Jamieson Vitamina B2 (Riboflavina) 100 mg, 100 comprimidos

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 complex and acts as a precursor to key coenzymes, such as flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD). These coenzymes are involved in numerous metabolic reactions, especially in the production of energy from food. Riboflavin is naturally found in foods such as milk, eggs, lean meats, and leafy green vegetables, but supplementation may be useful in cases of deficiency or when the body's needs increase.

Main Science-Backed Benefits

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

• Normal energy metabolism: Riboflavin helps convert carbohydrates, fats, and proteins into usable energy for cells. This is essential for maintaining an adequate level of vitality throughout the day.
• Tissue formation: It helps in the maintenance and repair of body tissues, including skin and mucous membranes.
• Nervous system function: It contributes to the normal functioning of the nervous system, supporting the transmission of nerve impulses.
• Red blood cell maintenance: It participates in the production and maintenance of red blood cells, which promotes oxygen transport.
• Iron metabolism: It aids in the absorption and utilization of iron, an essential mineral for blood.
• Protection against oxidative damage: It acts as an antioxidant, protecting cells from oxidative stress.

These benefits are recognized by the EFSA and are based on solid scientific evidence.

Recommended Dosage and Available Forms

The recommended daily dose of riboflavin for adults is approximately 1.4 to 1.6 mg. However, in supplements like Jamieson's, higher doses are offered, such as 100 mg per tablet. This amount largely exceeds basic needs but is used in specific contexts under professional supervision. Riboflavin commonly comes in the form of riboflavin (inactive form) or riboflavin 5'-phosphate (active form). Jamieson uses riboflavin in its conventional form, which is efficiently converted in the body. Each package contains 100 tablets, providing a supply for several months.

Who should take riboflavin?

Riboflavin supplementation can be especially useful for people with insufficient dietary intake, such as those following restrictive or strict vegetarian diets. It may also be recommended in cases of increased demand, such as during pregnancy, lactation, or in situations of intense physical stress. However, it is always advisable to consult a healthcare professional before starting any supplementation.

Possible Side Effects and Contraindications

Riboflavin is generally safe and well-tolerated. Being water-soluble, excess is eliminated in the urine, which can give it an intense yellow color, a harmless effect. Very high doses could cause mild digestive discomfort. It is contraindicated in people with hypersensitivity to any of its components. No serious drug interactions have been described, but it is advisable to inform your doctor about any supplements you are taking.
