Overt deficiency is rare
High-dose biotin can seriously interfere with laboratory tests

What it does in the body
- Cofactor for several carboxylase enzymes
- Participates in fatty-acid synthesis
- Participates in glucose and amino-acid metabolism

Because evidence was insufficient to establish an RDA, an Adequate Intake is used. For adults it is 30 µg/day; lactation increases this to 35 µg/day.
What can deficiency look like?
- Hair thinning can occur in deficiency

FOOD FIRST
Food sources
A varied diet is the first place to look for nutrients. Availability and nutrient content can vary by food, preparation and country.
Eggs
Fish and meat
Nuts and seeds
Sweet potatoes
Some vegetables and dairy products
Food-source note: Biotin is present in many foods, which is one reason frank dietary deficiency is uncommon.
Absorption & practical context
Free biotin is absorbed in the small intestine. Food biotin must be released from protein-bound forms during digestion.
Important interactions
- High-dose biotin can produce falsely high or falsely low results in many immunoassays, including some thyroid and cardiac troponin tests
- People taking high-dose biotin should tell clinicians and laboratories before blood testing
Safety and context
No tolerable upper intake level has been established, but high supplemental doses can create clinically dangerous laboratory-test interference even when they do not cause classic toxicity.
