Treatment of sarcopenia and glucose intolerance through mitochondrial activation by 5-aminolevulinic acid

Abstract Recently, sarcopenia has attracted attention as therapeutic target because it constitutes a risk factor for metabolic and cardiovascular diseases. We focused 5-aminolevulinic acid (ALA) which act as electron carriers in the mitochondrial electron transport system. The mice that received ALA...
