Biotin, also known as vitamin B7, is often marketed as the go-to supplement for hair, skin, and nails. While it’s true that biotin helps strengthen keratin—the protein your hair and nails are made of—it works best if you’re actually deficient.

Signs of biotin deficiency include hair thinning, brittle nails, and skin irritation. If you’re not getting enough from eggs, nuts, or whole grains, a supplement could help restore healthy growth.

Most over-the-counter products contain 5000–10,000 mcg of biotin, which is higher than daily needs—but generally safe. However, extremely high doses may affect lab results for hormones or heart markers, so talk to a doctor if you’re getting tests done.

Consistency is key. Results typically show up after 2–3 months of daily use, and should be paired with a balanced diet and good haircare habits.

To explore safe and effective biotin options, visit platforms like workout supplements. Sometimes, the simplest solution for healthier hair is just a daily capsule away.
