Vitamin B1, also known as thiamin, is the very important nutrient during pregnancy. It participates in the fat formation and helps amino acids to work properly.

In addition, thiamin regulates the nervous system. The lack of vitamin B1 causes nausea, fatigue and muscular weakness. Thiamin raises the energy level in tissues and cells. That's why this vitamin is very important for pregnant women.

Food rich in thiamin include whole grains, rice, pasta, egg, beans, nuts, berries and fortified food.
