Why Mg Optima Relax?

Mg Optima Relax is quite literally a recipe for relaxation. Our main ingredient – Magnesium bisglycinate chelate – is highly bioavailable, which means our body can easily absorb this nutrient and utilise its benefits. For example, magnesium can increase the effects of GABA – a type of chemical messenger that blocks certain brain activity. By promoting the effects of GABA, magnesium has the effect of enabling the body and mind to relax, which can improve the quality of sleep throughout the night.

Glutamine and Vitamin B6 is required for GABA production, which further contributes to the relaxing effects of Mg Optima Relax. With L-theanine, a compound that is naturally found in Green Tea, it aids in relaxation without drowsiness by increasing GABA concentrations in the brain, which can support mental function, relieve nervous tension and support healthy stress response in the body.

  • Magnesium is primarily found within the cell where it acts as a counter ion for the energy-rich ATP and nuclear acids.
  • Magnesium is a cofactor in more than 300 enzymatic reactions. It critically stabilises enzymes, including many ATP-generating reactions. ATP is required universally for glucose utilisation, synthesis of fat, proteins, nucleic acid and coenzymes, muscles contraction, methyl group transfer and many other processes.
  • ATP metabolism, muscle contraction and relaxation, normal neurological function and release of neurotransmitters are all magnesium dependent.
  • Magnesium contributes to the regulation of vascular tone, heart rhythm, proper blood coagulation and bone formation.
  • Magnesium may modulate blood sugar regulation and cell proliferation in healthy individuals and is important for cell adhesion and transmembrane transport including transport of potassium and calcium ions.
  • Magnesium maintains the conformation of nucleic acids and is essential for the structural function of proteins and mitochondria.
  • Early signs of magnesium deficiency may include loss of appetite, nausea, vomiting, fatigue and weakness and as magnesium deficiency worsens it may be associated with numbness, tingling, muscle contractions and cramps.
  • Hypomagnesaemia is common in hospitalised patients.
  • Glycine is the major inhibitory neurotransmitter in caudal regions of the adult mammalian central nervous system with high densities of glycinergic synapses being found in spinal cord and brain stem.
  • Glycine has important neurotransmitter functions at inhibitory and excitatory synapses in the central nervous system.
  • L-theanine is one of the primary amino acids found in green tea and can pass over the blood-brain brain barrier increasing levels of concentration in the brain.
  • L-theanine can affect the secretion and function of neurotransmitter in the central nervous system.
  • L-theanine has an affinity to bind to the glutamate receptor subtypes. L-theanine blocks the binding of L-glutameric acid to the glutamate receptors in the brain, resulting in an anti-stress effect through inhibition of cortical neutron excitation.
  • L-theanine through competitive action against excitation of glutamate receptor subtypes, neurochemical studies suggest that L-theanine affects emotions by interacting with serotonin, dopamine and GABA neurotransmitter levels.
  • Dose-dependant administration of L-theanine may affect metabolism and/or the release of specific neurotransmitters in the brain.
  • L-theanine induces alpha wave brain activity, which relates to a perceived state of relaxation.
  • L-theanine may help to reduce anxiety levels and attenuate increased blood pressure in high-stress response adults.
  • L-theanine has a positive effect on mood and cognitive performance, resulting in increased energy, clarity of thought, efficiency, increased alertness and increased perceived work performance.
  • L-theanine may result in a reduction of heart rate and salivary immunoglobulin A responses during times of acute stress.
  • Zinc may function as an inhibitory neuromodulator of glutamate release in the brain.
  • Approximately 10% of total zinc in the brain exists in synaptic vesicles of glutamatergic neutrons.
  • Zinc is likely to modulate neurotransmission mediated via excitatory and inhibitory amino acid receptors at specific synapses.
  • Pyridoxal (B6) is involved in the regeneration of tetrahydrofolate into the active methyl- bearing form and in glutathione biosynthesis from homocysteine.
  • L-Glutamine is an amino acid precursor to the neurotransmitter GABA, the major inhibitory neurotransmitter in the central nervous system.


Always read the label. Follow the directions for use. If symptoms persist, talk to your health professional. Vitamin supplements should not replace a balanced diet. Contains less than 15 mg caffeine per 5 g dose.

Side Effects

Magnesium supplementation is likely well tolerated for most people but may cause stomach upset, diarrhoea, nausea and vomiting in some individuals.

Caution should be used in patients with kidney problems as poorly functioning kidneys do not excrete magnesium from the body well leading to dangerous levels of serum magnesium levels.

Vitamin B6 is toxic when ingested in mega doses i.e. greater than 200 mg per day for a prolonged period of time and may cause peripheral neuropathy

You can also refer to the CMI for this product for symptoms and side effects.


Concomitant use of magnesium and urinary excretion-reducing drugs, such as glucagons, calcitonin, and potassium-sparing diuretics, may increase serum magnesium levels, as may doxercalciferol. Concomitant oral intake of magnesium may influence the absorption of antibiotics (aminoglycosides, quinolone, tetracycline), bisphosphonates, calcium channel blockers and muscle relaxants.
