Table 1 — Characteristics of riboflavin and riboflavin 5′-phosphate, sodium salt
Riboflavin and riboflavin 5′-phosphate, sodium salt as vitamin B2 is involved in the metabolism of proteins, fats and carbohydrates. The main biological role is participation in the redox reactions of the body.

- skin inflammation;
- inflammations of the mucous membranes of the mouth and eyes;
- significant loss of appetite and weakness;
- frequent headaches;

In addition, it should be noted that the negative impact of a dietary supplement is possible with its excess. So, the development of various kinds of allergies is possible, and dysfunction of the kidneys, as well as of the organs of vision, can also be provoked.
The daily consumption rate of E101 dye obtained with products artificially enriched with it should not exceed a threshold of 0.5 mg per 1 kg of body weight.
