Berberine is extracted from several plants and has become one of the more widely studied natural compounds for metabolic health, particularly around glucose handling.
Clinical research on berberine often uses considerably higher, multiple-daily doses; LipoJaro's 15 mg once-daily serving is a supportive amount within a broader formula, not a standalone berberine protocol.
It's the second-most-researched ingredient in this formula after cinnamon, by our read of the available literature.
Where it sits in the formula: part of LipoJaro's Blood Sugar Balance category, alongside Cinnamon Bark Extract 10:1, Prickly Pear Extract 4:1.
