A large number of substances in the combined anti-aging firewalls dietary regimen such as green tea extract, ashwagandah, curcumin, resveratrol, olive leaf extract and boswellia seratta are herbal in origin and contain multiple phytochemicals that have pluripotent antiaging effects. Caffeic acid is one such phytochemical, found naturally in coffee and many fruits and herbs.  Studies  show that caffeic acid and its phenethyl ester (CAPE) have multiple positive health and anti-aging impacts.  It has anti-oxidant, anti-inflammatory and anti-bacterial capabilities.  It inhibits the growth of tumor cells and is an inhibitor of nuclear factor kappa beta (NF-kappaB)(ref,ref,ref,ref). CAPE protects brain against oxidative stress and inflammation induced by diabetes in rats(ref).   

Thus, caffeic acid is part of the Anti-Aging Firewalls against Oxidative Damage, Chronic Inflammation, Susceptibility to Cancers and Programmed Epigenomic Changes for starters. It is probably best to get caffeic acid through drinking coffee, foods and herbal supplements rather than taking it directly as a supplement, however, since some earlier studies suggest that the substance may not be completely free of side effects. In the anti-aging firewalls supplements, caffeic acid is found in green tea extract, ginger extract, olive leaf extract and curcumin.  It is also found in cayenne pepper, celery, thyme, tarragon, black tea, cucumbers, apples, potatos, radishes, cabbage, grapefruit, bell peppers and of course coffee.  List of plants containing caffeic acid can be found here and, at the bottom, here.  

Caffeic acid is only one of a large list of phytochemicals with well-researched positive health and anti-aging capabilities.  I may feature others on this blog in the future.
