Magnesium dosage

Magnesium testing measures the content of this essential trace element in food, nutraceutical, plant, or environmental products. Essential for many biological functions, magnesium is involved in muscle contraction, nerve transmission, protein synthesis, and cellular energy regulation.

This analysis is performed using high-precision instrumental techniques such as ICP -OES , ICP -MS or atomic absorption spectroscopy (AAS) , depending on the type of matrix and the required sensitivity.

Magnesium: A key mineral for nutrition and metabolism

Magnesium (chemical symbol Mg) is the fourth most abundant cation in the human body after calcium, sodium, and potassium. It participates in more than 300 enzymatic reactions involved in energy metabolism, nucleic acid synthesis, and nervous system regulation.

Natural sources of magnesium are varied: mineral waters, dried fruits, legumes, green vegetables, whole grains, or algae. However, deficiencies can occur due to insufficient intake, digestive losses, or chronic oxidative stress, hence the importance of controlling the magnesium content in products intended for human or animal consumption.

The dosage of this element is also essential in the formulation of enriched food supplements or foods with specific nutritional purposes.

Objectives and measured parameters

The magnesium dosage aims to:

• determine the total concentration of magnesium in food, plant, biological or environmental samples,
• ensure compliance of enriched products with nutritional claims (for example “source of magnesium” or “rich in magnesium”),
• ensure the accuracy of nutritional labeling,
• control the quality and purity of mineral raw materials,
• verify the bioavailability of magnesium in nutraceutical or animal formulations.

The matrices analyzed may include: foodstuffs, mineral powders, fortified beverages, supplements, fodder, fertilizers or plant extracts.

Analytical methods used

Magnesium dosage is based on several techniques recognized for their reliability and precision:

• ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry) : A commonly used method for the simultaneous quantification of major and trace mineral elements. It allows magnesium to be measured with excellent reproducibility in solid or liquid matrices.
• ICP-MS (inductively coupled plasma mass spectrometry) : the benchmark technique for detecting magnesium in trace amounts or in samples with very low levels. It combines sensitivity and selectivity, while allowing multi-elemental determination.
• AAS (atomic absorption spectroscopy) : a classic method suitable for routine analyses of simple products, particularly aqueous solutions and extracts.

Depending on the sample type and expected content, the YesWeLab team selects the most appropriate method, guaranteeing accurate, reproducible results that comply with current standards.

YesWeLab also offers associated services such as calcium dosage , potassium dosage, sodium dosage and iron dosage , allowing a complete analysis of the mineral profile of products.

Industrial and scientific applications

Magnesium dosage applies to many sectors:

• Human nutrition and nutraceuticals : verification of magnesium content in food supplements, nutritional powders, functional drinks or fortified foods.
• Animal nutrition : control of mineral content in livestock feed, fodder, premixes and dietetic formulations for production or companion animals.
• Agronomy and botany : assessment of the mineral status of plants and soils, control of fertilization and transfer of nutrient elements.
• Water and environment : quantification of magnesium in mineral, surface or industrial water, as part of quality and regulatory monitoring.

Magnesium analysis can be combined with complementary services such as the dosage of phosphorus , copper or zinc , for a global evaluation of the elemental composition and nutritional potential of the matrices studied.
