust SF3®.
Here are the latest questions that drive what we do:
Modern life loads the nervous system with constant stress signals. SF3® combines saffron (mood support), L-theanine (calm focus), rhodiola (stress adaptation), and B vitamins (nervous system support) to address daily stress recovery from multiple angles.
Saffron has been studied in over a decade of peer-reviewed mood and stress research. Standardized saffron extract is one of the few plant actives with consistent clinical signals on mood markers — which is why it anchors SF3®.
We tested both. The daily-use compliance on gummies was significantly higher in our internal trials — and active levels are matched 1:1 with the capsule format we benchmarked against.
