Some experts recommend taking chasteberry on an empty stomach in the morning for maximal benefits. However, no studies have confirmed this finding. Various doses of chasteberry have been used in studies and practice. Traditional doses have ranged from 3.5-4.5 milligrams per day of dried extract to 600 milligrams three times per day of dried fruit. Other traditional dosing includes an aqueous alcoholic extract derived from 30-40 milligrams of dried fruit daily in 50-70% alcohol (v/v); 0.03-0.04 milliliters daily of fluid extract (1:1 gram per milliliter); 0.15-0.2 milliliter daily of tincture (1:5 gram per milliliter); 2.6-4.2 milligrams daily of a dried extract (9.5-11.5:1 w/w); or 0.5-1.0 grams of dried fruit taken three times daily.
