Vitamin B
B vitamins are essential to brain function, cell metabolism, and energy level. To maximize your intake of B vitamins, add a variety of non-processed foods to your diet, such as whole grains, beans, nuts, fruits, vegetables, and lean proteins.
The B vitamins help enzymes in our bodies do their jobs and are important for a wide range of cellular functions, like breaking down carbohydrates and transporting nutrients throughout the body.
