For general health needs, multiple daily servings of fruits and vegetables can provide adequate amounts of apigenin, which is estimated to be less than 5 mg/day.^[1][2] Apigenin is sufficiently bioavailable through such dietary sources.^[2] In contrast, apigenin that’s been isolated from its source is rarely stable enough to be absorbed by the body.^[3] Because isolated apigenin is so unstable, it is unlikely that it will be available in supplement form.^[4][5]
