The Active Ingredient Is: Vitamin B2 (Riboflavin)

Vitamin B2, also known as riboflavin, is a water-soluble B vitamin that acts as a key coenzyme in the metabolism of carbohydrates, fats and proteins. This form is riboflavin used as the active ingredient in a vegan capsule, supplied in a high-strength single-ingredient preparation.

This form supports basic cellular energy processes and is suitable for vegetarian and vegan lifestyles, aligning with clean-label principles observed in many Solgar products.

What Does Vitamin B2 Do?

Vitamin B2 contributes to normal energy production and supports the function of the nervous system, mucous membranes, skin and eyes. It also participates in antioxidant protection of cells, a role recognised in EFSA guidance and NHS-informed nutritional context.

Dr. Powers of the University found that riboflavin supplementation supports energy production and can contribute to reductions in tiredness in populations with suboptimal intake.
