Windmill Vitamina B-2 (Riboflavina) 50 mg, 100 Comprimidos (Pack de 3)

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 acts as a precursor to key coenzymes such as flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), which are necessary for numerous metabolic reactions. Riboflavin is not stored in large quantities in the body, so it is necessary to obtain it regularly through diet or supplementation.

This Windmill supplement provides 50 mg of riboflavin per tablet, a dose much higher than the recommended daily intake, ideal for those seeking an extra boost. The formula is vegan, GMO-free and gluten-free, and is free of common allergens such as soy, dairy, and artificial preservatives. Each pack includes three bottles of 100 tablets, providing a supply for several months.

Main benefits backed by science

Riboflavin contributes to several fundamental physiological processes, according to claims approved by the European Food Safety Authority (EFSA):

• Normal energy metabolism: Riboflavin helps convert food into usable energy for cells, which can help reduce fatigue and tiredness.
• Normal functioning of the nervous system: It participates in the synthesis of neurotransmitters and in the protection of myelin sheaths, supporting neurological health.
• Maintenance of mucous membranes under normal conditions: It promotes the integrity of mucous membranes, such as those of the digestive and respiratory tracts.
• Maintenance of red blood cells: It collaborates in the formation and maturation of erythrocytes, essential for oxygen transport.
• Normal iron metabolism: Riboflavin optimizes the absorption and utilization of dietary iron.
• Protection of cells from oxidative damage: It acts as an antioxidant, neutralizing free radicals that can damage cells.

These benefits have been backed by the EFSA, so they can be included in product labeling and communication. It is important to note that riboflavin does not prevent or cure diseases, but rather contributes to the maintenance of health within a balanced diet.

Recommended dosage and available forms

The recommended daily intake of riboflavin for adults is approximately 1.4-1.6 mg. Each tablet of this supplement provides 50 mg, a much higher dose that is commonly used in supplementation aimed at covering deficiencies or specific needs. It is recommended to take one tablet daily, preferably with a meal to facilitate absorption.

There are two main forms of vitamin B2 on the market: riboflavin (inactive form) and riboflavin 5'-phosphate (active form). This product contains riboflavin in its inactive form, which the body converts into the active coenzymes FMN and FAD. For most people, this conversion is efficient, so conventional riboflavin is adequate. Each bottle contains 100 tablets, and the 3-pack offers 300 tablets in total.

Who should take riboflavin?

Riboflavin supplementation can be beneficial for several groups:

• People with restrictive diets: Vegans, vegetarians, or those who eliminate dairy and eggs may have an insufficient intake of riboflavin.
• Athletes and active people: Increased energy expenditure increases the demand for B vitamins involved in metabolism.
• People over 50: Nutrient absorption can decrease with age, making a supplement useful.
• People with certain digestive conditions: Disorders such as Crohn's disease or celiac disease can affect riboflavin absorption.
• Pregnant or breastfeeding women: Riboflavin needs increase during these stages, although always under medical supervision.

If you think you may have a deficiency, consult a healthcare professional before starting supplementation.

Possible side effects and contraindications

Riboflavin is generally well tolerated, even in high doses. Being water-soluble, excess is eliminated in the urine, which may acquire an intense, harmless yellow color. No serious adverse effects have been described with high intakes. However, as with any supplement, it is recommended not to exceed the indicated daily dose. People with severe liver or kidney disease should consult their doctor before using this product. Its use in children is not recommended without professional guidance.

Frequently asked questions

What is the difference between riboflavin and riboflavin 5'-phosphate? Riboflavin is the inactive form, which the body converts into the active coenzymes FMN and FAD. Riboflavin 5'-phosphate (also called FMN) is a more bioavailable form that does not require conversion. For most people, conventional riboflavin is sufficient, but those with absorption or conversion problems may benefit from the active form.

Can I take this supplement along with other B complex supplements? Yes, riboflavin acts in synergy with other B vitamins. In fact, a balanced B complex is often recommended. However, it is always advisable not to double doses without supervision.

How long does it take to notice the benefits? Effects on energy and general well-being can be noticed after several weeks of regular use, although each person is different. Riboflavin acts at a cellular level, and its benefits accumulate over time.

Is it safe to take 50 mg daily? Yes, it is considered a safe dose. The EFSA has not established an upper tolerable intake limit for riboflavin, and doses of up to 100 mg/day have been used in studies without adverse effects. However, it is advisable to follow the dose indicated on the package.

Food supplements should not be used as a substitute for a balanced and varied diet. Do not exceed the recommended daily dose. Keep out of reach of young children.
