What is Riboflavin?

Riboflavin (vitamin B2) is a water-soluble B vitamin that serves as a precursor for the coenzymes flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD). These flavocoenzymes are essential for numerous oxidation-reduction reactions in the body, playing a central role in the electron transport chain — the pathway responsible for the vast majority of cellular energy production. Riboflavin is also required for the metabolism of other B vitamins, including vitamin B6 and folate.

Riboflavin's active form, riboflavin-5'-phosphate (also called flavin mononucleotide), is the form that the body can use directly without enzymatic conversion. This is the form Nutri-Leaf uses in its Vitamin B Complex. Riboflavin contributes to the maintenance of normal vision, skin, and mucous membranes, and plays a role in iron metabolism. It also supports the body's antioxidant defences as a component of the glutathione reductase system.

EFSA-approved health benefits

The European Food Safety Authority (EFSA) has confirmed that riboflavin:

• contributes to normal energy-yielding metabolism
• contributes to the normal functioning of the nervous system
• contributes to the maintenance of normal skin
• contributes to the maintenance of normal mucous membranes
• contributes to the maintenance of normal vision
• contributes to the normal metabolism of iron
• contributes to the protection of cells from oxidative stress
• contributes to the reduction of tiredness and fatigue

Why we use Riboflavin in Nutri-Leaf formulas

Nutri-Leaf Vitamin B Complex uses riboflavin-5'-phosphate (the active coenzyme form of vitamin B2) rather than the more common riboflavin hydrochloride. The active form is immediately available to the body without requiring enzymatic conversion, making it particularly suitable for individuals with variations in riboflavin metabolism. Each capsule provides 1.4mg (100% NRV) as part of our comprehensive B vitamin complex.

Products containing Riboflavin

The Nutri-Leaf product featuring riboflavin is Vitamin B Complex, which delivers all eight B vitamins at 100% NRV per capsule in their active forms for energy metabolism, nervous system health, and the reduction of tiredness and fatigue.
