Overview
Riboflavin, commonly known as Vitamin B2, is a water-soluble vitamin that the body cannot store, meaning it must be consumed daily through diet or supplementation. It is a crucial component of two major coenzymes (FMN and FAD) that play major roles in energy production.
How It Works
Riboflavin is essential for breaking down proteins, fats, and carbohydrates to produce energy (ATP). It acts as an antioxidant, combating free radicals, and is heavily involved in cellular respiration.
Common Uses in Supplements
Riboflavin is widely used in formulations aimed at:
- Supporting daily energy levels
- Enhancing neurological and cognitive function
- Maintaining eye health and visual function
- Supporting healthy iron metabolism
What the Science Says
The role of Riboflavin in human biology is universally established. Deficiencies can lead to skin disorders, hyperemia, and other metabolic disruptions. Supplementing Riboflavin is generally considered very safe, as any excess is simply excreted by the body (often temporarily turning urine a bright yellow color).
Potential Side Effects
Because it is water-soluble, toxicity is extremely rare. However, very high doses may cause increased urination or diarrhea.
