I am looking for calculation "energy density in kJ" of chlorogenic acid. But i cant find its caloric output in human body after injection. Please provide value with references. Thank you.
I don't know if it's known. Someone needs to study its metabolism in order to know the answer.
According to this reference the daily intake for coffee drinkers is up to 1 g and only a third of this would be absorbed, therefore I would say it's not relevant amount of energy.
