生物素
对强韧头发、皮肤和能量代谢至关重要的B族维生素。
生物素，又称维生素B7，是美丽B族维生素——因维持正常的头发、皮肤和指甲而受到认可。存在于我们的Vitamin B Complex和Skin Hair & Nails配方中。
What is Biotin?
Biotin (vitamin B7) is a water-soluble B vitamin that acts as a cofactor for five carboxylase enzymes essential for macronutrient metabolism. These enzymes are critical for the synthesis of fatty acids, the breakdown of branched-chain amino acids, and the process of gluconeogenesis — the production of glucose from non-carbohydrate sources. Biotin is also involved in cell signalling and gene expression through its role in biotinylation of histones, the proteins that package DNA.
The name 'biotin' comes from the Greek word 'biotos', meaning 'life' or 'sustenance', reflecting its fundamental role in cellular energy metabolism. Biotin is perhaps best known for its recognised contribution to the maintenance of healthy hair and skin — it is one of the most popular nutrients in beauty-from-within supplements. It is naturally present in many foods including eggs, nuts, seeds, and certain vegetables.
EFSA-approved health benefits
The European Food Safety Authority (EFSA) has confirmed that biotin:
- contributes to normal energy-yielding metabolism
- contributes to the normal functioning of the nervous system
- contributes to normal macronutrient metabolism
- contributes to normal psychological function
- contributes to the maintenance of normal hair
- contributes to the maintenance of normal skin
- contributes to the maintenance of normal mucous membranes
Why we use Biotin in Nutri-Leaf formulas
Nutri-Leaf Skin Hair & Nails contains biotin alongside zinc, copper, and four plant extracts (bamboo shoots, millet, nettle, horsetail) in a comprehensive single-capsule formula for hair, skin, and nail support. Biotin is included at a level that complements the other nutrients in the formula, and the whole product is manufactured at our FSSC 22000 certified facility in 德国, Germany.
