Which nutrient to dampen glutamate in manufactured food, except taurine?
I've got this info on my PC.
Several nutrients and compounds can help dampen the effects of free glutamate(MSG) in manufactured food, primarily by blocking receptors, assisting with conversion to GABA, or reducing neuro-inflammation.
Here are the key nutrients and compounds, excluding / in addition to taurine:
1. Primary Nutrients to Dampen Glutamate
Magnesium: This is considered a critical nutrient because it directly blocks the NMDA (N-methyl-D-aspartate) glutamate receptor, preventing the excitotoxicity caused by excess glutamate.
Vitamin B6 (as P5P - Pyridoxal 5'-phosphate): This is an essential cofactor for the enzyme Glutamate Decarboxylase (GAD), which converts excess glutamate into the calming neurotransmitter GABA.
Omega-3 Fatty Acids (EPA & DHA): These fatty acids, particularly DHA, are crucial for membrane health and have been shown to protect against MSG-induced neurotoxicity by supporting astrocyte function, which clears excess glutamate from the synaptic cleft.
Vitamin C : This acts as an antioxidant that attenuates NMDA receptor activity and helps increase glutamate reuptake from the synaptic cleft.
Vitamin E: As a lipid-soluble antioxidant, it helps reduce neuroinflammatory responses and increases the activity of glutamine synthetase, which breaks down excess glutamate.
Riboflavin (Vitamin B2): This supports the conversion of B6 to its active form (PLP) and helps prevent the buildup of neurotoxic homocysteine.
2. Functional Foods and Additives
Theanine: A compound found in green tea, it lowers glutamate activity in the brain by blocking receptors while also boosting GABA levels.
Ginger: Studies have shown that ginger significantly reduces MSG-induced elevated levels of glutamate, sodium, and calcium in the brain.
Curcumin (Turmeric): Known to attenuate MSG-induced neurotoxicity, reduce glutamate levels, and protect against inflammation.
Probiotics (Lactobacillus and Bifidobacterium): Specific strains express glutamate decarboxylase (GAD), which can convert ingested glutamate to GABA in the gut.
3. Other Protective Agents
N-Acetyl Cysteine (NAC): Helps the body regulate glutamate levels.
Zinc: Protective against neuronal excitotoxicity.
Coenzyme Q10: Reduces glutamate-induced cell death.

Excerpt
Riboflavin may also be able to directly affect excitotoxicity by inhibiting the exocytosis of glutamate vesicles in presynaptic neurons (Wang et al., 2008). Finally, riboflavin (along with PLP, folate, and vitamin B12) also has the ability to help protect against homocysteine build-up (Rozycka et al., 2013). Homocysteine has been shown to be neurotoxic via its ability to act as an agonist at the NMDA receptor (Deep et al., 2019), making riboflavin’s ability to reduce homocysteine very valuable.
Riboflavin additionally has the ability to protect against neuroinflammation. First, riboflavin was shown to effectively reduce TNF-α, IL-1β, and nitric oxide (NO) in a staphylococcus infection model (Dey and Bishayi, 2016). Riboflavin also plays an indirect role for opposing inflammation through its effects on vitamin D metabolism. Multiple enzymes in the biosynthetic pathway of vitamin D are dependent on riboflavin for their action (Pinto and Cooper, 2014). Animal models have been able to induce vitamin D deficiency from riboflavin deficiency due to this effect on the internal synthesis of vitamin D (Pinto and Cooper, 2014). Since vitamin D has anti-inflammatory effects (as detailed above), riboflavin deficiency may inhibit this protective function of vitamin D.
GABA: What Is It + Its Balance with Excitatory Glutamates

Excerpt
A 2020 study published in Translational Psychiatry has demonstrated that altering synaptic excitation-inhibition balance by potentiating GABA was associated with a significant reduction in ASD symptom severity (14).
Interestingly, the first nutrients in the biomedical world proposed for the treatment of ASD over 50 years ago by Bernie Rimland were magnesium and B6. Magnesium blocks glutamate uptake through the NMDA receptor and B6 (pyridoxine) is a GAD co-factor for converting glutamate to GABA. The amino acid taurine is also GABAergic and commonly recommended by functional medicine practitioners for children on the autism spectrum with behavioral issues and hyperactivity.
ASD = autism (stands for autism spectrum disorder => dissociative identity disorder).
