my doc told me to start taking elevit 3 months in advance.. elevit is the most expensive brand on the market and to be honest at the time i believed that they recieved some sort of benefit for the sale of elevit. however, my gyno also told me to start elevit as soon as you start ttc so i decided to take there advice. i have been ttc for 7 months now after m/c... and been on elevit for 3 months. its $70 for 100 tablets but i feel as though it cant hurt to have a storage of vitamins in your body as soon as you concieve. i also have a healthy diet, however, you need excess of these vitamins which we simply cant get from our food alone.
