GLP-1 receptor agonists + Berberine contraindicated?

Berberine reduces blood sugar, so what would be the point of pairing it with reta?

Open to testing the same stack at 1200 mg berberine daily. Tend to respond strongly to compounds and track sides closely. Planning a week to clear other items first. Skip breakfast anyway and can run it for 12-16 weeks. Would a continuous glucose monitor be useful?

Haven’t tried the exact pair. Berberine itself is well researched and effective. Would go ahead if desired but with caveats: slower gastric emptying from reta could keep berberine in the gut longer and raise absorption; both can cause GI upset; berberine alone can lower glucose and may inhibit DPP-IV, adding to incretin action. Would begin at 500 mg daily and titrate while watching response.

Retatrutide seems to perform the strongest.

Have used reta plus berberine for roughly two months without issues. Doses included 2.1 mg reta twice weekly with 1200 mg berberine, then a tirz/reta mix, then back to reta alone. Berberine taken in the morning with other supplements or occasionally at night after high sugar intake. Pre-diabetic for years; A1C moved from 6.1 to 5.7 then 5.4. Fasting insulin remains elevated. Liver enzymes normalized for the first time. Some improvement likely from timing bloodwork away from training.

Used 1200 mg berberine daily for years with A1C near 6.1 and signs of fatty liver. Added 8 mg reta in February; lost 95 lb with no sides. Liver tests normalized, A1C now near 4.5. Stopped blood pressure medication but still need CPAP. Lipids also normalized so planning to reduce statin.

Using a slow-release dihydroberberine at 150 mg twice daily plus 500 mg berberine with dinner alongside 4 mg reta every five days and nightly growth hormone. Diet is moderate in carbs. No hypoglycemia episodes. Morning fasting glucose consistently 82-94 with excellent A1C.

Planning to restart berberine this week at a reduced dose of 500 mg with dinner and monitor how it feels.

On reta since May and added berberine about a month ago after increasing growth hormone to help keep insulin sensitivity. Glucose reading was 70 on reta alone in July; one week after starting berberine it was 59. Not certain berberine caused the drop and no clear hypo symptoms, though occasional light-headedness on standing has always occurred.

Already on berberine before starting reta. No obvious problems at 500 mg in the evening. Current reta is 750 mcg three times weekly and planning to lower the dose after reaching goal weight to focus on gym progress.

Hypoglycemia risk applies mainly to those using injected insulin or drugs that force excessive insulin release from the pancreas. Non-diabetics on those same drugs would face identical risk. General advice to diabetics often gets simplified for convenience even when the actual mechanism is narrower.

Checking in on how the combination turned out. A couple weeks into reta on a carnivore diet, fasting glucose appears higher than with diet alone. Considering berberine to bring glucose down and restore ketone levels that also dropped on reta.

Agree the background is metabolically impaired but improving. Glucose was well controlled on carnivore before reta, just no weight loss. Appetite suppression appeared early. Slight sides at 0.75 mg split dosing led to staying at that level for now. One carb test day did not change how long glucose stayed elevated. Slowed motility might extend the period of insulin and glucose activity.

Reminds me of older very-low-protein approaches using rice as the staple.
