Panax ginseng is typically consumed in daily doses ranging from 200 to 400 mg, with the 400 mg dosage showing the most notable cognitive benefits.^[1] These doses refer to standardized ginseng extracts which contain around 4–10 % total ginsenosides (Panax ginseng’s primary bioactive compounds) and are taken once daily.

Higher doses (200–20,000 mg) have been used to target improvements in glucose and lipid profiles.^[2]

For trials focusing on erectile health and libido enhancement, Korean red ginseng extract is commonly administered at a dosage of 3 grams daily, divided into three doses of 1 gram each.^[3]
