Cara Kerja Metformin

🔬

AMPK Activation

Activates the cellular energy sensor AMPK. Mimics caloric restriction signaling. Reduces hepatic glucose production

🔬

mTOR Inhibition

Indirectly inhibits mTORC1 via AMPK. Promotes autophagy — cellular cleanup. Reduces protein synthesis — longevity signal

🎯

Metabolic Effects

Improves insulin sensitivity. Lowers fasting glucose and HbA1c. Mild reduction in body weight (1–3 kg)

Data Kunci

Pasien yang saat ini menggunakan metformin di seluruh dunia — obat diabetes yang paling banyak diresepkan.

Dosis yang sedang diuji dalam uji klinis manusia bersejarah 'Targeting Aging with Metformin'.

Proporsi pengguna metformin jangka panjang dengan defisiensi B12 tanpa suplementasi.

Ikhtisar Protokol Metformin

Pantau: Kadar B12 tahunan, eGFR, HbA1c. Hindari pada hari latihan fisik berat (kontroversial) dan hentikan sebelum pencitraan kontras. Gunakan jenis extended-release untuk meminimalkan efek samping pencernaan.

Lini Masa Riset Umur Panjang Metformin

Metformin pertama kali dideskripsikan di Prancis. Digunakan untuk T2D di Eropa sejak 1958.

Makalah NEJM: penderita diabetes yang mengonsumsi metformin hidup lebih lama dibanding non-diabetes yang setara — sinyal umur panjang yang bersejarah.

FDA menyetujui protokol uji klinis TAME (Targeting Aging with Metformin) — uji penuaan pertama yang disetujui FDA.

Uji klinis TAME aktif merekrut ~3.000 orang dewasa sehat usia 65–79 tahun. Hasil diharapkan keluar pada 2027.

FAQ Protokol Vital

🛡️

Why are healthy people taking metformin for longevity?

Metformin, the most prescribed diabetes drug in the world, has attracted longevity interest because of its AMPK activation (same pathway as caloric restriction), mTOR inhibition, and observational dat

💉

What is the metformin longevity dose?

For longevity purposes (off-label), physicians typically prescribe 500–1000 mg/day, often taken at night or with meals to minimize GI side effects. The TAME trial uses 1500 mg/day. Diabetic doses go u

🔬

Does metformin interfere with exercise adaptations?

This is a genuine controversy. A 2023 study showed high-dose metformin blunted some exercise adaptations (VO2max gains) in older adults. However, lower doses and specific timing (avoiding pre-workout

🔬

Is metformin safe for non-diabetics?

Metformin has a very long safety record with billions of patient-years of use in diabetics. The primary risk in non-diabetics is hypoglycemia (rare at low doses) and vitamin B12 depletion with long-te
