Magnesium aspartate is a magnesium salt of aspartic acid. [1] It is used as a mineral supplement, and as an ingredient in manufacturing of cosmetics and household products. [1]
As magnesium is an essential micronutrient, [2] the use of magnesium aspartate as a supplement is intended to increase magnesium levels in the body. [3] [4]
Absorption of magnesium from different preparations of magnesium supplements varies, with some studies indicating that magnesium in the aspartate (and several other) forms has more complete absorption than magnesium oxide and magnesium citrate forms. [3]
In its evaluation in 2005, a scientific panel of the European Food Safety Authority concluded that the bioavailability of magnesium L-aspartate was similar to that from other organic magnesium salts and the more soluble inorganic magnesium salts. [5] Overall, it was concluded that organic salts of magnesium have the greatest water solubility and demonstrate a greater oral absorption and bioavailability compared to less soluble magnesium preparations such as magnesium oxide, magnesium hydroxide, magnesium carbonate and magnesium sulfate. [6]
Magnesium aspartate is a compound formed by the combination of the divalent magnesium cation (Mg2+) and the dicarboxylic amino acid aspartate (C4H6NO4-). [1] The chemical formula for this compound is Mg(C4H6NO4)2. [7]
The structure of magnesium aspartate consists of a central magnesium ion that is chelated, or bound, by two aspartate anions. The aspartate moiety contains a carboxyl group (-COOH), an amino group (-NH2), and a second carboxyl group, forming a dicarboxylic amino acid structure. [1] [7]
This chelated structure is responsible for the enhanced water solubility of magnesium aspartate compared to other magnesium salts, such as magnesium oxide or magnesium citrate. [7]
Magnesium deficiency is unlikely to occur from low dietary intake because magnesium is abundant in the food supply and the kidneys restrict its excretion via the urine. [2] Long-term deficiency of magnesium may result from chronic alcoholism or some prescription drugs. [2] Signs of deficiency that may require magnesium supplementation include loss of appetite, nausea, vomiting, fatigue, and weakness. [2]

Magnesium supplements and other magnesium containing products, such as antacids, can bind with prescription medicines, reducing their effectiveness. [2]
Adverse effects from magnesium occurring naturally in food have not been described. [3] However, excessive magnesium supplementation causes diarrhea — a side effect used by prescription as a laxative. [2] [3] Individuals with kidney disease have higher risk for adverse effects with magnesium supplementation. [2] [3] Excessive magnesium supplementation may cause a fall in blood pressure. [2] [3]
Calcium is a chemical element; it has symbol Ca and atomic number 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. It is the fifth most abundant element in Earth's crust, and the third most abundant metal, after iron and aluminium. The most common calcium compound on Earth is calcium carbonate, found in limestone and the fossilised remnants of early sea life; gypsum, anhydrite, fluorite, and apatite are also sources of calcium. The name derives from Latin calx "lime", which was obtained from heating limestone.
Pantothenic acid (vitamin B5) is a B vitamin and an essential nutrient. All animals need pantothenic acid in order to synthesize coenzyme A (CoA), which is essential for cellular energy production and for the synthesis and degradation of proteins, carbohydrates, and fats.
A nutrient is a substance used by an organism to survive, grow and reproduce. The requirement for dietary nutrient intake applies to animals, plants, fungi and protists. Nutrients can be incorporated into cells for metabolic purposes or excreted by cells to create non-cellular structures such as hair, scales, feathers, or exoskeletons. Some nutrients can be metabolically converted into smaller molecules in the process of releasing energy such as for carbohydrates, lipids, proteins and fermentation products leading to end-products of water and carbon dioxide. All organisms require water. Essential nutrients for animals are the energy sources, some of the amino acids that are combined to create proteins, a subset of fatty acids, vitamins and certain minerals. Plants require more diverse minerals absorbed through roots, plus carbon dioxide and oxygen absorbed through leaves. Fungi live on dead or living organic matter and meet nutrient needs from their host.
In the context of nutrition, a mineral is a chemical element. Some "minerals" are essential for life, but most are not. Minerals are one of the four groups of essential nutrients; the others are vitamins, essential fatty acids, and essential amino acids. The five major minerals in the human body are calcium, phosphorus, potassium, sodium, and magnesium. The remaining minerals are called "trace elements". The generally accepted trace elements are iron, chlorine, cobalt, copper, zinc, manganese, molybdenum, iodine, selenium, and bromine; there is some evidence that there may be more.
Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite. This is in accordance with Justus von Liebig's law of the minimum. The total essential plant nutrients include seventeen different elements: carbon, oxygen and hydrogen which are absorbed from the air, whereas other nutrients including nitrogen are typically obtained from the soil.
Calcium citrate is the calcium salt of citric acid. It is commonly used as a food additive (E333), usually as a preservative, but sometimes for flavor. In this sense, it is similar to sodium citrate. Calcium citrate is also found in some dietary calcium supplements. Calcium makes up 24.1% of calcium citrate (anhydrous) and 21.1% of calcium citrate (tetrahydrate) by mass. The tetrahydrate occurs in nature as the mineral Earlandite.
