Overview
An isoquinoline alkaloid that activates AMPK - the same pathway as metformin. Liposomal delivery overcomes berberine's poor bioavailability, making it one of the most powerful natural interventions for glucose management, lipid control, and metabolic longevity. Often called 'nature's metformin'.
Summary
A methyl donor derived from beets that supports the methylation cycle, reduces homocysteine, and helps maintain methyl group availability when supplementing NAD+ precursors like NMN or NR.
