What Does Riboflavin Do?
- 400 mg riboflavin matches the common high-dose level used in migraine studies.
- The formula includes riboflavin 5'-phosphate sodium, an active form, but its individual amount is not disclosed.
- Riboflavin absorption is saturable, so a large single 400 mg dose may be partly excreted.

Overview
•This provides 400 mg riboflavin per capsule, far above the daily requirement, but riboflavin is water-soluble and has no established tolerable upper intake level for healthy adults.
•Bright yellow urine is expected with high-dose riboflavin and is usually harmless; mild nausea, stomach upset, or diarrhea can occur in sensitive users.
•The formula is simple and free from stimulants, herbs, sweeteners, preservatives, and artificial colors, which keeps interaction and intolerance risk relatively low.
•People using probenecid, tricyclic antidepressants, phenothiazine medications, or undergoing chemotherapy should ask a clinician before using high-dose B2 regularly.
•The official product page lists pregnancy and breastfeeding suitability, but the 400 mg dose is much higher than prenatal requirements, so use during pregnancy or lactation should be clinician-guided.
•The label states it does not contain major allergens such as dairy, egg, fish, shellfish, tree nuts, peanuts, wheat, soy, sesame, gluten, or GMOs.
