Benefits of Riboflavin

Riboflavin, or vitamin B-2, is essential for turning the food you eat into cellular energy. It supports normal energy-yielding metabolism, helps maintain healthy red blood cells, and provides antioxidant protection against oxidative stress. Many Canadians take this vitamin to support sustained energy levels, immune function, and the health of their skin, vision, and nervous system.

Source Naturals Vitamin B-2 delivers 100 mg of riboflavin per tablet—a potent dose to fill dietary gaps. As a water-soluble vitamin, any excess is harmlessly flushed out, which may cause a bright yellow colour in urine—a normal, harmless effect.

What Is Riboflavin (Vitamin B-2)?

Riboflavin is a water-soluble B vitamin that plays a key role in energy metabolism. It is a building block for two crucial coenzymes: flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD). These coenzymes help convert carbohydrates, fats, and proteins into usable energy at the cellular level. Riboflavin also assists other B vitamins like B-6 and niacin in their functions and contributes to normal red blood cell formation.

Because the body does not store riboflavin, regular intake from diet or supplements is necessary. While dairy, eggs, lean meats, and leafy greens contain it, many people choose a supplement like Source Naturals Vitamin B-2 to ensure consistent daily intake.

Who Should Consider a Riboflavin Supplement?

Individuals who may not get enough riboflavin from food—such as those on vegan or vegetarian diets—can benefit from supplementation. Athletes and active people often take it to support energy metabolism during exercise. Others may use riboflavin under a healthcare professional’s guidance for specific nutritional needs. Always assess your personal situation and consult a healthcare provider before starting a new supplement.

Recommended Dosage and Safety

The suggested use is one tablet daily, preferably with a meal. Riboflavin is generally well-tolerated; No tolerable upper limit has been established due to low toxicity, and studies have used up to 400 mg per day without adverse effects. Common side effects at high doses include bright yellow urine (harmless) and occasional mild digestive upset.

Keep out of reach of children and do not exceed the recommended dose unless directed by a healthcare professional. Pregnant or nursing women, those with medical conditions, or those taking medications should consult their healthcare provider before use.
