Intermittent fasting is a permanent part of my life style. However, because of present circumstances, exercise for me has been limited which impacts sugar metabolism. However, Guava Tincture, and Guava Tea, have been invaluable for my need to keep glucose levels as low as possible to maintain an autophagic state. When I can get back to a normal exercise routine, I have no doubt that the efficacy of Guva will be even better!
