Daily Blood-Sugar Support · Adults 40+

Steady the curve.

Roughly 1 in 3 U.S. adults over 40 has measurable insulin resistance — and most don't know it yet. Grenov is a six-active blood-sugar-support formula built around berberine — the botanical with direct head-to-head clinical evidence against metformin — and dosed at the levels used in published research.

The Problem

The metabolic drift starts long before the diagnosis.

By 50, half of U.S. adults have measurable insulin resistance. Most never get the right blood test to find out, and almost none are told that the trajectory is modifiable until the diagnosis is already in hand.

The Approach

Six actives. Honest doses.

Most metabolic-health supplements bury 12 ingredients at fairy-dust doses. We do the opposite. Six actives, each at the dose used in the trials they're cited from. Berberine HCl as the cornerstone — head-to-head with metformin in published research. Cinnamon, chromium, alpha-lipoic acid, quercetin, and magnesium for complementary mechanisms.

1,000mg berberine HCl daily, split across two doses for the half-life. 500mg standardised cinnamon. 200µg chromium picolinate. 200mg alpha-lipoic acid. 100mg quercetin. 100mg magnesium glycinate. Every milligram on the label.
