Riboflavin powder, RF, also known as vitamin B2, is a water-soluble B vitamin.
It is also an essential trace nutrient for the human body and must be obtained through exogenous food or nutritional supplements. Our company's riboflavin meets USP and BP standards.
The average daily requirement of riboflavin for healthy adults is 0.3~1.8 mg.
The synthesis methods of riboflavin include full chemical synthesis, chemical semi-synthesis and microbial fermentation, and microbial fermentation is currently the best production method for riboflavin.
Riboflavin has a wide range of physiological functions and is listed by the WHO as one of the indicators for assessing human growth, development and nutritional status.
