🧪 Formulation Notes

Riboflavin

Supports energy production

Vitamin B-2, also known as riboflavin, is a component of two enzymes: flavin mononucleotide (FMN), and flavin adenine dinucleotide (FAD). These enzymes are important in energy production, and are essential for normal fatty acid and amino acid synthesis. Because of their vital roles, cellular growth cannot take place in the absence of vitamin B-2 riboflavin.

Suitable for vegetarians and hypoallergenic, contains no yeast, dairy, egg, gluten, corn, soy or wheat. Contains no sugar, starch, salt, preservatives, or artificial color, flavor or fragrance.
