Interaction Warning
CRITICAL: If you are taking metformin, insulin, or sulfonylureas (e.g., gliclazide, glipizide) for blood sugar control, do NOT start berberine or chromium without consulting your GP first. Both supplements lower blood sugar, and combining them with diabetes medications significantly increases the risk of dangerous hypoglycemia. Your doctor may need to adjust your medication dose. If you take a statin (e.g., atorvastatin, simvastatin), berberine may increase statin levels via CYP3A4 inhibition — discuss with your GP. If you take levothyroxine for thyroid health, take chromium at least 3–4 hours apart to avoid reduced absorption. If you're pregnant or breastfeeding, avoid berberine — it crosses the placenta and passes into breast milk.
Berberine is the gold-standard supplement for blood sugar and metabolic health.

Start with 500mg once daily with a meal for 1–2 weeks to minimise GI side effects, then increase to 500mg with meals 2–3 times daily (1500mg total). This split dosing maintains steady blood levels and targets postprandial glucose spikes more effectively than a single dose.

Take 200–1000 mcg daily with meals. Start at 200 mcg and increase to 1000 mcg if needed — higher doses showed stronger HbA1c reductions in clinical trials. Can be taken as a single dose or split across meals. Chromium picolinate is superior to chromium chloride for absorption.
