Magnesium dosage

Magnesium testing allows us to measure the content of this essential trace element in food, nutraceuticals, plant-based products, and environmental sources. Crucial for numerous biological functions, magnesium plays a role 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 the regulation of the nervous system.

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

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

Objectives and measured parameters

Magnesium levels are measured to:

• to determine the total magnesium concentration in food, plant, biological or environmental samples,
• ensure that fortified products comply with nutritional claims (e.g., "source of magnesium" or "rich in magnesium"),
• to ensure the accuracy of nutritional labeling,
• to 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 drinks, supplements, animal feed, fertilizers or plant extracts.

Analytical methods used

Magnesium measurement relies on several techniques recognized for their reliability and accuracy:

• ICP-OES (inductively coupled plasma optical emission spectrometry) : a method commonly used for the simultaneous quantification of major and trace mineral elements. It allows for the measurement of magnesium with excellent reproducibility in solid or liquid matrices.
• ICP-MS (inductively coupled plasma mass spectrometry) : the reference technique for detecting magnesium in trace amounts or in samples with very low concentrations. It combines sensitivity and selectivity, while also allowing for multi-element analysis.
• AAS (atomic absorption spectroscopy) : classic method suitable for routine analysis of simple products, including aqueous solutions and extracts.

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

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

Industrial and scientific applications

Magnesium testing is applicable 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, forages, premixes and dietary formulations for production or companion animals.
• Agronomy and botany : assessment of the mineral status of plants and soils, control of fertilization and nutrient transfer.
• Water and environment : quantification of magnesium in mineral, surface or industrial waters, within the framework of quality and regulatory monitoring.

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