Health Benefits
Strengthens keratin structure, reduces breakage, and supports follicular resilience for fuller, healthier hair.
Enhances dermal hydration, elasticity, and barrier repair by supporting fatty acid metabolism, promoting skin health.
Reduces brittleness and supports firm, fast-growing nails through enhanced keratin synthesis.
Acts as a coenzyme in the conversion of fats, proteins, and carbohydrates into cellular energy via the Krebs cycle.
Improves insulin sensitivity and supports glucose metabolism, contributing to stable energy and metabolic health.
Prevents symptoms of deficiency such as hair thinning, dermatitis, fatigue, and neurological disturbances.
Origin & History
Vitamin B7, also known as biotin, is a water-soluble B vitamin fundamental for cellular energy metabolism, keratin infrastructure, and enzyme function. Found in eggs, seeds, nuts, leafy greens, and liver, biotin is essential for maintaining radiant skin, resilient hair, strong nails, and balanced glucose metabolism. It functions as a coenzyme in carboxylase reactions, facilitating the synthesis of fatty acids and amino acid catabolism, while promoting cellular regeneration and hormonal stability.
“Biotin was first identified as a growth factor in yeast in the early 20th century and later recognized as an essential vitamin for humans. Its traditional presence in whole foods like eggs and liver has long contributed to healthy skin, hair, and metabolic function, though its specific biochemical role was elucidated more recently.”Traditional Medicine

Frequently Asked Questions
What is Vitamin B7 (Biotin)?
Vitamin B7, commonly known as biotin, is a water-soluble B vitamin that acts as a coenzyme for carboxylase enzymes involved in fatty acid synthesis, amino acid catabolism, and gluconeogenesis. It is widely recognized for supporting keratin structure in hair, skin, and nails, and is found in foods like eggs, nuts, seeds, and liver.
Does biotin really help with hair growth?
Biotin supplementation has strong evidence for improving hair and nail quality in individuals with biotin deficiency or brittle nail syndrome. However, evidence for hair growth benefits in people with adequate biotin levels is limited and largely anecdotal. Most clinical trials showing benefit involved deficient populations. A balanced diet typically provides sufficient biotin for most people.
Can biotin interfere with blood tests?
Yes, this is an important safety consideration. High-dose biotin supplements (commonly 5000-10000 mcg) can interfere with laboratory immunoassays that use streptavidin-biotin technology, potentially producing false results for cardiac troponin, thyroid function, hormone levels, and other critical tests. Discontinue biotin at least 72 hours before any blood work and inform your healthcare provider.
