Biotin, often marketed as a beauty vitamin, has garnered significant attention lately for its reputed benefits in promoting strong hair, nails, and glowing skin. Biotin is also known as Vitamin H and is part of the essential B-complex group of vitamins (source – NIH).
What Does Biotin Do?
As a water-soluble B vitamin, biotin plays a vital role in converting carbohydrates, fats, and proteins from the food you eat into the energy your cells need (research). By supporting carbohydrate metabolism and cellular respiration, biotin helps your body build new cells—key for hair, nail, and skin health (study). This improved cell production is what can make hair and nails grow stronger and faster, and skin appear healthier and more radiant (reference).
Why Are B-Complex Vitamins Important?
The B-complex group, beyond biotin, supports the health of your eyes, liver, digestive tract, blood sugar regulation, and nervous system (resource). Since these vitamins are water-soluble, your body doesn't store them, so regular intake through diet or supplements is important.
Where Can You Get Biotin?
Biotin is abundant in many dietary sources, including:
- Cooked eggs (especially yolks)
- Brewer's yeast
- Sardines
- Nuts (almonds, peanuts, pecans, walnuts) and nut butters
- Legumes (soybeans, black-eyed peas, beans)
- Whole grains
- Cauliflower
- Bananas
- Mushrooms
While the best way to obtain biotin is from whole foods, some people choose to supplement—often upon their healthcare provider’s advice. Research shows that supplementation can be beneficial for those with a deficiency or increased biotin needs (research). Biotin is widely available as part of multivitamins, B-vitamin complexes, and as standalone supplements. It is also plant-based and non-toxic, and excess biotin is typically eliminated from the body without causing harm (resource).
Safety First: Always consult your healthcare provider before starting any new vitamin regimen. While biotin is generally safe and overdose is rare due to its water solubility, professional guidance ensures you take the right dose for your needs.
Biotin is just one part of a balanced diet. Remember, overall nutrition from a variety of fruits, vegetables, and whole foods is key to maintaining your healthiest hair, nails, and skin.
