KAL Vitamina B2 100 mg - Riboflavina con ActivTabs, 60 Tabletas

What is Vitamin B2 (Riboflavin)?

Vitamin B2, also known as riboflavin, is a water-soluble vitamin essential for energy metabolism. It is part of the coenzymes FAD and FMN, involved in the production of energy from food. Riboflavin is naturally found in foods such as dairy products, eggs, lean meats, and leafy green vegetables. However, an insufficient diet or certain conditions may necessitate extra intake through supplements.

Main Science-Backed Benefits

Riboflavin performs multiple functions in the body, all recognized by the European Food Safety Authority (EFSA). Among the most notable benefits are:

• Normal energy metabolism: Riboflavin contributes to normal energy metabolism, helping to convert carbohydrates, fats, and proteins into usable energy.
• Nervous system: Contributes to the normal functioning of the nervous system.
• Maintenance of mucous membranes: Helps maintain mucous membranes in normal conditions, which includes the membranes of the digestive and respiratory tracts.
• Red blood cell formation: Riboflavin contributes to the maintenance of red blood cells in normal conditions, supporting oxygen transport.
• Iron metabolism: Participates in normal iron metabolism, essential for preventing anemia.
• Antioxidant protection: Contributes to the protection of cells against oxidative damage, fighting oxidative stress.

Recommended Dosage and Available Forms

The recommended daily intake of riboflavin for adults is approximately 1.4-1.6 mg. However, in supplement form, higher doses are used, such as the 100 mg offered by this product. This high dose can be useful in cases of confirmed deficiency or under professional supervision. KAL's ActivTabs format uses rapid dissolution technology that allows for efficient absorption. Furthermore, this supplement is suitable for vegans, as it contains no animal-derived ingredients.

Who should take riboflavin?

Riboflavin can be beneficial for people with restrictive diets, such as vegans or celiacs, who may have a lower intake of this vitamin. It is also recommended for athletes seeking to optimize their energy metabolism, as well as for those who wish to support skin and mucous membrane health. Older adults or those with certain digestive conditions may experience reduced absorption and benefit from a supplement.

Possible Side Effects and Contraindications

Riboflavin is a water-soluble vitamin, so excess is eliminated in the urine, which can give it an intense yellow color—a harmless effect. Very high doses can cause mild gastrointestinal discomfort. No serious toxicities have been described, but it is important not to exceed the recommended daily dose indicated on the packaging. As with any supplement, consult a healthcare professional before starting to take it, especially if you are pregnant, breastfeeding, or taking medication.

Frequently Asked Questions

Why 100 mg if the recommended daily intake is much lower?

Supplemental doses are higher than basic nutritional needs to cover possible deficiencies or to achieve optimal tissue levels. Riboflavin is safe even in high doses, and excess is excreted. However, the 100 mg dose should be used under professional recommendation.

How to take ActivTabs?

ActivTabs are designed to dissolve quickly in the mouth or in a glass of water. It is recommended to take one tablet daily with a meal for better absorption.

Is it suitable for vegans?

Yes, this product is vegan and contains no animal-derived ingredients.

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 children.
