Chasteberry from Revive MD stimulates natural progesterone production by acting on the pituitary gland, thereby balancing hormonal levels, particularly in conditions where progesterone is low. It also increases progesterone availability in the bloodstream and reduces its breakdown, maintaining higher levels for longer periods. Additionally, it lowers prolactin levels, indirectly supporting progesterone production by reducing prolactin's inhibitory effects.

By modulating both progesterone and prolactin levels, Chasteberry helps achieve a more balanced hormonal state, beneficial for conditions like PMS, menstrual irregularities, and possibly fertility issues. Clinical evidence and usage support its efficacy in hormonal regulation, making it a common choice in herbal medicine and integrative therapies.
