When HbA1c or fasting glucose is high
A high A1c or fasting glucose is metabolic medicine. Food, training, sleep, and prescribed therapy come first. Berberine is the owner's marker-tied option, not a metformin replacement you start from a podcast.

- Coach, not doctor. Aaron Cuha is a coach, not a doctor. No medical credential is claimed for him, or for these pages. A number on a blood test is something to talk over with a doctor, not something to diagnose yourself with. Nothing here is a prescription, a plan to follow, or a reason to start or stop a medicine. Educational use only. This database summarizes published research and is not medical advice. Where a dose appears it is a record of what a trial or clinic ran, or what people describe doing, with its source attached. Nothing here is a recommendation for personal use.

What a coach checks first
One high morning is not a diagnosis. Repeat fasting glucose with A1c. Ask about fasting insulin if resistance is the question. Pregnancy and existing diabetes medicines are clinician gates.
What this does not mean
It does not mean berberine is metformin. Trial quality is mixed, most trials are small, and there is no outcome trial. It does not mean you stop a prescribed drug because a capsule moved a surrogate.
Markers to ask for on the blood test order
Supplements worth asking about, not orders
What people typically order
Ask for HbA1c, fasting glucose, and, if useful, fasting insulin on the same morning. A clinician-ordered panel or a coach-eligible bloodwork partner on /bloodwork/partners can collect those. The Archive does not.
When to stop
Name the marker before the bottle. Retest at about ninety days. If A1c and fasting glucose did not move, stop the berberine. Be loyal to the number.
