Riboflavin (Vitamin B2): Supply Situation

In the National Nutrition Survey II (NVS II, 2008), the dietary behavior of the population was investigated for Germany and it was shown how this affects the average daily nutrient intake with macro- and micronutrients (vital substances).

The intake recommendations (D-A-CH reference values) of the German Nutrition Society (DGE) are used as the basis for assessing nutrient supply. A comparison of the nutrient intake determined in the NVS II with the recommendations of the DGE shows for which micronutrients (vital substances) there is a frequent undersupply in Germany.

Regarding the supply situation, it can be stated:

  • Overall, 20% of men and 26% of women do not reach the recommended daily intake of vitamin B2.
  • The proportion is highest among women aged 65 and older, at 32%.
  • The worst supplied men lack 0.5 mg of vitamin B2. This corresponds to a daily shortfall of 33% of the recommended intake.
  • The worst supplied women lack 0.4 mg of vitamin B2. This also corresponds to a daily shortfall of 33% of the recommended intake.
  • Pregnant women (from the 4th month of pregnancy) have a daily excess requirement of 0.3 mg vitamin B2 compared to non-pregnant women. Correspondingly, the most poorly supplied pregnant women have a shortfall of 0.7 mg of vitamin B2 per day.
  • Breastfeeding women have an excess daily requirement of 0.4 mg of vitamin B2 over non-breastfeeding women. Correspondingly, the most poorly supplied breastfeeding women have a shortfall of 0.8 mg of vitamin B2 per day.

Since the intake recommendations of the DGE are based on the needs of healthy and normal-weight people, an individual additional requirement (eg due todiet, stimulant consumption, long-term medication, etc.) may be above the intake recommendations of the DGE.
