What Is Biotin?
Biotin, also known as vitamin B7, is part of the B vitamin family. It plays an important role in energy metabolism, helping convert carbohydrates, fats, and proteins into energy. Biotin is an essential nutrient; your body does not produce it on its own. You must consume it through food or supplements.
Most adults need about 30 micrograms of biotin per day. A deficiency can lead to thinning hair, skin rashes, brittle nails, fatigue, and depression. While biotin supports healthy skin, nails, and hair, more biotin does not necessarily improve their condition. Research shows limited evidence that biotin supplements enhance hair or skin health.
5 Health Benefits of Biotin
-
May Strengthen Nails
High doses of biotin may help people with thin nails grow thicker and stronger nails. Research on this is limited, so more studies are needed.
-
May Promote Healthy Metabolism
Biotin is essential for converting food into energy. It helps process carbohydrates, proteins, and fats.
-
May Help Regulate Blood Sugar
Some studies suggest that biotin can lower fasting blood glucose for individuals with type 2 diabetes. Its effect on insulin requires further research.
-
May Support Brain Health
Adequate biotin intake may protect against depression, stress, and anxiety by supporting overall brain function.
- May Improve Heart Health
Regular biotin intake may help reduce total cholesterol and triglyceride levels, supporting heart health.
Food Sources of Biotin
Top food sources of biotin include:
- Beef Liver: 31 mcg per 3-ounce serving (103% DV).
- Eggs: 10 mcg per medium egg (33% DV), primarily in the yolk.
- Salmon: 5 mcg per 3-ounce serving (17% DV).
- Pork: Nearly 4 mcg per serving (13% DV).
- Sunflower Seeds: About 3 mcg per ¼ cup (9% DV).
The Bottom Line
Biotin supports metabolism, heart health, and brain function. While it is necessary for healthy hair, skin, and nails, excess biotin is unlikely to offer benefits. Eating a balanced diet usually provides sufficient biotin. Include biotin-rich foods like liver, eggs, salmon, and pork in your diet.
