One of my friends also gave me some 白蘭氏雞精 after I delivered my daughter. But, some BK moms told me that it may reduce milk production. Dare to try, I just put them in my closet and wait after I finish breastfeeding.
I recommend NOT to drink, I didn't drink everyday when I just delivered, but I think the supply did drop on the day I drunk. I just realized that will reduce milk production after 1 month, so i do think it affects, don't know if it is 心理作用 or not.
