Normal people cannot take metformin for anti-aging. There is no research evidence that metformin has an anti-aging effect in normal people. Metformin is a hypoglycemic drug, this drug can improve the sensitivity of peripheral tissues to insulin, increase the utilization of glucose in peripheral tissues, inhibit hepatic glucose output, so as to achieve the effect of controlling blood sugar. This drug does not have anti-aging effects, so normal people should not use this drug for anti-aging. Normal people blindly eat metformin is a very dangerous thing, this drug has better efficacy in lowering blood sugar, normal people eat it may lead to lower blood sugar, may cause dizziness, fatigue and other symptoms of hypoglycemia, and may stimulate the gastrointestinal tract, causing nausea and vomiting, abdominal pain and diarrhea and other adverse reactions. Metformin should be used under the guidance of a professional doctor, and individuals should not use the drug blindly.
