Source Naturals Vitamina B-2 Riboflavina 100 mg - 250 Comprimidos

What is Vitamin B2 (Riboflavin)?

Vitamin B2, also known as riboflavin, is a water-soluble vitamin essential for the body. It belongs to the B-complex group and plays a crucial role in cellular energy production. Riboflavin acts as a precursor to two key coenzymes: flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD). These coenzymes participate in oxidation-reduction reactions necessary for metabolizing carbohydrates, fats, and proteins.

This Source Naturals supplement provides 100 mg of riboflavin per tablet, a dose significantly higher than the recommended daily intake, ideal for those seeking an additional supply. Riboflavin is absorbed in the small intestine and stored in small amounts in the liver, kidneys, and tissues.

Main benefits backed by science

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

• Normal energy metabolism: Helps convert food into usable energy for cells.
• Normal functioning of the nervous system: Participates in the synthesis of neurotransmitters and the maintenance of myelin.
• Maintenance of mucous membranes in normal conditions: Promotes the health of mucous membranes.
• Maintenance of red blood cells: Involved in erythropoiesis.
• Normal iron metabolism: Facilitates the absorption and utilization of iron.
• Protection of cells from oxidative damage: Acts as an antioxidant by neutralizing free radicals.

Additionally, riboflavin is necessary for the activation of other B vitamins, such as B6 and folic acid.

Recommended dosage and available forms

The recommended daily allowance (RDA) of riboflavin for adults is 1.4-1.6 mg per day. However, in supplementation, doses of 10 to 100 mg are common. This product provides 100 mg per tablet, an amount that far exceeds the RDA, but is used in specific contexts such as energy support or under professional supervision.

Riboflavin comes in two main forms: inactive riboflavin (the one in this product) and riboflavin 5'-phosphate (active form). The inactive form requires conversion in the body, while the active form is ready for use. Both are effective, although the active form may be more bioavailable for some people.

It is recommended to take 1 tablet daily with food to facilitate absorption. Do not exceed the stated daily dose.

Who should take riboflavin?

Riboflavin can be beneficial for:

• People with restrictive diets (vegans, vegetarians, food intolerances) who may not reach optimal amounts.
• Athletes looking to support energy metabolism and reduce fatigue.
• People exposed to oxidative stress or with increased needs for B vitamins.
• Those with conditions affecting nutrient absorption (Crohn's disease, celiac disease, etc.), under medical supervision.
• Individuals who want to maintain healthy skin, nails, and hair.

It is important to consult a healthcare professional before starting supplementation, especially at high doses.

Possible side effects and contraindications

Riboflavin is generally safe. Being water-soluble, excess is eliminated in the urine, which can cause an intense, harmless yellow color. No toxicity levels have been established, but very high doses (several grams) could cause mild gastrointestinal discomfort.

There are no absolute contraindications, but caution is recommended in people with kidney or liver failure. No significant drug interactions have been reported, but it is always advisable to inform your doctor about any supplements.

As with all food supplements, keep out of reach of young children. Its use during pregnancy or lactation is not recommended without professional guidance.
