The short version

An alpha-glucosidase inhibitor — slows carbohydrate absorption; ITP program: lifespan extension in male mice (+22%); geroprotector candidate.

Identity & type

Molecular type
mali molekul
Origin
An alpha-glucosidase inhibitor — slows carbohydrate absorption; ITP program: lifespan extension in male mice (+22%); geroprotector candidate.

Mechanism of action

Blocks intestinal α-glucosidase → smaller glucose spikes; secondary metabolic effects.

Dosing & routes

Official / clinical context

Approved drug — indications, dosing and warnings are defined by the official label. 25–100 mg with meals 3×/day.

Regulator-approved labeling and published study designs — never a recommendation.

Community-reported practice

25–100 mg with meals 3×/day. In diabetics: steadier post-meal glucose; the longevity community rarely uses it due to gas/bloating.

Unverified self-reports. Not medical advice. Not endorsement.

Expected effects (community)

In diabetics: steadier post-meal glucose; the longevity community rarely uses it due to gas/bloating.

Protocol — official vs community

Official / label

Approved for T2D (25–100 mg TID with first bite of each meal). ITP mouse lifespan data drives longevity interest.

  1. 01Start 25 mg TID, titrate to 50–100 mg TID by postprandial glucose

Duration: Continuous.

Alpha-glucosidase inhibitor — flattens the glucose spike at the cost of flatulence (the price of mechanism).

Community (anecdotal)

25–50 mg with the largest-carb meals only (selective use) or TID per label.

Cycle:
Continuous.
Break:
None.

The ITP (Interventions Testing Program) lifespan signal is the strongest animal-rationale in the codex for a prescription drug.

Human evidence

ITP longevity data; standard antidiabetic in Asia.

Preclinical evidence

The preclinical phase was completed and submitted to regulators as part of registration; pharmacology and toxicology details are part of the official label.

Known risks

  • Bloating, gas (common).characterized

Teal: characterized in clinical/labeling contexts. Amber: theoretical or reported outside controlled settings.

Unknowns & evidence gaps

  • Real-world data outside controlled trials
