Vitamina B-2 (Riboflavina) 100 mg, 100 Cápsulas (Paquete de 3)

What is Vitamin B2 (Riboflavin)?

Vitamin B2, also known as riboflavin, is a water-soluble vitamin essential for energy metabolism and cellular function. It is part of the B vitamin complex and acts as a precursor to key coenzymes such as flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), which are involved in numerous oxidation-reduction reactions in the body.

This NOW Foods supplement provides 100 mg of riboflavin per capsule, a dose much higher than recommended intakes (1.4-1.6 mg/day in adults), designed to meet specific needs. It comes in a pack of 3 bottles with 100 capsules each, with no added sugars.

Key Science-Backed Benefits

According to the European Food Safety Authority (EFSA), riboflavin contributes to:

• Normal energy-yielding metabolism.
• Normal functioning of the nervous system.
• The maintenance of normal mucous membranes.
• The maintenance of normal red blood cells.
• Normal iron metabolism.
• The protection of cells from oxidative stress.

These benefits are backed by decades of scientific research. Riboflavin is especially relevant for people with restrictive diets, athletes, or those looking to maintain high energy levels.

Recommended Dosage and Available Forms

The usual dose in food supplements ranges from 10 to 100 mg per day. Each capsule of this product contains 100 mg of riboflavin in its inactive form (riboflavin), which is converted in the body into the active forms FMN and FAD.

It is recommended to take one capsule daily with a meal, unless otherwise directed by your healthcare professional. Do not exceed the recommended daily dose. Riboflavin is water-soluble, so excess is mainly eliminated through urine, which may give it a harmless yellowish color.

Who Should Take Riboflavin?

This supplement may be suitable for:

• People with diets low in dairy, eggs, or organ meats (natural sources of riboflavin).
• Athletes looking to support energy metabolism.
• Individuals with increased oxidative stress.
• Those following vegetarian or vegan diets.

However, food supplements should not replace a balanced and varied diet.

Possible Side Effects and Contraindications

Riboflavin is considered safe at usual doses. At high doses, it can cause yellow or orange discoloration of the urine, which is harmless. Mild gastrointestinal upset may occasionally occur.

No significant drug interactions have been established, but consult a professional if you are taking other medications. Keep out of reach of children.

Frequently Asked Questions

Does riboflavin help with migraines? Some studies suggest that high doses of riboflavin (400 mg) may reduce the frequency of migraines, but EFSA has not approved this claim. Consult your doctor for available options.

What is the difference between riboflavin and riboflavin 5'-phosphate? Riboflavin 5'-phosphate is the phosphorylated and more bioavailable form, but conventional riboflavin is also efficiently converted in the body.

Can I take this vitamin along with other B vitamins? Yes, it is compatible. In fact, many people take it as part of a B complex. There are no known problems.

Food supplements should not be used as a substitute for a balanced and varied diet. Do not exceed the recommended daily dose.
