Vitamin B8 (biotin) dosage

Vitamin B8, better known as biotin , is a water-soluble vitamin essential to the body. It is involved in many metabolic functions, including the metabolism of carbohydrates, fatty acids, and amino acids. It also plays a key role in maintaining healthy skin, hair, and nails. Biotin dosage is therefore essential in cosmetic products, dietary supplements, and nutritional formulations intended to support vitality or beauty.

Analytical methods: HPLC, LC-MS/MS and microbiology

YesWeLab offers several validated techniques for the quantitative analysis of biotin, depending on the nature of your samples and the level of precision required:

• HPLC (high-performance liquid chromatography): A commonly used method for quantifying biotin in extracts, powders, and simple formulations.
• LC-MS/MS (liquid chromatography coupled with tandem mass spectrometry): offers excellent sensitivity, particularly useful for complex matrices or low contents.
• Microbiological method: sometimes required by certain pharmacopoeias or reference systems, particularly for raw materials or products intended for export.

Our partner laboratories carry out these analyses in compliance with ISO 17025 standards, using methods validated according to good analytical practices.

Why measure biotin?

Biotin dosage meets several strategic objectives:

• Ensure that fortified products comply with authorized nutritional claims (e.g., “source of biotin,” “contributes to the maintenance of normal skin and hair”).
• Validate dermo-cosmetic or hair formulas incorporating vitamin B8 as a beauty active ingredient.
• Control the stability of biotin in sensitive matrices (liquid formulations, beverages, plant extracts).
• Meet regulatory requirements for labeling, ingredient declaration or marketing.
• Evaluate the quality of raw materials and verify the effectiveness of enrichment processes.

Affected matrices

Biotin analysis is feasible on a wide range of products and ingredients, including:

• Food supplements: tablets, capsules, powders, syrups
• Functional foods: nutritional bars, fortified drinks, meal replacements
• Plant extracts, enriched yeasts, technical ingredients
• Cosmetics: hair care, serums, revitalizing creams, nail products
• Premix and animal nutrition products

Each matrix benefits from an adapted extraction and processing protocol, in order to guarantee the reliability of the results.

Sectors of application

Vitamin B8 dosage applies to many industrial fields:

• Nutraceuticals: development of supplements targeting beauty, energy or metabolism
• Cosmetics: formulation and control of hair products, anti-hair loss, revitalizers
• Food industry: control of fortified foods and validation of claims
• Animal nutrition: evaluation of vitamin content in feed intended for livestock or pets
• Research and development: optimization of formulations and evaluation of stability over time
