About Us

Built for the people who read the labels.

Grenov wasn't built for people who want to feel optimistic about their health. It was built for people who want to read the research, look at the actual doses, and decide on evidence — not on marketing.

Our Story

A formula that survives a careful read.

The metabolic-health supplement aisle is unusually marketing-heavy. Berberine in particular has become a fashionable ingredient, included at fractional doses in dozens of "metabolic" formulas where the label is more impressive than the contents. We didn't want to add to that.

So we did the unglamorous thing. We read the trials behind every ingredient we considered. We looked at the head-to-head studies of berberine against metformin. We checked the cinnamon meta-analyses. We looked at chromium's regulatory recognition. And we built a six-active formula at the doses that produced the headline results — not the doses that would let us claim the ingredient on the front of the box.

The result is a small, clear product made for people who'd rather understand than be sold to.

Grenov
What We Believe

Three rules we won't break.

1

Trial-equivalent doses, or nothing.

Every active is at the dose used in the published research we cite. If we can't deliver a clinical dose, the ingredient isn't in the formula.

2

No proprietary blends.

Every milligram is stated on the label. No hidden quantities, no marketing-friendly opacity.

3

Show the work.

Every batch is third-party tested for active-compound content (specifically the berberine HCl content) before release. The COA is available on request.

Where it's made

A GMP-certified U.S. facility.

Grenov is manufactured in a GMP-certified facility in the United States, in deliberately small batches. Each lot is third-party tested for active-compound content, heavy metals, and microbial purity before release.

Berberine HCl is sourced from a Berberis aristata supplier in Northern India that has supplied pharmaceutical-grade botanical ingredients for over a decade. Standardisation and purity are verified at the ingredient level and again at the finished-product level.
