What is Magnesium Aspartate?
Magnesium L- aspartate is a chelated magnesium salt of aspartic acid. Combining magnesium with aspartic acid
improves its bioavailability. Research shows this form of magnesium offers greater bioavailability than
magnesium oxide and magnesium citrate. Magnesium and aspartic acid both play important roles in human
metabolism, protein synthesis, and energy production.
Magnesium deficiencies are common, affecting 15-20% of the population in developed countries and up to 30% of
any given population. Many individuals fail to consume enough magnesium through dietary sources, and taking
a magnesium supplement can attenuate insufficiencies. The foods with the highest magnesium content include
leafy greens, beans, nuts, seeds, and animal tissue. Chronic deficiencies have a strong association with
type 2 diabetes, muscle twitching, hypertension, obesity, and malabsorptive conditions.
PureBulk’s magnesium l-aspartate consists of 12% magnesium by weight. Please note that Magnesium
L-Aspartate is insoluble in water. Please encapsulate this supplement, or add it
to fruit juice or smoothies to aid in taking.
What Does Magnesium Do in the Body?
Magnesium is an essential mineral and cofactor for more than 600 enzymatic reactions in the body. Every cell
in the body needs magnesium to function. It helps synthesize adenosine triphosphate (ATP) for energy and
metabolize carbohydrates. It’s also involved in synthesizing DNA and is essential for optimal protein
synthesis. The body uses magnesium for other biosynthetic processes, too, such as glycolysis and forming
cyclic adenosine monophosphate (cAMP).
Aspartic acid is an amino acid that exists in two forms: L-aspartic acid and D-aspartic acid. The L-isomer is the
proteinogenic form, meaning the body uses it to synthesize proteins. Like magnesium, aspartic acid helps
produce energy, as it is an intermediate in the citric acid cycle. Aspartate, the ionic form of aspartic
acid, is the precursor to several essential amino acids, including isoleucine, lysine, methionine, and threonine. Aspartate also plays a role in the urea
cycle to help remove highly toxic ammonia from the body.
Potential Magnesium Benefits
Magnesium for Exercise Performance
The body’s demand for magnesium increases during exercise. Clinical research shows that magnesium aspartate
is extremely effective at reducing fatigue, which may aid exercise performance. It also helps improve muscle
weakness and reduce muscle cramps. Another study found that magnesium supplements improved athletes’
physical performance, protected cyclists from muscle damage, and improved power output and muscle mass in
women. Individuals with insufficient magnesium may experience even greater improvements in exercise
Magnesium for Mood
Research has explored magnesium’s effect on mood for over a century. Magnesium converts into mood-regulating
neurotransmitters including tryptophan and serotonin. Magnesium deficiencies can lead to insufficient
serotonin and worsen mood disorders. Magnesium can also block N-methyl-D-aspartate (NMDA) ion channels. NMDA
receptors have a strong correlation to mood disorders, and inhibiting their excessive activation may improve
Magnesium for Sleep
Magnesium supplements may improve sleep quality. Individuals with insufficient magnesium often suffer from
sleep disturbances, as the body requires magnesium for quality sleep. Magnesium also plays a role in
synthesizing the sleep hormone melatonin. Magnesium binds to gamma-aminobutyric acid (GABA)
receptors to calm neuron excitement for better relaxation. Studies also show that magnesium helped
individuals fall asleep faster and stay asleep for longer.
Which Magnesium is Best for Constipation?
is usually the best for
relieving constipation. The hydroxide form draws water into the intestines to soften stool and stimulate
bowel movements. The intestines only absorb 4% of the magnesium from this form, which makes it a good option
for individuals that shouldn’t take magnesium supplements.
Magnesium for Constipation
Individuals often take magnesium supplements to relieve occasional constipation. Excessive amounts of
magnesium may cause diarrhea. However, chelated forms of magnesium bound to organic compounds like aspartic
acid are much gentler on the gastrointestinal tract and less likely to cause this side effect.
Potential Magnesium Side Effects
Magnesium is an essential mineral that individuals must obtain through dietary sources. Most individuals can
take magnesium supplements without experiencing adverse reactions. Some individuals may experience upset
stomach, nausea, or diarrhea. Magnesium supplements may interact with some antibiotics, diuretics, and heart
medications. Vitamin D3 (cholecalciferol) may interact with magnesium aspartate and increase magnesium blood
levels, particularly in those with impaired renal function. Individuals taking these medications or with
kidney disorders should consult a physician before taking magnesium supplements.