ATC code A12Mineral supplements is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products. Subgroup A12 is part of the anatomical group A Alimentary tract and metabolism.
Chromium(III) picolinate is a chemical compound with the formula Cr(C5H4N )3, commonly abbreviated as CrPic3. It is a bright-red coordination compound derived from chromium(III) and picolinic acid.
Magnesium deficiency is an electrolyte disturbance in which there is a low level of magnesium in the body. Symptoms include tremor, poor coordination, muscle spasms, loss of appetite, personality changes, and nystagmus. Complications may include seizures or cardiac arrest such as from torsade de pointes. Those with low magnesium often have low potassium.
Calcium citrate malate is a water-soluble calcium supplement. It is the calcium salt of citric acid and malic acid with variable composition.
Magnesium citrates are metal-organic compounds formed from citrate and magnesium ions. They are salts. One form is the 1:1 magnesium preparation in salt form with citric acid in a 1:1 ratio. It contains 11.33% magnesium by weight. Magnesium citrate is used medicinally as a saline laxative and to empty the bowel before major surgery or a colonoscopy. It is available without a prescription, both as a generic and under various brand names. It is also used in the pill form as a magnesium dietary supplement. As a food additive, magnesium citrate is used to regulate acidity and is known as E number E345.
Chelates in animal feed is jargon for metalloorganic compounds added to animal feed. The compounds provide sources of various metals that improve the health or marketability of the animal. Typical metals salts are derived from cobalt, copper, iron, manganese, and zinc. The objective of supplementation with trace minerals is to avoid a variety of deficiency diseases. Trace minerals carry out key functions in relation to many metabolic processes, most notably as cofactors for enzymes and hormones, and are essential for optimum health, growth and productivity. For example, supplementary minerals help ensure good growth, bone development, feathering in birds, hoof, skin and hair quality in mammals, enzyme structure and functions, and appetite. Deficiency of trace minerals affect many metabolic processes and so may be manifested by different symptoms, such as poor growth and appetite, reproductive failures, impaired immune responses, and general ill-thrift. From the 1950s to the 1990s most trace mineral supplementation of animal diets was in the form of inorganic minerals, and these largely eradicated associated deficiency diseases in farm animals. The role in fertility and reproductive diseases of dairy cattle highlights that organic forms of Zn are retained better than inorganic sources and so may provide greater benefit in disease prevention, notably mastitis and lameness.
Antinutrients are natural or synthetic compounds that interfere with the absorption of nutrients. Nutrition studies focus on antinutrients commonly found in food sources and beverages. Antinutrients may take the form of drugs, chemicals that naturally occur in food sources, proteins, or overconsumption of nutrients themselves. Antinutrients may act by binding to vitamins and minerals, preventing their uptake, or inhibiting enzymes.
Zinc l-aspartate, often simply called zinc aspartate, is a chelated zinc supplement. Zinc aspartate is a salt of zinc with the amino acid aspartic acid.
Magnesium salts are available as a medication in a number of formulations. They are used to treat magnesium deficiency, low blood magnesium, eclampsia, and several other conditions. Magnesium is an essential nutrient.
Zinc L-carnosine, often simply called zinc carnosine, and also known as polaprezinc, is a mucosal protective chelate compound of zinc and L-carnosine invented by Hamari Chemicals, Ltd. It is a quadridentate 1:1 complex of a polymeric nature. Although it contains 23% zinc and 77% L-carnosine by mass, zinc carnosine is a molecule and not a mixture of zinc and L-carnosine.
Calcium supplements are salts of calcium used in a number of conditions. Supplementation is generally only required when there is not enough calcium in the diet. By mouth they are used to treat and prevent low blood calcium, osteoporosis, and rickets. By injection into a vein they are used for low blood calcium that is resulting in muscle spasms and for high blood potassium or magnesium toxicity.
Constance Virginia Kies was an American nutrition scientist and dietitian. Kies worked as a public school teacher for three years before going against the traditional gender norms of her time and completing an M.S. and Ph.D. from the University of Wisconsin–Madison. Over the duration of her 30-year career at the University of Nebraska–Lincoln, Kies researched nutritional biochemistry. She demonstrated relationships between minerals, proteins, and dietary fiber through pioneering human subject research. Her findings led to advancements in human knowledge of copper and protein metabolism. She was honored with the Borden Award and was a fellow of the American College of Nutrition. Kies was a feminist and a member of the National Organization for Women and the Women's Equity Action League. She died of uterine cancer three months after her diagnosis.
Zinc is an essential trace element for humans and other animals, for plants and for microorganisms. Zinc is required for the function of over 300 enzymes and 1000 transcription factors, and is stored and transferred in metallothioneins. It is the second most abundant trace metal in humans after iron and it is the only metal which appears in all enzyme classes.
Potassium aspartate is a potassium salt of L-aspartic acid.
