Vitamin

Biotin

Biotin functions as a cofactor for five human enzymes that help process carbohydrates, fats and amino acids. It is a water-soluble vitamin required in relatively small amounts.

It contributes to normal energy metabolism and maintenance of healthy hair, skin and mucous membranes.

In everyday life, Biotin supports normal hair and skin maintenance while helping your body turn everyday food into usable cellular energy.

High-dose biotin can interfere with certain laboratory tests.

Ingredient overview

What it is

Biotin functions as a cofactor for five human enzymes that help process carbohydrates, fats and amino acids. It is a water-soluble vitamin required in relatively small amounts.

  • Scientific identity: Biotin; molecule: Biotin, vitamin B7.
  • How it works: Absorbed in the small intestine: Uptake is efficient via a dedicated transporter, and dietary intake is generally adequate. Attached to carboxylase enzymes: It is covalently bound onto five human carboxylases rather than floating free.
  • Primary function: It contributes to normal energy metabolism and maintenance of healthy hair, skin and mucous membranes.
  • What it supports: Biotin supports normal hair and skin maintenance while helping your body turn everyday food into usable cellular energy.
  • Important consideration: High-dose biotin can interfere with certain laboratory tests.

Formulation rationale

Why we use it

CARPEDIEM selected Biotin for a clearly defined role within a thoughtfully balanced formulation.

  • Formulation purpose: It contributes to normal energy metabolism and maintenance of healthy hair, skin and mucous membranes.
  • Used in: CARPEDIEM Hair Skin Nails, CARPEDIEM MultiWomen and CARPEDIEM Women’s Beauty & Wellness Stack and other appropriate CARPEDIEM formulations.
  • Works alongside: Biotin complements L-Cysteine and Hyaluronic Acid to support comprehensive daily nutritional support.
  • Meaningful contribution: Biotin supports normal hair and skin maintenance while helping your body turn everyday food into usable cellular energy. Supports normal energy-yielding metabolism and everyday nutrient utilisation.
  • Quality and scientific context: High-dose biotin can interfere with certain laboratory tests. 2 ingredient-specific studies are included because the research reports a relevant benefit.

Ingredient intelligence

How it works

Best known for hair and nails. Its actual job sits inside five enzymes.

Step 01 / 04

Absorbed efficiently.

A dedicated transporter takes it up in the small intestine, and normal diets generally supply enough.

Treatment of brittle fingernails and onychoschizia with biotin: scanning electron microscopy

Journal of the American Academy of Dermatology

This clinical study used scanning electron microscopy to assess brittle nails before and after biotin supplementation and reported improvements in nail structure. It is frequently cited but is small and does not establish that biotin improves hair or nails in people without deficiency or brittle-nail symptoms.

Brittle nails: response to daily biotin supplementation

This clinical study reported improvement in a proportion of participants with brittle nails after biotin supplementation. The uncontrolled design limits certainty and does not establish benefit for healthy nails.
