Europe deserves better supplements.
GumLab was founded in Sweden on a simple frustration: most of the industry asks you to trust it, without giving you a reason to.
I'm Aron Leijon, the founder of GumLab. I've spent alot of time thinking about how training, nutrition, and recovery actually work — and how rarely that translates into products you can actually verify, not just believe.
Look closely at most gummy supplements and you'll find the same pattern: full ingredient lists buried in a product photo instead of written out in plain text, lab reports with the important details blacked out, and formulas built more for the label than for the dose. It's not that the category is bad — it's that almost nothing in it is checkable. We wanted to build the opposite of that.
So GumLab is built around one non-negotiable rule: if we can't show it, we don't say it.
- —Every batch is assayed by an independent, EU-accredited laboratory — before it ships, not after a complaint.
- —The full Certificate of Analysis is published on the product page itself, unredacted.
- —Every ingredient, and its exact dose, is written out in plain text — never hidden in an image that can quietly change.
- —No proprietary blends. No dose you can't verify against the label.
But honesty isn't just something we put on a batch certificate — it's how we want to run this whole company. That means being upfront when something isn't perfect yet, not just when it's convenient. We're a new, small team building this from scratch, and we will get things wrong sometimes. What we promise is that we'll say so plainly when we do, and fix it, rather than quietly hoping no one notices.
That's also why your feedback matters more to us than almost anything else. We're not interested in five-star reviews we haven't earned — we'd rather hear the honest, slightly annoying feedback that actually makes the product better. Tell us the flavor's off, the dose feels wrong, the shipping was too slow, or the copy on this very page doesn't make sense. We read every message ourselves, and we'd genuinely rather know than not.
Because at the end of the day, none of this — the lab tests, the transparency, the packaging — means anything if it doesn't actually serve the people taking these gummies every morning, afternoon, or night. You're not a review count or a subscription number to us. You're the reason any of this is worth building carefully in the first place.
We make three gummies — Perform, Calm, Sleep — one for each part of the day. No powders, no pills, no guesswork. Just a product built to survive being checked, not just believed.
This is only the beginning, and we'd love for you to help shape where it goes. Welcome to GumLab.
