Calm G Review 2019 – Benefits & Side Effects

Calm GWhat is Calm G

Calm G is advertised as a powerful brain supplement that was specially designed to promote healthy brain function by regulating normal glutamate levels, which may relieve anxiety and promote feelings of relaxation. Calm G is designed and manufactured by “NeuroScience” who claims that their product helps manage oxidative stress, modulates GABA-glutamate levels and protects against over-stimulation.

The company further argues that it is the most recommended supplement by neuro physicians to promote sleep and reduce anxiousness. Furthermore, this quality product is free from soy, salt, sucrose, corn, gluten, starch, yeast, artificial flavors, or artificial colors.

Calm G Ingredients

Calm G produced by Neuroscience contains the following ingredients: Folate (from 6S-5-methyltetra-hydrofolic acid, glucosamine salt) 150 mcg, Selenium (from L-selenomethionine) 70 mcg, and Proprietary Blend (N-acetyl-L-cysteine, L-theanine, Alpha-lipoic acid, and Coenzyme Q10) 1.1g.

Benefits of Calm G

The active ingredients in Calm G promote optimal brain function by promoting cellular energy, modulating glutamate signaling and managing oxidative stress, all of which help support neuron health.

The formulation of this product targets a neurotransmitter pairing that is responsible for optimal brain function. Glutamate is a primary stimulating neurotransmitter in the brain. It is an excitatory neurotransmitter that operates in conjunction with GABA (an inhibitory neurotransmitter), to provide balance within the neuronal circuit.

An imbalance between these two primary neurotransmitters can result in adverse effects on one’s brain health and overall well-being. Specifically, high glutamate levels can cause overstimulation of the neurons. Continued overstimulation can cause increased oxidative stress, decreased cellular activity, and neuronal death (excitotoxicity). Those with high glutamate levels may feel stressed, restless, anxious, or unfocused.

Calm G features theanine, which helps prevent excitotoxicity by blocking glutamate receptors, and N-acetylcysteine, which helps protect neurons from excitotoxicity by reducing intracellular glutamate levels while supporting the formation of the potent antioxidant, glutathione. This formula also contains Coenzyme Q10, another powerful antioxidant which helps promote cellular energy production, regulate glutamate levels and protect cell membrane lipids from oxidation.

Calm G provide feelings of relaxation, calm and focus on those with high glutamate levels. Its proprietary blend contains following additional key ingredients that may maintain healthy glutamate levels and reduce excitotoxicity.

Alpha-lipoic acid – blocks glutamate receptors and supports glutathione levels in the body which decreases glutamate levels and promotes feelings of relaxation.

Silicon – maintain normal glutamate levels and prevents oxidative stress to the cells of the body.

How Much Does Calm G Cost?

Compared to other similar supplements, Calm G produced by Neuroscience is relatively expensive. One 90 capsules bottle costs just under $65 and it will only last you for about 45 days considering the recommended dose of two capsules per day.

Potential Calm G Side Effects

Calm G is advertised as perfectly safe to use with no potentially dangerous side effects. However, as with all dietary supplements, Calm G is not recommended to pregnant or nursing women.

Please do not exceed the maximum recommended dose. In case of accidental overdose, call a doctor or poison control center immediately.


  • Calm G is used to support healthy levels of GABA, reduce anxiousness and promote sleep
  • Strong glutamate inhibitors in its formula modulate GABA-glutamate levels to protect against over-stimulation and help manage oxidative stress
  • N-acetyl-cysteine and alpha-lipoic acid may support normal reward pathways, increase glutathione levels and regulate urges and compulsiveness
  • Does not contain sucrose, starch, yeast, gluten, corn, soy, salt, artificial flavors, or artificial colors


  • If taken in high doses, may cause overstimulation in epileptic patients
  • It is relatively pricier than other supplements with almost similar results

Final Verdict

Calm G capsules stimulate healthy brain function and stop the process of neuronal death and damage with the help of Calm G proprietary blend. The exclusive blend helps to inhibit glutamate and prevent over stimulation.

By keeping the brain’s vital neurotransmitters in balance, this formula naturally helps the body to regulate stress. With Vitamin C, Selenium, L-theanine and Folic Acid, this exclusive formulation contributes to restoring the natural balance and thus provides feelings of calm, focus and relaxation.
