Riboflavin is Vitamin B2 and is needed for creating energy by breaking down fats, carbohydrates, and proteins. Vitamin B2 (Riboflavin) is also used for building red blood cells. It is water soluble meaning that your body can't store it and is only available through food.

B2 is available through a mixed and varied diet including egg yolks, red meat, salmon, tuna, soybeans, almonds, and wheat.

Vitamin B2 deficiency symptoms are as follows: fatigue, swollen throat, blurred vision, and depression.

This vitamin is great for reducing oxidative stress, regulating thyroid activity, and inflammation of nerves which can cause migraines.  Riboflavin is also very important for fetal growth and development so pregnant people are advised to take a B2 supplement.
