Is Ensure Life Milk safe for pregnancy?

Hi mummies, I’m currently in my 8th week. I was given ensure life milk to drink by my concerned family as I couldn’t stomach food very well. However this morning I saw that vitamin A was included in the milk and I vaguely recalled too much vitamin A is harmful for the baby? I’m not quite sure if it’s safe for me to continue ensure life milk? Your advice pls! Thank you.
