What is Biotin?
Biotin is a water-soluble B vitamin that helps your body convert food into energy. It’s sometimes called the “beauty vitamin” because of its powerful effects on hair and nails.
Your body doesn’t store biotin, which means you need to replenish it through diet or supplements. While foods like eggs, salmon, and nuts provide biotin, many people turn to supplements for an extra boost—especially when dealing with hair thinning or breakage.
Why Biotin is Essential for Healthy Hair
Biotin helps produce keratin, a structural protein that makes up hair strands. Without enough biotin, hair can become brittle, thin, or grow slower than usual. That’s why biotin supplements for hair growth are so popular—they target the root cause of weak follicles.
Common Signs of Biotin Deficiency
While biotin deficiency is rare, some telltale signs include:
- Thinning hair or hair loss
- Brittle nails
- Dry, irritated skin
- Fatigue and mood changes
If you’re noticing these issues, it might be worth considering a biotin supplement to fill the gap.
How to Choose the Best Biotin Supplement
Factors to Consider Before Buying

Most supplements range from 1,000 mcg to 10,000 mcg of biotin per serving. Higher doses don’t always mean better results—sometimes, your body only needs a moderate amount.
Form: Capsules, Gummies, or Tablets
Capsules are easy to swallow, gummies are tasty, and tablets often pack higher potency. Your choice depends on personal preference.
Additional Ingredients for Hair Support
Many brands add extras like collagen, zinc, or herbal extracts for stronger results.
