Everything About Vitamin B2: A Comprehensive Guide and Best Practices
Overview of Vitamin B2 (Riboflavin)
Basic Introduction to Vitamin B2
Vitamin B2, also known as riboflavin, is a water-soluble B vitamin that is essential for the normal physiological functions of the human body. It is involved in various metabolic processes, playing a key role particularly in energy production and cell repair. Riboflavin is converted in the body into its active forms, namely flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), both of which serve as coenzymes for various enzymes, facilitating redox reactions and other biochemical reactions.
Physiological Functions of Vitamin B2
Vitamin B2 has multiple physiological functions in the human body, mainly including:
- Energy Metabolism: Involved in the metabolism of carbohydrates, fats, and proteins, helping to convert food into energy.
- Antioxidant Effects: As an antioxidant, vitamin B2 helps neutralize free radicals, protecting cells from oxidative damage.
- Cell Repair and Growth: Promotes normal cell proliferation and repair, maintaining tissue health.
- Red Blood Cell Production: Involved in the production of red blood cells, preventing anemia.
- Nervous System Health: Supports the normal functioning of the nervous system, maintaining the stability of nerve conduction.
Sources and Foods of Vitamin B2
Vitamin B2 is widely found in various foods, and here are some major food sources rich in riboflavin:

Health Benefits of Vitamin B2
Energy Metabolism and Vitamin B2
Vitamin B2 plays a central role in energy metabolism. It acts as a coenzyme involved in various metabolic pathways, helping to convert carbohydrates, fats, and proteins into usable energy. Specifically, after being converted into FAD and FMN, these two coenzymes participate in the electron transport chain, facilitating cellular respiration and ATP production. Additionally, vitamin B2 also plays a role in the β-oxidation of fatty acids, helping to break down fatty acids for energy.
Antioxidant Effects and Cellular Protection
Vitamin B2 has significant antioxidant properties, effectively neutralizing free radicals in the body and reducing oxidative stress on cells. This characteristic gives riboflavin potential in preventing various chronic diseases, such as cardiovascular diseases, cancer, and neurodegenerative diseases. The antioxidant effect also helps delay cellular aging, maintaining the health of the skin and other tissues.
Health of Skin, Eyes, and Nervous System
Vitamin B2 has an important impact on the health of the skin, eyes, and nervous system. It helps maintain normal skin growth and repair, preventing skin inflammation and other skin issues. For the eyes, riboflavin can reduce eye fatigue, protect the retina from light damage, and lower the risk of cataracts. In terms of the nervous system, vitamin B2 supports the stability of nerve conduction, reducing the occurrence of nervous system diseases.
Vitamin B2 and Chronic Disease Prevention
Adequate intake of vitamin B2 is closely related to the prevention of various chronic diseases. Research shows that the antioxidant and anti-inflammatory effects of riboflavin help reduce the risk of cardiovascular diseases. Additionally, vitamin B2 has also shown potential in cancer prevention, as it can reduce DNA damage and abnormal cell proliferation. For diabetic patients, vitamin B2 helps improve glucose metabolism and enhance insulin sensitivity.
