Thorne Biotin supplement for hair, skin, nails, and energy metabolism — Thorne

Thorne Biotin is a water-soluble B vitamin that can have a beneficial effect on a number of bodily structures and functions.

Biotin in a larger amount, as is present in Thorne's Biotin-8, supports glucose metabolism by stimulating glucose-induced insulin secretion in pancreatic beta cells and accelerating glucose metabolism in the liver. Biotin also increases muscle insulin sensitivity by increasing glucose uptake by muscle cells.

Thorne's Biotin 8 is a highly effective biotin supplement, an essential vitamin for healthy skin, hair, and nails. Biotin, also known as vitamin B7, is a fundamental nutrient for keratin production, which can help strengthen hair and nails, promoting healthy growth and a natural shine.

This supplement is ideal for those looking to improve skin appearance, strengthen brittle nails, or stimulate healthy hair growth. Biotin also plays a vital role in energy metabolism, helping to convert food into energy and promoting an overall sense of well-being.

Biotin deficiency can lead to problems such as hair loss, brittle nails, and dry skin. Biotin 8 offers the ideal dose of this vitamin to help restore and maintain hair and skin health.


✅ Hair strengthening: Can help promote healthy hair growth, reducing hair loss and improving shine.

✅ Stronger nails: Can strengthen fragile and brittle nails, helping to prevent cracks and chips.

✅ Skin health: Can help improve skin texture, preventing dryness and maintaining a healthy appearance.

✅ Energy metabolism support: Biotin can help convert food into energy, promoting more vitality.

✅ Nutritional balance: Biotin aids in fatty acid synthesis and protein metabolism.

How to use: 1 Capsule per day, or as directed by a healthcare professional

Therefore, the inclusion of Biotin B8 in your daily routines can result in stronger and shinier hair. Furthermore, many users report a reduction in hair loss, making this vitamin a valuable ally for those who want to maintain a healthy head of hair.

What is Thorne Biotin?

It is a high-dose biotin (vitamin B7) supplement (8 mg / 8,000 mcg per capsule), in a vegetable capsule, gluten-free, soy-free, lactose-free and suitable for vegans. Biotin contributes to the maintenance of normal hair, skin and mucous membranes, to normal energy metabolism and to the normal functioning of the nervous system.

Can people with fragile hair, hair loss, or brittle nails benefit?

Biotin contributes to the maintenance of normal hair. Those experiencing more fragile hair, hair loss, or brittle nails may wish to integrate biotin into their daily care routine. The 8 mg per capsule dose can be an option for those seeking more robust biotin support. Always consult a healthcare professional for an individualized assessment.

Does biotin interfere with laboratory tests?

Yes. Biotin supplementation can interfere with certain blood test results – including cardiac markers, thyroid markers, vitamin D, and pregnancy tests. It is mandatory to inform your doctor that you are taking biotin before any clinical analysis and to discontinue use as medically instructed before blood collection.
