Glucosamine dosage

Glucosamine is an amino sugar naturally present in connective tissue, cartilage, and crustacean exoskeletons. It is widely used as an active ingredient in dietary supplements intended to maintain joint health and relieve osteoarthritis pain. Its laboratory measurement is essential to ensure product compliance, traceability, and quality, particularly in a context of strict regulations and high consumer expectations.

Analytical methods for the determination of glucosamine

The dosage of glucosamine is based on precise and sensitive chromatographic techniques:

• HPLC (High Performance Liquid Chromatography) : After a derivatization step, glucosamine is reliably separated and quantified in complex matrices.
• LC-MS (Liquid Chromatography coupled with Mass Spectrometry) : allows finer and more specific detection, suitable for complex formulations and low concentrations.

These approaches guarantee reproducible results that comply with industrial requirements. They complement other bioactive compound assays offered in our catalog, such as the assay of theanine , trigonelline or tyramine .

Industrial applications and sectors concerned

Glucosamine dosage is particularly important in several areas:

• Nutraceutical : standardization of joint supplements, often associated with chondroitin or MSM (methylsulfonylmethane).
• Human nutrition : enrichment of functional drinks and health products for the elderly or sports populations.
• Animal nutrition : formulation of supplements for pets or horses to support mobility and joint comfort.
• Phytotherapy and marine ingredients : quality control of extracts from cartilage, crustacean shells or algae.

This service is complementary to other analyses geared towards joint health and well-being, such as the dosage of aescins or fucoidans .

Matrices analyzed for glucosamine

Glucosamine can be measured in a variety of matrices: crustacean extracts (shrimp, crab), dietary supplements in capsule, tablet, or powder form, enriched liquid formulations, functional foods, and marine ingredients used in nutraceuticals. Each matrix type has its own analytical preparation to ensure accurate results.

Standardization and regulatory compliance issues

Glucosamine content must be rigorously controlled in order to: ensure compliance with nutritional and health claims, verify the actual presence of the claimed active ingredient, compare consistency between production batches, and meet European and international regulatory requirements for food supplements. This approach helps to secure formulations and increase transparency for consumers and distributors.
