| Side Effects | Berberine has a favorable overall safety profile across tested doses (typically 500-1,500 mg/day in clinical trials) and durations (typically 8-24 weeks in most trials, up to 12 months in longer studies). The most common side effects relate to the… | Metformin has a well-characterized side effect profile dominated by GI tolerability issues that are usually manageable and a rare but serious lactic acidosis risk that warrants attention in specific clinical contexts. Common GI side effects affect 20-30% of… |

Metformin is a metabolic that metformin's molecular mechanism of action has been progressively elucidated over decades and now involves multiple overlapping pathways, though which pathway dominates in any given…. The two differ in mechanism, half-life (not reported vs not reported), and typical dose range.
Which has the longer half-life, Berberine or Metformin?
Berberine has a half-life of not reported. Metformin has a half-life of not reported. Longer half-lives generally mean less frequent dosing but slower on/off kinetics.
Can you stack Berberine and Metformin?
Stacking depends on mechanism overlap, safety profile, and goals. Berberine and Metformin should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data. Use the BodyHackGuide stack builder for a structured review before combining research compounds.
