生物素英语翻译

If you’ve searched for “biotin,” you’re likely looking for more than just a simple translation. Your curiosity probably extends to what it is, what it does for your body, and how you can use it to support your health goals. This comprehensive guide is designed to answer all those questions and more.

What is Biotin? – The Core Translation and Identity

The direct English translation of “生物素” is Biotin. It is also widely known as Vitamin B7 and was historically referred to as Vitamin H (“H” for “Haar und Haut,” the German words for hair and skin).

Biotin is a water-soluble vitamin, meaning your body does not store it, so you need a consistent supply from your diet or supplements.

What Does Biotin Do? Unpacking Its Roles in the Body

Biotin is a crucial cofactor for several enzymes involved in fundamental metabolic processes. Its primary functions include:

1. Energy Production: It helps convert carbohydrates, fats, and proteins from the food you eat into usable energy.
2. Hair, Skin, and Nail Health: Biotin is famously associated with supporting the growth and strength of keratin, the primary protein that makes up your hair, skin, and nails. A deficiency can lead to hair thinning or skin rashes, which is why it’s a star ingredient in many cosmetic supplements.
3. Nervous System Support: It plays a vital role in the synthesis of neurotransmitters, which are essential for proper brain function and nerve signaling.
4. Gene Regulation: Biotin is involved in gene expression, helping to regulate how your genes function.

Who Needs Biotin and How to Get It?

1. Dietary Sources:
A balanced diet can typically provide sufficient biotin for most people. 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
• Legumes: Soybeans, peas, lentils
• Certain vegetables: Sweet potatoes, spinach, broccoli
• Whole grains: Oats, barley

2. Supplementation:
Biotin supplements are popular for targeting specific health and beauty concerns. They might be beneficial for:

• Individuals with signs of deficiency: Such as thinning hair, brittle nails, or a scaly red rash.
• People with specific conditions: Pregnant women, individuals with long-term antibiotic use, or those with metabolic disorders affecting biotin absorption.
• Those seeking cosmetic benefits: People looking to improve the strength and appearance of their hair, skin, and nails.

Important Considerations for Supplementation:

• Dosage: Biotin is generally considered safe, with few side effects at recommended doses. Common supplemental doses range from 2,500 to 10,000 mcg.
• Crucial Safety Warning: High doses of biotin can severely interfere with many common blood tests, including those for heart health (troponin) and thyroid function (TSH). This can lead to misdiagnosis. Always inform your doctor about any biotin supplements you are taking before getting lab tests done.

Frequently Asked Questions (FAQ)

Q1: Can biotin alone cure hair loss?
A: Biotin can help improve hair health if the loss is due to a biotin deficiency. However, hair loss has many causes (genetics, hormones, stress). Biotin is most effective as part of a comprehensive approach to health.

Q2: How long does it take to see results from biotin supplements?
A: As it takes time for new hair and nails to grow, you may need to take supplements consistently for several months (typically 3-6) before noticing a visible difference.

Q3: What is the recommended daily intake?
A: The Adequate Intake (AI) for adults is 30 mcg. Higher doses in supplements are common and considered safe, but it’s best to consult a healthcare professional before starting.
