21st Century, Biotin

21st Century Biotin is a dietary supplement that provides biotin, also known as vitamin B7 or vitamin H, which is part of the B-complex vitamins. Biotin plays an important role in supporting metabolism, hair, skin, and nail health. 

• Biotin is a water-soluble B-vitamin that supports several metabolic functions, including the conversion of food into energy (carbohydrates, fats, and proteins).
• It also plays a crucial role in the health of your hair, skin, and nails. Biotin is often included in supplements marketed for beauty benefits due to its role in maintaining strong, healthy hair and nails.

Benefits of Biotin:

• Hair Health: Biotin is commonly used to help support hair growth and strength. It is often recommended for individuals experiencing hair thinning or hair loss, as it helps in the production of keratin, the protein that makes up hair strands.
• Skin Health: Biotin may help improve the appearance of your skin, preventing dryness, flakiness, or other skin issues. Some studies have also shown that biotin supplementation could help with conditions like acne or eczema.
• Nail Health: Biotin supports the strength and growth of nails. It is sometimes used as a supplement for brittle nails that break easily.
• Metabolic Support: Biotin is essential for the metabolism of macronutrients (carbohydrates, fats, and proteins), and plays a key role in energy production.
• Nervous System: As part of the B-vitamins, biotin supports the health of the nervous system, helping to maintain cognitive function and manage stress.

Dosage & Serving Size:

• The exact amount of biotin in the 21st Century Biotin product may vary depending on the formulation (typically 1,000 mcg or 5,000 mcg per tablet). The dosage typically falls within the range of 1,000 mcg to 5,000 mcg per tablet.
• The Recommended Daily Allowance (RDA) for biotin is not well-established, as biotin deficiencies are relatively rare. However, the average intake for adults is usually around 30 mcg per day. The doses in supplements are much higher, but biotin is water-soluble, meaning excess amounts are generally excreted in the urine.

Usage:

• Biotin supplements are typically taken once daily, with or without food.
• If you are unsure about the proper dosage or if you're using biotin for a specific health concern (e.g., hair loss), it's always a good idea to consult with a healthcare provider.

Side Effects & Precautions:

• Common Side Effects: Biotin is generally well tolerated. Side effects are rare, but some people may experience mild gastrointestinal upset, such as nausea or cramping.
• High Doses: Even at higher doses, biotin is considered safe because the body excretes any excess. However, if you are taking other supplements or medications, it’s important to check if they contain biotin to avoid excessive intake.
• Lab Test Interference: It's worth noting that high doses of biotin can interfere with certain laboratory tests (such as thyroid function tests) and may cause inaccurate results. If you’re planning to have lab tests, notify your doctor about biotin supplementation.

Additional Information:

• Biotin and Hair Growth: While there is some evidence that biotin can improve the health and strength of hair and nails, significant results for hair regrowth may only be seen in individuals with biotin deficiency or those with specific hair-related conditions.
• Sources of Biotin in Food: Biotin is naturally found in foods like egg yolks, liver, nuts, seeds, and certain vegetables (like sweet potatoes). However, it can be challenging to get large amounts through food alone, which is why supplementation is popular.
