NOW Biotina 5.000 mcg - 120 Cápsulas vegetales (Paquete de 2)

What is biotin and what is it for?

Biotin, also known as vitamin B7 or vitamin H, is a water-soluble B vitamin essential for numerous bodily functions. It acts as a cofactor in key enzymatic reactions related to macronutrient metabolism, helping to convert food into usable energy for the body.

This NOW Foods supplement provides 5,000 mcg of biotin per vegetable capsule (VCap), a generous dose ideal for those seeking an extra supply of this vitamin. The pack includes two bottles of 120 capsules each, providing a total of 240 doses.

Benefits supported by the EFSA

The European Food Safety Authority (EFSA) has approved the following health claims for biotin:

• Contributes to normal energy metabolism.
• Contributes to the normal functioning of the nervous system.
• Contributes to the maintenance of normal skin.
• Contributes to the maintenance of normal hair.
• Contributes to the maintenance of normal mucous membranes.

These properties make biotin a highly valued nutrient for personal care, especially regarding hair, skin, and nails.

Recommended dosage and method of consumption

The manufacturer's recommended daily dose is one vegetable capsule per day, preferably with a meal. Each capsule provides 5,000 mcg of biotin, well above the reference daily intake (50 μg/day in adults). However, high doses of biotin (up to 10,000 μg/day) are widely used in supplementation and have not been associated with adverse effects in studies.

NOW Foods capsules are plant-based (VCaps), suitable for vegetarians and vegans, and the product is gluten-free and soy-free.

Does biotin help hair and nails?

Although biotin is popularly known for its relationship with hair health, the EFSA only allows stating that it "contributes to the maintenance of normal hair" and the maintenance of skin and mucous membranes. This means that an adequate intake of biotin helps keep hair and nails in good condition, but therapeutic effects such as preventing hair loss or treating alterations cannot be attributed.

If you are looking for a supplement for hair care, biotin is an interesting complement within a balanced diet.

Safety and possible side effects

Biotin is a safe vitamin even in high doses, as excess is eliminated through urine as it is water-soluble. No significant adverse effects have been described at usual supplementation doses (up to 10,000 μg/day). However, it is important not to exceed the recommended dose by the manufacturer and consult with a healthcare professional if you are pregnant, breastfeeding, or taking medication.

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.

How to choose a good biotin supplement?

When selecting a biotin supplement, consider the presentation (capsules, gummies, tablets) and the dose per unit. NOW Foods uses D-biotin, the biologically active form, and its capsules are pharmaceutical grade. This pack of 2 bottles offers an excellent quantity-price ratio for prolonged consumption.

Always verify that the product is from a reputable brand and includes clear information about ingredients and allergens.
