生物素英文翻译

When you search for the English translation of “生物素,” you’re looking for more than just a word. You’re seeking a deeper understanding of what Biotin is, why it’s important, and how it can benefit you. This comprehensive guide is designed to answer all your potential questions about this essential nutrient.

What is Biotin?

Biotin, also known as Vitamin B7 or Vitamin H, is a water-soluble vitamin that is a crucial cofactor for several enzymes in the body. These enzymes are involved in fundamental metabolic processes, including:

• Carbohydrate Metabolism: Converting carbs into usable energy.
• Fat Metabolism: Synthesizing and breaking down fatty acids.
• Protein Metabolism: Metabolizing amino acids, the building blocks of protein.

In simple terms, Biotin helps your body convert the food you eat into the energy it needs to function.

Key Benefits and Why It’s So Popular

The popularity of Biotin stems from its well-known and highly sought-after benefits, particularly for hair, skin, and nails.

1. Promotes Healthy Hair Growth: Biotin is most famous for its role in supporting strong, healthy hair. A deficiency in Biotin has been linked to hair loss. Therefore, adequate Biotin levels are essential for maintaining hair follicle health and promoting growth.

2. Strengthens Nails: Brittle, splitting nails can be a sign of nutritional deficiencies. Studies have shown that Biotin supplementation can significantly increase nail thickness and reduce splitting in people with brittle nails.

3. Supports Radiant Skin: Biotin plays a role in fat metabolism, which is important for maintaining healthy skin. A deficiency can lead to skin issues like red, scaly rashes. Proper Biotin levels help support the skin’s foundation, keeping it looking smooth and healthy.

4. Essential for Metabolic Health: Beyond beauty, Biotin is fundamental for your metabolism. It supports the nervous system and helps your body use glucose effectively, which is important for overall energy levels.

Natural Food Sources of Biotin

You can maintain healthy Biotin levels through a balanced diet. Excellent natural sources include:

• Organ meats: Liver and kidney
• Egg yolks (Note: Raw egg whites contain a protein that can block Biotin absorption)
• Nuts and seeds: Almonds, walnuts, peanuts, and sunflower seeds
• Legumes: Soybeans, peas, and lentils
• Whole grains: Oats and barley
• Certain vegetables: Sweet potatoes, spinach, and broccoli
• Bananas and mushrooms

Who Might Need Biotin Supplements?

While most people get enough Biotin from their diet, certain groups may benefit from supplementation:

• Individuals with a Biotin Deficiency: Diagnosed by a doctor, often presenting with hair loss, skin rashes, and brittle nails.
• Pregnant and Breastfeeding Women: Biotin requirements may increase during this time.
• People with Conditions Affecting Absorption: Such as Crohn’s disease or other digestive disorders.
• Those on Long-Term Antibiotic or Anticonvulsant Medication: These can interfere with Biotin levels.
• People Consuming Large Amounts of Raw Egg Whites: A habit sustained over many years can lead to deficiency.

Important Considerations and Safety

• Dosage: Biotin is generally considered safe, even at high doses. There is no established Tolerable Upper Intake Level (UL). Common supplemental doses range from 2,500 to 10,000 mcg.
• Crucial Safety Note: Laboratory Test Interference. This is the most critical warning about Biotin supplements. High doses of Biotin (typically > 5,000 mcg) can significantly interfere with many common blood tests (like thyroid tests—TSH, T3, T4—and troponin tests for heart attacks), leading to falsely high or low results. Always inform your doctor about any supplements you are taking, especially Biotin, before getting blood work. It is often recommended to stop taking Biotin for at least 3-5 days before testing.
• Side Effects: Biotin is very well-tolerated, and side effects are rare.
