Magnesium is an inhibitory ion/mineral in the central nervous system and in muscle tissue. In muscle, magnesium counteracts the stimulating effects of calcium, which promotes muscle contraction. In the brain, magnesium counteracts the effects of excitatory chemicals, such as glutamine. To this end, magnesium exerts antagonism on the N‑methyl-ᴅ‑aspartate (NMDA) and has GABA agonist effects. Taurine: Taurine is an important amino acid in muscle tissue and in the nervous system, where it acts synergistically with magnesium, aiding its uptake in the cell. L-taurine also has affinity for the GABA(A) receptor, based on in vitro study.
