Vitamin B2 (Riboflavin) 50 mg – 200 Tablets (2 Packs of 100)

What is Vitamin B2 (Riboflavin)?

Vitamin B2, also known as riboflavin, is a water-soluble vitamin essential for the proper functioning of the body. It is part of the B vitamin complex and plays a key role in energy production at the cellular level. Riboflavin acts as a precursor to two fundamental coenzymes: flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), which are involved in numerous metabolic reactions, especially in the Krebs cycle and the electron transport chain.

Being water-soluble, excess riboflavin is eliminated through urine, so a daily intake through diet or supplements is necessary. This product offers 50 mg of riboflavin per tablet, a dose much higher than the recommended daily intake (RDI), ideal for those who need an extra supply.

Main scientifically-backed benefits

According to the European Food Safety Authority (EFSA), riboflavin contributes to several important physiological functions:

• Normal energy metabolism: Riboflavin helps convert food into usable energy for cells, which is fundamental for maintaining daily vitality.
• Normal functioning of the nervous system: It participates in the synthesis of neurotransmitters and in the protection of neurons against oxidative stress.
• Maintenance of mucous membranes under normal conditions: It contributes to the health of mucous membranes, such as those of the digestive and respiratory tracts.
• Maintenance of red blood cells: It intervenes in the production and maturation of erythrocytes, helping to transport oxygen.
• Normal iron metabolism: It facilitates the absorption and utilization of iron, which can be beneficial in cases of iron deficiency anemia.
• Protection of cells from oxidative damage: It acts as an antioxidant, neutralizing free radicals and reducing oxidative stress.

These benefits are officially recognized and are the result of decades of scientific research. It is important to note that food supplements should not be used as a substitute for a balanced and varied diet.

Recommended dosage and available forms

The recommended daily dose of riboflavin for adults is 1.4 to 1.6 mg per day. However, in certain situations, a higher intake may be necessary, such as in cases of diagnosed deficiency, restrictive diets, high-intensity athletes, or people with certain health conditions. This supplement provides 50 mg per tablet, a dose that far exceeds the RDI, but is considered safe for most adults.

Riboflavin is commonly presented in two forms: riboflavin (inactive form) and riboflavin 5'-phosphate (active form). This product uses riboflavin in its basic form, which is efficiently converted in the body to its active coenzymes. The 50 mg dose allows for high nutrient availability.

It is recommended to take one tablet daily, preferably with a meal to facilitate absorption. Do not exceed the recommended daily dose.

Who should take riboflavin?

Riboflavin can be beneficial for different profiles of people:

• People with vegetarian or vegan diets: The main sources of riboflavin are dairy products, eggs, and meat. Those who avoid these foods may have insufficient intake.
• Athletes: Increased energy expenditure and oxidative stress from intense exercise can increase riboflavin needs.
• Older adults: Vitamin absorption may decrease with age, so a supplement can help maintain adequate levels.
• Pregnant and lactating women: Vitamin needs increase during pregnancy and lactation; always under medical supervision.
• People with certain health conditions: Such as malabsorption disorders, celiac disease, or chronic alcohol consumption.

Before starting any supplementation, it is advisable to consult a healthcare professional.

Possible side effects and contraindications

Riboflavin is generally safe and well tolerated, even at high doses. The most common side effect is yellowing of the urine, which is harmless and is due to the excretion of excess vitamin. At very high doses (hundreds of milligrams), mild gastrointestinal discomfort may occur, but the 50 mg dose is considered safe for most adults.

No significant drug interactions have been reported, although it is always important to inform your doctor about any supplements you are taking. Do not exceed the recommended daily dose. Keep out of reach of young children.

Frequently asked questions

What dose of riboflavin is recommended?

The recommended daily intake for adults is 1.4 to 1.6 mg. However, doses up to 50 mg per day are considered safe and can be used under supervision to meet specific needs. This product provides 50 mg per tablet, allowing for flexible dosing.

Does riboflavin help with migraines?

Some studies suggest that high doses of riboflavin (400 mg/day) may reduce the frequency of migraines, but this claim is not approved by the EFSA. We cannot state that this product treats or prevents diseases. Consult your doctor for personalized advice.

What is the difference between riboflavin and riboflavin 5'-phosphate?

Riboflavin is the basic (inactive) form, while riboflavin 5'-phosphate (also called flavin mononucleotide or FMN) is the active form. The body efficiently converts riboflavin to FMN and FAD, so both forms have similar bioavailability. This product contains riboflavin in its basic form.

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