Chlorogenic Acid

Last Updated: September 28 2022

Chlorogenic acid is found in coffee mostly and a lot of plant compounds; it holds promise in many aspects of health and cognition similar to bioflavonoids and shares some effects similar to caffeine but less potent. May decrease the absorption of dietary carbohydrate.

Chlorogenic Acid is most often used for


Chlorogenic acid is a phytochemical found in coffee and coffee beans. It has been touted as being able to reduce blood sugar levels and potentially exert an anti-diabetic effect. It has also been implicated in weight loss and exerting an anti-obesity effect, but that is insofar correlation and not necessarily due to chlorogenic acid.

It can be beneficial to supplement, although doses found in food sources are enough for a long-term preventative (anti-diabetic) measure.

What else is Chlorogenic Acid known as?
Note that Chlorogenic Acid is also known as:
  • Coffee bean extract
  • 5-O-caffeoylquinic acid
  • 3-O-caffeoylquinic acid Green coffee extract
Chlorogenic Acid should not be confused with:
  • Chlorine
  • Corosolic Acid
Dosage information

Supplemental chlorogenic acid appears to have benefit in the range of 120-300mg oral intake, with higher doses still possibly beneficial (not really tested sufficiently). These doses appear to benefit blood pressure and circulation mostly.

This dose seems to be low enough that moderate to high doses of plants with a rich chlorogenic acid content may confer the benefits listed on this page, this most notably includes green coffee extract.
