Despite being a protein, research shows that fibrous, structural keratin is largely indigestible to humans. This reality often leaves many wondering: does keratin have nutritional value if we can't break it down and absorb it like other proteins?

Approximately one-third of pregnant women experience marginal biotin deficiency. Many use supplements to improve hair, skin, and nail health, but choosing the best one can be challenging.

Research consistently highlights the complementary roles of different structural proteins in supporting tissue health. This principle suggests that combining supplements like collagen and keratin can provide enhanced benefits, targeting the body's hair, skin, and nails more comprehensively than relying on a single protein source alone.

An adequate daily intake of biotin for adults is approximately 30 micrograms (mcg), yet many supplements contain thousands of micrograms. To truly understand what is the correct way to take biotin, it is crucial to move beyond the high-dose hype and focus on consistency, safety, and individual needs.

Keratin, the fibrous structural protein that forms your hair, skin, and nails, is not found within any single vitamin. The idea that a vitamin contains keratin is a common misunderstanding because certain vitamins are essential catalysts in the metabolic processes that enable your body to produce this protein.

The Cleveland Clinic reports that keratin is a protective protein the body naturally produces to form hair, skin, and nails. Therefore, the most direct answer to 'What is the best source of keratin?' isn't a food itself, but rather the essential nutrients your body needs to synthesize this crucial protein.

Over one-third of pregnant women develop a marginal biotin deficiency despite normal dietary intake, indicating that biotin levels can fluctuate even in specific populations. This raises a common question: **what happens if you stop taking biotin**, especially after consistent supplementation, and how do your body, hair, and nails respond?

The Adequate Intake for biotin is only around 30 micrograms (mcg) for adults, yet many supplements on the market offer significantly higher amounts, prompting many to question: should I take 5000 or 10,000 biotin for the best outcome?
