Biotin is one of the most popular supplements in hair and nail care — and also one of the most commonly taken incorrectly. Most biotin capsules sit in the stomach until the digestive process breaks them down, losing a significant portion of the active ingredient before it reaches circulation. Esther Formula’s Biotin Strips deliver biotin directly through the oral mucosa — which is fundamentally different, and meaningfully better.
This review covers what biotin actually does in the body, why the strip format gives it a delivery advantage over standard capsules, what the Esther Formula Biotin Strips contain, and who benefits most from this supplement.
What Is Biotin and What Does It Actually Do?
Biotin (vitamin B7, also known as vitamin H — from the German “Harr und Haut,” meaning hair and skin) is a water-soluble vitamin that functions as a coenzyme in multiple metabolic pathways. Its roles include:
Hair Growth
Biotin is a coenzyme in keratin synthesis — the structural protein that makes up hair. It supports hair growth and strengthens hair tissue, particularly when biotin levels are depleted.
Nail Strength
Nails are also composed primarily of keratin. Biotin supplementation is associated with harder, less brittle nails and reduced nail breakage in individuals with biotin deficiency.
Skin Health
Biotin is a coenzyme in fatty acid synthesis — essential for maintaining the skin’s lipid barrier. Biotin deficiency is linked to skin rashes, dryness, and dermatitis.
Energy Metabolism
Biotin is involved in carbohydrate, fat, and protein metabolism — the three primary energy pathways. Adequate biotin supports efficient energy production at the cellular level.
Blood Sugar Regulation
Biotin enhances the activity of pyruvate carboxylase, involved in glycogenesis. Research suggests biotin supplementation may support healthier glucose metabolism.
Keratin Production
Beyond hair: keratin is a key structural protein throughout the body. Biotin’s role in keratin metabolism supports the entire structural integrity of hair, nails, and skin cells simultaneously.
Who Is Likely to Be Biotin Deficient?
Biotin deficiency is more common than many people realise, particularly in populations that include:
Why the Strip Format Matters for Biotin Specifically
Biotin is water-soluble — meaning it dissolves in water and doesn’t accumulate in the body. Any excess is excreted through urine. This means consistent daily intake is essential, and the amount absorbed with each dose determines the supplement’s effectiveness.
Standard biotin capsules pass through the gastrointestinal tract, where a variable portion is absorbed in the intestines. The oral mucosal route used by Esther Formula’s strips bypasses this process — biotin absorbs directly through the highly permeable membrane in the mouth, entering the bloodstream before it ever reaches the digestive system. This translates to more consistent, efficient delivery with each daily strip.
Important note (safe overdose): Because biotin is water-soluble, taking it in doses above the recommended daily intake doesn’t accumulate or cause toxicity. Any excess is excreted. This is one reason biotin supplements commonly contain many multiples of the daily recommended amount — ensuring adequate absorption even when some is lost to digestion. The ODS format addresses this differently: higher efficiency absorption means less waste.
