Also known as Riboflavin, vitamin B2 assists in cell function, growth and energy production and is found naturally in a balanced diet. As such, dairy products, eggs, grains, and green vegetables are sources of vitamin B2, though meat is required to ensure adequate consumption. Though most healthy people are not deficient in vitamin B2, those on a diet may need to add additional supplement to gain a sufficient amount of the vitamin.
How it Works
According to Stanford University researchers, vitamin B2 works with coenzymes FAD and FMN, both of which assist in the function of the electron transport chain -- a process that creates energy for the body. This process includes FAD and FMN carrying, transforming and transferring electrons throughout the body. When consumed, vitamin B2 alters these two enzymes, enabling them to perform their energy-producing role in our body. Without vitamin B2, the body can lose energy if the deficiency is severe enough.
Vitamin B2 and Thyroid Regulation
Vitamin B2 can positively affect weight control in a number of ways, including regulating the thyroid. The thyroid is a gland that regulates your metabolism, energy use and weight. As such, a healthy thyroid will help ensure that your weight remains stable and that you are able to engage in the exercise necessary to lose or maintain your current weight. The Environmental Illness Resource notes that vitamin B2 helps in this way by assisting in the production of T4, the primary hormone produced by the thyroid. A vitamin B2 deficiency can contribute to problems of underactive thyroid, ultimately leading to weight gain and other health problems.
Vitamin B2 and Metabolism
Vitamin B2 aids in the production of energy by helping to metabolize carbohydrates, fats and proteins, a process that leads to storing energy in muscles. According to researchers at Stanford University´s Huntington Outreach Project for Education, B2 assists in this process through its role in the electron transport chain, which ultimately leads to energy production. Your metabolism impacts the rate, at which you lose weight by regulating how your body creates and burns energy. Consequently, people with lower metabolism can burn calories at a slower pace than those with a higher metabolism.
Considerations
Vitamin B2 can interact with medications prescribed for respiratory, bladder, or stomach disorders and cause an increase in vitamin B2 absorption into the body. However, the effects of increased B2 intake are not known to be detrimental. In contrast, anti-depressants can decrease the amount of B2 in the body, so supplements may be necessary.
Identification of B2 Deficiency
Deficiency in vitamin B2 can cause changes to a person'a physical appearance, particularly in the lips, tongue and eyes. Cracks or sores may become present at the corner of the mouth and eyes may become sensitive to light and red. Vitamin B2 deficient individuals may also experience fatigue or dizziness, as a result of poor metabolism or lack of energy.
