Timing
Together with food.
How it works
DIM modulates CYP1A1/CYP1B1 to favour 2-hydroxyestrone production; zinc is a cofactor in aromatase enzyme regulation.
DIM (from cruciferous vegetables) promotes the 2-hydroxy oestrogen pathway, considered less proliferative. Zinc plays a role in regulating the aromatase enzyme that converts testosterone to oestrogen. Clinical evidence for the specific pairing is limited.
What to do
Take together with food. This stack is popular in men's hormone protocols but also used by women for oestrogen balance. DIM can cause GI upset on an empty stomach.
