Pure Encapsulations Biotin 8mg is a high-strength biotin (vitamin B7) supplement in vegetarian capsules, providing 8mg of biotin in each capsule across a 60-capsule pack.

Key Features

• High-strength dose: 8mg of biotin per capsule (16,000% NRV), a much higher amount than the microgram doses found in a typical multivitamin.
• Supports energy, nerves and mood: biotin contributes to normal energy-yielding metabolism, normal macronutrient metabolism, and normal functioning of the nervous system and psychological function.
• Maintains hair and skin: biotin contributes to the maintenance of normal hair and normal skin.
• Can affect blood test results: doses in this range can interfere with the accuracy of certain laboratory blood tests, so it's worth telling your doctor or the lab that you're taking a biotin supplement before any test.
• Vegan and free from major allergens: the capsule and all ingredients are suitable for vegans, and the product is free from gluten, crustaceans, eggs, fish, milk, molluscs, peanuts, soybeans and celery.

Why is the biotin dose in this product so much higher than in a typical multivitamin?

Biotin is water-soluble, and many people take higher-strength, standalone biotin supplements like this one specifically to support hair and skin, rather than relying on the smaller amount included in a general multivitamin.

Can taking biotin affect blood test results?

Yes. Biotin supplements at doses of around 5mg to 10mg a day, which includes this product, can interfere with some biotin-based laboratory tests, such as thyroid function and cardiac troponin tests, and may cause falsely high or low results. Tell your doctor and the laboratory that you're taking a biotin supplement before having blood taken, as they may advise you to stop taking it for a period beforehand.

Can I take this if I'm pregnant or breastfeeding?

Speak to a doctor, midwife or pharmacist before taking this or any food supplement if you're pregnant, breastfeeding, taking medication, or have a medical condition.

What does biotin do for hair and skin?

Biotin is officially recognised as contributing to the maintenance of normal hair and normal skin. This means it supports hair and skin that are already functioning normally, rather than treating an existing hair or skin condition.

Biotin is generally well tolerated, and no significant direct side effects are established at typical supplemental doses. The main safety consideration with high-strength biotin like this product is its potential to interfere with the accuracy of certain blood tests rather than a direct effect on the body, see Warnings for details.
