21st Century Biotin 10,000 mcg — High-Strength Support for Energy, Hair, Skin & Nails

If you’re looking for a convenient way to support your body’s metabolism and maybe give your hair, skin, and nails a boost, 21st Century’s Biotin 10,000 mcg capsules offer a powerful daily dose of this essential B-vitamin.

What It Does & Why It Matters

• Supports energy production and metabolism: Biotin (also known as vitamin B7) is a vital coenzyme in the metabolism of fats, carbohydrates, and proteins, helping your body convert food into usable energy.
• Helps maintain healthy hair, skin & nails: Biotin plays a key role in the formation of keratin — the basic protein that makes up hair, skin, and nails. For people with low biotin status, supplementation may support stronger hair and nails and healthier skin.
• Supports overall cell and enzyme function: As a water-soluble B vitamin, biotin helps sustain general metabolic functions in the body — supporting organ health, nerve function, and the efficient breakdown of nutrients.

What You Get

• High-potency dosage: 10,000 mcg per capsule — a strong dose that’s popular among people looking to supplement beyond what normal diet provides.
• Daily supplement format — easy to take with a meal or water; convenient for those with busy schedules.
• Support for multiple wellness areas — useful not only for metabolic support but also for hair, skin, nails, and general vitality.

Important Considerations

• Biotin deficiency is rare for most people eating a balanced diet.
• Supplements may be most useful when dietary intake is low, or when specific conditions affect biotin absorption or needs.
• High-dose biotin can interfere with some lab tests — if you’re having blood tests (e.g. thyroid, hormones, or cardiac markers), let your doctor know you’re taking biotin.
• As with all supplements, consistent healthy eating, hydration, and overall healthy lifestyle increase the chance of seeing meaningful benefits.
