Description
"Vitamin B2" (riboflavin) is a water-soluble vitamin found in dairy, eggs, lean meats, and green vegetables. As part of cellular metabolism, it helps convert nutrients into energy while supporting red blood cell formation. Furthermore, this vitamin contributes to visual health by reducing eye fatigue and aiding overall function. Its presence is necessary for maintaining consistent energy levels and assisting in nutrient absorption. Since the body does not store riboflavin, regular dietary intake is essential for metabolic balance.

Deficiency Symptoms
A deficiency in Vitamin B2 can lead to weakness, fatigue, sore throat, cracks/sores on lips, inflammation of the tongue, and scaly skin or dermatitis.
Synergists & Antagonists
Vitamin B2 works synergistically with vitamins A, B1, B3, B5, B6, B9, PABA, B12, and minerals like chromium, copper, iron, potassium, magnesium, phosphorus, and zinc to support energy metabolism, cellular function, and metabolic health. However, it may be antagonized by vitamin B1, calcium, copper, iron, manganese, sodium, and potassium, as high levels of these nutrients can interfere with its absorption.
