Today we discuss our 2nd water-soluble B-vitamin, B2. We will briefly introduce Vitamin B2, lists Vitamin B2 food sources (mainly ingredients for smoothies), and highlight some additional interesting and important key notes.

Vitamin B2 Introduction

Vitamin B2 is also known as Riboflavin. Riboflavin has a break-down of 2 key component coenzymes named Flavin Mononucleotide (FMN) and Flavin Adenine Dinucleotide (FAD). FAD is needed to convert the amino acid tryptophan into niacin. FAD is also needed to convert Vitamin A Retinol into retinoic acid. Vitamin B2 is primarily absorbed in the small intestines. It plays a vital role in producing energy, fat metabolism, and cellular development & growth. People commonly supplement riboflavin to maintain healthy hair, nails, skin, and for its anti-aging properties.

Vitamin B2 Food Sources
