Hi anyone yang consume neurogain pb? Okay ke? Weeks brp start makan?

I took it when my foetus was 4months. Heard it helps on brain development. Hubby's friend recommended us as she said her kid is so smart and loves to read and became a fast learner. Not sure tho, just give a try ya. But my 3months baby now is so smart, fast learner, loves colourful books, a chatter box and response on music etc. Hopefully my hubby's friend is right! No harm trying, all the best!
