Quinoa
Overview
Quinoa is a pseudograin providing complete plant protein, magnesium, and when fermented in sourdough, can produce GABA through specific bacterial strains. Quinoa has a DIAAS score of 83-87, indicating high protein quality with complete amino acid profile (lysine marginal). Quinoa sourdough offers both very high nutrients (due to the quinoa) and a high GABA profile. Quinoa is mentioned as a source for choline support, important for vegans.

Preparation Notes
- Rinse before cooking to remove saponins (bitter compounds)
- Can be used in sourdough fermentation for GABA production; pseudo grains like quinoa, amaranth etc can introduce GABA and other important brain nutrients
- Pair with legumes to boost lysine content; combine with legumes to boost lysine for complete amino acid profile
- Part of grain-legume complementarity strategy
- Vegans should ensure adequate choline intake (e.g., soy or sunflower lecithin, soy foods, quinoa, broccoli) to support phosphatidylcholine synthesis
Biological Target Matrix
| Biological Target | Substance | Therapeutic Areas | Mechanism of Action |
|---|---|---|---|
| Endocannabinoid System (ECS) | Choline | Precursor for phosphatidylcholine (PC) synthesis; PE can be converted into PC or N-acyl phosphatidylethanolamines (NAPEs); NAPEs are precursors to N-acyl ethanolamines (NAEs) like palmitoylethanolamide (PEA), oleoylethanolamide (OEA), and anandamide (AEA), bioactive lipids which act as neuromodulators with anti-inflammatory, neuroprotective, and mood-regulating effects | |
| Hormonal Response | Magnesium | Supports calcium modulation along with vitamin D, taurine, phospholipids, and flavonoids; supports insulin sensitivity, sympathetic arousal, and mitochondrial excitability | |
| Inflammation | Zinc | Supports immune signaling; gut barrier integrity disrupted by nutrient deficiencies including zinc | |
| Insulin Response | Magnesium | Supports insulin sensitivity and glucose metabolism; magnesium deficiency is associated with insulin resistance; supports enzymes involved in glucose metabolism | |
| Insulin Response | Vitamin B1 (Thiamine) | Supports glucose metabolism and insulin sensitivity through mitochondrial function | |
| Methylation | Choline | Precursor to trimethylglycine (TMG/betaine), a dietary methyl donor that helps recycle homocysteine to methionine via an alternative pathway; supports one-carbon metabolism alongside folate, riboflavin, and B12; influences methylation dynamics relevant to MTHFR and COMT activity | |
| Methylation | Methionine | Essential amino acid that forms S-adenosylmethionine (SAMe), the universal methyl donor for neurotransmitter synthesis and membrane phospholipid methylation | |
| Methylation | Vitamin B2 (Riboflavin) | FAD acts as a critical cofactor for MTHFR, linking riboflavin to homocysteine recycling and methylation capacity | |
| Methylation | Vitamin B6 (Pyridoxine → PLP) | Essential cofactor in remethylation of homocysteine to methionine, which is converted to S-adenosylmethionine (SAMe); works with B2, folate, and B12 | |
| Methylation | Vitamin B9 (Folate; 5-MTHF) | Essential cofactor in remethylation of homocysteine to methionine, which is converted to S-adenosylmethionine (SAMe); SAMe fuels synthesis of dopamine, norepinephrine, and serotonin and drives phospholipid methylation in neuronal membranes | |
| Methylation | Zinc | Deficiencies in vitamins and minerals essential for methylation, such as folate, vitamin B12, and zinc, are correlated to ADHD symptoms; supplementing these micronutrients has shown potential in supporting methylation and reducing symptom severity | |
| Mitochondrial Support | Iron | Critical for oxygen delivery to the brain via hemoglobin; supports mitochondrial function and energy production | |
| Mitochondrial Support | Magnesium | Supports enzymes involved in glycolysis and the Krebs cycle (processes that generate ATP from glucose); binds to ATP and all triphosphates in cells to activate them | |
| Mitochondrial Support | Manganese | Supports mitochondrial antioxidant defense through MnSOD activity | |
| Mitochondrial Support | Vitamin B1 (Thiamine) | Essential for mitochondrial glucose metabolism in the brain leading to ATP production; supports PDH (pyruvate dehydrogenase) and α-KGDH (alpha-ketoglutarate dehydrogenase) function | |
| Mitochondrial Support | Vitamin B2 (Riboflavin) | Forms FMN/FAD coenzymes, supporting oxidative metabolism and redox balance; facilitates metabolism of B12, B6, and niacin; supports antioxidant enzymes | |
| Neurochemical Balance | Choline | Essential precursor for acetylcholine synthesis, supporting memory, learning, and neuroplasticity; supports membrane phospholipid biosynthesis (PC) which is critical for membrane fluidity and neurotransmitter receptor function; phospholipid methylation (PLM) alters membrane structure, facilitating faster neuronal recovery and influencing ion channel behavior in gamma oscillations linked to attention and cognition | |
| Neurochemical Balance | Iron | Essential cofactor for tyrosine hydroxylase, the rate-limiting enzyme in the conversion of tyrosine to dopamine; critical for catecholamine synthesis | |
| Neurochemical Balance | Magnesium | Broad cofactor for neurotransmitter synthesis and receptor modulation (e.g., NMDA, GABA); functions as an NMDA receptor antagonist and GABA receptor modulator; assists enzymes involved in synthesis of dopamine and serotonin | |
| Neurochemical Balance | Phenylalanine | Essential amino acid that converts to tyrosine and supports catecholamine synthesis (dopamine, norepinephrine); participates in LAT1 competition at the blood-brain barrier | |
| Neurochemical Balance | Tryptophan | Precursor for serotonin and melatonin; brain entry competes at LAT1 with other large neutral amino acids (LNAAs); carbohydrate-rich, low-protein meals raise the plasma tryptophan:LNAA ratio because insulin pushes competing LNAAs out to muscles; can feed NAD+ synthesis via the kynurenine pathway | |
| Neurochemical Balance | Vitamin B6 (Pyridoxine → PLP) | Cofactor for synthesis of dopamine, serotonin, GABA, and glutamate; supports rate-limiting steps in catecholamine synthesis; requires PDXK activation with magnesium and ATP support | |
| Neurochemical Balance | Vitamin B9 (Folate; 5-MTHF) | Supports neurotransmitter synthesis through methylation; cofactor for dopamine synthesis alongside iron, B6, and omega-3s | |
| Neurochemical Balance | Zinc | Important for DNA synthesis, cell division, and neurotransmitter regulation, particularly in modulating dopamine—a key neurotransmitter implicated in ADHD; acts as an allosteric modulator of the GABA receptor; supports glutamate regulation | |
| Oxidative Stress | Manganese | Essential cofactor for MnSOD (SOD2), supporting detoxification of superoxide within the mitochondrial matrix | |
| Oxidative Stress | Zinc | Essential mineral that serves as a cofactor for antioxidant enzymes; works synergistically with other antioxidants; heavy metals are detoxified by metallothionein (MT) metal carrier proteins that must bind with zinc and copper | |
| Stress Response | Magnesium | Helps manage stress responses; combined with vitamin D reduced behavioral problems; synergy with zinc and omega-3s reported |
