What makes this formula so effective?

Mg Optima Relax focuses on promoting the effects of Gamma-aminobutyric acid (GABA). GABA is a naturally occurring chemical in the brain (neurotransmitter). The main role of GABA is to have a calming effect on your nervous system. Magnesium - functions as a GABA receptor agonist promoting the effects of GABA.


Medlabs use the best quality Magnesium in the form of bisglycinate chelate. This means its highly absorbable and gentle on the bowels. Some brands use cheaper forms of magnesium which have a poor absorption rates.


Theanine - an amino acid found in Green Tea. It promotes relaxation via binding to glutamate receptors and inducing alpha wave (the normal electrical activity of the brain when conscious and relaxed) brain activity.


L-Glutamine - a precursor to GABA production, therefore enhancing the effect of the magnesium.


Pyridoxal 5 Phosphate (Vitamin B6) - is a vital cofactor for the enzyme Glutamate Decarboxylase that is essential in the synthesis of GABA.


Zinc – Along with many other health benefits Zinc is a modulator of both excitatory and inhibitory neurotransmission, therefore it plays an important role in maintaining and improving relaxation during times of stress.



Drugs such as Valium & Xanax work to enhance the effect of GABA, Alcohol is believed to mimic GABA's effect in the brain. Mg Optima Relax naturally assists the effects of GABA to calm the body.
