Figure 1From: Caffeine extends life span, improves healthspan, and delays age-associated pathology in Caenorhabditis elegansCaffeine treatment results in a temperature-dependent life span extension in worms. Maintenance of worms in the presence of 5 mM or 7.5 mM caffeine throughout adult life increases life span at 15°C and 20°C, but not at 25°C.Back to article page
