I'm 32 weeks along on my second pregnancy. Does any one here know when you can start taking raspberry leaf tablets and how much you should take. I seem to remember last time it was about 36 weeks onward but I was taking the tea. Decided cannot be faffed this time with the insipid tea and have opted for the tablets instead. The blurb says that each tablet contains 640 mg (rubus idaeus) (from 213 mg of 3:1 estract) No idea what that means or how strong they are.
