Evidence-Based Stack
Metabolic Stack
Four supplements with RCT evidence on blood sugar, triglycerides, or insulin sensitivity — the real metabolic risk markers.
Metabolic-health marketing ranges from legitimate (berberine) to marketing noise (chromium megadoses). This stack focuses on compounds with actual RCT evidence on glucose, HbA1c, or triglycerides in prediabetic or metabolic-syndrome populations. Berberine is the standout — AMPK activation with head-to-head evidence against metformin. Alpha-lipoic acid has specific diabetic-neuropathy evidence. Omega-3 at 2-3 g/day meaningfully reduces triglycerides. Cinnamon is an accessory, not a primary lever. Skipped: chromium (mostly ineffective at supplement doses), bitter melon (weak evidence in human trials), apple cider vinegar (minimal glucose effect).
What's in it
AMPK activator — comparable to metformin in newly-diagnosed type 2 diabetics in multiple head-to-heads.
Dose: 500 mg 2-3x/day with meals (short half-life requires split dosing)
Full Berberine profile →Reduces triglycerides substantially at 2-3 g/day EPA+DHA. The only consistently-effective natural triglyceride lowerer.
Dose: 2-3 g combined EPA+DHA/day with food
Full Omega-3 Fatty Acids profile →Antioxidant + insulin sensitizer. Best-evidenced for diabetic neuropathy pain; modest glycemic effect.
Dose: 300-600 mg/day split, on empty stomach
Full Alpha-Lipoic Acid (ALA) profile →Modest fasting-glucose effect. Ceylon specifically — cassia cinnamon contains liver-stressing coumarin.
Dose: 1-3 g/day
Full Ceylon Cinnamon Bark Powder profile →How to take it
Berberine dominates this stack — split doses are critical because of the short half-life. Omega-3 pairs well with any lipid-lowering strategy. Alpha-lipoic acid daily, morning. Cinnamon is accessory — not worth a dedicated regimen on its own. Monitor fasting glucose and HbA1c over 3-month cycles; this is a measurable stack.
Cautions
Berberine + diabetes medications (metformin, sulfonylureas, insulin) can cause additive hypoglycemia — monitor closely and coordinate with prescriber. Alpha-lipoic acid can lower blood sugar in diabetics. Omega-3 has mild anticoagulant effect. Cassia cinnamon (the cheap kind) has coumarin-related liver concerns at high chronic doses — Ceylon is the safer choice.
