About this product

Riboflavin is the only active and is supplied at 100 mg in a simple daily serving. That high-potency design suits a deliberate B2 plan better than ordinary nutritional maintenance.

The label uses regular vitamin B2 rather than riboflavin 5'-phosphate. A plain capsule is practical, but it does not add a delivery feature for a water-soluble vitamin.

The bottle provides a practical extended supply. Value is acceptable, though several comparable products provide the same basic ingredient more economically.

Who is it for
  • Adults intentionally seeking a high-potency riboflavin supplement
  • People who prefer a simple one-active capsule
Best for
  • Focused vitamin B2 supplementation
  • A straightforward single-ingredient routine

Pros

  • Clearly disclosed 100 mg amount
  • Single-active formula
  • Convenient one-capsule serving
  • Practical bottle supply

Cons

  • Uses standard riboflavin rather than an active coenzyme form
  • Amount is far above routine nutritional needs
  • No special delivery feature is listed
  • Complete excipient details are not provided in the input

Warnings

  • High-dose riboflavin commonly turns urine bright yellow; the color change is expected and harmless.
  • A large riboflavin serving may cause nausea or loose stools in sensitive users.
  • Long-term high-dose use is best reserved for a specific purpose rather than added casually to other B-complex products.

Product analysis

79 out of 100
A simple high-potency riboflavin capsule with a clearly disclosed amount. The standard form is less distinctive than active B2, while value is fair.
