AMPK activation & cellular fuel sensing
One of 4 mechanistic pathways to 📉 Metabolic health & insulin sensitivity · 12 options
AMPK is the switch that flips when cellular energy is low — it increases glucose uptake, fat oxidation and mitochondrial biogenesis while switching off storage. Exercise and fasting activate it, and so does everything in this list.
Fasting insulin is the earliest signal and almost nobody orders it — glucose stays normal for years while insulin climbs to keep it there. Note that metformin depletes B12, which is why it is on this list.

What engages this pathway
Ordered by how directly each one acts on the mechanism above — never by how much trial evidence exists. Each links to its full breakdown with dosing, half-life and vendor.
💉 Metformin
Complex-I inhibition raises AMP:ATP and activates AMPK; hepatic glucose output falls. The most-studied metabolic drug in existence. It also blunts some exercise adaptations and depletes B12, both worth knowing.
🧬 Berberine
AMPK activation through a similar mild complex-I inhibition. Head-to-head trials against metformin show comparable glycaemic effect, with better lipid results in some.
🧬 Dihydroberberine
Reduced form with roughly five-fold better absorption, so lower doses reach the same exposure with less GI disruption.
💉 MOTS-c
AMPK activation from a mitochondrially-encoded peptide, with insulin-sensitising effects in aged mice.
💉 AICAR
The canonical direct AMPK activator; the human obstacle is entirely pharmacokinetic.
💉 ATX-304
A drug-like pan-AMPK activator built to solve that problem. Early human safety data exists.
💉 5-Amino-1MQ
NNMT inhibition preserves the nicotinamide already in the salvage pathway rather than adding precursor — so adipocyte NAD+ and SIRT1 activity should rise without the methyl-group cost of precursor loading. Mouse-stage; the human trial has not been run.
🧬 Alpha Lipoic Acid
Activates AMPK in muscle and improves insulin sensitivity; strong trial evidence in diabetic neuropathy specifically.
🧬 Green Tea (EGCG)
EGCG activates AMPK and inhibits alpha-amylase; modest but consistent metabolic effects.
🧬 Resveratrol
SIRT1 and AMPK activation in preclinical work; human metabolic trials have been largely disappointing.
🧬 Pterostilbene
Better-absorbed analog; inherits both the mechanism and the uncertainty.
🧬 Urolithin A
Mitophagy improves mitochondrial quality, which improves substrate handling.

Frequently asked questions
AMPK is the switch that flips when cellular energy is low — it increases glucose uptake, fat oxidation and mitochondrial biogenesis while switching off storage. Exercise and fasting activate it, and so does everything in this list.
12 options are mapped to this pathway in the Vault, including Metformin, Berberine, Dihydroberberine, MOTS-c. They are grouped by the mechanism they act through rather than ranked by how much trial evidence exists — 5 carry clinical validation and 7 are mechanistic predictions.
Fasting insulin is the earliest signal and almost nobody orders it — glucose stays normal for years while insulin climbs to keep it there. Note that metformin depletes B12, which is why it is on this list. The markers worth checking are Fasting Insulin, HbA1c (Hemoglobin A1c), C-Peptide, Serum, Comprehensive Metabolic Panel (CMP).
Unproven is not the same as ineffective. Of the 12 options on this pathway, 5 have clinical validation and 7 are graded theoretical — meaning the mechanism is sound but the specific human trial has not been run, which is true of a great deal of what works in this space. Nothing on this page is ordered by evidence tier, because sorting by trial count would bury the compounds you came looking for.
