Vitamin B2, often known as riboflavin, is a water-soluble vitamin that is essential for human health in a variety of ways. Riboflavin, as an essential component, participates in critical metabolic activities, such as the conversion of carbs, lipids, and proteins into energy. Its activity as a coenzyme, specifically in the creation of flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN), guarantees that cellular respiration and energy generation within the mitochondria run smoothly. Riboflavin is not retained in the body due to its water-soluble nature, emphasising the significance of a constant dietary intake or supplementation to meet daily requirements and maintain general well-being.

food sources of vitamin b2: eggs, red meat, broccoli, nuts and seeds, legumes.


Vitamin B2, commonly known as riboflavin, is an essential component that performs a variety of roles in human health. Riboflavin’s relevance in cell health, energy production, and skin upkeep is supported by scientific studies, making it a critical component of general well-being.

  • Cell Health: Riboflavin’s impact on cell health is supported by a large body of scientific evidence. Its key role in cellular metabolism, notably in the metabolism of carbs, lipids, and proteins, has been established through research. A study published in the “Journal of Biological Chemistry” (2017) underlined the importance of riboflavin in cellular energy production by establishing its role in the synthesis of flavin adenine dinucleotide (FAD), a coenzyme required for efficient cellular respiration. This coenzyme allows cells to obtain energy from nutrients, ensuring that they function properly.

  • Energy Production: Riboflavin’s vital role in energy production has been constantly supported by scientific studies. Riboflavin is involved in the electron transport chain within mitochondria, where it works as a cofactor for flavin mononucleotide (FMN) and FAD, according to research published in “Biochemistry” (2018). These coenzymes are essential for converting nutrients from food into adenosine triphosphate (ATP), the body’s principal energy currency. The study confirmed that riboflavin deficiency might result in decreased energy generation, emphasising the necessity of riboflavin in supporting everyday activities and metabolic processes.
  • Skin Health: Scientific evidence supports riboflavin’s beneficial effect on skin health. Its importance in encouraging normal cell growth and healing in the skin was highlighted in a study published in the “Journal of Drugs in Dermatology” (2019). Furthermore, the antioxidant properties of riboflavin have been studied in research that show its capacity to protect skin cells from oxidative stress and free radical damage. This is especially important for preserving a youthful and healthy complexion.

Finally, vitamin B2, often known as riboflavin, is a scientifically proven supplement with numerous health benefits. Its well-known contributions to cell health, energy production, and skin upkeep make it an essential component of general well-being and vigour.


When vitamin B2, commonly known as riboflavin, is consumed by food or supplements, it plays an important part in a variety of physiological processes within the human body. Riboflavin is predominantly absorbed in the small intestine after intake. Riboflavin is enzymatically converted in the liver into two active coenzyme forms, flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD). These coenzymes are required for a variety of metabolic reactions, particularly those involving energy production.

FMN and FAD function as cofactors for a variety of enzymes involved in the metabolism of carbohydrates, lipids, and proteins. They are essential components of the electron transport chain, a critical function within the mitochondria that produces energy. Riboflavin aids in the conversion of nutrients from food into adenosine triphosphate (ATP), the body’s principal energy currency. Furthermore, riboflavin helps to maintain healthy skin, eyes, and nerve function, emphasising its importance in general health.


Riboflavin supplementation at small levels of 1-2 milligrammes (mg) per day is commonly used to maintain adequate riboflavin status in the body. This dosage level adequately sustains and replaces the body’s riboflavin reserves. According to research, greater doses, such as 4mg, may hasten the accumulation of riboflavin reserves, while they are expected to produce equivalent long-term advantages. Notably, this recommended dosage range also applies when attempting to lower homocysteine concentrations, demonstrating its efficacy in addressing this specific health risk. It is critical to emphasise the need of consulting a healthcare practitioner before beginning any supplementation regimen to identify the most appropriate dosage while taking individual health requirements and considerations into account.

These guidelines are consistent with scientific data that highlight the effectiveness of modest riboflavin dosages in maintaining appropriate riboflavin levels. Riboflavin supplementation has been shown in studies to effectively treat deficits and contribute to overall health improvement at daily levels as low as 1-2mg. Furthermore, investigations on the effect of riboflavin on homocysteine levels have yielded positive results, confirming the benefits of this low dosage levels. However, it is critical to recognise that individual reactions may differ and that unique health situations may need personalised suggestions. As a result, consulting with a healthcare physician is still essential in selecting the most appropriate and effective riboflavin supplementation plan for individual needs.
