Where should pregnant mummies get their nutrients from?

I will try to have a balanced diet and eat all foods in moderation. However sometimes you might not be able to get all the required nutrition from the foods you eat. Hence, I'll drink 2 glasses of Similac Mum maternal milk daily just to ensure that I get all the necessary nutrients like calcium, folate, etc. This video might be helpful to you https://www.youtube.com/watch?v=1tm6bo87DbU
