Glucosamine dosage

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

Analytical methods for the determination of glucosamine

The measurement of glucosamine relies 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 for finer and more specific detection, suitable for complex formulations and low concentrations.

These approaches guarantee reproducible results that meet industrial requirements. They complement other bioactive compound assays offered in our catalog, such as the assays for theanine , trigonelline , and tyramine .

Industrial applications and sectors concerned

Glucosamine dosage is particularly important in several sectors:

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

This service is complementary to other analyses focused on joint health and well-being, such as the measurement 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, fortified liquid formulations, functional foods, and marine ingredients used in nutraceuticals. Each type of matrix requires a specific analytical preparation to ensure accurate results.

Challenges of standardization and regulatory compliance

The glucosamine content must be rigorously controlled to: guarantee 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 ensure the safety of formulations and enhance transparency for consumers and distributors.
